  • Comments 0

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 material such as slag, clay, limestone, cement, chemicals, etc. It is used in the works of construction industry, chemical industry, and metallurgical industry and so on. Limestone dryer, Cement rotating dryer and Drum dryer are the main products made by our company.

Dryer machine which is also known as rotary dryer is the key equipment used for drying different materials with humidity or granularity in various fields. According to its shape, it is also called drum dryer. China is one of the major countries manufacturing dryer and is also the best-selling productor in the world. Especially Henan Hongxing Mining Machinery Co., Ltd is one of the best sellers in those companies manufacturing dryer in China. As the most important manufacturing base of mining machine, China dryers and rotary dryers are the most popular products in the market no matter whether they are at home and abroad.

Indirect Heat Transfer Dryer

The indirect heat transfer dryer made by our company is mainly used in the works of building materials, chemical industry cement plant for drying limestone slag, driving device, supporting device and sealing ring. Advantages of indirect heat transfer dryer are followings: reasonable structure, high efficiency, low energy consumption and convenient for transportation. Indirect heat transfer dryer employs the similar principles of operation to direct dryers, but there are still some differences between the two, the fundamental difference is that the method of heat transfer is predominantly by conduction as opposed to convection. These units are sometimes referred to as contact dryers.

Working Principle:

Materials are sent to the hopper of rotary dryer by belt conveyor or bucket elevator, Materials enter the barrel installed with slope to horizontal line from the higher side, and hot air enters the barrel from the lower side, then materials and hot air mix together. Materials go to the lower side by gravity when the barrel rotates, lifters on the inner side of barrel lift materials up and down to make materials and hot air mix completely in order to improve the efficiency of the producing.

Application of Dryer Machine:

Rotary dryers can be widely used to dry various materials, such as metallic and nonmetallic mineral, clay in cement industry and coal in coal mine, etc, and it is quite easy to be operated and the workers can handle with them in a short time. As a professional manufacturer with many years’ experiences on mining machinery, Henan Hongxing Mining Machinery Co., Ltd. can send our technicians to the jobsites of the customer to train the worker and to guide the operation on those kinds of dryer machines produced by our company, such as Rotary dryer, Limestone dryer, Drum dryer, Cement rotating dryer and so on. We won’t let every customer down on our products and our service.

As the professional manufacturer of complete sets of mining machinery, such as jaw crusher,ball mill, Henan Hongxing is always doing the best in products and service.
