However, there is a limit as to what the reduction ratio for a single unit can be, and crushing is done in stages with common size reductions Low reduction ratios and high wear rates are the two characteristics most commonly associated with conventional roll crushers. Because of this, roll crushers are Comminution in a non-cylindrical roll crusher ScienceDirect

Nilai Reduction ratio akan berpengaruh terhadap kapasitas produksi dan juga berpengaruh terhadap energi produksi. Pada operasi crushing, rediction ratio biasanya berkisar antara 2-9. Untuk pengecilan ukuran yang menggunakan Jaw crusher atau cone crusher akan lebih efisien jika menerapkan reduction ratio sekitar 7.Size reduction by crushing has a size limitation for the final products. If we require further reduction, say below 5-20 mm, we have to use the processes of grinding.SIZE REDUCTION BY GRINDING METHODS By

A Constitutive Model for Cyclic Loading Response of
Grain crushing significantly impacts the engineering behavior of crushable sand primarily found in coastal and offshore locations. In the present study, such sand’s breakage characteristics under cyclic loading are addressed by enhancing a well-known sand anisotropic model (SANISAND). The novel features of the current work are to In this case the crushing coefficient is defined as the energy corresponding to a given reduction ratio, and so corresponds to WR above. In order to obtain such a “crushing coefficient”, Carey and Stairmand made use of the similarity in frequency distributions of crushed products and so developed the principle of “associated energy”.Comminution 911 Metallurgist

Size Reduction-1: Grinding Unit Operations in Food
In case of coarse crushing the size reduction ratios is below 8:1 and in fine grinding it is more than 100:1. The limiting size Dp,max of particles that can be caught by the rolls depends on the coefficient of friction between the material and the roll surface, but in most cases it can be estimated from the following relation:
