Product Description Industrial Slag Dryer Introduction Slag dryer is widely used in building materials, metallurgy, mineral processing, chemical industry, cement and other industries, and can be used to dry slag, calcium carbide slag, limestone, clay, river sand, quartz sand, water slag and other materials. The slag dryer is suitable for a variety of combustion furnaces: high temperature boiling furnace, coal grinding pulverizing furnace and artificial coal stoking furnace. The current industrial slag tumble dryer is divided into two processes: high temperature hot air drying and low temperature steam drying. The former is called direct heating tumble dryer, which uses gas, fuel oil, coal-fired, mixed fuel, biomass fuel, etc. as heat sources. The hot blast stove provides heat and outputs the necessary heat and temperature to meet the needs of rapid drying of wet materials; the latter is a tube bundle type tumble dryer for indirect low-temperature drying, which is mainly used for steam waste heat from power plants, boiler plants and other units. Fast drying of wet materials. The current industrial dryer integrates environmental protection technologies such as clean fuel, multi-stage dry and wet dust removal, fully sealed drying structure, and enhanced thermal insulation layer. Working Principle The mineral slag tumble dryer is mainly composed of a hot blast stove, a belt feeder, a tumble dryer, a belt discharger, an induced draft fan, a cyclone, a bag filter (or a wet filter) and an operation control system. constitute. The equipment adopts a co-current (or counter-current) drying process. Its working principle is as follows. After the wet material enters the drying drum, it is divided into the following working areas: 1. In the material guide area, the mineral slag enters this area and contacts with the high temperature hot air to quickly evaporate the water, and the material is guided into the next work area under the guide plate with large lead angle; 2. In the plate copying area, the ore slag is picked up by the plate in this area to form a material curtain state. At this time, the material is fully contacted with the hot air, and the moisture in the ore slag is rapidly evaporated and stripped into water vapor, and the water vapor is drawn by the induced draft fan. In this area, the ore slag is dried to a loose state with a moisture content of less than 5% (or lower), and after heat exchange, the material reaches the required moisture state and enters the final outlet. material area; 3. In the discharge area, the drum does not have a copy plate in this area, and the material rolls and slides to the discharge port in this area to complete the entire drying process. Product Features 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 the sudden big and small problems caused by uneven feeding; (2) A large inclination unpowered 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 l
