Double Roll Crushers produce a finer product at lower reduction ratios and capacities. ... These dusttight roll crushers are perfect for crushing ash, limestone, coal, or glass ...
After that, a combined breakageagglomeration model was proposed to represent the particle behaviour and to predict the product size distribution of a doubleroll coal crusher. ...
Double roll crushers (DRC) have the highest throughputs among primary crushers. In the oil sands, the hourly capacity may exceed 14,000 t/h. They are preferably used to comminute mediumhard rock ...
The singleroll crusher has a tip speed of 400450 ft/min while the 6 x 7ft teethed roll crusher has a normal, noload, surfaces speed of just under 3500 ft/min. It can be readily appreciated that this high velocity induces an extremely violent crushing action, in conjunction with the 3 to 4in. knobs which protrude from the roll surfaces.
Userfriendly, highfunctional CrusherSupports a wide variety of crushed particle sizes. Designed to bite objects between the two rolls and crush the objects using a builtin hybrid mechanism that crushes material by compression action and forcedly discharges the crushed product.
