Problems solved by technology

[0007] The uniformity of the above-mentioned background technology neither solves the phenomenon of screen resonance, nor solves the phenomenon of stone blocking the screen holes; second, it neither solves the physical hazards of dust to operators, nor solves the problem of environmental pollution caused by powder method The third is that neither the recycling of tailings materials nor the multi-stage sorting and production of stone materials have been realized; the fourth is that it is impossible to produce in rainy days, and it is necessary to ensure the dryness of stone materials. The production conditions are restricted by the climate, and it is impossible to Realize all-weather open-air production

Abstract

The invention relates to a special blowing device and a special blowing method for dry sand grinding and dust removing complete equipment, which can effectively prevent stone materials from blocking a sieve and can also effectively improve sieving efficiency. Many rows of air tubes in the air blowing device are divided into two or more than two groups, the number of the air tubes in each group is two or more than two, and the air inlets of the air tubes in each group are communicated and controlled to blow air or not and blow air circularly or crosswise by a control valve of a time controller or a program controller. The blowing device and the blowing method have the advantages of preventing the stone materials from blocking the sieve, prolonging the service life of the sieve and effectively improving sieving efficiency of the sieve and featuring novel structure design, uniqueness, simplicity and practicability.
