The two-stage pulverizer is improved on the basis of the old hammer crusher. It is a new type of coal gangue pulverizer, which is a special type of coal washing stone and masonry. This model solves the shortcomings of large moisture content of materials. Even if the water content is large, it is easy to be broken and will not cause the problem of machine blockage. Because the two-stage crusher is designed without sieve bottom and screen. Therefore, even if the material moisture point is large, it will not be blocked, even if it is rainy, it can be produced normally. In addition, although the coal pulverizer does not have a sieve bottom, it is pulverized by two upper and lower stages of rotors, and the discharge granularity is more uniform, and the ultrafine shape can be controlled to be less than 2 mm. The use of vermiculite and cinder as materials for brickyards and internal fuels; the use of vermiculite and shale to produce standard bricks and hollow bricks is a major measure in line with national policies and benefiting the society. However, the problem of pulverization of these materials, especially the comminution of wet materials, has always been a problem that plagues the normal production of brick factories. A utility model patent product that can easily smash high-humidity coal gangue, shale, cinder and other materials--two-stage pulverizer is equivalent to two hammers breaking into one, and reasonable combination into one whole, two sets of rotors are used in series.
Operational precautions for two-stage pulverizer
1. Check the power supply, voltage, frequency and connection method before starting the machine to meet the requirements of the motor nameplate. There is a good grounding device.
2. Check that the screws at each connection point are tight.
3. Turn the motor wheel and pulley by hand, whether it is flexible to rotate, if there is friction, timely maintenance.
4. There is abnormal noise when starting up, and should be stopped and checked in time.
5. Add grease once a week to each bearing position.
6. The rotor turns in the direction indicated by the arrow.
