Introduction:
　　　Composite crusher is a kind of no screen 、adjustable fine crushing machine，it is optimal designed on the basis of advanced fine crushing technology both at home and abroad. It is mainly adapted to medium-sized raw materials and clinkers , at the same time can also be used for fine-crush dolomite, coke precious stones, lead-zinc, serpentine, blast furnace slag, coal gangue , phosphate rock materials with medium hardness , especially suitable for hard limestone, dolomite, granite, basalt artificially build sand or highway pavement stone processing.
　　　This crusher has big breaking ratio, discharging size is adjustable , don't suffer from the wear of plate hammer and the plate, it is not easy to plug when crushered high moisture、large mud containing materials; Using elastic and regulatory stucture, the material which can not brken ,they will be automatically discharged, it can’t make the damage to equipment; the bearing is horizontal and with long life, it can break high temperature materials (such as cement clinker); unique rotor structure, when break materials, the rotor body is virtually non-wear; the behind Cavitiy set-up screwrod or hydraulic open structure, do not need main equipment you can easily replace the easywearing parts.
Working principle:
　　　Materials fall into the high-speed rotation impeller from the above of machine, under the action of high-speed centrifugal force, have high-speed impact with another umbrella form materials which flow around the impeller, after they attack each other, then discharged from the bottom, it forms close-circuit and with many times circulation,it can achieve the required product size by screening equipment controlling.
Features:
1.simple structure 、low operation cost. Using the principle of stone strike stone , smaller wear.
2.broken rate is high, energy conservation
3.with fine, coarse grinding function
4.little affected by material moisture content, humidity can reach 8%.
5.working noise is less than 75 db, less dust pollution.
6.suitable for breaking medium hard, especially hard materials.
7.products are cubic, packing density is big, a very small iron pollution
8.little wearing of the impeller , easy maintenance.
