Product Description of Coal rotary dryer
♥. Coal rotary dryer is widely used for drying slag limestone, coal powder, slag, clay, etc. Dryer can also be used in building materials, metallurgy, chemical and cement industry. Dryer mainly consists of dryer body, raw material feeding plate, driving and supporting device, seal ring, etc. Dryer can be generally divided into four types, they are: rotary dryer, triple-drum dryer, indirect heat transfer dryer, vertical dryer. Different kind of dryer has its own characters and advantages, the specific choice of a special dryer depends on different elements.
♥. Coal rotary dryer is a kind of highly efficient, stable and reliable heating drying equipment (dryer), it is designed by Hengxing heavy equipment to dry materials of high moisture or strong stickiness. Rotary dryer has a better performance than tube bundle rotary dryer, blade rotary dryer. Rotary dryer has the features of big capacity, low energy cost and high efficiency.
Application and raw materials of Coal rotary dryer
Dryers are widely used in the tea, and Chinese herbal medicine, corn, vegetables, food, chicken manure, slag, towels, bedding bag, sawdust, coal slurry, desulfurization gypsum, compound fertilizer, honeysuckle, straw briquette fuel, charcoal machine, wood pellet fuel, sawdust briquetting, agricultural engineering, etc.Dryers are widely used in the tea, and Chinese herbal medicine, corn, vegetables, food, chicken manure, slag, towels, bedding bag, sawdust, coal slurry, desulfurization gypsum, compound fertilizer, honeysuckle, straw briquette fuel, charcoal machine, wood pellet fuel, sawdust briquetting, agricultural engineering, etc.
Competetive Advantages of Coal rotary dryer
♥. 1. Three-cylinder dryer can take full advantage of excess heat, reduce heat loss and increase the heat exchange area, making the unit evaporation intensity of the dryer greatly improved, thereby effectively improving the heat energy utilization rate, reducing the energy consumption and making the heat efficiency of three-cylinder dryer improved in a wider range. Compared with single-cylinder dryer with the same efficiency, its heat efficiency is improved about 50% and energy consumption saving doubles.
♥. 2. Because the cylinder length of the three-cylinder dryer is one third of single-cylinder dryer and the base area saves about 60% than the single-cylinder dryer, the base investment is reduced correspondingly.
♥. 3. The dryer drives by adopting the friction between supporting roller and belting leather, and the transmission power is low, thereby reducing the noises when the equipment working.
♥. 4. The cylinder sealing system of the dryer adopts micro-contact technology, with better sealing effect and reducing the dust pollution.
♥. 5. The cylinder and raising material board of the dryer both adopt alloy steel plates which is double service life of common steel plates.
♥. 6. Three-cylinder dryer can use coal, oil, gas as fuel, can dry different shapes of material, such as lump, granular, powder and various materials.
♥. 7.Compact structure, big heating area,smaller installation area drying machines.
Working process of Coal rotary dryer
Materials are sent to hopper of Rotary Drum Dryer by belt conveyor or bucket elevator, then enter the barrel installed with slope to horizontal line from the higher side, and hot air enters the barrel from the lower side, and then materials and hot air mix together. Materials go to thelower side by gravity when the barrel is rotating. Lifters on the inner side of barrel lift materials up and down in order to make materials and hot air mix completely, which is designed to improve the producing efficiency of rotary dryer.
