The V-type classifier disintegrates the cake-like material exiting the roller press, separating out the qualified fine powder from the disintegrated material, which benefits the smooth operation of the roller press, increases the system yield, and features drying capabilities.

Material is fed into the machine through the upper feeding port, forming a material curtain. The incoming air flow passes through the curtain, coming into contact with the material. In the selection zone, the material is dispersed by the stepped inclined baffle plates set on the inlet and outlet sides of the classifier.

Material collides back and forth at the ends of the baffle plates, achieving the effect of breaking up material blocks, fully exposing fine powder, and extending the residence time of the material curtain in the selection zone. Coarse material falls and is discharged along the guide plate, while the material gas is exhausted through the exhaust port and enters the separator for sorting, separating the material from the gas. The baffle plates serve the functions of guiding airflow and material. This type of separator relies on wind force for lifting, conveying, and achieving high grading precision.

The separator features no rotating parts, primarily composed of a ladder-shaped grid. The materials to be sorted flow in a trapezoidal pattern onto a series of steps. A sorting air flow passes through the steps, separating fine powder from the material and directing it to the fine powder outlet. Adjusting the sorting air flow allows for regulation of the particle size distribution and flow rate of the coarse and fine powders. This improves the separator's stability, and its simple structure ensures easy installation and maintenance with minimal wear and reduced repair needs.
