The double-roll crusher model, first proposed by Austin et al. [15] and lately refined by Austin et al. [16], is based on the following assumptions: a) breakage of each size particle occurs independently of the other sizes, …

Double Roll Crusher Power Calculation. Posted on 22. Apr. 2010 - 06:37 Hi, I'm a employ and need to design a double roll crusher that can be used for crushing coal from 200mm down to 75 mm at a rate of 160 tons per hour (tph). Where can I find the mechanical properties of coal and how do I determine the roll diameter, roll speed, torque and ...

 — The double-roll crusher is mainly suitable for coarse and intermediate crushing of brittle bulk materials in mining, metallurgy, chemical industry, coal mine and other industries. Especially in the coal industry, when using this machine to crush raw coal, it can be directly crushed as long as it has undergone iron removal, impurity removal, …
