Optimization of particle size distribution in

15.06.2019  The reasonable rolls gap and teeth length should be 75 mm and 23 mm, respectively. Further, a physical model of a two-toothed roll crusher was established to obtain the optimized roll diameter; it was later found to be >660 mm.

Double Roll Crusher - Osborn

The Double Roll Crusher is generally regarded as a 4:1 feed to product ratio crusher, however in some instances, dependent upon material friability and hardness, it is possible to achieve a 6:1 crushing ratio. The feed material should enter the centre of the gap between the two rolls and spread across the full roll width for maximum efficiency and this

Roll Crusher Manufacturer Design Williams

A combination of impact, shear, and compression are the forces necessary to perform the crushing and size reduction in a Williams roll crusher. The material enters the roll crusher machine and is impacted by the roll as it rotates. Then, as the material is pulled between a crushing plate or rolls, shear and compression forces act upon the material.

Modeling of coal breakage in a double-roll

To represent the particle behaviors and to predict the product size distributions of coal breakage products by a double-roll crusher, a new combined breakage–agglomeration model has been constructed. The model utilizes a fair combination of individual models for two distinct phenomena, the breakage and the agglomeration which occur simultaneously in the double-roll crusher process. Thus, it is capable of representing the complicated reduction and growth in the particle size
