There are several essential tools that every efficient pellet mill needs. With the equipment, the output of pellet mills can be greatly improved and maintained. On top of this list is a hammer mill. This mill is most useful in making sure wood chips are broken down into a size pellet mills can easily compress into pellets. In some instances wood chips that make up the primary biomass used to manufacture pellets come in a large size that complicates the whole process pelletizing a lot more complicated. Large pieces of wood make it impossible to come up with compact pellets.
Massive mechanical pressure is required to make quality wood pellets. Massive compression forces are required to make pellets compact with enough binding force to hold them together. You can therefore see that particle size here is a matter of concern. Big particles will not bond well together with smaller particles. Uniformity here is a highly regarded factor. So a pellet maker will need a solution that will ensure that the biomass used in pelletizing. A wood chipper might look like the best solution here, but it wood chippers are not particularly known for their uniformity.
A hammer mill on the other hand has a scalable fitting that allows you to adjust the size of the particles you want produced. If you are using wood shavings or straws as your biomass, you can set a 6mm screen setting on your hammer mill so that large wood chunks or straws can be milled down to pass through the screen. To make sure that the final biomass will produce high quality pellets, then you can mix wood shavings, straws and grass in the hammer grinder to get a compound mixture of all the ingredients. This increases the cohesion forces between the materials and once the biomass is pelletized, the resulting pellet is both durable and easy to store.
However, you have to ensure that the biomass is dried thoroughly well before it is pelletized. Even after using a hammer grinder, it is important to dry the biomass to prevent the pellets from crumbling once pelletizing process is complete.
