The Selection Criteria of Crusher

 Mining crusher refers to the crushing machinery whose content is  more than 50% of the total content, the row compound particle size is greater than three millimeters. It is invented by British Hengan.  according to the feeding and nesting size size crushing operations are often divided into coarse crushing ,medium crushing and crushing. The commonly used equipments are impact crusher, compound crusher, single stage hammer crusher, vertical crusher, gyratory crusher, roll crusher machines, double roll crusher, combo crusher, and so on.

Machine automatic control, especially the underflow density computer control, which is promoted soon. The thickener underflow computer control, concentration increased to more than 30%. System underflow density and overflow turbidity and correspondingly adjust the the flocculant amount of the control program and the results are quite advanced. In the self-control of the mill, electricity consumption control from the mill to the ore the optimal operation of the computer to adjust the state to eliminate the phenomenon of the the empty mill and bloating, stability, since the operation of the mill production, so that the increase in production from Mill %, and save a lot of electricity.

Crusher can be used to crush the materials of different hardness is a continuous operation, high efficiency crushing equipment is widely used in mining enterprises. The spring-loaded cone crusher is composed by the inner cone, outer cone and dynamic part of the eccentric sleeve is installed on the spindle drive moving cone pendulum movement to do spin, the moving cone liner sometimes near sometimes leaving the fixed cone lining, making the material in the cavity constantly being squeezed and bending, resulting in crushing.

Automation system includes six sub-systems, raw materials screening and conveying control subsystem, ore transport and dry separation control subsystem, furnace roasting control subsystem, high intensity magnetic separation do not control subsystem, weak magnetic separation do not control subsystem, concentration and dewatering control subsystem. 525 sets of production equipment, the whole plant start, stop, interlock protection, hopper blockage and motor overload the fault alarm logic control. Raw material screening and transport control subsystem. Set automatic start and stop equipment, raw materials a secondary screening automatically block ore and fines on the material, as well as automatic outside unloading waste rock material level of the ore bin. Ore transport and dry separation control subsystem. Small shaft furnace and back to mine shaft furnace automatic cloth and weak magnetic ore bin 4 cylinder automatic fabric. Furnace roasting control subsystem. Plus tropical temperature of 22 sets of 100m3 roasting shaft furnace, the combustion chamber temperature , reduction zone temperature.
