2.8*20 dryer Reasonable design of raising board and angle, ensure the material well-distributed and dry wit

2.8*20 dryer

Dryer is mainly used for drying wet materials in building construction, metallurgy and chemical industries. It can dry various materials with strong adaptability. Besides, it is a common drying device in cement plant with simple and reliable operation.

In our company, this series applies the new type scatter plate device, and it has many functions, such as guide direction, flow on an average, scatter the material and so on. And it can make the material in the thin, average and complete condition. Contact the heat airflow completely and use the heat energy fully. Moreover, it adopts reasonable operational parameter, and compared with general dryers, it reduces the coal and power consumption above 10-15%,and increase the output above10-15%. At present, it is widely used in cement and mining industries.

Working principle:

It mainly consists of revolution body, raising material board, transmission device, supportive device and sealing ring, etc.

The heat source of the dryer comes from the combustion train, and it adopts down-flow heating methods. When the materials enter into the body from the feeding device, it will be pushed back by the spiral raising board. As the dryer is placed in an inclined position, the materials will be down to the lower end under the influence of gravity and rotation, but the raising board will be threw them to the upper end for scattering. This procession makes the material well-distributed in the body, and ensures the full heat exchange with the heat wind. After repeated cycle with this procession, the moisture content will be dried.

Features and Benefits:

Reasonable design of raising board and angle, ensure the material well-distributed and dry with less times, it has reliable operation and high energy utilization ratio, simple maintenance.Adopt an adjustable center tug structure, the good cooperation of the tug and the rolling ring reduce the attrition and energy consumption.The special structure of the thrust roller, decrease the horizontalthrust, when the machine working in inclination station, and it has strong ability of anti-overloading, steady operation and high reliability.High temperature resistance, it can use the high temperature to dry the material quickly, Strong adaptability, large capacity, low fuel consumption, low drying cost.
