In the case of sand making machine price, sometimes the production capacity will be reduced. Why is this happening? Shanghai Shanqi technicians analyze the following aspects:

First of all, the effect of different stone materials crushed by the same sand making machine is different, because the hardness of stone in each area of ​​China is different. If the hardness of the material is large, the crushing process will be longer and the sand making machine will be vulnerable. The consumption of the parts is also larger, so it is necessary to customize the sanding machine's wear-resistant materials and models according to the different hardness of the stone material, which can effectively avoid unnecessary waste, and reduce equipment damage while reducing equipment downtime. The frequency of repairs, in disguise, increases the identity of the equipment, and achieves greater benefits for production engineering.

Secondly, the auxiliary equipment of the sand making machine should be in place. After repeated observations on the work of the sand making machine, the good grain size of the sand making machine is between 3 and 5 cm. The excessive and too small stone will affect the output of the sand making machine. Therefore, in the production process, the production of large stones should be equipped with a fine jaw crusher to supply the sand mill with a good grain type.

The third point is that the humidity and viscosity of the material will also have a certain impact on the sand making process. The material with too high temperature will have a certain viscosity or humidity, which will cause the equipment to become clogged during the production process. A sand making machine that does not block or is not afraid of viscosity materials.

The latter point is the power of the sand making machine motor. According to the model of the sand making machine, the equivalent motor should be equipped. The power should be strictly in accordance with the factory's factory requirements. Otherwise, the power level will not be reached or too high, which will cause the grain size of the sand making machine to be uneven. The amount of return is increased, resulting in a decrease in production.

What kind of role does the sand making machine play in the non-polluting vanadium extraction process? Originally, the stone coal vanadium ore beneficiation needs to go through multiple steps such as crushing and grinding, while the sand making machine equipment is broken and finely crushed by stone coal vanadium ore. Major equipment. The main methods of non-polluting vanadium extraction process include: acid extraction of vanadium pentoxide, extraction of vanadium pentoxide by salt-free roasting, and extraction of vanadium pentoxide by calcification roasting. No matter which method vanadium is used, the sand making machine equipment is the best ore crushing and crushing equipment.

In the process of extracting vanadium pentoxide by acid method, the sand making machine equipment is the core equipment of the crushing process, and is the key to promoting the efficiency improvement of the non-polluting vanadium extraction process. Ore crushing→ball milling→acid leaching→solid-liquid separation→pretreatment→extraction and extraction of vanadium→red vanadium pyrolysis→vanadium pentoxide. The sand making machine equipment can crush the stone coal vanadium ore to less than 5mm, and the fineness is uniform. The ability of non-crushing materials is strong, and the influence of moisture content of the material is small, and the moisture content can reach 8%. The simple structure of the sand making machine and low operating cost are very suitable for crushing ore of the stone coal vanadium ore beneficiation production line.

After the stone coal vanadium ore is crushed by the impact sand making machine, it is more than 80% by wet ball milling to a particle size of -60 mesh, and then continuously stirred with sulfuric acid which accounts for 15% of the ore mass. The temperature is 85 ° C, and the liquid solid product mass ratio ( 0.85 to 1): 1, vanadium is transferred to the solution in tetravalent form. After the solid-liquid separation, the slag is stacked, and the solution is pretreated, and then P 204 + TBP + sulfonated kerosene is used as an extractant, and subjected to a 7-stage tank type semi-countercurrent extraction, and then 1 to 1.5 mol/L sulfuric acid level 5 back extraction. A vanadium-containing solution having a mass concentration of 80 to 120 g/L is obtained, and red vanadium (ammonium polyvanadate) is obtained by heating and oxidation precipitation, and red vanadium is heated and decomposed at 550 ° C to obtain vanadium pentoxide.

In addition, the sand making machine plays a very important role in crushing and fine crushing in the process of extracting vanadium pentoxide by calcification roasting and extracting vanadium pentoxide by saltless roasting. The use of Henan SBM sand making machine equipment to crush stone coal vanadium ore is 50% more efficient than traditional ore crushing equipment, more efficient and environmentally friendly. The sand making machine equipment can also greatly improve the efficiency and comprehensive benefits of non-polluting vanadium extraction process.

The sand making machine has been used for a long time, and the crushing chamber will wear unexplained wear during use. What is the cause of this? Here, our SBM sand making machine engineers will come to analyze you one by one.

