Roll Crusher can Improve the Yield of Mill
As we all know, the roller crusher (roller crusher | | double roll crusher) ,which is suitable for crushing medium hardness materials in the cement, chemical, electric power, metallurgy, building materials, refractories and other industrial sectors, such as limestone,slag, coke, coal and other materials in the debris, crushing operations. The series of roll crusher is mainly composed by the roller, the roller supports the bearing, clamps , adjusts means , the drive means and other components.
Mudanjiang New Materials Technology Co., Ltd first imported FCB West 3.8 m horizontal roller machine from France Fives Lille Group for the grinding of cement clinker. The principle of this machine is the layer crushing principle.When working, one roller rotates, another roller follows, high pressure is applied by the hydraulic cylinder roller at both ends. The broken material is sent into the roll-to-roll once again by conducting device,the repeatedly crushed material is discharged by the discharge opening. The main technical performances of the equipment are as follows: the roll diameter is 182 m, roll width is l.36 m. Motor power is 400 kW. The feeding capacity is l40t / h, the of back powder amount is 620 t / h. In May 1993, this equipment was carried out the production debugging, so that the energy consumption of the production of cement reduced from 45 kW.h / t to 23.5 kW.h / f.
Northeastern University together developed Shenyang Mining Machinery Factory φ1000 mm × 630 mm roll crusher, which was put into use in the bar moshan Tangshan Iron and Steel Group Mining Company iron ore concentrator for the f = 16 iron ore crushing, the feed particle size is -40 ,the discharging size is-5 mm ,the processing capacity of machine was improved 50% - 60%, the processing capacity is 80 to 100t / h. The improved capability is 30% to 50%, the saving energy consumption is 15%, steel ball consumption is reduced by 30%. Maanshan Iron and Steel Group Gushan Mining Co., Ltd developed GMIOOO mm × 200 mm roll crusher, crushing, to = 16-18's iron ore,and then test, come into use since June 2003 , feed size is - 12,the discharging size is -5 mm ,which accounted for 87.8%, which making the processing ability improved from 32 t / h to 40t / h. And reduced the energy consumption of the grinding ball mill .the production practices has proved that the machine handling capacity was improved, the product size is smaller than before, the energy efficient utilization is high, the mill output was improved,the grinding energy consumption and steel consumption were reduced.
