What are the Requirements for Raw Materials When Making Wood Pellets?
When wood pellet machine produce pellets, the general size of the crushed raw material must be less than 5 mm, the specific size of the crushing fineness depends on the size of the pellets and the hole diameter of die mold. Raw material crushed too small or too big will affect the production yield and quality.
To make wood pellets, the water content is also a strict requirement. No matter what kind of raw materials it is, water must be controlled within 12-18%. If the water content is too high or too low, the particles will easily break .
There is no need to add any binder when making sawdust wood pellets, because the sawdust itself is a kind of crude- fiber material with a certain degree of adhesion. So through the wood pellet machine pressing process, it will be able to be naturally shaped. Do not be afraid if you use non-adhesive raw materials, our exclusive ring die sawdust pellet machine produced by Henan Yearmega Industry Co.,Ltd can help you. Due to the special structure, this sawdust wood pellet machine can generate strong pressure, which could process different kinds of materials, solving the problem of non-adhesive raw materials shaping. And Yearmega sawdust wood pellet machine could make pellets with high density and surface of pellets are very smooth.
The Yearmega wood pellet mill does not just granulate with one kind of wood material, but it can also granulate mixed materials together. For example, wood chips could also be incorporated into crop stalks, nutshell, peanut shells, straw and so on.
Sometimes raw materials will become moldy and black if we are not able to process in a short time. If we use this kind of materials, the pellets would not reach to the required high density and heat. What a pity if we throw away the moldy materials! There are one solution. As long as we incorporate more than 50% of fresh raw materials on it, it will be no problem. The more the new raw materials incorporated together, the better pellets we could make by our Yearmega wood pellet machine.