First, the number of broken materials entering the parallel area of ​​the sand making machine during the start of the sand making machine (sanding machine) was the highest, and it dropped sharply thereafter. Therefore, the parallel zone is subjected to intense wear and the parallel zone is gradually changed after several days of operation of the sand making machine.

Then, as the lining wears and the contour of the crushing chamber changes, the material that is broken along the height of the crushing chamber is evenly distributed. There is a change in the size of the crushing cavity in the limit wear range of the lining plate, especially the late parallel region does not exist, and the entire cavity shape completely loses the original contour. At this time, the size of the feed port is reduced by about 1.4-1.7 times, and the amount of material processed at the feed port is the largest. As the quality of the product deteriorates due to the absence of parallel zones, the output of the sand making machine equipment also decreases.

In summary, due to the uneven wear of the lining of the sand making machine, the crushing cavity loses the shape of the original crushing cavity, resulting in low life of the lining and a decrease in technical and economic indicators of the sand making machine. Therefore, the old-fashioned sand making machine crushing chamber should be improved. The new VSI sand making machine produced by our SBM Mining Equipment Co., Ltd. combines the advanced features of the impact sand making machine to draw on the advanced principle of the world sand making machine. The sand making machine adopts a variety of feeding modes, and utilizes two breaking principles of "stone rock" + "stone hitting iron". It can easily realize the flexible conversion of a variety of broken fine stone shaping functions. Compared with the traditional sand making machine, the sand making machine has low consumption of consumable parts and reasonable cavity design, reducing direct contact between materials and wearing parts. , to reduce the wear and tear of the wearing parts.

How does the new third-generation sand making machine achieve high-efficiency sand making? How often does the hammer and rotor of the third-generation sand making machine need to be replaced?

The new third-generation sand making machine is also called high-efficiency fine crushing machine. It is a new type of sand making machine (high-efficiency fine crushing machine) designed with reference to the working principle of various sand making machines and based on the feedback of users' specific use conditions and combining their advantages. The sand making machine equipment is compared with a conventional hammer sand making machine and a sand making machine. The sand making efficiency is higher, the hammer head wear resistance is stronger, the wearing parts of the equipment are used for a longer time, the equipment wear and maintenance rate are extremely low, and it is one of the most economical artificial sand making equipments. Compared with traditional craft equipment of the same scale, the sand making machine equipment has a production efficiency of 35%-50% higher, and the investment is lower than the traditional processing equipment of the same scale by 35%-50%. The long-term operation and maintenance cost of the equipment is lower than the traditional craft of the same scale. Equipment 35%-50%. g The sand making machine has a wider range of crushing.

The size of the discharge is adjustable to simplify the crushing process.

Tantalum is a mineral that contains metal strontium. The use of antimony ore is mainly used to produce antimony products. The use of lanthanum as a component of other alloys can increase its hardness and strength. The process flow of Yankuang mineral processing equipment should be based on the physical and chemical properties of the type of ore, mineral composition, mineral structure, and inlaying properties as the basic conditions to be selected, and the content of valuable components and the requirements for the application of antimony metallurgy technology should also be considered. And the final economic efficiency and other factors. Sulphide antimony ore is one of the most common antimony ores. Sulphide antimony ore beneficiation is usually carried out by flotation process. South Africa is rich in antimony ore resources, and it is necessary to use various ore-dressing equipment for ore-bearing ore selection. Ore crushing and crushing equipment are naturally indispensable. The new sand making machine is also called the efficient crusher and can easily crush the antimony ore to less than 5mm. It is the best equipment for crushing fine ore.

The new type of sand making machine plays an important role in the whole process of the beneficiation ore dressing production line. The Xenon ore flotation process consists of jaw crusher, sand making machine, ball mill, classifier, magnetic separator, flotation machine, thickener and Dryer and other equipment components. The sulphide bismuth ore mined is first broken by the main jaw crusher in the ore processing equipment, and then enters a new type of sand crusher for fine crushing. After being finely crushed to a reasonable fineness, it is evenly sent to the ball mill through the lifter and feeder to be mined. The equipment ball mill grinds and grinds the ore. The ore fines milled by the ball mill enter the next process: grading. Spiral classifiers clean and classify ore mixtures based on the principle that the specific gravity of solid particles is different and the rate of precipitation in liquids is different. After washing and grading, the mineral granules after preliminary separation are sent to the flotation machine, and different drugs are added according to different mineral characteristics, so that the desired minerals are separated from other substances. After the desired minerals are separated, because they contain a large amount of water, they must be initially concentrated by a thickener and then dried by a dryer to obtain dried minerals. The new sand making machine can be used to crush the ore to less than 5mm, the processing volume is large, and the fine crushing effect is good, which can greatly reduce the fine crushing of the material entering the ball mill equipment, realize more broken and less grinding, and greatly improve the grinding efficiency of the ball mill equipment. The new sand making equipment has less investment, low freight and operating costs, and is 30% more efficient than the traditional fine-brick crusher, sandblasting machine and hammer crusher, and is more energy-saving and environmentally-friendly. It is currently the most popular ore crushing equipment for the ore beneficiation production line.

