Selection and Sizing of Secondary and Tertiary Cone Crushers

摘要

The selection of crushers for moderate to hard materials is the primary focus of this review. Factors affecting machine selection will be presented. Modern crushers have increased in size and performance. Requirements for today's crushers have evolved to a greater focus on the desired quality of the crushed product. Aggregate production today must meet more stringent shape and gradation requirements. In crush to leach applications, proper size reduction results in better recoveries. In mill feed preparation, the generation of fines and total top size reduction are key to maximum mill productivity. Proper understanding of a crusher's capabilities will minimize both installation and operating costs.
