1. Chipping & Crushing:
IIn the wood pellet plant before raw materials are made into biomass pellets, they are first reduced into much smaller, uniformly-sized particles. When the thickness is larger than 10 mm or size is greater than 50*50 mm, a wood chipper is needed to chip these materials into smaller pieces. The hammermill is then used to further crush these small pieces into particles of less than 3 mm in diameter.
