aggregate particles, by size, within a given sample. In practice a known weight of material, the amount being determined by the largest size of aggregate, is placed upon the top of a group of nested sieves (the top sieve has the largest screen openings and the screen opening sizes decrease

Unlike other types of impact crushers, vertical shaft impact crushers (VSI) are designed with a unique rock-on-rock crushing principle, which significantly reduces the wear costs while offering superior cubical shape for the best quality fine aggregate produc-tion. VSI crushers are usually used in the final stages of the crushing process to shape

Aggregate material is separated into sizes through the use of screens. In most crushed-stone operations, this process occurs after the shotrock has been processed by a primary crusher. The role of screening in the processing flow is to size and separate material ahead of secondary and tertiary crushing circuits, and/or to size and separate ...
