News Center How to calculate the motor power of rock crusher?
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 = 0.150.2 ; mediumsized machine k0 = 0.15 ; minicomputer k0 = 0.1 .
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 1.32.2kW ¡¤ 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.
