Product introduction
Working Principle
1、Materials from the upper part of the powder selector hopper into the powder selector inner shell, falling into the rotor and rotor into one of the spinning paddle spreading disk, under the high-speed rotation of the spreading disk, the material on the one hand by the inertial centrifugal force to the surrounding scattered, while by the spiral spreading disk blades produced by the rising airflow upward, in the spreading disk propeller blade to form the material boiling. The finer particles in the material float upward and are suspended and dispersed, while the coarser or heavier material is dispersed by the spreading disk blades and falls down along the cylinder wall, completing the sub-selected powder.
2. There is a lower cage rotor under the spreading disk, and the lower cage rotor rotates with the main shaft to form a vortex airflow, which will disperse the coarse and heavy materials falling along the cylinder wall again, in which the fine powder is lifted upward and returns to the circulating wind to be graded again. The coarse powder is discharged from the inner cone through the dripping device.
3. There is an upper cage rotor above the spreading disk. In the powder selecting room, the airflow near the surface of the upper cage rotor grading circle and the material dispersed in the airflow in the grading circle driven by the grading circle with the grading circle for high-speed transit, so that the material in the airflow is subjected to strong centrifugal force, the magnitude of the force can be adjusted by the speed motor to change the rotational speed of the spindle. When the rotational speed is increased, if the air volume is kept constant, the cutting size will be reduced and the product will become fine; if the rotational speed is reduced, the product will become coarse. Therefore, the fineness of the product in the working process of this machine can be flexibly adjusted and controlled according to the specific requirements of the process, and improve the grading effect of the material, improve the efficiency of powder selection.
4, after centrifugal acceleration by the upper cage rotor particles with the circulating wind into the external cyclone barrel, due to the new design of the cyclone in the air inlet snail angle with a wind guide plate, in the lower end of the cyclone barrel sleeve additional speed plate, so that the cyclone barrel of the fluid resistance down, the circulating wind in the role of the wind guide plate, with a higher wind speed into the cyclone barrel, because of the expansion of the part of the snail angle, so the wind speed is suddenly reduced to accelerate the particles settle! The wind speed is suddenly reduced due to the expansion of the snail angle, which accelerates the particle settling and improves the dust collecting efficiency of the cyclone.
Structural characteristics
Compared with the traditional grading machine, gravel classifier has the following unique features.
1、Sand grader adopts propeller spreading disk. It has the function of material spreading, but also produces the rising airflow to spread the material particles on the surface of the leaf boiling up and dispersed state, which can make the material particles increase the grading and dispersing performance.
2, grading principle of science, gravity grading and centrifugal grading double grading force field, materials in the grading chamber, in the strong cyclone and tangential shear effect, material dispersion and grading intensity is high, grading efficiency is high, the grading of the materials are graded by the grading interface is clear in the selection of powder area, each part of the selection of the powder conditions are stable and unchanged, so the grading precision is high.
3、Using the lower cage rotor, it can help the accumulated material particles to be lifted up again, increase the polarization ability, and effectively reduce the content of fine powder in the coarse powder.
4、Adopting speed control motor to adjust the spindle speed, the fineness adjustment is convenient, sensitive and reliable, and the adjustment range is wide.
5、Optimized design of the powder selecting area and the space range of the lifting area, which improves the powder selecting efficiency.
6, the new design of the cyclone inlet snail angle, add a wind guide plate, the newly developed cyclone sleeve structure, so that the fluid resistance is reduced, improve the cyclone dust collection efficiency.
7, in the machine optimized design of a variety of anti-condensation devices, anti-condensation effect is good.
8, in all easy to wear parts, are used in new wear-resistant liner protection, maintenance is simple and convenient, effectively extend the service life of the host.
