Manufacturers tend to use rules of thumb to de-rate crusher capacities for the treatment of highly competent ores that display high Bond crushing work indices (CWi). One such rule is the following: de-rate = (16/CWi)^0.5. However, care is required when using this rule as CWi test methods vary and simplistic approaches do not address all of …

A) Stacked Design. This design is intended to operate in open circuit. With fairly constant ore characteristics and where the feed to the fine crushing plant contains less than 15 percent minus 19MM (¾"), screening ahead of Standard can be omitted. The Standard crusher closed side setting in this case is usually between 28MM and 37MM …

For performance efficiencies, proper circuitry should be designed around the crusher cone, says Schultz. Importantly, the circuit should be engineered to provide the crusher cone with choke-fed material, or enough material to keep the crusher full. Having too little feed can cause the crusher to side load, which stresses components.

Crusher should operate with a steady power draw and as close to full rated power as practical, depending the circuit design and the ability to control system. Note: Feed material characteristics such as gradation, bulk density, mois-ture, clay content and crushability have significant impact on crusher capacity. How to operate a HP cone crusher

Freeport's Morenci operation, for example, commis­sioned a 3.0 x 2.0-m Metso HPGR (called the hydraulic rolls crusher, or HRC) in an expansion mill circuit in 2014. The circuit has a single-line capacity of over 60,000 tpd. with the single HRC having 11.4 MW of installed power, and operating in conjunction with twin MP1250 cone crushers to ...

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.

The single-cylinder hydraulic cone crusher has a new crusher structure, optimized laminated crushing cavity type, and a fully intelligent automation control system. In general, it can be widely used in medium crushing, fine crushing, and ultra-fine crushing operations. The working site of the cone crusher in India.

For the 1-in. screen below the roll crusher the capacity has no correction factor and the area needed is 32/2.1 = 15.2 sq ft. To handle the output from a 40 x 24 roll crusher the screen will have to be at least 24 in. wide. Perhaps it will be more effective to use one continuous screen of at least 20.1 + 15.2 = 35.3 sq ft.
