High yield and high yield are the pursuit targets of sand and stone manufacturers. With the continuous updating of sand making equipment, existing There are a large number of optional models on the sand making equipment market, which can meet the unsatisfactory sand making needs. It seems that it is not impossible to produce high yield and good quality. The key is that you can choose the right ore sand making machine.

How to achieve high yield and quality of ore sand making machine

If the ore sand making machine wants to achieve high yield and high yield, then the matching of the machine type must be selected. The equipment is not necessarily expensive. According to your actual production needs, refer to the nature of the material and choose the sanding requirements. Models and specifications should also be selected. The models are too big or too small. It is too easy to overload and operate, which affects superior production. Excessive no-load is easy to cause power waste and high production cost. Therefore, before equipment matching, You must clearly understand the nature of your materials, production conditions, finished product requirements, and then choose according to local conditions.

How to choose the sand machine model

The common models of the sand making machine are not only the traditional straight-through impact sand making machine, but also the three models of HVI, TK and VSI. The working principle of each type is different, and the finished sandstone is also different.

HVI sand making machine

At the same time of sand making, plastic processing can be realized. The finished sand and gravel tastes well and the particle size is uniform. The two feeding modes can be flexibly converted, high yield or superior yield, which is up to you;

TK sand making machine

The principle of stone stone is adopted, the work cost is lower, the wear is small, the service life is long, and the interaction between materials can optimize the grain shape. If you pay attention to the finished grain type and want superior production, you can choose TK sand making machine;

VSI sand making machine

It is to use the working principle of stone striking iron, the impact speed range is larger, the sand making efficiency is high, and if you want high yield, it is right to choose it;

Straight through impact

On the basis of the traditional sand making process, the structure is improved and the sand making is more environmentally friendly.

The machine-made sand refers to the sand processed by the sand making machine and other ancillary equipment. The finished product is more regular, and can be processed into different rules and sizes of sand according to different process requirements, which can better meet daily needs. In recent years, with the increasing demand for infrastructure construction in China, the output of machine-made sand has increased year by year, and the number of sand-blasting yards and stone yards for producing mechanism sands is also increasing. However, the contradiction between the large-scale production of mechanical sand wastewater and environmental protection and water conservancy and flood control has become increasingly prominent. How to effectively treat the mechanism sand wastewater and realize the environmentally friendly production of the mechanism sand? Here we will introduce you in detail.

Due to the large amount of mechanical sand wastewater, high solid content in wastewater, wide particle size distribution of solid particles, difficulty in wastewater treatment, high equipment investment and high operating costs.

The rotor is the heart of the sand making machine price. It is the most important working part of the sand making machine and the most vulnerable part. Whether it is a cobblestone sand making machine or a river gravel sand making machine, the rotor is very important. Therefore, the rotor is the most strict part of the sand machine acceptance. Our company has developed a sturdy heavy-duty rotor made of a new high-strength wear-resistant alloy to obtain a higher moment of inertia, and the latest design technology to optimize the crushing cavity of the sand making machine. The following is a brief explanation of the precautions for the installation of the rotor of the sand making machine and the damage factors of the rotor of the sand making machine.

Analysis of damage factors of sand making machine rotor

The sand making machine is powered by the motor after the power is turned on. The power is transmitted to the rotor through the bearing and the gear. The rotor rotates the crushed aggregate at a speed of 186 rpm. Among them, there are two factors that affect the wear of the rotor.

1. The cooperation relationship between the rotor and the bearing. The rotor bearing of the sand making machine is mainly subjected to the impact load during operation. The magnitude of the load on the rolling element is different. The rolling element under the combined action of the impact load is subjected to a large force, and the inner and outer ring raceways are also in the Here, the force is greater when it comes into contact with the rolling elements.

2. The bearing condition of the rotor bearing The impact load of the VSI sand making machine on the bearing depends on the impulse acting on the rotor and the support flexibility of the bearing seat. Increasing the support flexibility of the bearing seat can reduce the impact on the bearing. Load, therefore, adding a rubber plate of appropriate thickness between the bearing of the sand making machine and the support frame can improve the support flexibility of the bearing seat and improve the bearing condition of the bearing to achieve the purpose of prolonging the service life of the rotor.

