Zhengzhou Jiutian 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.
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.
| Model | Output (T/D) | Moisture content of raw material (%) | Final moisture content (%) | Total Power (kw) | Area (m²) |
|---|---|---|---|---|---|
| JTHG1916 | 300 | 20-30 | <5 | 120 | 8*26 |
| JTHG2218 | 500 | 20-30 | <5 | 160 | 10*35 |
| JTHG2520 | 700 | 20-30 | <5 | 200 | 10*40 |
| JTHG2820 | 1000 | 20-30 | <5 | 290 | 12*40 |
| JTHG3430 | 1500 | 20-30 | <5 | 420 | 15*46 |
| JTHG4032 | 2000 | 20-30 | <5 | 500 | 15*50 |
| Note: The production capacity of the equipment is directly related to the proportion of mineral slag to reduce the moisture, the precipitation ratio is large, and the equipment production capacity is reduced accordingly. Specific consulting firm. | |||||
Special hopper and quantitative feeding system eliminate intermittent feeding and blockage. Non-powered screw disperses slag evenly, ensuring stable feed and high evaporation intensity.
Unique lifting plates and patented layered drying design create a full-section material curtain, maximizing heat exchange and ensuring uniform drying for both fine and coarse particles.
Low-oxygen hot air furnace (<5% O₂) provides stable heat at 700–1100℃. PLC and frequency control monitor temperature, pressure, speed and oxygen concentration for safe, efficient operation.
Dual mechanical sealing ensures airtight operation. Multi-stage dust collection (gravity + cyclone + bag/wet) keeps dust emissions below 30 mg/Nm³, with modular design for easy installation.
From solution design to equipment manufacturing and on-site installation and commissioning, Jiutian provide complete one-stop services. The equipment is exported to over 100 countries including UK, Russia, Malaysia, the Philippines, Italy, Israel, Indonesia, Malaysia, Ethiopia, Nigeria, Congo, South Africa, Pakistan, India, Egypt, etc. Looking forward to cooperating with you.
