Excellent Quality and Good Preformance Sand Rotary Dryer/Silica Sand Rotary Dryer with High Output

Introduction of Silica Sand Rotary Dryer

Rotary dryer is mainly used for the drying of materials like slag, clay and coal dust in building material industry or metallurgy industry, and leaching slag in metal beneficiation. In order to control the temperature of the dryer, a thermocouple which can show the temperature change of the dryer’s feeding and discharging ends is allocated on the feeding and discharging devices. This offers support for the better control of the working temperature (normal 350-380 centigrade) in the drum. Rotary drum dryer is used in the drying of graininess material, and sticky paste material or high moisture material by adding materials. Its advantages: great production capacity, wide rang of application, small flow rate resistance, large fluctuation range in manipulation and convenient operation. It is most used in the drying of sand, mineral powder, coal slurry, chicken manure and dairy manure.

Application of Silica Sand Rotary Dryer

Rotary dryer can dry many kinds of materials which contain moisture, such as coal, coal slurry,

slag, industrial waste, and clay stone. Rotary dryer are widely used in building materials,

metallurgy, and chemical industry. Rotary dryer is handling by bringing it into direct contact

with a heated gas. The dryer is made up of a large, rotating cylindrical tube,the dryer slopes

slightly so that the discharge end is lower than the material feed end in order to convey the

material through the dryer.

Working Principle of Silica Sand Rotary Dryer

The heat source of dryer is from combustion devices. This dryer adopts direct flow heating method. So the material should be sent to the shell by the feed chamber and feed chute. After that the material will be pushed backward by the spiral shoveling plate. As the dryer is located with a tilt, the material flows to the end by the gravity and circumduction meanwhile it is shoveled repeatedly by the shoveling plate to the upper end then comes down constantly, forming an even curtain in the drum and exchanging heat fully with the hot current in the drum. With the material being raised and scattered again and again, the moisture is dried gradually. Finally it is dried totally.

Strcture of Silica Sand Rotary Dryer

Rotary dryer machine is mainly composed of shell, back and forth supporting wheel, feeding and discharging unit and gear cap. The accessories which are not in the the scope of this machine include firebox, feeding and discharging equipment, dust catcher, etc.
