The crusher is also often used as a plastic auxiliary machine like the chiller
, and the crusher generally handles large pieces of material, and the product size is relatively coarse, usually larger than 7 to 8 mm. Its structural feature is that there is a certain gap between the broken pieces and they do not contact each other. The crusher can be divided into coarse crusher, medium crusher and fine crusher. Generally speaking, the materials processed by the mill are relatively fine, and the product size is fine, up to 0.075 mm, and even finer. Its structural feature is that the broken parts (or media) are in contact with each other. The media used are steel balls, steel rods, gravel or ore blocks. But some machines have both ore crushing and grinding functions, such as self-grinding machines. 上限 5.5 × 1.8m self-mill mill can handle ore size up to 350 ～ 400mm, and the product fineness can reach -200 mesh, accounting for about 40%. According to the crushing method and the structural characteristics of the machine, it is divided into six categories.
I. Impact crusher. The ore block is crushed by the impact of fast-moving moving parts. This category can be divided into: hammer crusher; cage crusher; impact crusher.
Second, the grinder. The ore is crushed in the rotating cylinder by the impact and grinding action of the grinding medium (steel ball, steel rod, gravel or ore block).
Third, other types of crushing mills. A roller mill: crush the material by rotating rollers. B. Disc mill: Use the vertical or horizontal axis of the disc as the crushing part. C. Centrifugal mill. Use high-speed rotating parts and media to generate centrifugal force to complete the crushing action.
Fourth, jaw crusher (Tiger mouth). The crushing effect is that the movable jaw plate is periodically pressed against the fixed jaw plate, and the ore block sandwiched therein is crushed.
Five, cone crusher. The ore block is located between the inner and outer cones, the outer cone is fixed, and the inner cone swings eccentrically, crushing or breaking the ore block sandwiched therein.
6. Roller crusher. The ore block is mainly crushed continuously in the gap between two rotating rollers facing each other, but it also has abrasion and peeling effects.
Of course, it is necessary to emphasize here that the crushers produced by Dongguan Guansheng Machinery Co., Ltd. are mainly plastic crushers, that is, they are widely used in the plastics industry. In terms of function and performance, they are still similar to the various types of crushers mentioned above. Big difference!
