The V-shaped powder selector disperses the cake material coming out of the roller press, and then separates the qualified fine powder from the dispersed material, which is beneficial for the smooth operation of the roller press, improves the system output, and has a drying function.

Powder selection machine user installation site

The material is fed into the upper feeding port to form a material curtain, and the incoming airflow passes through the material curtain from the inlet and comes into contact with the material. In the powder selection area, the stepped inclined baffle plates installed on the inlet and outlet sides of the selected powder machine are used for dispersion.

The materials collide back and forth at the ends of the baffle plates on both sides, achieving the effect of breaking up the material blocks, fully exposing the fine powder, and prolonging the residence time of the material curtain in the powder selection area. The coarse material is discharged along the guide plate, and the gas carrying the material is discharged from the exhaust outlet and enters the powder sorting machine for sorting, separating the material and gas. The baffle plays a role in guiding and directing materials. This type of powder selection machine relies on wind power to improve, transport, and grade with high accuracy.

There are no rotating parts inside, mainly composed of grid plates arranged in a ladder shape. The materials to be sorted flow in a trapezoidal shape on a set of steps, and there is sorting airflow passing through the steps. The airflow separates fine powder from the material and transports it to the fine powder outlet. By adjusting the sorting airflow, the particle size distribution and flow rate of coarse and fine powder can be adjusted. Improved the stability of the powder selection machine, and the structure of the powder selection machine is simple, easy to install and maintain, with minimal wear and maintenance.
