There are many classification methods of the crusher, such as according to his crushing principle can be divided into gear type, blade type, hammer type and so on. According to its scope of use, it can be simply divided into production shredders Laboratory shredders Household shredders small shredders and so on. Where is it commonly used? Is it different in any concrete way? Here I give you a brief introduction to some knowledge about the crusher.
1. What is a crusher?
It is a machine that crushes large-sized solid raw materials to the required size.
There are four kinds of external forces applied to the solid in the crushing process: rolling, shearing, impact and grinding. Press rolling is mainly used in coarse and medium crushing, suitable for the crushing of hard materials and large materials; Shearing is mainly used in fine crushing, suitable for the crushing of ductile materials; Impact is mainly used in medium crushing, fine grinding, ultrafine grinding, suitable for crushing brittle materials; Grinding mainly in fine grinding, ultrafine grinding, suitable for small pieces and fine particles grinding.
The actual grinding process is often several external forces acting simultaneously.
2. How is the classification of the crusher divided?
According to the size of the crushed material or crushed material, the crusher can be divided into coarse crusher, medium crusher, fine mill, and ultra-fine mill.
According to the scope of application, the mill can be divided into plastic mill, feed mill, straw mill, sawdust mill, wood chip mill, slime mill, shell mill, Chinese medicine mill and so on.
According to the working principle, the mill can be divided into box mill, air mill, ultrafine mill, frozen mill, low temperature mill, turbo mill, ultra-fine mill and so on.
3. What are the application fields of the crusher?
Large mill is mainly used in metallurgy, building materials, chemical industry, mining, highway construction, water conservancy and hydropower, refractory materials, steel and other industries of mineral products grinding processing. It can process quartz, feldspar, calcite, talc, barite, fluorite, rare earth, marble, ceramics, bauxite, iron ore, copper ore, iron oxide red, Zircon sand, slag, cement clinker, activated carbon, dolomite, granite, garnet, iron oxide yellow, fertilizer, compound fertilizer, fly ash, coal, diamite, chrome oxide green, gold mine, red mud, clay, kaolin, coke, Coal gangue, China clay, kyanite, fluorspar, bentonite, medical stone, shale, basalt, gypsum, graphite, silicon carbide, thermal insulation materials and other MoHs hardness below 9.3, humidity below 6% of all kinds of non-flammable and explosive mineral materials.
The application field of small mill is more extensive, generally refers to the operating power of less than 2 kilowatts, small volume, desktop or mobile mill. Small crusher according to the application of different places of the name is also different laboratory crusher, Chinese medicine crusher, home crusher and so on.
