(1) Hammer mill is mainly composed of feeding part, crushing chamber and air supply system. The structural components are mainly composed of hopper, upper machine body, lower machine body, machine base, rotor, screen and so on. When working, the material enters the crushing chamber through the inlet and is crushed by the high-speed hammer. At the same time, the crushed object also obtained a high speed, and the upper toothed plate that directly hit the wall of the crushing chamber was crushed again and reflected back, and the reflected material was crushed several times by the hammer at high speed. Under the action of the fan, particles and powder smaller than the sieve holes are quickly screened and sent to the cyclone separator or settling chamber along the pipeline. Hammer mill has the advantages of simple structure, strong adaptability, high productivity and safe use. It can crush cake with high oil content, chaff and straw with high fiber content, plastic material with high protein content and grain with high moisture content, and can be used for various purposes.
Vertical pulverizer also belongs to hammer pulverizer, but it has three major breakthroughs: (1) it does not need to be equipped with air suction system; Output increased by 30%; Change the screen quickly. Characterized in that an automatic feeder with triple functions of iron removal, stone removal and automatic feeding adjustment is adopted; The material distributing device sends the materials into the feed inlet evenly and dispersedly, and the crushing process is even and easy; The rotor is equipped with guide vanes to improve the crushing efficiency and reduce the temperature of the crushing chamber; The special hammerhead arrangement makes the blades of all hammers participate in crushing, which prolongs the service life; 360 full circumference discharge, large screening area, greatly reducing the residence time of broken materials in the crushing chamber and reducing power consumption; The access door is convenient and reasonable, and the embedded rubber strip is sealed and fixed without leakage; Quick screen changing system, automatic screen frame lifting; There is no need for an air suction system, which not only solves the problem of low crushing efficiency caused by the failure of the air suction system, but also reduces the water loss of the crushed materials.
(2) The roller mill is also called the roller mill. Its main working parts are a pair of cylindrical grinding rollers that rotate relatively at different speeds, and the material is crushed by sawing and grinding between the two rollers. The degree of crushing can be adjusted according to needs. Double-roller pulverizer has the advantages of high production efficiency, low power consumption, convenient adjustment and low material temperature rise during processing, and is mainly used in wheat milling industry. In feed mills, it is mostly used in the first process of secondary crushing.
(3) Claw mill is also called high-speed mill. Claw crusher is mainly composed of shell, feed pipe, fixed toothed disc, gate, feed hopper, annular screen, toothed claw, movable toothed disc, pulley, bearing, spindle, powder outlet pipe and motor. This crusher is mainly used to crush various cereals such as corn, soybean and sorghum, and can also process various feeds such as bean cakes, sweet potato vines, peanut vines and peanut skins, and can also crush various raw materials such as fresh sweet potatoes, fresh fruits and peanuts. Its characteristics are high working speed, fine product granularity, wide adaptability to processed materials, small size and light weight, but high power consumption and high noise. In feed processing industry, it is often used as the secondary crushing in the secondary crushing process, or as a multi-purpose crushing auxiliary machine in small processing workshops.
(4) Special pulverizer refers to a pulverizer that pulverizes special materials, or meets special technological requirements, or has a special structure or pulverizing principle, such as a shell pulverizer, an ultrafine pulverizer, a mineral salt pulverizer or a screenless pulverizer.
