Wood is a all-purpose term used to portray any natural material which can be used as a fuel. For illustration wood, wood waste, energy crops and rural waste such as straw. A wood pellet mill has uneven features that make it achievable to process various biomass resources. For case in point the pellet mill have got to have adequate power to treat woody biomass, and also the capability to control features such as die velocity. At PelHeat we develop small mobile wood pellet mills to treat a wide range of biomass materials. The uses for these pellets could be as fuel, animal feed, animal bedding and still cooking pellets. A biomass pellet mill is a universal term to describe a pellet mill, however some pellet mills have specific features for handing out certain materials.

Grass pellet mills are used predominantly in the animal feed business. Grass pellet mills usually have a superior die speed than wood pellet mills for instance. Also power consumption is much lower, due to the reduced resistance of the grass. One of the key differences with wood pellet mills is the differentiation in die revolving speed. Wood has a much higher density than grass for example, and so is further difficult to deal with into pellets. Additional energy is required to process wood into pellets, as a result traditionally a lower gearing is required to condense the wood through the die. Also to gelatinise wood into pellets, higher construction temperatures are essential. Raw material temperature can be increased by processing the raw material through a steam conditioner. However another way to increase pellet quality is to increase resonance time through the die, hence a lower die rotation speed. Manufacture pellets is a process that relies on quite a few factors with regards to the raw material and the apparatus used.

The raw material must have a consistent moisture content, generally within the reach of 15%. The material must also be free from contaminates such as pebbles and metal, as these can cause serious damage to the apparatus. Pellet making equipment requires a high power input, usually requiring a three phase electrical supply. The center piece of equipment is obviously the pellet mill. Acceptable operation and maintenance of the pellet mill is the key factors in producing quality pellets efficiently. As stated there are quite a lot of variables which need to be prohibited to produce quality biomass pellets. Each raw material behaves differently in the pellet mill, and only by understanding the results can the procedure be adjusted to create suitable quality pellets. However many people concerned in how pellets are made, and possibly building their own set-up are not familiar with the details of the process.
