Product Features

1. the mineral slag fixed-speed quantitative feeder solves the problem of feed uniformity in the feeding and drying machines, overcomes problems such as intermittent feeding, material blocking, and large instantaneous amount of material, and is a prerequisite for improving the evaporation intensity.

(1)The uniquely design of hopper and feeding mechanism overcame the intermittent feeding and flickering problems caused by uneven feeding;

(2)A large angle non-powered screw propeller is installed at the feeding end of the drum, which not only uniformly feeds the incoming mineral slag to the drum drying section, but also further cuts and disperses the bulk mineral slag.

2. optimizing the internal structure of the dryer maximized the heat exchange area between the material and the hot air is the basis for improving the evaporation intensity.
(1) Continuously optimize the internal structure of the drum and the design of the lifting plate. The final shape is the unique drum internal lift plate structure and mixing zone layout with different functions. The roller full section "Material curtain" has no dead space, no gaps, and maximum the increase of the limit of the heat exchange area between the mineral slag and the hot air mass causes the moisture in the mineral slag to quickly increase in temperature, vaporize and evaporate, and will be taken away by hot air.
(2) Patented layered rotary drum dryer. According to the law of different size of particles in inside of the roller the speed of heating is way different, set up a multi-component drying device, put small size, control of small particles of material due to excessive drying to chalking, heat of inside and outside of large particles the material is not uniform dryness, we need to ensure dry uniformity.

3. Reasonably select the hot blast stove type, optimize its internal structure design and masonry quality, reduce the air leakage rate, reduce the oxygen content in the hot air to less than 5%, and adjust the temperature point at will for any process requirement of 700-1100°C, which is the best for the dryer. Providing a homogeneous and stable heat source is a reliable guarantee for the high-intensity operation of the mineral material and slag dryer.

4. The measurement and control technology system adopts the computer operation platform and frequency conversion PLC control technology, and the process parameters such as temperature, pressure, oxygen concentration, and equipment speed are interlocked and controlled online to realize automatic detection and control of the entire system. It has centralized and local switching functions to ensure The system operates stably with the maximum output, the best quality, the most energy-saving mode, and safe explosion-proof.

5. Optimize the configuration of gravity sedimentation + cyclone dust collector + wet / bag filter three-stage dust collection and dust removal equipment, dust concentration < 30mg/Nm3, to ensure that the exhaust gas discharge meets the standard.

6. The first modular design, manufacturing, transportation, installation, service concept and assembly and test machine platform to return customers with more optimized design and manufacturing, more convenient transportation and installation services, and ensure the maximum benefit of customers.

7. Solve the problem of water vapor returning to the material after the temperature of the system drops during the same direction of movement caused by the downstream dehumidification of the traditional dryer, improve the drying efficiency and achieve the purpose of deep dehydration.

8. The dryer adopts double sealing mode of fish scale or labyrinth and expandable graphite packing mechanical seal to ensure the safe operation of the dryer system in a sealed and oxygen-free manner.
 

Working Principle

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 pick 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.
