• Sand drops on a conveyor belt at constant rate | Physics

Jan 09, 2021 A conveyor belt is driven at velocity ##v## by a motor. Sand drops vertically on to the belt at a rate of ##m~kg~s^{-1}##. What is the additional power needed to keep the conveyor belt moving at a steady speed when the sand starts to fall on it?

• homework and exercises - Power of conveyor belt required

Oct 08, 2019 A conveyor belt is driven at velocity v by a motor. Sand drops vertically onto the conveyor belt at a rate of $m$ kg/s. What is the power required to move the belt at a consistent speed? In this case, the rate of change of the kinetic energy of the sand due to its horizontal speed is $\frac{1}{2}mv^2$. Which seems to imply that that is the power that the motor is

• Dynamic transition in conveyor belt driven granular flow

Mar 01, 2015 We consider the flow of disks of diameter d driven by a conveyor belt of dynamic friction coefficient μ through an aperture on a flat barrier. The flow rate presents two distinct regimes. At low belt velocities v the flow rate is proportional to v and to the aperture width A.However, beyond a critical velocity, the flow rate becomes independent of v and

• How to calculate motor drive torque for belt and pulley

Jun 07, 2019 For a belt drive system, the motor torque required during constant velocity is simply the total axial force (F a) on the belt multiplied by the radius (r 1) of the drive pulley.
