4.ROLL CRUSHER Roll crushers are used 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. Roll crushers have a theoretical MAXIMUM reduction ratio of 4:1. If a 2 inch particle is fed to the roll crusher the absolute smallest size one could …

Reduction ratio - 10:1. Impact Crushers can be used for either primary or secondary crushing and work by creating a sudden impact force that shatters the material into smaller pieces. They often come as primary crushers (with an 8:1 crushing reduction ratio) or secondary crushers (10:1 reduction ratios) and are perfect for crushing medium-hard ...

Cones can vary from 60 percent to over 80 percent efficiency. Crusher efficiency has a huge influence on productivity. As an example, let's compare two cones with 300 tph capacity, one at 60 percent efficient and the other at 80 percent efficient. 1) 300 tph x .6, (60%eff.) = 180 tph of finished product with the cone at full capacity ...

The distance between rolls is calculated to be 3m. Next, determine the specific gravity of the ore. This is 2.75 tons per cubic meter. Finally, calculate the roll crusher capacity using the formula above: C = V*L*D*S*60. C = 50*2*3*2.75*60. C = 49,500 tons per hour. Enter the linear speed of material, width of the rolls, distance between rolls ...

An efficiency of 99% will equate to a significant loss of capacity. Efficiency is the ratio of undersize material in the feed that actually passes from the media to the undersize material that should pass from the media. This ratio is desired to be , however this is not possible due to the factors affecting the process.
