Rose and English 9 determined the capacity of a jaw crusher by considering the time taken and the distance travelled by the particles between the two plates after being subjected to repeat crushing forces between the jaws. Therefore dry particles wedged between level A and level B Figure 4.4 would leave the crusher at the next reverse movement of the jaw.
Oct 21 2020 Capacities in the following tables are based on material weighing 100 lbs. per cubic foot average stone with crusher set to produce 15-20 oversize above ring size with uniform feeding of material and properly sized for entering the jaw opening of the crusher. The average capacity may vary as much as 25 depending on the character of the material being crushed.
For a smooth reciprocating action of the moving jaws heavy flywheels are used in both types of crushers. Blake type jaw crusher may be divided into two types. 11 A SINGLE TOGGLE TYPE In this the number of toggle plate is only one. It is cheaper and has less weight compare to a double toggle type jaw crusher.
