How to calculate the motor power of rock crusher?

Rock crusher power P (kW) can be calculated as: P = mR2n3jk1/108 �� 103. Wherein m - hammer mass kg; R - rotor radius, M; j - hammer total 126201290523ber;  - mechanical efficiency �� = 0.7-0.85; k1 - correction coefficient. It is associated with the periphery of the rotor speed, the higher the speed, the lower the chance of each hammer blows material.jaw crusher: http://www.jawcrushers.org

The rock crusher empirical formula P (kW): P = 0.15D2Ln. Wherein D, L - rotor diameter and length, m; n - rotor speed, r / min. Where 0.15 is the empirical coefficient. Of control the domestic Crusher accounting results, most cases are relatively close to the actual error is larger special circumstances. For a crusher of the diameter and length is greater than 1.6m , or the length of the rotor is less than 0.4m desirable factor of 0.2 . Therefore, the empirical correction: P = k0D2Ln. Where k0- empirical coefficient, mainframe k0 = 0.15-0.2 ; medium-sized machine k0 = 0.15 ; minicomputer k0 = 0.1 .Cone Crusher: http://www.conecrusher.org

Rock crusher motor power can also be obtained by productivity and material unit energy consumption (specific energy consumption). The broken limestone unit energy consumption of 1.3-2.2kW �� h / t; the broken coal unit energy consumption of 1.4 - 1.9kW �� h / t; crushing coal energy consumption: the rock crusher industry standards unit energy consumption of 1.4 - 1.9kW �� h / t, the German industry standard specifies a 1.2 - 1.9kW �� h / t.Mobile Jaw Crusher Plant: http://www.mobilecrushingstation.com/Mobile-Jaw-Crusher.html
