Crusher Efficiency Calculations

15.09.2014  The screen area needed under the jaw crusher is 38/1.89 = 20.1 sq ft. For the 1-in. screen below the roll crusher the capacity has no correction factor and the area needed is 32/2.1 = 15.2 sq ft. To handle the output from a 40 x 24 roll crusher the screen will have to be at least 24 in. wide. Perhaps it will be more effective to use one continuous screen of at least 20.1 + 15.2 = 35.3 sq ft. A 4-ft by 10-ft

Capacities and performance characteristics of jaw crushers

performance of jaw crushers are given in Table 2 (Hersam, 1923). For calculating the values of K2, the value of Kg for materials like granite and traprock were set equal to one, and the values of KI were calculated with Eq. (10). The variation of K2 with T/G (Table 2) can be represented by the equation K2 = 1.92 x 1 o~.~~~~ (11)

These packages evaluate the passage of single 2D particles (normally discs), moving through the crusher cavity. But the simulations are not able to easily predict performance outside of the field tested database, and are limited in their ability to handle complex shapes in the crusher cavity. These empirical models can be used to predict existing crusher performance quite accurately, but ...
