The biomass pellet industry is evolving to become one of the fastest mounting alternative along with alternative energy forms. The biomass pellet equipment used to create pellet energy is similar to the apparatus used in the animal feed pellet industry which has existed for over a century. Yet there are significant differences in biomass pellet gear which will be discussed.

The process of biomass pellet manufacturing with biomass pellet equipments depends on the type of woody wood used. Some materials necessitate more size reduction, where extra need drying. At present the market leader in wood pellet fuel is the premium grade wood pellet fuel. Consumers prefer this energy owing to the fact that is produces a very low moisture content, in addition to therefore requires less maintenance. This type of biomass pellet energy is produced from the sawdust from timber processing. As the particle are already fairly small, the particles are just passed due to 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 example the moisture content can even be too low for the pellet to form effectively. Therefore water maybe introduced into the process. Alternatively by means of large scale production 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 plus also reduces load on the pellet mill and lowers fuel consumption. There are also specific differences a biomass pellet has over extra pellet mills.

Wood pellet apparatus is often known by more than a few dissimilar names. For case in point the biomass pellet mill is also known as a biomass pellet press. As described a wood 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 plus straws. These materials are much easier to compress into pellet form compared to wood. Because of the increased density of the biomass fibre, a biomass 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 biomass pellet apparatus. This produces the lower rotation speed in addition to much more torque to the pellet mill. As stated, premium grade wood pellets at present dominate the biomass pellet energy market, however there is only a limited number of resources suitable for premium pellets as well as the cost of the fuel is quite high. Lower grade biomass pellet fuel can provide an equal value of heat, on the other hand may generate a higher ash content. These pellets will be significantly cheaper though, as well as be able to use a wider range of woody wood resources. Not all biomass pellet stoves can burn lower grade wood pellets as well as extra biomass pellets. The design of the burn pot creating issues.
