The special equipment for polishing powder for polishing powder of Yumingke MQW series rare earth crushing machine is a physical and chemical indicator for rare earth raw materials. Special crushing equipment developed and developed by targeted development and development. \"The design concept of people -oriented\". After the preliminary formula processing, after the MQW series of rare earth dedicated equipment crushed and classified, rare earth products can be directly launched.
The fluidized bed -type airflow ultra -micro crushing machine is the current leading model, which has gradually developed and improved on the basis of the shortcomings of many airflow crushing equipment. Its advantage is that the fragmentation of the product has a wide range of strength, the particle size is appointed within the range of 3 \u0026 mdash; 74um. The finished product has a turbine ultra -fine grade machine with high grading accuracy, which makes the particle size small and uniform, widely available scope, small mechanical wear, production energy production capacity Low consumption, high degree of automation, good stability performance, compact equipment structure, small area and negative pressure production, no dust pollution, excellent environment, and other advantages.
We should first understand its working principles and performance in front of the airflow crushing machine in the purchase of a fluidized bed -type laboratory.
The working principle of the airflow crusher of the fluidized bed is to compress the air through the frozen, filter, and dryness, and form an ultrasonic airflow into the crushing room by the nozzle to make the material become darling. At the jet air flow of several nozzles, it produces severe collisions, frictions, cutting to achieve the super fine crushing of particles. The crushed materials are transported to the impeller hierarchical zone. Under the action of the grading wheel clutch and the fan of the fan, the separation of coarse and fine powder is separated. The rough powder returns the crushing room according to its own gravity. The airflow enters the whirlwind collector, and the fine dust is collected by the bag dust collector, and the purified gas is discharged by the campaign. The following summarizes some tips for choosing a fluidized bed is the laboratory airflow crusher.
1. Determine the type of crushing machine you want to buy according to the type of crushing raw materials. If it is mainly for crushing grain feed, you can choose the hammer pieces of the top feed; For valley feed, you can choose a claw type crusher; if you are required to be good, you can choose to cut into the feed hammer type crusher; For pre -mixed feed, it is required that the particle size of the product is very fine and can be adjusted as needed. Special sieveless crusher should be selected.
2. Select reasonable productivity. The production capacity of the selection of the fragments should be slightly greater than the actual needs of the actual needs. Avoid the decline in the production capacity of the crusher caused by hammer sheet wear and air duct leakage, which will not affect the continuous production and supply of the feed.
3. Energy saving when choosing is a point, because its power consumption is very large. According to the standards of the relevant departments, the hammer type crusher is used in crushing corn \u0026 phi;When a sieve of sieve holes, the output of each electricity shall not be less than 48 kg. At present, the electricity output of the domestic hammer type pieces has greatly exceeded the above provisions, and the high-quality ones have reached 70-75 kg per kWh.
4. Determine the supporting power. It means that it is not a fixed value but a certain range. For hammer type and sieve holes, the selected supporting power is also different. The larger the sieve holes, the smaller the matching power should be selected. When the hammer -type metal shredder is made of 10.5 times crushing, a small parameter is taken;
5. Fragmers. There are three ways to output crushing finished products: self -weight, negative pressure suction, and mechanical transmission. Small stand -alone machines are mostly used to simplify the structure. Most of the medium-sized crusher has a negative pressure suction device. The advantage is that it can absorb the moisture of the finished product, reducing the humidity in the finished product is conducive to storage, improved the crushing efficiency by 10-15 %, and reduce the dust of the crushed chamber. The institutional delivery is mostly used in a tablet with a desktop output than 2.5T.
6. Dust and noise of the pieces. Dust and noise in feed processing mainly come from crusher. During the selection, you should fully consider these two sanitation indicators. If you have to choose a crushing machine with noise and dust, the dust -proof measures should be adopted to improve the working environment, which is conducive to the health of the operator.
The above is some of the tips for buying the airflow crusher of the fluidized bed laboratory. In the actual use, it should also be adapted according to its own conditions, and it should be used flexibly according to local conditions. In this way, it can save costs to save costs.
