Rotary Sand Dryer

Longzhen Rotary Sand Dryer  Advantages:
1. The machine has rational design of spreading materials plate distribution and angle, which has reliable performance, so it has the characters of high thermal utilization ratio, dry and even, litte times of cleaning materials, convenient maintenance and the like;
2. The equipment adopts self-aligning type of tug structure, the tug cooperates well with rolling ring, which decreases greatly the abrasion and power consumption;
3. Specially designed block wheel structure of this machine decreases greatly the horizonal thrust that is produced by working obliquely. Resistance to overload ability is strong, cylinder runs stably, it has high reliability;
4. Dryer has the character of thermostability, it can dry materials by using high temperature and hot air. It has strong extensive ability, when designing it takes production allowance into consideration, even productivity is increased by little extent, it is unnecessary to renew equipment;
5. Cylinder dryer has big handling ability, investment is little and drying cost is low;

Longzhen Rotary Sand Dryer  Introduction:
The Rotary dryer made by out company is mainly used in building materials, metallurgy, chemical plant, cement plant for drying of limestone slag, coal powder, slag, claystone. This dryer is formed by rotary body, lifting blade, driving deviece, supporting device and sealing ring. The dryer has advantages of reasonable structure, high efficiency, low energy consumption and being convenient for transportion.

Longzhen Rotary Sand Dryer  Working Principle:
Rotary drier consists of gyrorotor, spreading materials plate, transmission device, back-up unit, seal ring and the like. Dried materials are sent hopper by belt conveyor or bucket elevator, then pass through feeding machine of hopper and charging pipe into feeding end. Inclination of charging pipe is bigger than materials' angle of crater, so that materials can flow into dryer smoothly. Cylinder of drier is rotating cylinder which forms slight slope with horizonal level. Materials are added from relatively higher end, heat-carrying agent enters from low end, it has counter-current contact with materials, heat-carrying agent and materials form cocurrent flow and enter into cylinder. It move the relative bottom end along with cylinder's rotating materials by gravity. In the process of moving forward wet materials in the cylinder get heat from heat-carrying agent directly or indirectly, which dries the wet materials, and are discharged at the discharging opening through belt conveyor or screw conveyor.