Let us first introduce the hammer sand making machine. Hammer sand making machine, also known as hammer crusher, is mainly used to crush minerals of various brittle materials. The materials that are forced to be aged are coal, salt, stone bone, alum, brick, Tile, limestone, etc., the compressive strength of the material does not exceed 1500 kg / cm2, humidity is not more than 15%, let's talk about the common faults and solutions of the hammer sand machine.

Possible failure (1): The amount of vibration increases. Cause of failure: The rotor is not well balanced when replacing or assembling the sander hammer. Elimination method: remove the hammer and select the hammer by weight so that the total weight of each hammer is equal to the total weight of the hammer on the hammer shaft.

The fasteners are loose, the hammer hits the liner. 3. Hammer or other parts Breaking. Elimination method: 1. Clean the crushing chamber after parking 2. Check the fastening of the liner and the gap between the hammer and the sieve. 3. Replace broken parts

Everything is not pre-emptive, and it is helpful to understand the common faults and solutions of the sand making machine linkage line. It is beneficial to the correct operation of the sand making machine equipment. The sand making machine needs to pay attention to many problems during the use or installation process. The most concerned is the problem of the sander connection line. So what is the connection line of the sand making machine, and what are the common problems of the sand making machine connection line?As we all know, if we take the wrong connection line of the sand making machine, it will cause a lot of trouble, and sometimes even burn out our equipment, so Henan Shisheng will summarize the maintenance and connection of the wiring of the sand making machine. Key points:1. The maximum load current through which the wire of the sand making machine, sanding machine, etc., passes should not exceed the allowable current of the ride.2. The fixing frame and the fittings of the successive sand making machine (sanding machine) shall be free from serious rust and deformation and decay. The rust of the fixture's fittings should not be peeled off and there should be serious pitting, and the rust surface area should not exceed 1/2.3. The joint of the steel strand (ground) is free from discoloration and severe corrosion. The bolts of the connecting clamp should be firm, and the strand (bottom line) should be free of strands.4. The suspension stress of the low-voltage overhead cluster line should be smooth, and the distance between the conductor brackets must not exceed 1M.5. The end of the bundling line of the sand making machine should be well sealed.6. The insulation layer of the cluster wire should be well-rounded, without peeling and cracking.7. The connector and cable clamp should be free from overheating.

With the release of the natural sand resource limited mining policy, artificial sand is becoming more and more important in engineering construction, and the sand making machine equipment for manufacturing artificial sand has also been favored by everyone.

The cleaning and maintenance of the sand making machine has attracted more and more attention with the rise of the sand making machine. After all, more than 90% of the operation in the sand making machine is stone material, so the residue will be left in the process of producing sand and gravel. Inside, when these residues accumulate to a certain extent, it will affect the operating efficiency of the entire machine and the life of the machine, so it must be cleaned regularly.

There are two main methods for sand making machine cleaning, which are pickling and the second is alkaline washing. When pickling, firstly prepare a hydrochloric acid solution at a concentration of about 20%; after the hydrochloric acid solution is prepared, pour it into the dirt, wait for about ten minutes, and then rinse with other cleaning solution; when using the alkaline washing method, First, the caustic soda, gasoline and water are prepared in proportion, and in the process of cleaning, the cleaning rod is continuously used to treat the dissolved dirt. When the dirt is dissolved, it can be cleaned with water.

However, it is especially pointed out that the proportion of the acidic solution or the alkaline solution must be mastered during cleaning. Only in this way can the cleaning effect be exerted without affecting the machine itself, and only regular cleaning can ensure the operation of the entire machine. Efficiency is normal and its life is extended.

Artificial sand has become the main source of sand for infrastructure construction such as modern buildings, highways, high-speed rail and water conservancy projects. The artificial sand making machine is the artificial sand making equipment, that is, the sand making machine equipment. The price of the sand making machine is related to the customer's needs. Let's take a granite sanding machine as an example to introduce you in detail, the selection of granite sand making machine and the price of granite sand making machine.

