How do you calculate jaw crusher capacity? Example capacity calculation of a 10″ x 20″ (250 mm x 500 mm): Pp = 2800 (2.8 SG) e = 0.2 (halfway between dolomite and sandstone) A = 250/1000 x 500/1000. What is the reduction ratio of jaw crusher? Ideally, the reduction ratio of a jaw crusher should be 6-to-1.

Rose and Hill (1967) considered crusher capacity by determining the amount of time and distance a particle takes between two jaw plates. Particles in the A-B zone discharges at the next reverse movement of the jaw. The maximum size of a particle dropping out of the crusher d max is determined by the open size setting (L max).

a) Primary crusher The raw material from mines is processed first in primary crushers. The input of these crushers is relatively wider and the output products are coarser in size. Example Jaw crusher, Gyratory crusher, Impact Crushers, etc. b) Secondary crusher- The crushed rocks from primary crusher are sent to these secondary

Double Roll & Teethed Roll Crusher. Although its brief period of popularity passed some thirty-odd years since, and only a few sets were installed before interest reverted to other types, the high-speed double roll crusher developed by Thomas A. Edison shortly before the end of the last century warrants a place in any discussion-of crushing

The capacity of jaw crushers is a measure of the mass or volume of crushed material produced in unit time of operation. The capacity is primarily a function of: 1. crusher design characteristics such as width and depth of the crushing chamber, 2. open and closed side settings,

Capacity factor of industrial design compressors amounts from 0.6 to 0.8. Difference in theoretical and actual compressor calculations at inlet and outlet may reach a significant value. When indicated in the data sheet theoretical capacity of compressor unit shall be recalculated for capacity at outlet, thus, to decrease the value by 30-40%.

ROLL CRUSHERS • Roll crushers areused for producing additional reductions in the sizes of stone after the output of a quarry has been subjected to one or more stages of prior crushing. • A roll crusher consists of a heavy cast-iron frame equipped with either one or more hard-steel rolls, each mounted on a separate horizontal shaft. 12
