Rotary dryer Overview

 

The rotary dryer is mainly used for drying certain humidity or granularity materials in mineral processing, building materials, metallurgy, chemical industry and other departments. Rotary dryer has strong adaptability to materials, and can dry all kinds of materials, and the equipment is simple and reliable, so it is widely used.

1. The parts have long life and are not easy to wear. The structural design of the supporting wheel is reasonable and the lubrication mode is diversified, so that the supporting wheel is not easy to wear and break the shaft phenomenon, thereby shortening the replacement cycle and improving the service life of the supporting wheel. The barrel of the dryer is made of steel material with high hardness and high toughness. Compared with other materials, the dryer has high wear resistance.

2. The drying strength is high and the efficiency is high. Because of the high velocity of air flow, the material is well dispersed in the gas phase, and the whole surface of the material can be used as an effective area of drying. Therefore, the limited area of drying is greatly increased. At the same time, due to the dispersion and agitation during drying, the gasification surface is constantly updated. Therefore, the drying heat transfer process has great intensity and high efficiency.

3. Simple operation, environmental protection and energy saving. The drier system has good sealing performance and is equipped with a perfect dust removal device, without dust spillover and good operating environment. The LX type multi composite feeder board is used to make the material into the rain like curtain in the dryer, and increase the contact surface between the material and the hot air, so as to avoid the hot and empty occurrence.

4. The structure is advanced and the drying ability is strong. The new internal structure strengthens the cleaning and heat conduction of the dispersed materials, eliminates the stickiness of the inner wall of the cylinder, and is more adaptable to the moisture and stickiness of the material.

 

Working principle

 

The heat source of the dryer comes from the combustion device. The dryer adopts a parallel flow heating mode. Therefore, the material needed to dry is pushed from the feed box and feed into the cylinder, that is, pushed by the spiral plate. As the dryer is tilted, the material flows to the back end under the action of gravity and rotation. On the other hand, the material is repeatedly copied from the sheet, and then continuously raised to the upper end, so that the material can form a uniform curtain inside the tube, and the heat exchange is fully exchanged with the hot gas flow in the cylinder, because the moisture content is repeatedly raised and the moisture contained. It is gradually dried to achieve the purpose of drying.
