Because of the violent collision and some soil content on raw material, the final sand will always contain some rock powder and soil powder when vertical shaft impact crusher is used to process raw material. The soil powder will greatly damage the gradation of sand. However the rock powder is very important for final sand’s application, especially it can compensate the shortcomings that the mechanism sand results a big gap, big requirement and poor movement on forming concrete.

So how to get rid of soil powder and keep rock powder of the final sand is a critical problem during mechanism sand field.

Sand washing machine’s coming makes the problem disappear but it needs a lot of water. So the mechanism sand making line is usually in the site around river or other areas with big water resource.

Is it possible for investors to start sand making line without water at working site? At least, KEFID will say Yes to you.

According to many years’ research on sand making machine and grinding machine, as well as to the characteristics of mechanism sand and visiting some working site, the engineers from KEFID machinery discover that the soil powder can be separated from final sand but keep the rock powder available at the same time without water, which make final products more superior and well-recognized. During the new craft, the sand washing machine is replaced by separator, so the water is useless but getting the same effect.
