Too large of an angle causes boiling in the crushing chamber. This is where the jaw plates cannot grip onto the rock, and it keeps slipping up and down, avoiding being crushed. The nip angle gets flatter as the machine is set tighter. The settings on a jaw crusherCrushing Efficiency Factors,Toward the foregoing goal, engineers investigated the energy efficiency of crushing for less than ideal cases. In the first experiment they studied the effect of factors such as using a deep bed of particles, a situation usually present in a ball mill. The same type of slow crushing experiment described above was performed, but with a bed five or six particles deep instead of a singleCrushing of coal and calculation of size reduction efficiency.,2015-02-25· Roll Crusher • The reduction ratio and efficiency of roll crusher is very low. • The main advantage associated with roll crushers is small proportion of fines produced and more uniform size of product crushed, than the other crushers. • Low capacity • Low reduction ratio = F/P • Sensitive to top size 2/25/2015 6:58:05 AM 38 39.how how to calculate crusher efficiency,Crusher Efficiency Calculations.

The friction coefficient between steel and particles was 0.25, if the rolls were set at 6.3 mm and both revolved to crush, estimate the diameter of the rolls. Solution Step 1. Estimate the nip angle using Equation (6.3) Substituting friction coefficient μ = 0.25, tan θ = 0.25 or θ = 14.03° Step 2,Dual roll crushers, how they function,Roll crushers will only crush material down to a minimum particle size of about 10 Mesh (2 mm). A roll crusher crushes using compression, with two rolls rotating about a shaft, towards the gap between the rolls. The gap between the rolls is set to the size of product desired, with the realization that the largest feed particle can only be 4 times the gap dimension.

Roll crushersCrushers - QueensMineDesignWiki,For underground crushing, three stages of material handling are defined: pre-crushing, crushing, and post-crushing. The pre-crushing stage prepares the material for the crusher. A grizzly will prevent oversize material from entering the crusher. A rock breaker reduces the size of this material to manageable sizes. The crushing stage further reduces the size of thePrimary Crusher - an overview | ScienceDirect Topics,6.2.3 Roll crusher circuit design. Roll crushers are generally not used as primary crushers for hard ores. Even for softer ores, such as chalcocite and chalcopyrite, they have been used as secondary crushers.
