In the middle part of the 2010's, Superior launched an aggressive strategy to improve reliability and performance of the products serving the aggregate industry. Our customers — already buyers of conveyors — groaned for a better brand of service for their crushing, screening and washing equipment. Superior checked the boxes and made the leap.
Otherwise, three consecutive crushings are performed and the recycled coarse aggregate, fine aggregate, and powder materials are collected, respectively. The and concrete CD waste recycling process of "impact crusher + rolling crusher + hooproller grinder" is also capable of handling the concrete waste.

Coarse. Coarse aggregates consist of gravel, crushed stone or recycled concrete with particle sizes of ranging from 3/8inch to inches. Coarse aggregates are used in a wide range of construction appliions, notably in concrete and asphalt mixes. Common uses for coarse crushed stone. • Concrete aggregate.
Coarse aggregates (Fig. 52) consist of one or a comCHAPTER 5 Aggregates for Concrete bination of gravels or crushed stone with particles predominantly larger than 5 mm ( in.) and generally between mm and mm (3⁄ 8 in. and 11⁄ 2 in.). Some natural aggregate deposits, called pitrun gravel, consist of gravel and sand that can be readily used in concrete after minimal processing ...

· Crushing resistance of coarse aggregate is the key to the stability and durability of the skeleton structure of permeable asphalt (PA) mixture. To determine the technical requirements of crushing value of coarse aggregate used in PA mixture, steploading compression tests were conducted on the mixtures of PA13 and a control asphalt mixture AC13, respectively.
183 Aggregate crushing value test on coarse aggregates gives a relative measure of the resistance of an aggregate crushing under gradually applied compressive load. Coarse aggregate crushing value is the percentage by weight of the crushed material obtained when test aggregates are subjected to a specified load under standardized conditions.
