From powder to pellets
An agglomeration equipment and systems supplier designs a new building and processing line to pelletize and package a company's powdered limestone.
Stuart M. Perry Inc. operates a limestone mine, limestone plant, and asphalt plant at its Berryville, Va., site. The company provides crushed limestone aggregate for road construction and building foundations, powdered limestone for use as an agricultural fertilizer, and asphalt for roads, parking lots, and driveways. The company's grinding facility produces the powdered limestone, which is sold in bulk for application to agricultural fields. The company recently automated the grinding operation and began producing a surplus of powdered limestone, which is dusty, difficult to handle, and relatively valueless. To reduce the dust and increase the limestone's handling ease and value, the company worked with an agglomeration equipment and systems supplier to design a new building and processing line to pelletize and package the powdered limestone. It could sell this product directly to consumers for lawn and garden applications.
