In the ore milling production line, an inadvertent misuse, an unintentional neglect, will cause the production error to widen. The fineness of the heavy calcium ultrafine mill is arbitrarily adjusted between 300 mesh and 2500 mesh. According to the user's reflection, Shibang Industrial Technology Group analyzes why the fineness of its production is not up to standard. The main reason is ?First of all, let's take a look at the composition of the heavy calcium superfine mill. The complete set of equipment includes hammer crusher, bucket elevator, storage bin, vibrating feeder, superfine mill host, frequency classifier, double The cyclone dust collector, pulse dust removal system, high pressure fan, air compressor, and electrical control system are realized by the combination of the entire line.First, the speed of the fan of the heavy calcium ultrafine mill affects the fineness of the discharge. In the process of milling, if the speed of the fan is too high and the wind is too large, the material that does not meet the fineness requirement will be blown into the powder collector. Conversely, if the material has a large specific gravity, the wind will be too small. Affects the discharge, which in turn affects the overall fineness. This requires us to adjust the motor and current to achieve the adjustment of the fan speed.Second, in the analysis machine of the heavy calcium ultra-fine mill, a large number of blades are installed. These blades will wear after a period of use, which directly affects the efficiency of the analyzer. Operators should pay attention to the maintenance during maintenance. Once the blade wear phenomenon occurs, it should be replaced in time to avoid affecting the quality of the milling.Third, under normal circumstances, the production of medium-heavy calcium ultra-fine grinding machine grinding roller and grinding ring is not in direct contact. However, as the use time of the equipment increases, the degree of friction between the grinding roller, the grinding ring and the material increases, and the wear degree of the grinding ring increases. The material is not fully ground and the fineness of the finished product is affected. The operator should record the service life and replacement cycle of the grinding roller ring and replace the new fittings regularly.In short, there are many factors affecting the fineness of the super-calcium superfine mill. In normal applications, only correct operation is carried out, and the equipment is carefully maintained and maintained to better ensure the quality of the mill. Once the fineness of the heavy calcium ultrafine mill is not up to the requirements, it is necessary to check the cause in time, and prescribe the right medicine to ensure the quality of the powder.

The European version of the ultrafine mill includes the main mill, analysis machine, fan, electric control cabinet, etc., except for the mainframe, all of which are auxiliary machines. Recently, customers have asked us if we can change the lower dust collector because of the site restrictions. s position.

The customer now wants the other parts to move, and wants the toner collector to move 90 degrees, which can reduce the curvature of the pipe after the powder is discharged. The idea is good, but it is not feasible.

why? Because the position of each auxiliary machine next to the main mill is a good match after long-term production test, the current position is good. Once one of them is moved, it must be moved. This is not just a matter of changing the process. It is necessary to change all drawings, otherwise it will affect the overall production effect.

Therefore, the European version of the ultra-fine mill can not change the position of the auxiliary machine at will, so the cost of buying two sets of grinding machinery, and not because of small loss.

The working condition of the European version of the mill is very bad, we must do regular maintenance and maintenance, otherwise it will seriously affect the service life of the accessories, not only bring trouble to the entire ultra-fine grinding production line, but also bring you huge Economic losses.

The European version of the ultrafine mill model has more bearings, each bearing is not the same way of maintenance, but each bearing is either using No. 1 grease or using sodium bitter grease for lubrication, please be sure to ensure that the grinding mechanical bearing per The oil should be added once every eight hours, the blower bearings should be refueled once a month, and the main engine center bearings should be refueled once every four shifts.

In addition to the regular lubrication of the lime powder superfine mill bearings, we should also pay attention to the temperature of the bearing chamber, which cannot exceed 70 degrees. When the bearing is found to be overheated, we should disassemble the cleaning bearing so that the grinding machine can operate well.

With the development of science and technology, it has driven the rapid development of China's milling industry. The performance of ore milling machine has also been greatly improved, and the types of materials that can be ground are also increasing. However, in spite of the use of ore mills in the process of use. There are still certain constraints. For example, the material size of the ore mill must not be too large. For this problem, the user of the Shanghai SBM has given detailed instructions when purchasing the milling equipment, but the user There will definitely be doubts, what effect does the feed material have on the ultrafine mill?

The accessories of the ore mill generally include a plum blossom frame, a grinding roller, a grinding ring, a blade, etc. When a large piece of material enters the grinding chamber, the material handling capacity of the machine is in a certain condition, and as the material is continuously fed, As a result, the throughput of the machine cannot keep up with the amount of material delivered, so that these materials accumulate in the grinding chamber, causing the product's powder passage to be blocked, resulting in serious production failure. Therefore, if the material is too large, it may cause the machine to block the material, thereby hindering the production efficiency, and the serious situation may damage the machine.

In addition, if the ultrafine mill feed size is too large, it may cause the fineness of the powder to increase. The fineness of the powder in this case refers to an increase in the proportion of the low-fineness material of the collected powder material, because the fine particle size of the ore is a relatively small range when the powder is produced by the ultrafine mill. Within this range, as the feed particle size increases, the proportion of the treated larger powder material that can be blown away by the wind increases, so that the proportion of the larger particle size powder material passing through the classifier increases.

Also, in the production process of the ore mill, if the feed particle size increases, the failure rate of the machine will increase, which is undoubted, because the force of the bulk material on the ore superfine mill accessories will also increase, and Among these accessories, there are three main types of wearer parts: the roller sleeve, the grinding ring and the blade. Because these parts are in direct contact with the material, they wear more than expected and reduce the service life of the user parts. , seriously affecting production efficiency, thereby increasing the investment cost of users.

