Rich pickings at the Roual Welsh

摘要

CE Projects' Evolution 500 separator is designed to handle the slurry produced by up to 90 cows or 1,600 pigs. Described by the company as being the "baby" in a range of three sizes, it can be powered by a single-or three-phase electric motor and, like its larger siblings, can be set to operate at programmed intervals. Separation is achieved by passing the slurry between a hard rubber roller and a screen. The latter has brushes to keep it clear and there is also a stone trap.
