Working principle of cement dryer

The dryer consists of a cylindrical structure with the cylinder placed horizontally. One end slightly higher and the other end slightly lower. When the dryer is running, the wet material is sent to the hopper via a belt conveyor or a bucket elevator. The material enters the dryer from the higher end of the dryer, the dryer rotates continuously, and the material in the cylinder is brought to a high place and then falls with the rotation. There is a lifting plate on the inner wall of the cylinder, in order to take materials to a high place and evenly spread them, increase the contact area between the material and the air. Some dryers also pass hot air from one end to achieve faster drying of materials.

The Frequent-Asked Questions of Cement Dryer

What is the main heat source of the cement dryer?

The main heat source of the dryer comes from the combustion device, which mainly relies on coal combustion to generate heat.

Does it consume a lot of fuel?

Our rotary kiln dryer choose reasonable operating parameters, coal consumption and electricity consumption reduce 10-15%, greatly reduce the cost of production.

Is it easy to maintain?

The cement dryer adopts advanced technology, reasonable structure design, safe and reliable, simple operation, easy maintenance.

How about the investment and benefit of dryer? Is it proportional?

Our dryer has advantages of long service life, simple operation, high efficiency, good effect, low failure rate, little dust, convenient maintenance and etc. good performance decide good control of the running cost, and gain higher economic efficiency, realize the “small investment, big returns”, cost recovery period will remain basically within 3 months.
