The industrial rotary drum dryer is mainly composed of a rotating body, a lifting plate, a transmission device, a supporting device and a sealing ring. The working principle is that the slag is sent to the hopper by the belt conveyor or the bucket elevator, and then enters the feeding end through the feeding pipeline through the feeding machine of the hopper. Rotary drum dryers are widely used in metallurgy, building materials, chemicals, coal washing, fertilizers, ore, sand, clay, kaolin, sugar and other fields.
The rotary drum dryers is widely used in building materials, metallurgy, mineral processing, chemical industry, cement and other industries. The slag drying production line is mainly composed of rotating cylinder, induced draft equipment, high-speed breaking equipment, lifting plate, self-cleaning device, transmission device, conveying equipment, hot air equipment, reducer, support device and sealing device. The complete set of drying equipment has the advantages of reasonable design, excellent production, stable performance, advanced technology, high output, low energy consumption, small footprint and high degree of mechanization.
The dry wet material is sent to the hopper by the belt conveyor or the bucket elevator, and then enters the feeding end through the feeding pipeline through the feeding machine of the hopper. The inclination of the feeding pipeline should be greater than the natural inclination of the material, so that the material can flow into the dryer smoothly. The dryer cylinder is a rotating cylinder slightly inclined to the horizontal. The material is added from the higher end, the heat carrier enters from the low end, and is in countercurrent contact with the material, and some heat carrier and material flow into the cylinder together. With the rotation of the cylinder, the material runs to the bottom end by gravity. During the forward movement of the wet material in the cylinder, the heat is directly or indirectly obtained from the heat carrier, so that the wet material is dried, and then sent out through a belt conveyor or a screw conveyor at the discharge end.
1. The tumble dryer has strong anti-overload capability, large processing capacity, low fuel consumption and low drying cost.
2. The tumble dryer adopts the downstream drying method. The hot air and the wet material enter the dryer from the same side. High temperature air can be used to obtain high evaporation intensity. The outlet temperature of the dryer is low and the thermal efficiency is high.
3. The tumble dryer can change the operating parameters according to the properties of different materials, so that the materials can form a stable full-break fabric curtain in the dryer cylinder, and the quality and heat exchange is more sufficient.
4. The tumble dryer adopts a new type of feeding and discharging device, which eliminates the phenomenon of feeding blockage, discontinuity, unevenness and return of the vertical dryer, and reduces the load of the dust removal system.
5. The tumble dryer achieves "zero horizontal thrust", which greatly reduces the wear of the supporting roller, and the cylinder runs smoothly and reliably.
6. The tumble dryer adopts the "aligning roller device", so that the cooperation between the roller and the rolling ring is always in linear contact, thus greatly reducing the wear and power loss.
7. The tumble dryer can control product moisture according to user requirements.
1. High drying rate: The structure design is advanced, the technical parameter design is more reasonable, and the drying speed of the material is very fast, which can save a lot of working time and improve the efficiency of the entire material processing line.
2. Low operating cost: high degree of automation, advanced engine design, labor costs, energy consumption, maintenance costs, and spare parts costs are very low in the operation process. Compared with other types of drying equipment on the market, this equipment can at least Save a lot of cost for the processing plant.
3. Wide range of application: The industrial dryer equipment can dry slag, clay, coal, metal concentrate and some chemical materials. It has strong adaptability and is not affected by the properties of materials. The operation process is very stable.
4. Long service life: The cylinder and other devices are made of naito grind materials, the sturdiness and nai grindability are greatly enhanced, the quality is better, and the service life is more than 3 times that of the same type of drying equipment.
5. High cost performance: This industrial dryer is self-developed, self-produced and self-sold by our company. There is no middleman to make the difference, and the manufacturing cost is also lower than the same type of drying equipment. Therefore, this industrial dryer The price of the equipment is very economical and cost-effective.
