The bag dust collector of the dry mortar production line and the bag dust collector of the dry mortar equipment adopt a system solution of local closed centralized treatment, and use a high-efficiency pulse jet bag dust collector to collect and reuse the dust generated during the production of the dry mortar production line. The main dust-producing points of the dry mortar production line are: mixers, raw material storage silos, conveyors, packaging machines, etc. Dust collector on the top of the large raw material storage tank: The dry mortar production line is used to store bulk raw materials, such as cement, fly ash, sand, rubber powder, additives, etc. Dust will be generated when pneumatic conveying is used. The use of a silo top dust collector can effectively control the dust coming out of the tank.
