Those fortunate enough to be mining white rock for manufacturing sand know its value in the marketplace. There are others, however, who have access to such rock but do not have the knowledge to process it cost-effectively into sand. Needless to say, there is little to no incentive to make sand if it is not profitable. So cost-effectiveness is key. Some sand-production companies have taken a significant step by turning pea gravel that had no resale value into sand products that command a premium price.
A major change has been made to the sand producing plant by our VSI crusher. Before the VSI crusher addition, salable sand was limited to 75 percent of all the materials mined. The rest of the stone was classified as pea gravel (oversize) so it was stored in great mounds with no marketable use for it.
VSI sand making machine (also named VSI vertical shaft impact crusher) is newly developed equipment, based on our engineers’ rich experience, absorbing the advanced technique overseas, with international advanced stage. It is widely used in all kinds of minerals, cement, refractory material, carborundum grain, glass raw material, construction sand, stone stock and all kinds of metallurgy slag.
