What are the feeding methods of rotary kiln? What are the feeding equipment of rotary kiln?
Common rotary kilns include cement rotary kilns, lime rotary kilns and metallurgical rotary kilns. The materials baked and calcined in rotary kilns have three forms: solid, liquid and slurry (paste). The feeding methods of rotary kilns with different forms of materials are also different. What are the feeding methods of rotary kiln? What are the feeding equipment of rotary kiln?
Xiaobian consulted the rotary kiln engineer of our company, and learned that the rotary kiln is being used more and more widely, not only for the production of cement and lime, metal calcining and shaping, metal metallurgy, but also for the treatment and processing of dangerous materials. Since then, more and more materials can be processed by rotary kiln, including all kinds of solid, liquid (paste) and slurry. The feeding methods and feeding equipment of rotary kiln are also more and more.
Feeding method of rotary kiln
1. Feeding mode of solid material
The solid materials of rotary kiln are block and powder, which can be transported to the hopper and feed port by the feeding equipment of rotary kiln, such as belt conveyor, elevator, belt gauge, storage hopper, two-roll crusher, forklift, double-layer quick flip unloading valve and so on.
2. Feeding mode of liquid material
Liquid material feeding methods of rotary kiln generally include inflow method and injection method, flow method, that is, the use of ladle type feeder slurry into the kiln. In the injection method, the slurry is injected into the kiln by the spray gun under the pressure of 1.176 -- 1.372MPa through the mud pump in series of two stages. In addition, it can also set the ground storage tank, which is provided with a stirring paddle and a motor; Screw pump 2 sets.
3. Feeding mode of slurry material
Slurry or paste material is fed in a similar way to liquid material. Generally, there is an above-ground storage tank in the feeding room, and the paste waste is sent to the primary combustion chamber through the pipe by a single screw pump.
