Different pellets can be made from various biomass materials under certain favorable conditions. These conditions necessary for successful pelletizing is listed below.
- Moisture Content
The level of moisture in any given material plays a vital role concerning the performance of the material in the home use pellet mill. Moisture is required so as to produce pressure. The suitable content of moisture for making pellets should range between 12% and 18%. Too much or too little moisture will lead to the production of poor quality pellets. Also, the moisture level of the finished pellets should be maintained as low as possible so as to allow the pellets to burn efficiently.
- The Size of the Raw Material
The given raw material should be crushed using either a chipper, wood waste shredder, or a hammer mill depending on the raw material in question (build a small pellet plant). Research shows that the pellets which are made from raw materials that have been crushed have a consistent and better quality than the one that has not been crushed. However, the raw materials that are woody such as sawdust or wood chips then grinding process is skipped. It is important to note that any type of raw material must be reduced to a uniform and sufficient size to enable pelletizing. The milled material that is fed into the pellet mill must be smaller than the openings of the die holes of the small pellet mill. The suitable size required for pelletizing is 3mm to 5mm. There are various types of equipment used in size reduction are available, and they differ in their strengths and abilities. In some cases, only a single piece of equipment is needed while in others there is the need to combine the equipment so as to meet the required size.
Flat Die Pellet Mills Versus Round Die Pellet Mills
There are two different types of pellet mills available, and they include the round die pellet mills and the flat die pellet mills. Flat Die Pellet is superior in the following aspects.
- They are better for residential use or small scale production or home use.
- Their compact design and structure make them lightweight and small in size hence suitable for small feed pellet production such as make pellets at home or on farm.
- The flat die type is portable die and roller are fairly cheap as compared to those of the round die pellet mill.
- The flat die type are relatively easy to clean.
- Flat die pellets mills have a wider material tolerance. It is for this reason that the former are considered more robust when it comes to pelleting or processing problematic feedstock.
- The quick access to the pellet mills chamber allows for faster changing of the roller and die thereby enabling quick cleaning of the mills components.
Flat die design pellet mill allows for visibility i.e. viewing the material during the pellet process, enable one to see through the chamber during the pellet making process. Besides, others come with quick access doors to see into the chamber as the milling process goes on. For instance, if a certain material is producing pellets of low quality or even no pellets at all, it is possible to identify the reason behind such malfunction and a corrective action is sought immediately. The fact that one can monitor the pellet- making process directly allows for one to try several indeterminate raw materials to produce pellets thereby broadening his or her range of the available sources for making the pellet.
There are two different flat die pellet designs available in the market today and they include one with a rotating roller, and the other one has a rotating die.
Rotating die type Mill
This type of mill has an immobile roller with a rotating die. This, therefore, means that during the wood pelleting process the die rotates while the roller remains stationary. The roller does not move at all.
