A novel MSW shredder was presented but many aspects of the shredder have not been fully characterized. The feed moisture is an important factor that influences crushing performance. This paper focuses on the effect of feed moisture. The breakage of municipal solid waste (MSW) at several moisture levels (0%, 10%, 20%, 40% and 60%) was conducted with a laboratory shredder to investigate the effect of feed moisture on product size distribution and specific energy consumption under two different hydraulic pressures (40 and 60kg/cm²). The results showed definite effects of feed moisture on the product size distribution and specific energy consumption: there is a tendency for the fine production in products to decrease with increasing amounts of water content in the feed; with the increasing feed moisture, specific energy shows an increasing trend; the specific energy and product size distribution under lower hydraulic pressure is more sensitive to the feed moisture than it is under higher hydraulic pressure.
