1. Project overview
In order to adapt to environmental protection policy, from the pre-hanging machine out, the paper mill caustic white mud (or green mud) through the tape, is transported to the white mud drying system after drying, de-dusting into the bulk powder library, bulk shipment to the cement plant or mixing station and other downstream users. Hot blast stoves can use coal-fired boiling stoves or gas (oil) hot blast stoves.
2. Key technology
High efficiency rotary dryer, multi-angle hoisting plate, anti-agglomeration hinge, spiral scraping guide sleeve, anti-stick wall vibration hammer and closed self-cleaning forced feeder, coal burning (gas or biomass three uses) hot blast stove, roller slag cooler at the bottom of boiling furnace.
