Crawler conveyor is a kind of caterpillar fully mobile conveyor, as a mobile crushing station and sieve substation, due to the limitation of transportation, do not allow it to increase to expand the size and the on-board conveyor length in response to increasing production, crawler conveyor can meet this requirement, it can provide a larger reserve capacity, can through the processing equipment materials transfer at the same time, improve the mobility of the crushing station.

Conveyor capacity is determined by the belt speed, width and the angle of the belt - and can be expressed as. Q = ρ A v (1) where . Q = conveyor capacity (kg/s, lb/s) ρ = density of transported material (kg/m 3, lb/ft 3) A = cross-sectional area of the bu

The torque doesn't have anything to do with accelerating the motor, it's much more about accelerating the load. How fast is your belt moving? You say you have 6000 lb — presumably that's the total load on the 20 feet of belt at any given time.

The Full Load Speed and Torque and is reached when 100% Speed is reached. Note that if the conveyor tries to run at speeds above the Full load speed of the motor, the available torque from the drive drops off rapidly, and the Conveyor load will then tend