What are the advantages of using a new type of sand making equipment to crush ore?

The new type of sand making machine has various types of equipment, large feed granularity, and fine material discharge, which can meet the requirements of ore fines for various ore dressing production lines. The processing capacity of 20-500t/h is suitable for different scale ore crushing production line processes. The sand making machine has high crushing efficiency and has fine crushing and coarse grinding functions. Applicable to different hardness ore crushing operations. The structure is simple, installation and maintenance are convenient, and the operating cost is low. Through the non-broken material ability, the impact of the moisture content of the material is small, the moisture content can reach 8%. Low working noise and less dust pollution. Is an ideal ore miner.

The sand making machine is the core equipment of the mechanism sand production line, while the sand stone production line is the core equipment of the sand field (quarry). The sand and gravel factory refers to the mining, production and supply units of construction sand and building stone. It belongs to enterprises and is built on many waterways. Inland areas are mostly built on rivers and lakes, and large-scale marine sandstone mining is built according to the sea. The production process of sandstone is mainly divided into two processes, namely mining and selective grading. Its fixed locations are mostly used for storage and selected grading. A medium-sized production enterprise can produce about 100,000 tons of sand per year, and large-scale enterprises can produce annual production capacity of one million tons. Many quarries will become ponds or lakes, or landfills, when they are abandoned. Below we will detail the design principles of sand and gravel plants and stone yards:

First, the sand machine equipment yard setting principle

The gravel plant and the stone material yard refer to the large-scale storage facilities mainly based on the ore blending and mixing of raw ore, which are more common in the metallurgical, chemical, building materials and other industrial sectors. The main purpose is to solve the problem of homogenization of the raw materials and the selected raw materials, so it is also called the neutralization stockyard. In practical applications, the ore grade is neutralized, the fluctuation of the selected grade is reduced, and the beneficiation index is improved. Most of the gravel plants in the northern region are located near river courses and in the river channels in Gangu. Set the yard generally under the following conditions:

(1) The mine's resources are insufficient. Ore must be purchased from outside, and the nature of the purchased ore and the quality of the ore are very different. It is not possible to set up a neutral material yard, and it is difficult for the mineral processing plant to produce normally;

(2) The resources of the mine are abundant, but the material composition and mechanical and physical properties of the ore vary greatly, and it is difficult to ensure the requirements of the concentrator in the mining method;

(3) Mines located in severely cold areas, due to the influence of the transportation system, cannot transport ore stone in winter, and the ore grade changes are relatively large;

(4) There are many kinds of raw materials. According to the process requirements, various raw materials must be fed into certain operations according to a certain proportion, and a neutralization stockyard is also required. Such as metallurgical plants, cement plants, building materials plants, etc.

The large-scale special neutral sand making machine has a large investment and a large area, and it is rarely used in the design of the concentrator. For a concentrator with adequate resources and little ore fluctuations, the method of expanding the volume of the intermediate ore storage in the selective plant can be used instead of the complex medium-duty yard. Small-scale ore dressing plants with small ore purchases may consider artificial neutralization methods and set up small stockyards.

Sand machine equipment stockyard form selection

The neutralization stockyard generally consists of a distribution and reclaiming system, a material pile, a conveying system, a sampling, metering and inspection system. Determine the form according to the nature of the material and the requirements of production.

(1) Storage time of the stockyard: Determine according to the type of stone material, the required neutralization effect, the transportation conditions, and the buffer capacity required. Generally 7 to 10d, depending on the size.

(2) Stacking method: According to different process sand production line process requirements, the stacking method can be divided into herringbone layered stacking method, wave-shaped partitioning method, herringbone and wave-shaped composite stacking method, long strip pile Material method, etc.

