In most size reduction equipment, all three forces are present, but often one is more important than the others.

Theory of Size Reduction Food Tech Notes

2020-7-15  An intermediate and more realistic method of predicting power consumption for crushing and grinding was proposed by Bond in 1952. It states that “the work required to from particles of size is proportional to the square root of the volume ratio (S P /S V ) of the product.

CHBE 344 Unit Operations I Size Reduction and Enlargement 2-3 x Crushing strength: Each material has its own strength with which to resist crushing. This affects the power consumption of the crusher. x Soapiness: In general this is a measure of the coefficient of friction of the material surface. If the coefficient is low,the crushing may be difficult.
