Requirements on raw materials of sawdust pellet mill

The requirements on the raw material of sawdust pellet mill directly affects the quality of the sawdust pellets. Good control of raw materials can make high quality pellets. Then, what are the requirements for the raw material when making pellets with sawdust pellet mill?



1. Requirement on the size of raw materials.
When making pellets with sawdust pellet mill, the size of the raw material is required. Generally, the size of raw material after crushing must be less than 3mm, but the specific crushing size should be determined according to the expectations of the diameter of the pellet size and the aperture of die on sawdust pellet mill. Too large or too small of raw material after crushing would affect the yield and quality of sawdust pellets, even lead to no discharging of material.

2. Requirements on the moisture of raw materials.
There are strict requirements on the moisture of raw materials when making pellets with sawdust pellet mill. No matter what kind of raw material is used, the moisture must be controlled within 12-18%. If the moisture of raw material is too large or too small, the pellets would break or loose easily.

3. Completely get rid of the adhesive agent for raw materials.
There is no need to add any adhesive when making sawdust pellets, because the sawdust itself is a kind of crude fiber material with certain adhesive properties. It can be made into sawdust pellet through the extrusion of sawdust pellet mill. If the raw material you use has no adhesive properties, then don't worry about it. The vertical ring die sawdust pellet machine can help you to produce smooth pellets with large density due to the special structure of the equipment.

4. Different raw material can be mixed for granulating.
Sawdust pellet mill can not only use one kind of sawdust for granulating. It can also be mixed with other varieties of sawdust, such as the crop straw, nut shell, peanut shell, straw, etc. Pellet produced by sawdust mixed with other material still has high quality. While the pellet made of sawdust and straw is slightly lower, because the quality of straw itself is poor than the sawdust.

The content above is the basic situation of raw material of the sawdust pellet machine. In either cases, high quality pellet fuel can be produced as long as operating according to the requirement. If there are other problems, welcome to contact us.
