Pelletizer and Pelletizing

Pelletizing is a process where a pelletizer is used to reduce the volume and increase the density of a raw material. Many different raw materials can be processed in a pelletizer, for various different purposes and uses. For example the pelletizing of animal feed has become very wide spread, due to the advantages of precise feed formulas, and better storage and rationing.

The wood pelletizing industry over recent years has continued to grow, and will continue into the future. Wood pellet heating is a convenient, low maintenance means to utilize a low carbon fuel to replace existing gas and oil heating systems.

Pellets

Pellets are a compressed for of the original raw material, the raw material in question can be almost any organic matter. Pellets have a uniform shape, size and density. The density of a pellet is far higher than the original raw material. This is one of the key advantages of of pellets, in terms of increased energy density, lower transport costs and smaller storage space.

Biomass

Biomass is any cellulose organic matter which can be used as a fuel source. Biomass includes wood and wood waste, grasses and straws and other energy crops such as hemp. Almost all biomass materials can be processed via a pelletizer into pellets. In terms of pelletizing biomass, each biomass material has different characteristics. Some biomass materials can produce pellets without the need for additional binders. However for some biomass, binders are required to produce pellets of sufficient quality and density.

Also not all biomass pellets have the same combustion characteristics. Wood pellets in general produce little ash and no clinker formations, however this is not true of all biomass pellets. Also some biomass pellets are corrosive. Please visit the Pellet Stove Guide to find out more.

Pelletizing Production Guide

At PelHeat we develop small scale mobile pelletizers. To aid general knowledge of the pellet production process we have developed this guide. The guide covers the pelletizing process in a simple ten step process, through raw material material preparation and pellet compression.
