Application of Sawdust dryer
Sawdust dryer can dry high wet and high gravity materials, such as kinds of sand, dry-mixed mortar, cement slag, clay, coal gangue, mixture, fly ash, gypsum, iron powder, limestone, coal, ore, Lan carbon and so on.
Structure characteristics of Sawdust dryer
Sawdust dryer is mainly consist of feeding device, feeding chute, roller, air heating furnace, hot air duct, front roll ring, rear roller ring, block roller, gear, lifting board, automatic cleaning device, reducer, motor, sealing device, discharging device, power distribution cabinet and other components.
Working principle of Sawdust dryer
Sawdust is carried by belt conveyor or bucket elevator to the hopper, and then go through the feeding pipe into the feed end by charger. The feed pipe’s slope should be greater than the natural inclination of materials, so that the materials can flow into the sand dryer smoothly. Sawduat dryer cylinder is a slightly tilted cylinder with the horizontal line. Material is added from high end and heating medium is added from the low end to become countercurrent contact with material. But sometimes they flow into the cylinder together. Materials run to the bottom by gravity with the rotation of cylinder. In this process of moving forward, heating medium give wet material heat directly or indirectly to make them to dry. At the end, the material is sent out by belt conveyor or screw conveyor at the discharger end.
Performance characteristics of Sawdust dryer
The investment is lower 20% than imported products.
The wear-resisting of material is 3-4times than ordinary material.
This device can improve above 40% thermal efficiency than traditional devices.
The moisture can under 0.5%-1%
Rigorous sealing.
It also has good heat preservation system, the temperature of outer barrel is under 60℃, exhaust gas temperature is under 120℃, out-feeding temperature falls below 60℃.
The discharging can be packed directly to reduce the comprehensive energy consumption greatly.
