Product Features

Product structure advantage
1. The ore slag constant speed quantitative feeder solves the feeding uniformity in the dryer, and overcomes the previous problems of intermittent feeding, material blocking, and large instantaneous material volume, which is the premise to improve the evaporation intensity.
(1) The unique buffer silo and feeding mechanism are designed to overcome the intermittent feeding or sudden big and small problems caused by uneven feeding;
(2) A large inclination non-power screw propeller is set at the feeding end of the drum, which not only evenly sends the incoming ore slag into the drum drying section, but also further cuts and breaks up the large pieces of ore slag;
2. Optimizing the design of the internal structure of the dryer to maximize the heat exchange area between the material and the hot air quality is the basis for improving the evaporation intensity.
(1) Continuously optimize the design of the internal structure layout of the drum and the lifting plate, and finally finalize the unique structure of the inner lifting plate of the drum and the mixed section layout of different functions. Maximize the heat exchange area between the ore slag and the hot air, so that the water in the slag can quickly heat up, evaporate, and be taken away by the hot air;
(2) The original patented technology of layered drying of rotary drum dryer. According to the law of the heating speed and traveling speed of the materials with different sizes and particle sizes in the drum, a multi-component layer drying device is set up, and the small grate is placed in a large grate to control the pulverization of the small particle material due to excessive drying and the different heating inside and outside the large particle material. Uneven drying phenomenon to ensure drying uniformity.
3. Reasonably select the type of hot blast stove, 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 of any process requirements at 700-1100 °C at will, which is the drying machine. Providing a homogeneous and stable heat source is a reliable guarantee for the high-intensity operation of the slag dryer.
4. The measurement and control technology system adopts computer operation platform and variable frequency PLC control technology, and the process parameters such as temperature, pressure, oxygen concentration, equipment speed and other process parameters are interlocked and controlled online to realize automatic detection and control of the entire system, with centralized and local switching functions to ensure The system operates stably with the largest output, the best quality, the most energy-saving mode, and safe explosion-proof operation.
5. Optimize the configuration of gravity sedimentation + cyclone dust collector + wet/bag type dust collector three-stage dust collection and dust removal equipment, dust concentration <30mg/Nm3, to ensure that the exhaust gas is discharged up to the standard.
6. The first modular design, manufacturing, transportation, installation, service concept and assembly and test machine platform, return customers with more optimized design and manufacturing, more convenient transportation and installation services, and ensure the maximum benefits of customers.
7. Solve the problem of water vapor returning to the material after the temperature of the system decreases during the co-directional 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 the double sealing mode of fish scale or labyrinth, expandable graphite packing type mechanical seal to ensure the safe operation of the dryer system with closed oxygen.

Working Principle

The gypsum tumble dryer is mainly composed of a hot blast stove, belt feeder, tumble dryer, belt feeder, induced draft fan, cyclone dust collector, bag filter (or wet dust collector), and operation control system. The equipment adopts the fair current (or countercurrent) drying process. The working principle is as follows: After entering the drying drum, the wet materials are spitting into the following working areas: First, the material guiding zone. Plaster enters this zone and contacts with high-temperature hot air to quickly evaporate moisture. The material is in a large lifting flight angle and is transferred to the next working area under the splicing; Second, the copy board area, in which the gypsum is dropped and picked up by the lifting flight to form the material curtain state. At this time, the material is in full contact with the hot air, and the moisture in the plaster is rapid. The evaporative stripping becomes water vapor, and the water vapor is drawn away immediately by the induced draft fan to achieve the purpose of gypsum drying; the gypsum is dried in this zone to a loose state with moisture below 5-10% (or lower) after heat exchange of the material The required moisture state is reached and the final discharge zone is entered. The third is the discharge zone. The roller does not have a copy board in this zone. The material slides in this zone to the discharge port to complete the entire drying process.

Note: 1. The internal structure of desulphurization gypsum and gypsum mineral powder drying equipment is completely different, for more details, please contact us. 2. The production capacity of the equipment is directly related to the proportion of desulphurized gypsum and gypsum mineral powder to reduce the water content. The proportion of precipitation is large and the production capacity of the equipment is reduced accordingly.
