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 main component

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.
Rotary Dryer Heating resource
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.

SMAT Dryer advantages
With 33 years of experience in ball mill manufacturing, SMAT always provide you cost efficient but high performance ball mill grinding solutions.
- SMAT rotary dryer adopts the “self-aligning supporting wheel device”, so that the cooperation between the supporting roller and girth gear is always in linear contact, thus greatly reducing wear and power loss, reducing resistance and saving fuel consumption;
- SMAT rotary dryer realizes “zero horizontal thrust”, which greatly reduces the wear of the retaining rollers, and the cylinder runs smoothly and reliably with little vibration and noise;
- The operating parameters can be changed according to different material properties, using different combination lifting plates, so that the material can form a stable full-cut fabric curtain in the dryer cylinder, and the heat exchange is more sufficient.

- 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.

Q:How much fuel is consumed per hour?
The fuel consumption is calculated based on the project condition, that is to say, the fuel consumption is depends on hourly processing capacity, input and output moisture. SMATengineer team is pleased to provide you detailed calculation so that you can decide which fuel is best for you.
Q:Is electricity suitable for the dryer heating ?
Due to electricity has low heating value, it’s not cost efficient to use electricity to heat the dryer.
