Product Description

Electric control device for mine belt conveyor protection

1. PurposeThe electric control device for mine belt conveyor protection (hereinafter referred to as the electric control device) is mainly equipped with explosion-proof and intrinsic safety control console, explosion-proof and intrinsically safe PLC control box and various protection sensors, which are suitable for the environment with gas and coal dust explosion in coal mine. It is used for electrical control, monitoring and comprehensive protection of belt conveyor and other equipment in coal mine. It can also be used for the control device of electrical equipment in the harsh environment of metallurgy, chemical industry, building materials, electric power, transportation, grain and other industries.

2.Characteristics
