I. product features

1. Advanced sorting principle

Breaking through the traditional technological principle of washed sand and stone separation, the flow field of materials is optimized by using a variety of grading systems and aero aerodynamics analysis method according to the characteristics of sand and stone industry, so that the operation resistance of equipment is significantly reduced, separation efficiency is improved, and energy saving and consumption reduction is very obvious.

2. Higher classification accuracy

The "eddy current rectifier", which is patented by the state, is used in the classifier. The airflow in the rectifier rises relative to the rotor but does not rotate, and the driving power and system wear are significantly reduced. Materials are repeatedly cleaned in the precinct for higher and more accurate classification.

3. Easy operation

The classifier adopts frequency converter stepless speed regulation, the quality adjustment is convenient, sensitive and reliable and the adjustment range is wide.

4. High classification efficiency

According to the physical and chemical properties of sand and gravel, the range of lifting zone of grading zone is increased to make the material more thoroughly dispersed so as to ensure the grading efficiency.

5. Wear-resistant design is maintenance-free

The main parts of the separator are as follows: disperser, fine material collector, side air regulating board, main air regulating board, multi-channel distributor and other main parts. It is made of imported wear-resisting steel plate, wear-resisting ceramics and boiler steel, which effectively improves the service life. The whole machine has been dynamic balance correction, running smoothly in the range of full speed.

6. The system adopts dual interlock air valve and internal circulation air to effectively reduce air leakage of the system and dust emission pollution in operation.

Ii. Technical parameters

Iii. Working principle

In working status, high-speed motor through the transmission device drives the vertical shaft turn, the material through the classifier of the upper chamber inlet into the powder room, then by setting the coarse powder collecting cone fluctuation between the cone and powder fall in material plate, pipe and materials plate with the vertical shaft turn, material under the effect of inertial centrifugal force, to evenly around the dispersed materials in external fan through the inlet into the powder chamber under the action of high-speed airflow, the material of heavy particles under the effect of inertial centrifugal force is flung to the selected powder inside wall of the chamber. After the collision, the lost kinetic energy slides down the wall and falls into the coarse powder collecting cone. The rest of the particles are picked up by the rotating and rising air flow. When passing through the action area of the strong wind blade, some coarse powder particles are thrown into the inner wall of the powder selection chamber under the impact of the strong wind blade.

After passing through the high wind blade, medium coarse powder and fine powder continue to rise through the vertical guide blade and enter the secondary powder selection area under the action of updraft. Under the action of the strong and stable plane eddy current formed by the rotating cage rotor, the dust-containing airflow makes the medium and coarse powder lose kinetic energy after being thrown to the vertical guide blade under the action of centrifugal force, fall into the cone of medium and coarse powder collection and discharge through the medium and coarse powder tube. The fine powder that meets the requirements passes through the cage rotor and enters into the inner part of the rotor. It goes into the efficient and low-resistance cyclone separator with the circulating wind and then slides into the fine powder collection cone and becomes the finished product.
