The research on new sand making technology and its features

The present sand making technologies mainly include two types: tertiary crushing and rod mill combination sand making technology and vertical shaft impact crusher sand making technology. These two sand making methods have both advantages and disadvantages. Given this, the researchers propose the argument that users only use vertical shaft impact crusher to grind the hard rocks into sand, and through the optimization and adjustment of traditional sand making machine technology reasonable selection of vertical shaft crushing equipment, finally reach the goal of producing qualified sand. This article will give a detailed introduction to the research on the new sand making technology and its features.

As for the artificial sand and stone material production system that is used for processing light and high corrosive parent rocks, the main disadvantages of only using vertical shaft impact crusher to manufacture sand lie in uneven product grading and high fineness modulus of the final sand. If the customers want to properly reduce the fineness modulus of the sand in order to satisfy the project requirement, they only need to properly reduce the average diameter of the sand. According to traditional sand making technology, the new technology makes the following adjustment: the part of coarse sands whose particle granularity ranges from 5mm to 2.5mm are recrushed through the fineness modulus adjusting cabin and the vertical shaft impact crusher rotating with high speed, thus reaching the goal of adjusting the fineness modulus and grading of the final products. As for the selection of crushing equipment, it is for the best to choose the stone impacting stone series vertical shaft impact crusher which adopts the material impacting material crushing principle, thus significantly reducing the abrasion of the equipment caused by the rocks.

(1) This sand making technology is suitable for hard rock with high impacting strength, corrosion and compression strength.

(2) The keys to the new technology are three. Sand making technology: change the rod mill to crushing machine, thus reducing energy consumption and civil engineering; the selection of crushing equipment: mainly choose the stone-impacting-stone vertical shaft impact crusher to reduce the abrasion of the equipment caused by the hard rocks; the fineness modulus adjusting cabin adjusts the fineness modulus of the final sand.

This new sand making technology can not only satisfy the quality requirement of sand, but simplify the sand making process, effectively improve the disadvantages of traditional sand making technology and significantly improve the sand making efficiency, so that it is the development direction of sand making technology in the future.
