Product Overview


Separator
In cement industry production, in order to improve the efficiency of the grinding system and reduce the energy consumption of the product, the circle flow grinding system is now widely used. As an important part of the system, the stability of the performance of the separator directly affects the working efficiency of the system.

LaFa series separator applies the plane vortex theory to the cyclone separator, and is a new type of separator developed by itself. It has been proved that the powder selection efficiency reaches 85-90%, and the fineness adjustment is convenient and flexible, and the performance is stable and reliable.

Compared withthe traditional separator, LaFa‘s separator has the following unique advantages:
1. It adopts a detachable combined propeller
scattering plate. It not only has the function of spreading, but also generates an upward airflow to make the material particles on the blade surface of the scattering plate boil and disperse, which can increase the classification and dispersion performance of the material particles.
2. Advanced classification principle. Combining multiple powder selection mechanisms, using the balance
of opposite centrifugal force and centripetal suction of airflow, the material passes through the classification interface and powder selection area clearly, so the classification accuracy is high.
3. The lower cage rotor connected in series can lift and scatter the coarse powder particles separated by the upper powder selection chamber, further separate qualified fine powder, and ensure the uniformity of the vortex airflow in the machine.
4. The main shaft of the powder selection machine adopts stepless high speed, convenient fineness adjustment, sensitive and reliable, and wide adjustment range.
5. The powder selection area is re-optimized and designed, and the spatial range of the lifting area is improved to improve the powder selection efficiency. 6.The low-resistance cyclone dust collector is adopted, and the equipment resistance is low and the dust collection efficiency is high.
7. A variety of anti-condensation devices such as elastic sweepers are optimized and designed in the machine, and the
anti-condensation effect is good.
8. In all vulnerable parts, new multi-stage lining protection is adopted, which effectively extends the life of the main machine.
9. The rotation system adopts a dry oil workstation system to successfully solve the problem of bearing wear.
10. The use of super-static structure makes the whole machine basically vibration-free; the use of dust-proof and
vibration-reducing fans reduces system vibration.
11. The coarse powder pipe and fine powder pipe adopt double interlocking air valves, which greatly reduces the air leakage rate and overcomes the defect of large dust in the previous powder selection machine.


Working Principle


1. The material discharged from the mill enters the inner shell of the separator from the upper hopper of the separator, falls on the combined propeller scattering plate integrated with the rotor, and is scattered around under the high-speed rotation of the scattering plate. At the same time, it is lifted upward by the rising airflow generated by the propeller scattering plate blades, and the material boils on the propeller blades of the scattering plate. The finer particles in the material float upward and are suspended and dispersed, while the coarser or heavier materials are dispersed by the scattering plate blades and fall along the cylinder wall to complete the powder selection.
2. A lower cage rotor is provided below the scattering plate. The lower cage rotor rotates with the main shaft to form a vortex, which breaks up the coarse and heavy materials falling along the cylinder wall again, and the fine powder in it is lifted upward and returned to the circulating air for classification again. The coarse powder is discharged from the inner cone through the drip device.
3. A cage rotor is provided above the scattering plate. In the powder selection chamber, the airflow near the surface of the upper cage rotor classification circle and the materials dispersed in the airflow rotate at high speed with the classification circle under the drive of the classification circle, and thunder at high speed together with the classification circle, forming a uniform and strong vortex airflow around the classification circle. In this area, the relationship between the centrifugal force and the suction force at any position is constant, and the centrifugal force on the material in the airflow can be adjusted by adjusting the speed of the motor spindle. When the speed increases, the force also increases. At this time, if the air volume is kept constant, the cutting particle size decreases and the product becomes finer; if the speed decreases, the product becomes coarser.
4. After classification by the upper cage rotor, the fine particles enter the external cyclone dust collectors with the circulating wind. Because the newly designed cyclone dust collector has an additional air guide plate at the air inlet, a reflective screen is added to the inner cone, and a deceleration plate is added at the lower end, the fluid resistance of the cyclone dust collector is greatly reduced. Under the action of the air guide plate, the circulating air enters the cyclone collector at a higher wind speed. The wind speed suddenly decreases in the expanded part of the snail horn, which accelerates the sedimentation of particles and also improves the dust collection efficiency of the cyclone dust collector.
