Brief introduction of coal dryer 

A coal dryer, also called a rotary dryer, is continuously working equipment to process a large number of materials. Moisture content after drying could reach 10% below (moisture content is adjustable by the control system). Due to the reliable performance, high operation flexibility, wide application, high handling capacity, coal dryer has a good drying effect for raw coal, coal slime, lignite, coal cinder, anthracite, coal powder, fly ash, etc. Materials that are dried by coal dryers could be used for gas making, power plants, home heating, and blast furnace and are convenient to transport. It is widely used in metallurgy, chemical, coal, mining industry, etc. coal dryer is energy-saving and environment-protecting equipment that not only improves the utilization of waste, reduces environmental pollution, but also creates a good economic benefit and social benefit.

Coal dryer has been used widely both in China and other countries. For example, Shanxi Datong coal industry group use it to dry coal slime, Australian client Coal Mining LLC use it to dry raw coal and South Africa client use it to dry raw coal. Coal dryer produced by us has been sold to many countries, such as Australia, India, Malaysia, Philippines, Indonesia, South Africa, Russia, etc. Now our drying equipment is running normally, clients speak highly of our coal dryer.

The coal dryer manufactured by Zhengke has passed the inspection of Henan Quality Supervision Bureau, ISO9001 international quality management system certification, Europe CE certificate standard, Russian GOST certificate, etc. Meanwhile, we had applied many patents of coal dryers to the State Patent Office and were well-known in the drying equipment industry.

Features of Zhengke Coal dryer

1. High drying efficiency, good drying effect. Coal dryer is continuously working drying equipment, used “feeding at one end and discharging at the other” method for drying materials. Due to the high moisture content, high stickiness of raw coal, coal slime, and lignite, we make a special design of the inside structure; the coal dryer has high drying efficiency. We could control and adjust the final moisture content to the client's request.

2. Energy-saving, environment-protecting, no pollution, no noise. Zhengke coal dryer could dry raw coal, coal slime, lignite, then reuse them. This improves resource utilization and reduces dust pollution. Due to the special design of mechanical structure and electricity control, the coal dryer works at low power. Also, the coal dryer is equipped with multistage dust collecting equipment to meet the national standard of environment protection. Reduce the environmental pollution from equipment; it is a kind of good energy conservation and environmental protection equipment. Our coal dryer adopts an enclosed structure; no air pollution and noise pollution will happen during the drying process.

3. Wide application range, low request for the working environment. Zhengke coal dryer is applicable for every country in the world. We could make some adjustments according to the different situations in different countries, such as voltage, engineering design requirement, geographical conditions, etc. As to the working environment, Zhengke coal dryer could work normally in severe cold, high temperature, plateau, etc.

4. Simple installation. The coal dryer could work directly on a horizontal hardened site. In the running, no vibration happens. It is also convenient to transfer and transport the equipment.

5. Few workers, simple operation, easy maintenance. To client request, Zhengke could provide semi-automation and a total automation production line. Only regular maintenance to the instruction is needed. It is very convenient to maintain.

6. High safety. The transmission parts all adopt enclosed or semi-enclosed design to the equipment standard of security, such as transmission shaft, motor, belt pulley, etc. This ensures the safety of equipment and workers.

Working principle of coal dryer

The coal dryer is placed at an inclination of 3-5°. Material is sent to the inlet by feeding device, then spiral feeders push materials into the drum from feeding end to discharge end. Hot air will be drawn into the drum by a draft fan and exchange heat with materials constantly. As the drum rotates, materials are lifted and scattered by lifting boards repeatedly under gravity and move toward the lower end. As coal moves forward, it gets heat directly and indirectly from the heating medium. Thus, coal gets dried and discharged at the outlet. On the inner of the cylinder, lifting boards are equipped to lift materials and scatter them. This would spread the contact surface to improve the drying rate and promote materials to move forward. On the feeding end, a movable grate could break big lumps to increase the heating area, shorten drying time, and improve drying efficiency. On the inner wall of the drum, a movable steel chain would beat the drum repeatedly to prevent sticky material stick on the wall. The heating medium could be hot air, flue gas, etc. Usually, a cyclone collector would collect the dust that the heating medium entrains. If you want to reduce dust content further, a baghouse or wet scrubber may be needed.
