WSM’s Pre-Screens Help Reduce Energy Costs

Oregon-based West Salem Machinery’s (WSM) pre-screening technology can reduce energy and maintenance costs on grinding systems by 50 percent or more, according to the company.

A screen, installed before the grinder, removes acceptably sized material and any metal contamination prior to grinding. This decreases maintenance and power costs, and potentially reduces the size of the grinder. High-volume disc screens or vibrating screens are commonly used in this capacity. 

Typical applications include pre-screening of sawdust, shavings and fine wood from biomass fuel or pre-screening of mulch prior to entering the finish grinding system.

Screens are available with screening surfaces up to 6 feet wide and have a capacity of 5 to 500 tons per hour. WSM also offers custom portable units that operate on low 5 to 25 horsepower and provide reductions to grinding costs.
