How to calculate the power consumption of electric wood

Calculation method of power consumption of electric wood crusher. The calculation method of the actual power consumption of the wood shredder is: data measured with an ammeter x three-phase voltage = actual power. Actual power x power factor = useful power. Useful power x power factor = shaft power. Shaft power/active power=power.

Crusher Efficiency Calculations

Sep 15, 2014 The 1-in. screen is a second deck for the 38 tph from the jaw crusher, so the deck correction factor is 0.90 and that screen capacity is 2.1 x 0.9 = 1.89 tph/sq ft. The screen area needed under the jaw crusher is 38/1.89 = 20.1 sq 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)

Design Fabrication and Testing of a Double Roll Crusher

2.1.9 Crushing Power The required crushing power is a function of Bond work index, capacity and the reduction ratio. Adopting Gupta and Yan [5] the power is given by, P = Q.R d.w i where Q = crushing capacity, Rd = reduction ratio (x 1 /x 2) and wi = work index. In this work Q = .356 t/hr and x 1 = 7.5mm. A roll gap of 5mm had already
