We are one of the reputed organization that is designing and developing top-notch quality Coal Dryers

The Coal Rotary Dryer is made up of a large, rotating cylindrical tube, usually supported by concrete columns or steel beams. 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 under gravity. Material to be dried enters the dryer, and as the dryer rotates, the material is lifted up by a series of internal fins lining the inner wall of the dryer. When the material gets high enough to roll back off the fins, it falls back down to the bottom of the dryer, passing through the hot gas stream as it falls. This gas stream can either be moving toward the discharge end from the feed end (known as co-current flow), or toward the feed end from the discharge end (known as counter-current flow). The gas stream can be made up of a mixture of air and combustion gases from a burner, in which case the dryer is called a direct heated dryer. Alternatively, the gas stream may consist of air or another (sometimes inert) gas that is preheated. When the gas stream is preheated by some means where burner combustion gases do not enter the dryer, the dryer known as an indirect-heated type. Often, indirect heated dryers are used when product contamination is a concern. In some cases, a combination of direct-indirect heated rotary dryers are also available to improve the overall efficiency.

Brief Introduction Of  Coal Rotary Dryer

Coal Rotary Dryer  is suitable to dry metallic and nonmetallic mineral, clay in cement industrial and coal slime in coal mine,etc.Coal Dryer can be widely used to dry various materials, and it is simple to be operated.

Applications Of The Coal Rotary Dryer

Coal Rotary Dryer have many applications but are most commonly seen in the mineral industry for drying sands, limestone, stones and soil, ores, fertilizers, wood chips, coal, iron sulphate, filter cakes, sewage sludge, etc

Drum or Shell Variations Of The Coal Rotary Dryer

A Coal Rotary Dryercan consist of a single shell or many, though any more than three drums is not usually necessary. Multiple drums can reduce the amount of space that the equipment consumes. Multi-shell dryers consist of several concentric tubes. Multiple shells allow the dryer to be utilized in a more compact space. The drums are often heated directly by oil or gas burners. The addition of a combustion chamber on the entry end helps ensure efficient fuel usage, and that homogenous drying air temperatures. As the material moves through the rotating drum is heated and moisture released. Some dryers also offer the option to cool, clean, shred, and/or separate the dried material.

Combined Processes Of The  Coal Rotary Dryer

Coal Rotary Dryer is a kind of processing large amounts of material drying machine. Due to the reliable operation, good adaptability, high yield, widely used in metallurgy, building materials, food, chemicals, coal, medicine and other materials. Sand dryer belong to rotating cylinder dryer. Commonly adapted to the powder and granular materials, can also use the mixing material approach drying viscous paste-like material or high water content materials. Especially dry sand, TaiDa sand dryer effect is excellent. Sand dryer with advantages of great capacity of production, wide application, small flow resistance, convenient operation, etc.

 Coal Rotary Dryer working principle

Coal sent to the hopper by the belt conveyer and bucket elevator, and the angle of materials, so that material flows into the sand dryer. Dryer cylinder is a rotating cylinder that has a certain inclination with horizontal linen through the hopper feeder into the feeding pipe, thereby entering the feeding end. The feeding pipe inclination is greater than the naturae. Material from the high-end to join, heat carrier from the low-end entry, countercurrent contact with material, also have heat carrier and material flow into the cylinder together. With the rotating cylinder materials by gravity run to the lower end. Wet material in the cylinder body to move forward, heat by heat carrier directly or indirectly, so that the wet material to be dried, then at the discharge end through a belt or a screw conveyor send out. In sand dryer inner wall of the cylinder is provided with a copy board. Its role is to bring up material then down, increasing the contract surface of material and gas flow, in order to improve the drying rate and promote material progress. Heat carriers are generally divided into hot air, flue gas. Heat carrier through the dryer, then the material in the gas was collected by cyclone dust collector. If need to further reduce the exhaust gas dust content, also should dust by the bag dust collector.
