Circular rotary disk centrifugal vibrating screening machine

Abstract

The invention discloses a circular rotary disk centrifugal vibrating screening machine which can carry out screening classification operation on materials. The circular rotary disk centrifugal vibrating screening machine mainly comprises a circular distribution disk which can rotate freely and annular screen cloth which can rotate freely and is fixed to an annular screen frame, vibrating motors are installed below the annular screen frame and are used for preventing the materials from blocking screen meshes and making the materials to jump, and damping springs are further installed below the annular screen frame and are used for preventing vibration from being transmitted to other parts. Through independent rotation of the annular distribution disk and independent rotation of the annular screen cloth, the materials which need to be screened to be classified evenly move towards the periphery of the circular distribution disk and the periphery of the annular screen cloth. In the movement process, because the diameter of the position, where the materials are located, on the annular screen cloth is larger and larger, a material layer is thinner and thinner, the distance and the time for fine particles with the size smaller than those of the meshes to reach the screen surface through a material layer composed of coarse particles are shortened, and the screening classification operation can be carried out easily.

Description

technical field [0001] The invention relates to a screening machine. This kind of screening machine can carry out efficient and energy-saving screening and grading operations for materials according to their particle size. Background technique [0002] At present, the known screening machines include fixed grid screens, cylindrical screens, roller screens, shaking screens, circular vibrating screens, linear vibrating screens, equal thickness screens, and resonance screens. But they all have some deficiencies more or less - low production capacity, low screening efficiency, easy to block the screen hole, low service life of the whole machine, high equipment manufacturing cost, excessive consumption of driving energy in the equipment Superior weight. Contents of the invention [0003] In order to solve the shortcomings of the current screening machinery, such as low production capacity, low screening efficiency, easy blockage of screen holes, low service life of the whole ...
