Zhengzhou DINGLI is currently the most professional and most authoritative enterprise engaged in the research and development of drying equipment in China. It is the only science and technology enterprise in China's drying industry that integrates design, production, and sales. After nearly 20 years of Fast and steady development has gradually become the leader of the Chinese drying equipment industry. The mineral and tailings slag dryer has been meticulously researched and developed, with its advanced technology, high efficiency, low energy consumption, stable operation, easy operation and maintenance, safety, and environmental protection, praised by users, more than 200 sets of drying equipment are perfectly operating in China and around the world.
This mineral slag dryer is widely used in cement, mining, building materials, chemicals, food, metallurgy, chemical, fertilizer production, slag, clay, and other industries, such as Copper zinc concentrate, copper concentrate, zinc concentrate, iron slag, iron ore tailings, manganese slag, lithium slag, fluorite powder slag, fine iron slag, tailings, etc. 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.
The mineral slag tumble 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. Its working principle as following: After entering the drying drum, the wet materials are spitting into the following working areas: First, the material guiding zone. The mineral slag enters this zone and contacts with high-temperature hot air to quickly evaporate water. Under the circumstance of the large lead angle guide plate, it is transferred to the next work area; the second is the copy board area. The mineral slag is the lifting flight drop and picks up in this area to form the material curtain state. At this time, the material in full contact with the hot blast. The moisture in the material slag is quickly evaporated and stripped into water vapor. The water vapor drawn away immediately by the induced draft fan to achieve the purpose of drying the mineral slag; the mineral slag is dried in this area to moisture content of less than 5% (or lower) In the loose state, after the heat exchange, the material reaches the required moisture state and enters the final discharge area. The third is the discharge area. The drum does not have a copy board in this area. The material is rolling in the area to the discharge port, completing the entire process. Drying process.
| Equipment | Output (T/D) | Moisture content of raw material (%) | Final moisture content (%) | Total Power (kw) | Spatial footprint (m²) |
|---|---|---|---|---|---|
| DLHG1615 | 200 | 20-30% | <5% | 100 | 8*25 |
| DLHG1916 | 300 | 120 | 8*26 | ||
| DLHG2218 | 500 | 160 | 10*35 | ||
| DLHG2520 | 700 | 200 | 10*40 | ||

| DLHG4032 | 2000 | 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. | |||||
