1-100 tons per hour.
Suitable for Wood Chip, Sawdust, Gypsum, Limestone, Bentonite, Mineral Concentrate, etc.
Rotary dryer, also known as rotary drum dryer, is a kind of drying equipment, which is widely used in mining project, chemical industry and construction project. It is divided into direct heating drum dryer and indirect heating drum dryer.
It is suitable for drying magnetic, heavy, and floating concentrates of metal and non-metallic ores, clay in the cement industry, and coal slime in the coal mining industry and so on.
It is characterized by high productivity and easy operation. The cylinder body of the rotary drum dryer is a horizontal rotary cylinder, which is welded with various lifting plates with staggered arrangement angles from feeding end to discharging end.
Dryer cylinder is the key part of the dryer system. The material and hot air will pass through the cylinder.
Transmission system includes, Motor, Reducer, Coupling, and Pinion.
Feeding and discharging cover will help the dryer to keep inside temperature, thus to save the fuel consumption.
Girth gear is important device to transfer the power from pinion to the dryer body, thus to make the dryer running.
Supporting rollers is the device to hold and support the dryer cylinder.
Popular heating resource for the rotary dryer includes, Natural Gas, Coal, LNG, and Wood. Since each type fuel has different heating value, the hourly consumption is different if user uses different type fuel.
On the other hand, different type of fuel requires different type burner. SMAT can provide full project solution, includes the heating part designing.
By the way, electricity is not ideal resource, as it’s heating value is too low. For 1 Kw, it can give 860 Kcal heating energy only. We do not suggest user use electricity to heat the dryer.
- The newly designed feeding and discharging device makes the dryer run more continuously, which avoids the phenomenon of easy blockage, discontinuity and unevenness of the feeding port of the tumble dryer, and effectively reduces the load of the dust removal system;
- The scientific external insulation of the cylinder reduces heat loss, improves heat utilization and reduces fuel consumption.
