Rotary dryer sludge rotary drum dryer rotary vacuum dryer manufacturer


Single cylinder Rotary dryer is widely used for drying slag limestone,coal powder,slag,clay,etc.The dryer can also be used in building materials,metallurgy,chemical, and cement industry.Rotary 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.

Main Features

  • The drying strength is high, and since the materials are highly dispersed in the gas stream, the entire surface of the particles is actively dry and effective.
  • Short drying time.
  • The air dryer has a simple structure, a small footprint, and is easy to build and maintain.
  • Large amount of processing, 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 brace wheel and ensures smooth and reliable operation of the barrel.
  • Dryer adopts "aligning roller device", so that the support of the roller and the roller will always be in linear contact, thus greatly reducing wear and power loss.

1. Yuhong coal dryer, with strong overload capacity, large quantity, less fuel consumption, low dry cost; Applies the downstream drying method, flue gas and wet material in the dryer on one side of the dryer, can take advantage of the high temperature gas to achieve high evaporative force, low temperature dryer output, with high efficiency thermal;

2. Can change the working parameters according to different material properties, the material in the drying cylinder body can form a durable curtain fabric and more convenient heat exchange;

3. New type of feeding and unloading device, preventing food blockage of drum dryers, uninterrupted and uneven return phenomenon, reduce the load of dust collection system;

4. A type of internal structure, to enhance the cleaning effect of dispersed material and thermal conductivity, remove the cylinder in moisture, has more flexible adaptation of adhesion and moisture of materials;

5. In the new type of coal slurry drying device to achieve "zero thrust", greatly reducing the wear of the wheels, the cylinder has smooth and reliable operation;

6. The dryer acquires a "wheel self-adjusting device", makes the wheel and roller ring with linear contact, thereby greatly reducing wear and energy loss; Adopt the unique technology of large carbon retardation absorption, ensure the uniformity of coal drying.

The quality of building materials continues to increase, energy and raw material consumption are declining year by year, new types of new building materials continue to emerge, and building materials are constantly upgraded. As a result, the requirements for the processing technology of building materials have been continuously improved. For example, the control requirements for impurities and moisture content of raw materials have been continuously improved. Only in this way can products with guaranteed quality be produced.

Customer case

Working principle

The wet material is sent to the hopper by the belt conveyor or the bucket elevator, and then through the feed pipe to the feeding end through the feeder of the hopper. The slope of the feed pipe is greater than the natural inclination of the material so that the material can flow smoothly into the dryer. The dryer cylinder is a rotating cylinder slightly inclined to the horizontal line. The material is added from the higher end, and the heat carrier enters from the low end, and is in countercurrent contact with the material. There is also a heat carrier and the material flow into the barrel together. As the cylinder's rotating material is moved by gravity to the bottom end. During the forward movement of the wet material in the cylinder body, the heating of the heating medium is obtained directly or indirectly, so that the wet material can be dried, and then sent out at the discharge end via a belt conveyor or screw conveyor. A copy board is installed on the inner wall of the barrel, and its function is to copy the materials and scatter them, so that the contact surface of the materials and the air flow is increased, so as to increase the drying rate and promote the advancement of the materials. Heat carrier 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 trap the material contained in the gas. If it is necessary to further reduce the dust content of the tail gas, it should also be discharged after bag filter or wet filter

Heat Source

The heat source of the dryer is coal, electricity, gas, etc.Material hot atmosphere flow during drying and radiant, hot air drying cylinder is the heat flow from the tail, to move forward with a good contact with the material, through the heat conduction, convection and radiation heat transfer make full use of;Pass heat directly to the material, make the material moisture to evaporate in the cylinder body are constantly being, into the mouth of the wind device take out a large number of moisture, wet, prevent secondary pollution caused by the dust outside;Through internal spiral stirring, scavenging, copying plate, press the material movement, complete the drying process;Reverse flow dehumidification to avoid reducing repeat drying procedures.
