AmCast Inc., Bohemia, N.Y., has announced the Rocky Transformer, its first line of capital equipment in the form of a sand mill, which is designed to transform 97 percent of unwanted crusher byproduct into a finished sand aggregate.

The machine accomplishes the transformation by using two rotors mounted horizontally within the crushing chambers, spinning in opposite directions, which enables a 100 percent impact crushing process. Capable of handling aggregates up to an inch and a half, the Rocky yields 97 percent useable sand in a single pass. The Rocky plant is available in a stationary unit or as a transportable, self-contained version. The self-contained unit comes equipped with all necessary conveyor systems, a motor inverter to adjust the RPM and sand output and cost accounting features accessible through the onboard Windows-based computer system.

Vinnie Rocco, Am Cast’s general manager, sees the need for this machine from both an economical aspect and as a green initiative. “In today’s ever-growing global industry, conservation has long been a topic of discussion. With many of Earth’s non-renewable resources in the cross hairs, mining and construction companies worldwide have been collaborating on ways to reduce the negative impacts of global industry,” Rocco says.

The machine has been put to use for an aggregate producer located in Colorado. Rocco points out that one Am Cast client has begun using Rocky instead of their Sandvik open table VSI crusher. Rocco continues, “With approximately one million tons of unwanted quarter inch, minus alluvial deposit from the Platte River to crush, the Rocky Transformer will have its work cut out. The quarry foreman told us that if they had put inch and a quarter material into their VSI crusher, they would have gotten the same size output with more dust. That tells you how effective Rocky is.”

Rocco adds that there is interest in the United States, Canada and South America. “From concrete sand, bunker sand for golf courses, and even Aglime, there is endless potential for what Rocky can do. The most appealing part is that all of these sand products can be created from otherwise undesirable stockpiles of material.”
