mineral powder dryer using high temperature and fast drying

Mineral Powder Dryer Overview

Mineral powder dryer is suitable for drying materials with high moisture, high specific gravity and fine particle size, such as mineral powder, slag, limestone powder, water slag, etc. It is widely used in building materials, metallurgy, chemical industry, mining and cement industry.
Mineral powder dryer can not only get rid of water, but also effectively remove oily pollutants on the surface of the material, which is convenient for subsequent processing and transportation. As a mainstream product in powder drying equipment, the mineral powder dryer is characterized by compact structure, stable operation and strong adaptability.

Features of the Mineral Powder Dryer

1. Reasonable structure: the whole machine consists of rotary cylinder, combustion furnace, feeding system, discharging system, dust collector, induced draft fan and intelligent control system, compact structure, easy to maintain.
2. Even drying: the internal setting of multiple sets of spiral lifting plate and platen, so that the material in the cylinder uniform distribution, full spreading, and full contact with the hot air, drying effect is remarkable.
3. Adjustable: the equipment is equipped with adjustable blades, variable speed shaft and hot air temperature control system, according to the material characteristics of flexible adjustment of process parameters.
4. Multi-heat source compatibility: natural gas, coal, biomass fuel, heavy oil and other heat sources can be used, adaptability.
5. Energy saving and environmental protection: supporting high efficiency cyclone dust collector and bag type dust collector, reduce the dust content in the exhaust gas, in line with the environmental protection emission standards.

Advantages of Mineral Powder Dryer

1. High efficiency and energy saving: the use of downstream and countercurrent combined drying process, high thermal energy utilization, energy saving of more than 20% than the traditional dryer.
2. Strong processing capacity: equipment overload resistance, suitable for large quantities of continuous production, large capacity, good stability.
3. The material to adapt to a wide range: not only suitable for mineral powder, but also can dry slag, quartz sand, river sand, limestone powder, clay and other high humidity and high specific gravity materials.
4. Low operating costs: less wear and tear of equipment, simple maintenance, long service life, comprehensive operating costs significantly reduced.
5. Good product quality: after drying, the moisture content of mineral powder is uniform, the particles are loose, no lumps, which is convenient for subsequent processing or storage.
6. Intelligent control: modern mineral powder dryer is equipped with PLC intelligent control system, which can realize the automatic monitoring and adjustment of temperature, humidity, air volume and other parameters, and improve the convenience of operation.

Working Principle of Mineral Powder Dryer

1. Mineral powder is fed into the hopper by belt conveyor or bucket elevator, and then evenly fed into the dryer cylinder by the feeding machine through the feeding pipe.
2. The cylinder of the equipment is slightly tilted and continuously rotating, and the material moves slowly to the downstream end with the help of gravity and the rotating force of the cylinder.
3. At the same time, high temperature hot air (heat carrier) from the low end of the cylinder body into the formation of counter-current or parallel flow contact with the material, quickly take away the moisture.
4. Inside the cylinder, many sets of coping boards constantly lift up the material and scatter it down, increasing the contact area between the material and the hot air, and speeding up the drying speed.
5. The dried material is discharged from the low end and sent out through the discharge screw conveyor; the fine dust carried by the exhaust gas is treated by cyclone dust collector and bag filter and discharged according to the standard.
6. The heat source can be coal-fired furnace, gas furnace, biomass combustion furnace, etc., which can be flexibly configured according to the user’s demand.

Application Fields of Mineral Powder Dryer

1. Building materials industry: drying cement slag, limestone powder, quartz sand, etc.
2. Metallurgical industry: processing blast furnace slag, iron ore powder, nickel slag, etc.
3. Chemical industry: dry chemical powder, catalyst carrier, clay powder, etc.
4. Mining industry: drying copper ore powder, aluminum ore powder, manganese ore powder and other minerals fine powder
5. Environmental protection field: drying sludge, tailings, industrial waste and other water-containing solid waste.
6. Other fields: suitable for drying viscous or easy to agglomerate fine granular materials.