Granite is a type of igneous rock formed by the formation of magma below the surface. The main components are feldspar and quartz. The source of granite is the Latin granum, meaning grain or granules. Granite is not easy to weather, beautiful in color, and its appearance can be kept for more than 100 years. Due to its high hardness and wear resistance, it is used as the first choice for high-end architectural decoration projects, hall floors, and open-air carving. The hard texture of granite is also an ideal material for the production of high quality artificial sandstone aggregates. Due to the high hardness of the granite, the wear on the equipment will be severe. Our SBM recommends that you choose a sandblasting machine with high abrasion resistance. Sander equipment such as PCL impact sand making machine, new third-generation sand making machine and VSI new sand making machine are ideal equipment for rock crushing and fine crushing sand with high hardness such as granite, river pebble and basalt. In particular, VSI's new sand making machine is made of high-quality wear-resistant materials. The advanced sand making principle can easily realize the crushing and fine crushing of granite and stone shaping.

Our SBM also offers a complete line of granite sand production lines. It is specially designed for granite crushing and sand making. The main equipments are vibration feeder, jaw crusher, impact crusher, VSI new sand making machine (or new third-generation sand making machine), sand washing machine, vibrating screen and tape conveyor. According to different process requirements, various types of equipment are combined to meet different process requirements of customers. Among them, E-break and impact crusher are crushing equipment with high wear resistance. It can effectively crush the granite to the appropriate feed size of the sand making machine.

With the development of the times, the advancement of science and technology, artificial sand equipment (sand making machine) is constantly upgrading and optimizing, how much is the artificial sand making equipment? Which sand making machine is better? Which kind of sand making machine is used for granite sand? Many customer needs, welcome to consult SBM sand making machine experts, dedicated to serve you!

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? The machine engineer 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.

Which sand making machine is used for asphalt concrete and cement concrete aggregate production?The sand and gravel aggregate for concrete has strict requirements on sand, and the high quality sand making machine is the key to ensure high quality artificial sand. Our SBM recommends a new high-efficiency sand making machine designed for the processing of high quality concrete gravel aggregates.SBM high-efficiency energy-saving sand making machine (impact sand making machine) consists of seven parts: feeding hopper, distributor, vortex breaking chamber, impeller body, spindle assembly, base, transmission and motor. This series of sand making machine is suitable for the crushing and shaping of soft or medium hard and extremely hard materials. It is widely used in various ores, cement, refractory materials, aluminum clay clinker, silicon carbide, glass raw materials, mechanism construction sand, stone and each Metallurgical slag, especially for high hardness, special hard and abrasion resistant materials such as silicon carbide, silicon carbide, sintered bauxite, and beautiful sand, is more effective than other types of crushers.SBM new high efficiency sand making machine works:The material enters the sand making machine from the feeding hopper, and the material is divided into two parts by the feeder, and a part is inserted into the high-speed rotating impeller from the middle of the distributor, and is rapidly accelerated in the impeller, and the acceleration can reach hundreds of times of gravity acceleration. Then, it is ejected from the three uniform flow channels of the impeller at a speed of 60-70 m/s. Firstly, it is impacted and broken by a part of the material falling from the periphery of the distributor, and then impacted together on the material lining in the vortex cavity. It is rebounded by the material lining, impacts obliquely upward to the top of the vortex chamber, changes its direction of motion, deflects downward, and the material emitted from the impeller runner forms a continuous material curtain. Such a material is subjected to two or even multiple chances of impact, friction and grinding and crushing in the vortex breaking chamber. The broken material is discharged from the lower discharge port. In the whole crushing process, the materials are crushed and broken by themselves, and are not directly in contact with the metal components, but are impacted, rubbed and pulverized with the material lining, which reduces the angular pollution and prolongs the mechanical wear time. The ingenious airflow inside the vortex chamber self-circulates, eliminating dust pollution.The sand making machine has a novel, unique structure and stable operation. The sand making machine (sanding machine) has low energy consumption, high output and large crushing ratio. The device is small in size, easy to operate, and easy to install and maintain. The sand making machine (sanding machine) has a shaping function, the product is cubic, and the bulk density is large. During the production process, the stone material can form a protective bottom layer, and the body is wear-free and durable. It is an ideal production equipment for mechanical sand, cushion material, asphalt concrete and cement concrete aggregate. It is the best equipment for producing the most efficient sand production. With SBM's new high-efficiency sand making machine, high-quality artificial sand processing is no longer a problem.
