Quartz sand is made through breaking the quartz stone. It's a kind of silicate minerals of stiff hardness, high wear-resistance, stable chemical properties. It is an important industrial mineral raw material, widely used in glass, casting, ceramics, refractory materials, ferrosilicon melting, metallurgical flux, metallurgy, construction, chemical, plastic, rubber, abrasives and other fields.
For quartz sand drying, choosing which kind of dryer is very important besides keeping quartz sand purity and white degree. Among industrial dryers, there are many types such as single-drum, double-drum, three-drum, rotary, indirect heat transfer, etc. The rotary dryer can be used to dry materials rapidly, with compact structure and adjustable rotating speed. Rotary dryer has achieved automation, productivity, serialization, etc., suitable for standard quartz sand processing and drying.
Rotary dryer can be designed according to users' requirements for gas generator, combustion chamber, elevator, belt conveyor, fixed-weight feeder, dust collector, induced draft fan, etc.
Its main part is composed of cylinder, front roller ring, rear roller ring, gear, gear roller, carrier roller, pinion, discharging port, lifter plate, reducer, motor, heat duct, feeding chute and furnace.
1. High mechanization degree, large production capacity, capable of continuous running.
2. Excellent and simple structure, easy operation, smooth resistance to materials getting through the cylinder.
3. Less failures, low maintenance cost, low power consumption.
4. 4. Wide application scope, uniform drying.
