May 13, 2019nbsp018332To apply what this means to your crusher, operations produce the exact sizes in the reduction process that their market demands. In the past, quarries produced a range of single-size aggregate products up to 40 mm in size. Still, the trend for highly specified aggregate means products are increasingly finer.
The production of aggregates involves a relatively simple process of surface mining, crushing, sizing and, frequently, washing which requires large volumes of fresh water. chemicals are not used in the processing of aggregates although minor quantities of a flocculent, or similar agent, may be used in removing sediments from process wash water.
We produce these materials from natural deposits such as granite, limestone and trap rock. our quarrying process typically begins with drilling and blasting the rock into smaller pieces. next, the material goes through various stages of crushing and screening to produce the sizes and specifications desired by our customers.