Excessive feed particle size on the surface is not conducive to the normal operation and fineness of the ore mill, but in the long run, it will also affect the service life of the ore mill accessories and the life of the ore mill. Therefore, here Shanghai SBM recommends that the majority of users in the processing of large ore, you can first use the crusher to crush it into the size of the ultra-fine grinding feed particle size and then use the grinding equipment to grind, which not only reduces the ore mill The grinding burden, material fineness is also guaranteed, and the production efficiency is greatly improved.

In the end, the quality of the mechanical equipment produced by SBM must be strictly controlled. Under the premise that corporate customers cooperate with the routine maintenance of ultrafine mill, the service life of ultra-fine mills can greatly exceed the expected range. So how do corporate customers change their daily maintenance? First of all, as a high-energy-consuming product equipment, ultrafine grinding mills can't avoid high power consumption, but companies can effectively reduce energy consumption and sing the life of machinery by replacing oil. Secondly, the ultra-fine mill equipment itself has very serious wear and tear. The super-fine mill wearing parts produced by our company use special hard and wear-resistant materials, but in use day after day, year after year, no matter how good The wear-resistant materials also cannot be used excessively, so even changing the wearing parts is a point that the company must perform in daily maintenance work. Here our company advises companies to replace consumables regularly and in accordance with our recommendations. The last point is also very important. Mining machines such as ultra-fine mills are generally made of steel plates that are cast or welded. This means that the possibility of rusting is very high. It is well known that rusting of mechanical products is serious. It directly affects its service life, so our company recommends that companies choose dry and ventilated places to place equipment for production.

The liner of the ultrafine mill is used to keep the inner wall and the end cap of the ultra-fine mill barrel from being abraded by the grinding body, and to some extent increase the rigidity of the cylinder body. Play an important role in the machine. Therefore, when choosing the liner, we should strengthen the understanding of the liner material. The following is the introduction of the material of the ultrafine mill liner.

Classification of materials

1, high manganese steel: high manganese steel (ZGMn13) in the chemical composition of Mn content of 12% to 14%, the original surface hardness of HRC20 ~ HRC25, during the work process, due to the impact of the lining plate ball, can increase its surface hardness To HRC40 or more. In large-scale ultra-fine mills, manganese steel liners are often deformed due to severe impact, resulting in damage to the ultra-fine mill barrels. Therefore, manganese steel liners should be used in small and medium-sized ultra-fine mills.

2. High-chromium alloy cast steel liner: It has high original hardness equivalent to wear-resistant white cast iron, and has certain toughness. It has higher wear resistance under lower impact force, compared to other materials. The statement has a higher price/performance ratio and can be used in large, medium and small ultra-fine mills.

Material requirements

First, the material of the ultra-fine mill liner should be able to improve the grinding process of the ultra-fine mill, and the second is to select and handle the liner material. The requirements for the liner should have a high impact fatigue durability, can withstand a certain strength of the impact. In addition, the hardness, structure, and composition of the entire liner are uniform. In the use of low wear rate, the use of the process is not deformed, not broken advantages.

Liner material cost

The cost of liner materials is an important factor to consider when manufacturing liners. In particular, it is more important to use low-grade ores, low-grade ores, or low-cost materials such as cement. The total cost of liners should include Material requirements and installation costs, in most cases, also include the cost of relining board parking, which is measured in the form of lost production.

Material heat treatment process

No matter what type of liner is used in the ultra-fine mill, the material of the liner must be extremely hard in order to function and use it in the machine. The material of the liner must have a heat treatment process, otherwise the cracks may appear in the work liner, and the liner material after the heat treatment process rarely occurs. When choosing a building, you should strengthen your understanding and choose the material that is most suitable for the ultra-fine mill liner.

The performance of an ultra-fine mill depends to a large extent on the performance of the parts. For example, the quick wear of fittings will affect the production efficiency of the entire mill production line, and how to extend the service life of ultra-fine mill parts. What?

Bear the brunt of its normal wear and tear, ultrafine mill accessories including grinding roller, grinding ring, blade, etc., these must be considered when buying, you can consult the manufacturer, which ultra-fine grinding machine parts wear fast, buy When more than one set, in case of need. Here, we must remind customers, in the purchase of equipment, we must check the quality of the products, these wear parts, some manufacturers use high-chromium materials, some with high-manganese materials, some will directly use ordinary materials This can make a big difference in use.

This is often the case, users only consider the price at the beginning of the purchase, the other to ignore, use a period of time to find problems, new equipment, before the investment is not thrown, this time to consider taking some Protective measures to avoid excessive wear.

If the hardness of the processed material is very high, even the wear resistance of the ultra-fine powder mill with high wear resistance will not be low. At this time, instead of replacing the entire equipment, you can contact the Shanghai Shibang Superfine Mill manufacturer, based on the ultra-fine The standard model of the mill, purchased with high wear-resistant fittings, is broken into smaller particles as much as possible before the material is fed into the mill.

If the hardness of the material is not high, it will still wear fast. At this time, we must check the raw materials to see if there are hard-to-grind impurities mixed in. Because it can not be ground, it will continue to cycle and grind in the host of the ultrafine grinding machine, which will accelerate the grinding of the components. The rate of depletion must be screened between feeds to remove impurities.

After ensuring the materials, we must devote more efforts to the operation methods. In strict accordance with the instructions for use, we must refuel the ultra-fine mill. We must not run out of oil. After a certain period of operation, we must stop and maintain the machine in time. Timely cleaning and bonding, as long as the equipment is properly maintained and produced under a reasonable working environment, will greatly extend the service life.
