Integrated protection device for mining belt conveyor

Integrated protection device for belt conveyor

Product description

It is suitable for the dangerous environment of gas and coal dust explosion. Used for electrical control, monitoring and comprehensive protection of belt conveyor and other equipments in coal mine. Equipped with smoke sensors, temperature sensors, speed sensors, coal level sensors, deviation sensors, tear sensors, wire switches, sprinklers and other products produced by the company. It can realize low speed skidding, strip tearing, coal piling, deviation, smoke, ultra-mild emergency stop, tensioning stop and other protection. And can realize the temperature and smoke protection at the same time to stop the temperature (smoke) automatic sprinkler cooling.