The herringbone layered stacking method has a simple cloth distribution method, has no special requirements for cloth equipment, and is suitable for fine-grained materials; the wavy-shaped partitioned material stacking method has complicated fabrics and strict requirements on the stockpiling equipment, but has less segregation phenomenon and is suitable for bulk materials. The other method is somewhere in between. Due to the complexity of the cloth method, only when the demand for neutralization is high is considered.

The roller type sand making machine refers to the equipment that uses the roller crusher to produce the machined sand. The advantage of sand making on the roller type sand making machine equipment is that the equipment has fewer wearing parts, high wear resistance, and high sand production rate. The roller-type sand making machine produced by our factory is not only durable, uniform sand particles, and less crushing phenomenon, but also is the first choice for high-strength rock sands such as pebbles and quartz. The sand machine replaces a hammer for several hours. How can we further improve the production rate of the roller sand making machine and improve the sand production rate?

Adjusting the discharge granularity of the roller type sand making machine: There are wedge-shaped or gasket adjusting devices between the two rollers. The top of the wedge device is equipped with adjusting bolts. When the adjusting bolts lift the wedge upward, the wedge will move. The top of the roller is away from the fixed wheel, that is, the gap between the two rollers becomes larger, and the size of the discharged material becomes larger. When the wedge is down, the two rollers of the movable roller become smaller under the action of the compression spring, and the discharge granularity becomes smaller. The gasket device adjusts the size of the material by increasing or decreasing the number or thickness of the gasket. When the gasket is increased, the gap between the two rollers becomes larger. When the gasket is reduced, the gap between the two rollers becomes smaller and the particle size of the discharge becomes smaller. . According to different requirements, the distance between the rollers can be adjusted to produce sand with different specifications such as coarse sand, medium sand and fine sand. In addition, the following five major points must be taken into consideration when using the roller type sand making machine:

1. The viscous material can easily clog the crushing space. The clogging should be stopped in handling the clogging fault.

2. After the roll sand making machine is operated for a long time, due to the large abrasion of the roll surface, it will cause the product granularity to be too fine. At this time, attention must be paid to adjustment of the discharge port or overhaul of the equipment.

3, when the processed material contains large blocks, pay attention to large ore easily squeezed out from the crushing space to prevent injury or damage to equipment.

4, to strengthen the inspection of the equipment, the lubrication of the equipment should be on time, to maintain a good lubrication of the equipment.

5, to strengthen iron ore removal work. Non-crushed objects (bits, etc.) falling into the gap between the rollers will damage the sand making machine, causing a parking accident. Therefore, the iron removal device should be installed before the crusher.

Which type of sand making equipment is suitable for light calcium carbonate crushing? Light calcium carbonate is produced by chemical processing. Because its settling volume (2.4-2.8 mL/g) is greater than mechanically produced ground calcium carbonate sediment (1.1-1.9 mL/g), it is referred to as light calcium carbonate. SBM's new type of sand making machine is a new type of high efficiency, widely used in the crushing and crushing of various raw materials such as rock, ore, cement clinker, and refractory materials. The sand making machine is also ideal for the crushing of raw materials in the light calcium carbonate processing industry.

Light calcium carbonate is produced by calcining limestone and other raw material segments to produce lime (mainly composed of calcium oxide) and carbon dioxide, and then adding water to digest lime to produce lime milk (mainly composed of calcium hydroxide), and then adding carbon dioxide to carbonized lime milk to generate calcium carbonate. Precipitation, and finally by dehydration, drying and crushed prepared, or first with sodium carbonate and calcium chloride metathesis reaction to produce calcium carbonate precipitate, and then by dehydration, drying and crushed prepared. Among them, the sand making equipment plays an important role in the entire light calcium carbonate processing. The sand making machine has characteristics of small particle size, uniform particle size, large production capacity, long hammer life, small supporting power, variable three-stage crushing, secondary crushing, simplified process, simple structure, convenient maintenance and stable operation. The use of the sand making equipment to crush finely divided calcium carbonate precipitates is ideal. The fineness of the sand making machine equipment can reach 5mm or less, which is very favorable for the industry efficiency of the calcium carbonate milling production line.

In addition, SBM's new sand making machine equipment has many advantages such as environmental protection and energy saving. The sand making equipment works with low noise and no pollution. The unique air self-circulation system greatly reduces the amount of exhaust air, reduces dust, and is environmentally friendly. The sand making equipment is reserved and suitable for installing a variety of dust removal equipment. It is very beneficial to the entire calcium carbonate milling production line industry to achieve energy conservation and emission reduction.
