The biomass pellet industry is evolving to become one of the fastest rising renewable as well as renewable fuel forms. The wood pellet apparatus used to manufacture pellet fuel is similar to the equipment used in the animal feed pellet industry which has existed for over a century. Though there are significant differences in wood pellet tools which will be discussed.

The process of wood pellet manufacturing by wood pellet equipments depends on the type of woody wood used. Some materials need more size reduction, where other require drying. At this time the market leader in wood pellet energy is the premium grade biomass pellet energy. Consumers prefer this energy through the fact that is produces a very low moisture content, and therefore requires less maintenance. This type of wood pellet energy is created from the sawdust from timber processing. As the particle are already fairly small, the particles are just passed through a hammer mill to guarantee a uniform particle size for the pellet mill. If the sawdust is from kiln dried timber, drying is not required. In this instance the moisture content can even be too low for the pellet to form effectively. Therefore water maybe introduced into the process. Alternatively with large scale construction steam conditioning is used to released the untreated lignin to aid pellet binding. High heat steam is used in the conditioner prior to the pellet mill. As the matter enters the pellet mill the matter is pre-heated. This aids pellet quality and also reduces load on the pellet mill and lowers fuel consumption. There are also precise differences a wood pellet has over extra pellet mills.

Wood pellet tools is often known by means of more than a few dissimilar names. For case the biomass pellet mill is also known as a biomass pellet press. As described a biomass pellet press has precise differences when compared to an animal feed pellet mill. Firstly one of the most important differences is the speed at which the gear operates. Animal feed pellet mills process low density materials such as grasses along with straws. These materials are much easier to compress into pellet form compared to wood. Owing to the increased density of the wood fibre, a wood pellet press operated at a much lower speed than an animal feed pellet mill, generally half the speed. This is achieved owing to a much lower gearing of the wood pellet gear. This produces the lower rotation speed and much more torque to the pellet mill. As stated, premium grade wood pellets currently dominate the wood pellet energy market, however there is only a limited number of resources suitable for premium pellets along with the charge of the fuel is quite high. Lower grade biomass pellet energy can provide an equal value of heat, though may generate a higher ash content. These pellets will be significantly cheaper on the other hand, and be able to use a wider collection of woody biomass resources. Not all wood pellet stoves can burn lower grade wood pellets plus other biomass pellets. The design of the burn pot creating issues.
