During the working process of the belt conveyor, the longitudinal tear of the conveyor belt is caused by the large foreign objects such as sharp-cornered gangue, coal lumps, long iron and other sharp-edged objects falling on the conveyor belt, causing the longitudinal tear of the conveyor belt, and the tear part is mainly in the feeding. In particular, the steel rope core conveyor belt has weak transverse strength between the core steel ropes and is easy to tear, so it must be protected and tested. The longitudinal tear of the conveyor belt will not only cause the loss of the conveying equipment, but also seriously affect the production. At present, the main solution is to install a longitudinal tear protection device at the feeding point.
The longitudinal tear protection device is composed of tear-proof sensor and control box. One control box can be used with 4-6 sensors. The sensors are usually fixed between the buffer rollers under the conveyor belt of the receiving section of the belt conveyor. , the control box is set up on a non-vibration wall nearby.
