Abrasive screening machine allowing granularity to be adjustable

Abstract

The invention provides an abrasive screening machine allowing the granularity to be adjustable, and belongs to the technical field of machinery. The abrasive screening machine is characterized in that a fine sieve is located below a coarse sieve, and a conveying belt is located at the tail end of the fine sieve. Abrasive grains are selected through the coarse sieve, and the abrasive grains with the sizes being larger than required sizes are removed; the abrasive grains are selected through the fine sieve, the abrasive grains with the sizes being smaller than the required sizes are removed, and the abrasive grains with the sizes meeting requirements are selected; the abrasive grains are screened through the reverse conveying belt, cracked abrasive grains with poor circularity are removed, and plump abrasive grains with good circularity are selected under the action of gravity. The mesh number of the coarse sieve and the mesh number of the fine sieve of the screening machine can be changed according to requirements, the inclined angle of the coarse sieve and the inclined angle of the fine sieve can be adjusted according to different abrasive grains, and the inclined angle and conveying speed of the conveying belt can be adjusted according to different selection requirements. The abrasive screening machine achieves selection of the abrasive grains with the sizes and circularity meeting requirements, and is convenient to use, reliable and beneficial for improving screening quality and efficiency of the abrasive grains.

Description

technical field [0001] The invention belongs to the technical field of machinery and relates to a screening device for abrasive materials, in particular to a screening device for screening abrasive particles with uniform particle size and full particles. Background technique [0002] Abrasive particles are widely used in many fields such as polishing, abrasive jet processing, and material surface strengthening. The quality of products processed with abrasives is related to many factors such as the type of abrasive, abrasive particle size, and abrasive shape. The particle size and uniformity of abrasive particles It directly affects the stability of the processing effect, so the screening of abrasives is an essential link before abrasives are used. Now with the continuous emergence of new abrasives, the proportion of abrasives in the entire processing cost is also increasing. The recycling of abrasives can reduce processing costs, reduce environmental pollution, and improve t...

This mechanism uses wind pressure to remove impurities and broken particles, but when the size and quality of impurities and broken particles are similar to those of full-bodied seeds, it cannot be removed, and the use of wind pressure to screen will cause dust pollution
