Belt Conveyor is a friction drive conveyor transported materials continuously. Belt conveyor machine comprises the rack, conveyor belt, pulley, rollers, tensioning devices, driving unit and other components. It not only conveys material, but also can cooperate with various industrial equipments to form a rhythmic transport line.

What is the Requirement for Belt Conveyor Restart-up?
When the belt conveyor stops , restart-up belongs to overload start. Thus it requires belt conveyor equipped with a frequency converter in order to overload start.
Here PK Machinerywill summarize the
Belt conveyor in the pick-up for overloading
startup, motor output torque, which every support to overcome below the belt
between the wheel and the roller shaft caused by static friction torque, also
want to overcome the material on the belt tension caused by the downward drag
Materials on the belt tension caused by the downward drag torque is
constant.But the static friction force is much larger than the dynamic
friction, making it in order to overcome the initial startup of the static
friction torque than the normal run-time dynamic friction torque caused by the
The inverter must have the function of the large starting torque at
low speed.Actually in the process of starting, as a result of the belt scale,
each wheel is time order one by one according to the rotation, will not rotate
at the same time.Even if the wheel rolling, because of low speed between roller
and roller shaft lubrication is not good, will be very acerbity, the dynamic
friction is unstable, so low starting torque has the certain fluctuation.
So this kind of big starting torque at low
speed is the need to maintain a certain period of time, usually at least a few
seconds.The length of the belt and the minimum speed startup, and scalability
of the belt.Because of the low speed, and startup torque and speed fluctuation
will be big. Further more information, welcome to contact us: www.pkmachinery.com
