Coal mining Scraper conveyor can be divided into heavy-duty belt conveyors, such as mining stainless steel roller conveyors, and lightweight scraper conveyors used in the food light industry, chemical medicine and other industries. Instruct the coal mining scraper conveyor to operate the material control system, but the coal mining scraper conveyor control system also has certain requirements. If the motor next to the coal mining scraper conveyor is directly overloaded and started, the power supply needs to provide six to seven times more current than during normal operation.
Due to the excessive current of the coal mining scraper conveyor and the long start-up time, the motor will be burned. When the current is too large, the voltage is fast, the roller and the adhesive tape form a slip, forming a conflict, which causes the conveyor belt to wear quickly and affect the service life of the belt. Therefore, under the heavy load of the coal mining scraper conveyor, the torque can be started at low speed, stable, and the dynamic stress can be reduced without charging. If the acceleration of the coal mining scraper conveyor is too large, it will cause the material to fall. When the coal mining scraper conveyor is used in combination, a loader is installed in the front, and an unloader or conveyor belt is installed in the rear.
Or the capacity of the coal mining scraper conveyor is too large. When a heavy load occurs, the motor will be burned. This requires a speed control device. When the load is high, the material can be run quickly. When you are young you may want to run at low speed to complete full load. During the operation of the coal mining scraper conveyor, many obstacles such as configuration obstacles, safety and material particles should be monitored.
Coal mining Scraper conveyor are usually composed of drive roller sets, roller sets, tensioning devices, cleaners, conveyor belts, guide grooves, various protection devices, and key components such as heads, tailstocks, and intermediate frames. The driving device of the coal mining scraper conveyor is mainly divided into a mechanical driving device and a hydraulic driving device. Mechanical drives are used to ensure the safety and reliability of the system. Therefore, the design usually follows the system full-load start-up and long-term operating conditions.
