Material screening method

Abstract

The invention relates to a material screening method. Materials are guided out into a feeding port of a vibration bin of a screening machine; a vibration motor is started, so that a separation rod anda fixing rod of a separation plate are staggered and are in a whole plate shape to bear the materials; after the separation plate rotates to the inclined position, the light materials are guided outto a second conveying belt and guided out; after the separation plate rotates to the lower front end and rotates to the lower position, a separation mechanism is started, a separation rod is made to deflect, the separation rod and the fixing rod are made to be in the coincident state, and heavy materials are led out of a gap of the separation rod into a first conveying belt and led out; when the separation plate rotates to the position away from the first conveying belt, the separation mechanism stops, the separation rod and the fixing rod of the separation plate are staggered and are in the whole plate shape so as to bear materials at the position of the feeding port of the vibration bin, and by means of the method, separation of the materials can be effectively achieved, and further treatment is facilitated.

Description

technical field [0001] The invention relates to the technical field of material processing, in particular to a material screening method. Background technique [0002] When screening materials with different qualities, vibratory screening or winnowing can be used multiple times to screen materials with different densities. For example, in garbage sorting operations, materials are first crushed and then crushed , it is necessary to separate the light flake or block material from the heavy material in order to carry out the next processing operation. Most of the existing screening equipment is a drum structure, and the screening efficiency is low, and Most of them are air separation equipment, which makes it difficult to collect the screened materials. Contents of the invention [0003] The purpose of the present invention is to provide a material screening method, which can effectively realize the sorting of materials to facilitate further processing. [0004] The technic...
