Chipping versus grinding for biofuel feedstock?

Friday 3 Feb 2012

 
Comminution is a critical process in biomass supply chains and can be conducted with either chippers or grinders. These machines use different work tools (knives and hammers, respectively) and are applied to different feedstock types, but few studies are available on the inherent differences between the two technologies.

A versatile grinder, alternatively equipped with hammers and knives, was studied to investigate the effect of tool type on machine productivity, fuel consumption, and product quality.

Three different feedstock types were processed and, depending on feedstock type, results showed the knife configuration was 30 to 80 percent more productive than the hammer configuration and required 15 to 30 percent less energy per unit of product.

Fuel consumption per dry ton was also 30 to 75% percent higher for the hammer configuration.
