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. 
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 drying process.
1. The fixed-speed and quantitative feeder is used to solve the uniformity of feeding and traveling in the dryer, which overcomes the previous problems of intermittent feeding, material blocking, and large instantaneous material volume. It is the premise of improving the evaporation intensity.
2. Design a unique buffer silo and feeding mechanism to overcome the problem of intermittent feeding or fluctuations caused by uneven feeding;
3. A large inclination unpowered screw propeller is installed at the feed end of the drum, which not only uniformly feeds the incoming mineral slag into the drying section of the drum, but also further cuts and breaks up the large slag;
4. Optimize the design of the internal structure of the dryer to maximize the heat exchange area between the material and the hot air quality, which is the basis for improving the evaporation intensity.
5. Continuously optimize the design of the internal structure of the drum and the lifting plate, and finally, finalize it into the unique structure of the internal lifting plate of the drum and the mixed interval layout of different functions. The full section of the drum has a uniform "material muzzle" without dead corners and no gaps. The heat exchange area between the mineral slag and the hot air is increased to the limit so that the water in the mineral slag quickly rises up and vaporizes and is taken away by the hot air.
6. Original patented technology of layered drying of rotary drum dryer. According to the law of heating speed and travel speed of different particle size particles inside the drum, a multi-component layer drying device is set up, and the small grate is large to control the pulverization of small particles due to excessive drying, and the heating of large particles is different inside and outside. The uneven drying phenomenon ensures the uniformity of drying.
7. Reasonable selection of hot blast stove type, optimize its internal structure design and masonry quality, reduce air leakage rate, reduce the oxygen content in hot blast below 5%, 700-1100ºC arbitrary process requires temperature points to be adjusted at will, as a dryer Providing a homogeneous and stable heat source is a reliable guarantee for the high-intensity operation of the mineral slag dryer.
8. The measurement and control technology system adopts computer operating platform and frequency conversion PLC control technology (optional), and online interlocking and interlocking control of process parameters such as temperature, pressure, oxygen concentration, equipment speed, etc., to achieve automatic detection and control of the entire system, with centralized and local The switching function ensure that the system runs stably with maximum output, best quality, most energy-saving mode, safe and explosion-proof.
9. Optimized configuration of gravity sedimentation + cyclone dust collector + wet/bag dust collector three-stage dust collection and dust removal equipment, dust concentration <50mg/Nm3, to ensure that the exhaust gas meets the emission standard.
10. The first modular design, manufacturing, transportation, installation, service concept, and assembly test machine platform to return customers with more optimized design and manufacturing, more convenient transportation and installation services, and to ensure the maximization of customer benefits.
11. Solve the problem of water vapor returning to the material after the temperature of the system decreases during the same direction movement caused by the downstream dehumidification of the traditional dryer, improve the drying efficiency, and achieve the purpose of deep dehydration.
12. The dryer adopts fish scales or labyrinth, expandable graphite packing type mechanical seal dual sealing mode, to ensure the safe operation of the dryer system with closed oxygen.
