Double rotor separator

Description

The double rotor separator is a new type of powder sorting equipment developed by our company. The powder sorting efficiency of the equipment can reach more than 85%-90%, the fineness adjustment is convenient and flexible, and the performance is stable and reliable.

Product structure

The double rotor separator is mainly composed of host, rotor, shell, air intake and transmission device. Its working principle is to use a high-speed rotating rotor to disperse the material, and rely on wind, static electricity, gravity and other physical properties to divide the material into different grades.

Performance Advantages

• 1. Simple structure: compact overall structure, easy maintenance, low failure rate.
• 2. Large processing capacity: with high processing capacity, it can meet the needs of large-scale production.
• 3. Good separation effect: The use of a number of separation technologies can achieve fine classification and precise control of materials.
• 4. Strong adaptability: can adapt to different material characteristics and production environment, widely used in various industries.
• 5. Easy operation: high degree of automation, simple and intuitive operation, easy to master.

Working Principle

1. The grinding material is fed into the separator at the upper inlet of the separator and falls onto the propeller spreader integrated with the rotor. Under the high-speed rotation of the spreader, the material is on the one hand scattered around by the action of inertial centrifugal force, and at the same time raised upward by the updraft generated by the blades of the propeller spreader. The material boiling is formed on the propeller blade of the discharge tray, and the finer particles in the material float upward and form a suspended dispersion state, while the coarser or heavier materials are dispersed along the wall of the cylinder by the discharge tray blade to complete a powder selection.

2. A lower cage rotor is arranged under the spreader plate. The lower cage rotor rotates with the main shaft to form a vortex air flow, which breaks up the heavier material falling along the wall of the cylinder again, and the fine powder in it is raised upward to return to the circulating wind and is graded again. The coarse powder is discharged from the inner cone by the eddy current device.

3. An upper cage rotor is arranged above the spreader plate. In the powder selection room, the air flow near the surface of the classification ring of the upper cage rotor and the material dispersed in the air flow are driven by the classification ring for high-speed rotation together with the classification ring, so that the material in the air flow is subjected to strong centrifugal force, the size of the force can be adjusted by the speed regulating motor to change the speed of the main shaft. When the speed increases, the force increases, at this time, if the treatment air volume is maintained, the cutting diameter will be reduced, and the product will be thinner; If the speed is reduced, the product becomes thicker. Therefore, the fineness of the product in the working process of the machine can be flexibly adjusted and controlled according to the specific process requirements, and the classification effect of the material particles is improved, and the efficiency of powder selection is improved.

4. The particles accelerated by the upper cage rotor enter each outer cyclone with the circulating wind. As the newly designed cyclone is equipped with a wind guide plate at the snail Angle of the intake duct and a speed control plate at the lower end of the cyclone sleeve, the fluid resistance of the cyclone is reduced. Under the action of the wind guide plate, the circulating wind enters the expanded part of the cyclone at a higher wind speed. The wind speed is suddenly reduced, the particle settlement is accelerated, and the dust collection efficiency of the cyclone is improved.

Question&Answer

Q:Why does gear thermoplastic deformation and gluing occur?

A:Reason: poor lubrication, less oil. High speed overload. Elimination method: clean the tank, change the oil and refuel. Control speed, control load or improve design.

Q:Why does the fan and the motor have two different axes?

A:Cause: The impeller is unbalanced. Fan inlet and outlet damper positions are incorrect. The foundation stiffness is not strong enough. Anchor bolts are loose. Fan impeller accumulates ash.
Elimination method: Correct the two axes concentric. Correct the balance. Adjust the damper position. Strengthen the foundation to increase stiffness. Check to tighten the bolts. After shutdown, open the service door to remove ash.
