Am Cast Rocky Transformer

Am Cast, Inc. is proud to announce a revolutionary type of sand machine unlike anything available on today’s market. The “Rocky 600 V2 Transformer,” a reversible tertiary sand crusher, has been designed to transform all grain sizes, which are generally considered in aggregate production to be of “little interest,” into a commercially useable and valuable sand product. The Rocky can be fed with material ranging from 0-35 mm (0-1.375 in.) and transform this material into high value/ high yield (85-95 percent useable ASTM C-33 spec after one pass) sand product. This machine is capable of producing different types of sands used for ready-mixed concrete (ASTM C-33), self-compacting concrete, bituminous conglomerates, etc. The grain size of the sand is even programmable with an onboard motor inverter. Due to its innovative design, The Rocky promotes homogeneous wear on the impact surface of the hammers, which means less wear parts changes and longer crushing times.
