The Complex Movement of Materials in the Classifying System

Henan Hongxing Mining Machinery Co., Ltd.

The classifier is a new type of separating equipment combining the crushing of materials and the separation. Its crushing principle is by use of centrifugal impact.

The shape of materials after the crushing of roller crusher is like a cake.

Those cake-shaped materials are fed evenly from the symmetrical feeding port continuously and fall on the crushing plate with hammer-shaped protruding arises.

The crushing plate is rotating in the high speed driven by the main bearing, making the cake fall on the scattered disk, which is accelerated and part of the role of the liner hammer-shaped rib from the scattered disk.

The cake-shaped materials are thrown along the scattered disk tangent direction after crushing counterattack lining.

Since the crushing process of the material is continuous, bounced back from a counterattack lining materials will be again severely impacted by high-speed flying out materials from the scattered disk.

It must be emphasized that the role of the hammer-shaped ridge on the surface of the scattered disk lining is different from the traditional hammer of hammer crusher, and its main role is to avoid the material in the scattered disk surface slipping along the scattered disc circumferential direction of acceleration.

When thrown from the scattered disc with a higher initial velocity, obtaining a larger kinetic energy, materials will forcefully impact along the scattered disc periphery to the arrangement of counter liner for strengthening of the impact of the cake crushing effect.

The scattered materials fall into the classifying area through the annular channel.


The crushed materials enter into the separating area through the circular passage around the stopping cone under the direction of it.

The classification of materials is the use of inertia force and aerodynamics.

The course raw materials have a large moving inertia, their transformation of moving state in the wind separating area is much small, so they can fall into the cone cylinder and be returned through discharging port, and go into the weighting cylinder above the roller crusher together with new materials.

The inertia force of fine materials is much smaller, so their moving state will change greatly in the wind separating area, and they will fall between the inner cone cylinder and outer cone cylinder, and be transferred to ball mill to have further grinding process or directly transferred to classifier to separate final products. http://vibratingscreenhongxing.wordpress.com/
