Dehydrating equipment for washing kaolin -- rotary dryer

Kaolin is a kind of non-metallic mineral which is widely used. Pure kaolin has the characteristics of high whiteness, soft texture, easy to disperse in water, good plasticity, high cohesiveness and excellent electrical insulation performance. It has good acid resistance, low cation exchange capacity, good fire resistance and other physical and chemical properties. Because of its good properties, kaolin has become a necessary mineral raw material for papermaking, ceramics, rubber, chemical industry, coating, textile, refractory and national defense industries.


Kaolin dryer It is an indispensable drying equipment for kaolin production, Generally, rotary dryer is used for kaolin dryer It can be divided into direct heat transfer rotary dryer and indirect heat transfer Rotary Dryer In addition to drying kaolin, the dryer can also be used for drying granular and powdery materials in cement, mining, metallurgy, building materials, chemical industry, compound fertilizer production and other industries. Both ends of the main engine of the rotary dryer are highly sealed, which is energy-saving and environmentally friendly. The power consumption is only 30% of that of similar products, and the coal consumption is only 50%. The indexes of materials after drying are higher than the national standards.

Structural composition

Rotary dryer is mainly composed of cylinder device, front and rear supporting wheel device, feeding and discharging device, transmission device and gear cover. There are also auxiliary equipment matching with the dryer: combustion chamber, feeding and discharging equipment, dust collection equipment, etc.

The rotary drum dryer produced by the company adopts a new type of lifting plate device, which has the functions of guiding, equalizing flow and lifting material. It can make the material evenly distributed in the radial section of the dryer, and the curtain can be thin, even and complete, and fully contact with the hot air flow, so as to fully utilize the heat energy. With reasonable operation parameters, the coal consumption and power consumption are reduced by more than 10-15% and the per hour output is increased by more than 10-15%, which has been widely used in various industries.

Characteristics of rotary dryer

1. The rotary dryer has high output, continuous operation and convenient operation. The cylinder has large space, small material flow resistance and high productivity.

2. The structure is reasonable and the manufacturing process is excellent. The pin column replaceable gear is used for the transmission gear, which replaces the traditional cast steel gear, saving the cost and investment, and greatly reducing the maintenance cost and time. Stable operation, energy saving and high efficiency, and less fuel consumption.

3. It has the characteristics of high temperature resistance, and can use high temperature hot air to quickly dry materials.

4. It has strong expansibility and anti overload ability. The design takes into account the production allowance. Even if the output increases slightly, there is no need to replace the equipment.

5. The equipment adopts the structure of self-aligning tugboat. The tugboat and the rolling ring match well, which greatly reduces the wear and kinetic energy consumption.

6. The specially designed block wheel structure greatly reduces the horizontal thrust caused by the tilting operation of the equipment.

7. The centralized control system can be used in the production mode of microcomputer monitoring and management in large enterprises.

8. The utility model has a wide range of application, can dry powder, granular and strip materials, and is easy to clean.

Working principle of rotary dryer

The rotary drum dryer is mainly composed of inclined and rotating long cylinders. The dryer adopts the forward flow heating mode. Its heat source comes from the combustion device. Its combustion chamber and wet material feed are at the same end, and the hot air flow is consistent with the movement direction of the material. Because the dryer is inclined, the material flows to the rear end under the action of gravity and rotation. In the dryer, there are various types of plates with different staggered arrangement angles from front to back. On the other hand, the materials are repeatedly picked up by the plate, carried to the upper end and then continuously spread down, so that the materials form a uniform curtain in the cylinder, and fully exchange heat with the hot gas flow in the cylinder. Due to the repeated spreading of materials, the moisture contained in the dryer is gradually dried, so as to achieve the purpose of drying.
