What is a crusher? How many kinds of crushers are there? What are the uses of a crusher? How to choose a crusher manufacturer?
1, the physical properties of materials, such as brittle, viscous, sediment moisture content and maximum feed size; 2, the total production capacity and product requirements according to the gradation of crusher type and production capacity; 3, technical and economic indicators, so as to conform to the quality and quantity requirements, convenient operation, work reliable, but also to maximize cost savings. The main function of all kinds of crushing and grinding machinery for crushing machinery: 1, jaw crusher, cone crusher, roller crusher, based compression; 2, hammer crusher and impact crusher, the impact; 3, wheel mill and roller mill, to extrusion and grinding action; 4, ball mill, rod mill, vibrating mill and jet mill, the grinding and impact. In general, the coarse crushing processing by jaw crusher, cone crusher, crushing processing using cone crusher, hammer crusher, impact crusher, crushing machine used roll crusher, grinding machining by ball mill, vibrating mill, jet mill etc.. But this is not absolute, some machines are suitable for coarse crushing, but also suitable for medium crushing.
The scope of various types of crusher, jaw crusher and cone crusher is suitable for crushing hard rock blocks (compressive strength in 150-250Mpa); gyratory crusher is suitable for crushing hard (compressive strength is more than 100MPA) and medium hardness (compressive strength at about 100MPA) rock blocks. The hammer crusher is suitable for crushing brittle rock of medium hardness (the ultimate compressive strength is below 100MPA); the roller crusher is suitable for crushing medium hardness toughness rock (the ultimate compressive strength is about 70MPA). In actual selection, the following factors should be considered in light of specific circumstances:
A crusher is a device that exerts mechanical force on a solid material, overcomes the cohesive force of the material and breaks it into small pieces. 2. crushing machinery commonly used types are: jaw crusher, cone crusher, gyratory crusher, hammer crusher, roller crusher, and so on. 3. because of the difference of structure and action.
