Get PriceSo first let's talk about the power calculation of the heavy apron feeder(hereinafter referred to as feeder). The calculation method of power is as follows: In fact, the above formula is suitable for calculating the power of the feeder when it is running horizontally. We assume that the feeder is arranged on a slope with an Angle of α.
