Dingli Brand Alloy Steel Plate Sedimentary Rock Dryer for Mining Industry

Second, 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. the hot blast stove type is rationally selected to optimize its internal structural design and masonry quality, reduce the air leakage rate, reduce the oxygen content in the hot air to less than 5%, and the temperature of any process requiring 700-1100°C can be arbitrarily controlled and used as a dryer. Providing a homogeneous and stable heat source is a reliable guarantee for the high-strength operation of the mineral slag dryer. 4. the measurement and control technology system adopts a computer operation platform and frequency conversion PLC control technology, online interlocking control of temperature, pressure, oxygen concentration, device speed and other process parameters, to achieve automatic detection and control of the entire system, with centralized, on-site switching function, guarantee The system operates with maximum output, optimal quality, most energy-saving mode, and safe explosion-proof operation. 5. optimize the configuration of gravity settlement + cyclone dust collector + wet / bag dust collector, dust concentration <30mg/Nm3, to ensure that the exhaust emissions standards. 6, the first modular design, manufacturing, transportation, installation, service concept and assembly test platform, to optimize the design and manufacturing, more convenient transportation and installation services to return customers, to ensure maximum customer benefits. 7. solve the problem that the water vapor returns to the material after the system temperature decreases during the same direction movement caused by the dehumidification of the conventional dryer, and increase the drying efficiency to achieve the purpose of deep dewatering. 8. the dryer adopts the double sealing mode of fish scales or mazes and expandable graphite packing mechanical seals to ensure that the dryer system is closed and oxygen-tight and safe to operate.
