# double roll crusher design calculation

Design and production of an indigenous roll crusher from locally available materials for low hardness rocks was carried out in this work. The throughput capacity of the machine was 1.43tonnes/hour. The theoretical efficiency of the double roll crusher when crushing limestone was 60% while that of kaolin was 80%

Apr 07, 2010 Apr 22, 2010 Hi, I'm a student and need to design a double roll crusher that can be used for crushing coal from 100 mm down to 50 mm at a rate of 300 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 reaction forces on the shafts if the rolls have teeth? Any references would be appreciated

Double Roll Crushers. Double roll crushers reduce primarily through compression, although some shear is obtained with toothed rolls. Rolls for these crushers come in combinations of smooth, corrugated, and toothed designs. Double Roll Crushers produce a finer product at lower reduction ratios and capacities

Feb 24, 2016 Feb 24, 2016 Although its brief period of popularity passed some thirty-odd years since, and only a few sets were installed before interest reverted to other types, the high-speed double roll crusher developed by Thomas A. Edison shortly before the end of the last century warrants a place in any discussion-of crushing equipment. In 1960, the largest machine of this type the 6 x 7 foot “giant” rolls
