Rotary dryer is an industrial dryer that is used to dry material by eliminating or reducing the moisture content. As a kind of mining machine, the rotary dryer is widely used to dry a variety of materials such as slag, clay, limestone, cement, chemicals, etc. It is used in the construction industry, chemical industry, metallurgical industry, just to name a few. We manufacture and supply China dryers such as limestone dryer, cement rotating dryer and drum dryer and others.

Working Principle of Rotary drying Machine

Rotary dryer is mainly composed of rotary part, lifting board, transmission part, supporting part and seal ring. Since the dryer machine is obliquely installed, the materials flow to the lower end of the machine under the gravity and the rotation of the machine, and on the other hand, the materials are repeatedly lifted by the lifting board to the higher end and then spread down constantly, so that the materials will form a even curtain inside the cylinder and conduct heat exchange with the hot air inside the cylinder. Since the materials constantly spread and the water contained in them will be dried, thus achieving the aim of drying.

Indirect Heat Transfer Dryer

The indirect heat transfer dryer manufactured by our company is mainly used in building materials, chemical industry, cement plant for drying limestone and slag, driving device, supporting device and sealing ring. The dryer has the advantages of reasonable structure, high efficiency, low energy consumption and convenient for transportation. Indirect dryers employ the similar principles of operation to direct dryers. However, the fundamental difference is that the method of heat transfer is predominant by conduction as opposed to convection. These units are sometimes referred to as contact dryers.

Features of Our Rotary Drying Machine

1.Rotary drying machine manufactured by Henan Centbro adopts new multi-stage combined feeding device, which can overcome the phenomenon of "wind tunnel" compared to traditional dryer, so as to improve the utilization of heat energy and reduce the consumption of coal.

2.The rotary dryers can be equipped with various combustion furnaces, such as: high-temperature fluidized bed, grinding combustion furnace and artificial coal stove.

3.Gear isreplaceable, which helps to save cost and reduce maintenance time.

4.The centralized control system can realize automation management for large enterprises.
