Hammer Mill

Hammer mill can grind wood chips, small branches, bamboo shavings, straw, stalk, and many other biomass wastes into 3-5mm long, so that such materials can be fed into the pellet mills for pelletizing, or into briquette machines for briquette making.

There are 2 kinds of hammer mills: small hammer mill used with small pellet mill; large hammer mill used with large pellet mill.

It is almost the most indispensable part for biomass pellet making.
