Mineral Powder Rotary Dryer

Brief introduction of mineral powder dryer

A mineral powder dryer is continuously working equipment to process a large number of mineral powders. 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, mineral powder dryer has a good drying effect for mineral powder, slag, iron powder, fluorite powder, mill scale, steel slag, ore sand, metal powder, etc. Mineral powders that are dried by mineral powder dryer could be used for metallurgy, chemical reagent, and are convenient to transport. It is widely used in metallurgy, chemical, coal, mining industry, etc. Mineral powder 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.

A mineral powder dryer produced by us has been in operation worldwide. For example, in steelwork in Hebei, China, the client uses it to dry iron powder, and then make the powder into briquettes. In steelwork in Laiwu, Shandong, clients use it to dry mill scale and then make them into briquettes for reuse. In Changsha, Hunan, the client uses it to dry fluorite powder which is used as a cosolvent in steelwork. Mineral powder dryers have been sold to many countries, such as India, Malaysia, the Philippines, Indonesia, Oman, Mexico, etc. Now our drying equipment is running normally, clients speak highly of our mineral powder dryer.

Mineral powder 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 mineral powder dryers to the State Patent Office and were well-known in the drying equipment industry.

Features of Zhengke mineral powder dryer

1. High drying efficiency, good drying effect. Mineral powder dryer is continuously working drying equipment. Used the “feeding at one end and discharging at the other” method for drying mineral powders, the mineral powder 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 mineral powder dryer could dry mineral powder, slag, ore sand, tailings, then reuse them. This improves resource utilization and reduces dust pollution. Due to the special design of mechanical structure and electricity control, the mineral powder dryer works at low power. Also, the mineral powder 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 mineral powder 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 mineral powder 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 requirements, geographical conditions, etc. As to the working environment, Zhengke mineral powder dryer could work normally in severe cold, high temperature, plateau, etc.

4. Simple installation. A mineral powder 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.

Technical parameter of mineral powder dryer

Note:The above technical parameters are for reference, can be separately designed according to the customer’s actual situation.

Working principle of mineral powder dryer

A mineral powder dryer is placed at an inclination of 3-5°. Mineral powder 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 mineral powder moves forward, it gets heat directly and indirectly from the heating medium. Thus, the mineral powder 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.
