Large Capacity Rotary Drum Mineral Slag Ore Powder Concentrate Mining Dryer Machine

Product Description

Product Description

Zhengzhou Dingli is currently the most professional and most authoritative enterprise engaged in the research and development of drying equipment in China. The mineral slag dryer is meticulously researched and developed for drying slag, slurry, and other materials. After more than 20 years of drying practice and researches, it has been continuously improved. With its advanced technology, high efficiency, low energy consumption, stable operation, and easy operation and maintenance, safety and environmental protection, praised by users, more than 100 sets of drying equipment are perfectly operating in China and around the world. This type of equipment is widely used in cement, mining, building materials, chemicals, food, metallurgy, chemical, fertilizer production, slag, clay, and other industries. The equipment can be customized according to the type of material, depth of precipitation and user needs to meet the individual needs of each user.

Mineral slag dryer is mainly composed of hot air furnace, belt conveyor, rotary drum dryer, belt conveyor, induced draught fan, cyclone dust collector, bag dust collector (or wet dust collector) and operation control system. The equipment adopts the fair current (or countercurrent) drying process.

Materials:Widely used for drying slag, mineral, ore, chrome concentrate, lithium ore slag, etc.

Application:Drying mineral slag and ores for further processing.

Working principle

After entering the rotary drum, wet mineral slag passes through three main zones. In the guiding zone, it contacts high-temperature hot air for rapid surface moisture evaporation and is conveyed forward by guide plates.

In the lifting zone, specially designed flights continuously raise and disperse the material into a uniform curtain, ensuring full heat exchange with the hot air. Moisture quickly evaporates and is removed by the induced draft fan, reducing the moisture content to below 5% (or lower) and forming a loose, dry state.

Finally, in the discharge zone, the drum has no lifting plates, allowing the dried material to smoothly roll out, completing the drying process.

Product Advantages

1. The dryer is made of alloy steel plate manufacturing,the wear-resisting 3-4 times of ordinary steel , the service life of the equipment is more than 10 years.
2. Material initial moisture content 15%, final moisture to ensure below 0.5-1%,which is the preferred products of the cement plant, GGBS and dry mortar production line.
3. The dryer thermal efficiency is as high as 80%, at the same time, the total power is low, 40% energy saving.
4. The fuel can be adapted to the coal, oil, gas,it can be dried under 20-40mm particles material, aggregate, powder material.
5. The dryer covers an area of about 40% lower than single drum dryer and civil investment reduced by about 50%.
6. No air leakage phenomenon, solved the sealing difficulties, modular units, installation is convenient. 7. The discharge temperature is < 50 ,which can be directly feed libraries, without cooling.
