grate WTE boiler should be enhanced by means of pre-shredding the MSW, thus reducing the average particle size, homogenizing the feed, and increasing its bulk density by an estimated 30%. Smaller particle sizes enhance reaction kinetics and flame propagation speed, due to the higher surface to volume ratio, and thus lower the amount

Fine Shredding of Municipal Solid Waste

Output material size in a horizontal type hammermill is controlled by the size of the openings of the grate. The grate is located across the output opening of the hammermill. Input material remains in the hammer- mill until it is small enough in at least two dimensions to fall through the grate openings.

Size Reduction - an overview | ScienceDirect Topics

Size reduction of lignocellulosic biomass is an important factor in any pretreatment process. Mechanical means can be used to reduce particle size sufficiently so that no further pretreatment is required prior to enzymatic hydrolysis, obviating usage of chemicals and associated concerns such as corrosion, recycling, neutralization and storage.

Intro to Size Reduction - Schutte Hammermill

Finished particle size is determined by a combination of the following: screen (or bar grate) size, shaft speed, hammer size, and hammer configuration. For example, a fast shaft speed, small screen and large number of hammers typically produces a fine end product. Conversely, a larger screen, fewer
