These are primary stage crushers, commonly followed with Centerfeed Mills or other types of secondary stage crushers. The HammerMaster is also a secondary stage crusher in that the maximum feed size is 6" (150mm). The hammers used in the HammerMaster line of mills all weigh 60 lbs (27kgs), which creates a sufficient force to fracture a 6" stone and remain extended from the rotor. The ...

The primary coal crushers may be of different types such as: (1) coal jaw, (2) coal hammer, and (3) ring granulator. Secondary coal crusher: Used when the coal coming from the supplier is large enough to be handled by a single crusher. The primary crusher converts the feed size to one that is acceptable to the secondary crusher.
· This one involves both SECONDARY and TERTIARY crushing. This circuit is employed where either the tonnage or the work index of the ore is high enough to require that the crushing be done in stages. Again the ore will come from a Primary crusher and be scalped. The coarse material will be crushed by the secondary crusher.
Electric motors will only draw as much power as the crusher needs. However, the theoretical difference in a 500,000ton quarry or mine is about 90,000 kW/hours. That reflects only the primary crusher, not the added power it takes downstream to also recirculate 30% more rock through the secondary circuit.
The difference between the volume displaced by the crushing head when it is fully closed and fully open is called the displacement volume. A large displacement volume results in greater capacity because: More material is crushed with each crushing cycle More space is left open as the crushing head recedes, allowing more material to be fed to the crusher at each cycle to fill the larger void ...
In general, a rock crushing plant will have a primary crusher, primary screen, secondary crusher(s) and secondary screen(s), and associated conveyors and stockpiles. It may also involve portable generators powered by diesel engines. Emissions of each pollutant must be less than 100 TPY for the facility to be a minor source.
