Stones are air classified according to size or density. Air classification provides the most effective means for separating a product from a feed stream, for dedusting, or when used in conjunction with grinding equipment for increasing productivity.

Stones can be reduced in particle size with Sturtevant’s crushers. The crushers are best-suited for controlling the reduction of friable materials to granules where fines are undesirable. Crushers also reduce particle size for fine grinding to coarse crushing capabilities.

Many natural deposits including limestone, granite, trap rock and other durable mineral resources can result in crushed stone.
