West Salem Machinery Offers Two-Pass Grinding System

West Salem Machinery (WSM), Salem, Ore., has introduced its two-pass grinding system.

By employing this two-step system, larger size material can be converted with lower horsepower requirements and less energy use, according to a press release from the manufacturer.

The two-pass system combines a slow-speed, high-torque shredder and a high-speed vertical feed grinder. The high-torque shredder is the primary grinder used for the initial reduction of coarse material down to a 20- to 24-inch minus. The vertical grinder, or secondary grinder, then produces the finished product.

Pre-screening technology is another option available on the system. Adding pre-screening machinery between the primary shredder and the secondary grinder will remove acceptably sized material and metal contamination before entering the secondary grinder, saving on energy and maintenance costs.
