LMC (CDMC) type long bag dust collector is a low pressure pulse bag dust collector, basing on the jet pulse dust collector technology, developed for high wind volume fume cleaning. It has the features of reversed blowing bag dust collectors, such as strong deashing capacity, high filtering efficiency, and low discharging concentration, and it has the features of the stably operation, low gas consumption and small stand area, and it is very suitable to process high wind volume fume. LMC (CDMC) type low pressure long bag pulse dust collector has been widely used in the world, in the fields of cement, metallurgy, petroleum, building, food, machine, carbon black, electric power, refuse burning, industrial stoves, for high temperature fume cleaning and powder material recycling.
