The impact idler is installed under the conveyor receiving section to reduce the impact of the conveyor belt and extend the service life of the conveyor belt.
impact idler life is five times that of traditional roller, corrosion resistance, flame retardant, anti-static, light weight, widely used in mining.
Three aspects to protect the impact idler:
a. Impact idler temperature protection:
When the belt conveyor pulley and belt friction causes its temperature to exceed the limit, the detection device installed closely to the pulley sends an overtemperature signal. After receiving the signal, the receiver, after 3s delay, makes the execution of part of the action, cuts off the motor power supply, the conveyor automatically stops running, and plays the role of temperature protection.
b. Impact idler speed protection:
If the conveyor fails, such as motor burning, mechanical transmission part damage, belt or chain pulled off, belt slip, etc., the magnetic control switch in…
