Quarry crusher big crushing ratio, uniform end product size, simple structure, reliable operation, easy maintenance, economic operation, etc. Crusher machine function processing materials under 100 ~ 500 mm length, its compressive strength up to 350 million mpa, big crushing ratio, material after broken cube grains, etc; quarry crusher series, is suitable for crushing hard materials, such as cement limestone crushing, has great capacity of production, discharge the advantages of small particle size. Crushing methods of quarry crusher : 1, crushed With two broken face approached the extrusion pressure, make the material crushing.Jaw crusher machine, roll crusher machine, cone crusher machine are crushed way of broken machinery; 2, split pieces is the use of teeth wedge material splitting force for broken, focus on the action of forces, adapted to the brittle material crushing; 3, broken material in crushing coal face as under concentrated load between two fulcrum (or are) beam, make the material itself to fold the flexor broken. Quarry crusher general processing relatively large pieces of material, product granularity coarser, usually greater than 8 mm.A certain gap between its structure characteristics is broken, do not contact with each other. Can be divided into the primary crusher, quarry crusher and fine crusher machine. In general by the grinding machine processing of materials is fine, the product particle size is fine, can reach 0.More than 074 mm, and even more.The characteristics of the structure are broken parts (or medium) contact each other, medium is adopted by the steel ball, steel rods, gravel or ore block, etc. But some mechanical crushing and grinding effect concurrently at the same time, such as autogenous grinding machine. |
