The design processing capacity of the project is 50 tons/day, and if it is operated at full capacity, it can be completed in 4 hours.
Operation profile
The whole set of processing equipment is configured for vehicle incoming material one-time feeding, automatic push, crushing line. The whole set of equipment adopts modular production and assembly to ensure that each link can be disassembled separately for easy maintenance.
The feeding part of the equipment is completely sealed and separated from the back end, and negative pressure is formed to ensure that the odor gas generated during the feeding process will not drift out, and then discharged after entering the gas deodorization system through the pipeline. The overall sealing of the equipment is high, which avoids dripping and seepage during use; Eliminate dirty, smelly, to avoid the impact on the lives of surrounding residents.
