    Here to tell you about domestic conveyor belt inspection measures to prevent tearing and tear

1, from the source to prevent tearing initiative to strengthen the quality control of coal, increasing impurity removal equipment for cleaning, reduce impurities and chunks of coal. With nearly two years to improve the quality of coal, because impurities torn belt has decreased significantly.
2, to strengthen equipment management, improve belt inspections and inspection efforts to prevent the liner and other sharp objects to fall.
3, to improve conveyor structure, by reducing the blanking point gap, increase the buffer fork, fine material before falling bulk materials, to reduce the impact, reduce material speed and reduce the possibility of impurities into the conveyor.
4, the addition of tearing detection device, after tearing occurs when the conveyor belt, in the shortest possible time, detected, an alarm signal and shut down, minimizing tear length and reduce losses. Currently manufacturers, users have developed a number of devices and tear conveyor ripstop detection device, and achieved certain results. But the belt tear is caused by many factors, we can not completely avoid the conveyor belt tear.
Current application of conveyor means and detecting means tear torn mainly detecting means is generally located at the falling feed point, by a sensor and controller. Sensors mounted on the conveyor or chute under the next controller mounted on the machine side or indoors. When debris torn conveyor belt, the conveyor belt through the debris or material extruded sensor, the sensor signal to the controller, the controller sends an alarm signal and shut down. There are many forms of such detection devices, the basic principle is similar. Are: bucket switch. Pull switch. Conductive rubber switch. Such detection device can play better results, especially for Central wider tear trough angle position. But there are also some disadvantages:
First load the conveyor belt tear and heavy tear, transverse shrinkage conveyor belt or conveyor belts without tearing the material point is not falling off the feed point, pull side and other conditions, the detection device can not play a role in tearing;
In addition, the belt surface can not be repaired after damage and other reasons there is malfunction, requiring constant adjustments. Due to the current application of belt tear detection device there are still many deficiencies, some users believe that ineffective, affecting production, no longer used or even removed.
5, the improved belt structure itself. For example: To improve air tightness belt, to prevent core water, rope rust, require manufacturers to strengthen quality control, improve quality.
6, using tear torn conveyor belts and conveyor belts can be detected, the port is currently rarely used, and some mines use. Tear rope belt with a longitudinal reinforcing materials, adding a strip transverse reinforcement as tear layer, the layer structure is divided into two: one is the use of hanging plastic mesh (steel mesh or fiber mesh cloth); Another is the use of horizontal rope (rope or fiber rope). Overlay with high strength, high flexibility, good abrasion rubber (strong plastic cover different uses different levels). The price of the product than ordinary conveyor belt about 20% higher, but the effect is not too large debris, but once one of the lateral wire exposed rust damage on the conveyor belt faster.
7, using conveyor belts can detect torn. Added in the conveyor belt with a closed coil sensor, the detector mounted on the belt conveyor easily tear parts, the detector connected to the controller. Conveyor normal operation, the sensor through the detector, the detector pulsing. When the conveyor belt tear, cut the sensor coil, the sensor through the detector, the detector stops pulsing, the controller accepts, an alarm signal and shut down. At present, the domestic manufacture of conveyor plant is not yet famous overseas plants such as Goodyear conveyor belt can be produced, but the price is much higher than ordinary conveyor system complex and difficult to maintain, domestic users rarely used.
