DESIGN OF MECHANICAL CRUSHING MACHINE. 2016-4-23 · This crusher works on the simple mechanism called crank and slotted lever mechanism. When the motor is excited using a power source (i.e.3-phase power supply in this case) the shaft starts to rotate which in turn rotates the pulley which is connected to the motor by means of a belt drive.

Different from the wood crusher driven by diesel engines, the electric wood crusher is mainly driven by electricity. And the electric motor power of different types and different output electric wood crushers are also different. The larger the power, the higher the productivity, and the greater the power consumption. So, how do we calculate the power consumption of electric wood shredders?

% EFF is motor efficiency per motor nameplate. Power factor is the ratio of true power (kW) to apparent power (kVA). In the absence of power factor measurement tools, a rule of thumb is to estimate power factor at 0.85. 1.73 is a constant used when calculating three-phase power. 746 is the constant for converting watts to horsepower (746 watts

Torque is nothing but a momentary force developed at the time of force is applied to the motor. The unit of torque is N.m (Newton-meter). In other words, Torque T (N.m) is equal to the ratio between the electrical power P (W) in watts to the acceleration. The total power rating of the motor details can be found from the motor’s nameplate details.
