Rotary Dryer

Dryer equipment is mainly used for drying materials with a certain humidity or particle size in mineral processing, building materials, metallurgy, chemical and other departments.

Product Introduction

Rotary Dryers can be divided into two types: industrial and civilian. Industrial Rotary Dryers are also called drying equipment or Rotary Dryers. Civilian Rotary Dryers are a type of washing machine. They are generally used to remove clothing and other textiles after dehydration. of moisture.

Application of dryer

Dryer equipment is mainly used for drying materials with a certain humidity or particle size in mineral processing, building materials, metallurgy, chemical and other departments. The dryer is widely used in tea, Chinese herbal medicine, corn, vegetables, food, chicken manure, slag, towel quilt cover, sawdust, coal slime, desulfurization gypsum, compound fertilizer, honeysuckle, straw briquetting fuel, charcoal machinery, wood pellet fuel, sawdust Briquetting, agriculture and animal husbandry engineering and other industries. The main types of Rotary Dryers are, rotary drum dryer, three-pass dryer, three-cylinder dryer, intermittent dryer, direct heat dryer, clothes spin dryer, powder dryer, Professional stone dryer, new dryer, second-hand dryer, industrial dryer, tea dryer, Chinese herbal medicine dryer, corn dryer, vegetable dehydration dryer, food dryer, chicken manure dryer Dryer, tumble dryer, tumble dryer, stone dryer, rotary dryer, flux dryer, automatic dryer, petroleum dryer, electric heating dryer, energy-saving drying machine, clothing dryer, towel and quilt dryer, computer intelligent dryer, steam dryer, gas dryer, slime dryer, slag dryer, sludge dryer, quartz sand dryer Dryer, sand dryer, fly ash dryer, desulfurized gypsum dryer, sawdust dryer, tunnel dryer, dehydration dryer, compound fertilizer dryer, honeysuckle dryer, wine tank dryer etc.

Equipment structure

Mainly used for conveying materials and other media, the materials are stainless steel, carbon steel and so on. The heated gas is introduced into the container mainly through the fan, and the drying effect has been achieved. The main application theory is the direct current hot air drying. Cooling section: The sudden cooling of high-temperature objects will degenerate the material. The main purpose of the cooling section is to gradually cool down, which is mainly reflected in the length of the dryer. The next segment: The material is finally removed from the device from the discharge port.

How the dryer works

Power is generated by electricity, diesel power, wind power, flammable material power, etc., and the ambient air is heated, transported to the surrounding area of the tunnel, and then reaches an appropriate temperature for dehumidification treatment. The specific process is as follows: the 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 supplied by 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. A copy board is installed on the inner wall of the cylinder, and its function is to copy and sprinkle the material, so as to increase the contact surface between the material and the air flow, so as to improve the drying rate and promote the advancement of the material. Heating medium is generally divided into hot air, flue gas and so on. After the heat carrier passes through the dryer, a cyclone dust collector is generally required to capture the materials in the gas. If it is necessary to further reduce the dust content of the exhaust gas, it should also be discharged after passing through a bag filter or a wet filter.

Dryer equipment features

The drying strength is high, and the entire surface area of the particles is extremely dry effective area due to the high dispersion of the material in the air flow.

Short drying time. Airflow Rotary Dryers are simple in structure, occupy a small footprint, and are easy to build and maintain.

Large processing capacity and high thermal efficiency. When drying unbound water, the thermal efficiency can reach 60%. The dryer achieves "zero horizontal thrust", which greatly reduces the wear of the supporting roller, and the cylinder runs smoothly and reliably.

The dryer adopts "aligning type supporting roller device", so that the cooperation between the supporting roller and the rolling ring is always in linear contact, thus greatly reducing the wear and power loss.
