Structures And Working Principles of Sand Dryer

The sand machine again called sand dryer, hereinafter referred to as the drum dryer, is like with the amount of fabric of rotary dryer. The sand machine because reliable operation, operating flexibility and adaptability, large quantity, key in building material, metallurgy, food, chemical, coal, medicine in the mining niche.

Dry sand, drum dryer drying excellent results. Drum dryer his advantage wonderful capacity of production, widely used; flow resistance small, operation allowed on the fluctuation range is very large, convenient operation, many others. Often used for drying sand, kuangfen, cinders, other folks.

Second, the sand machine structure and principle

1, structure: sand the dryer mainly by:

1, barrel; 2, the front roll ring; After 3, roll ring; 4, gear; 5, block roller; 6, drag roller; 7, small gear; 8, discharging part; 9;Yang board; 10, deceleration machine; 11, motor; 12, hot air way, 13, feeding chute; 14, furnace components, another can depend on user demand design producer gas generator, the combustion chamber or supporting hoist, belt conveyor, quantitative feeder, dust cyclone, induced draft fan, etc.

2, sand the dryer working principle:

Sand by belt conveyor or dou type hoist to hopper, then by hopper of feeding machine through charging pipe in the feeding. Feeding the rake of pipe must be greater than the natural inclination of material, so your material into dry containers successfully. Dryer cylinder can be a horizontal and slightly into tilt of the rotating cylinder. Material from high end to join, the heat from the low end into the body, and the material into counter-current contact, also have heat body and material together and flow into the cylinder body. With the rotation of the drum materials by gravity to a run on the bottom of the end. Wet materials in the cylinder body in the associated with moving forward, directly or indirectly got the heat of the body heat, make wet materials to dry, and then in the material end the machine or screw conveyor belt is sent out.
