On the PelHeat website we promote a range of small pellet mills which can be used in the house. These pellet mill are of a high quality, and very affordable as the prices are directly from the manufacturer. Small pellet mills are generally all flat die pellet mills. The flat die pellet mill is a upright design. The rollers sit on greatest of the die, applying pressure vertically to the greatest surface of the die. Depending on the design, either the roller shell or die will be stationary plus the other will rotate. Material enters from the top, and falls between the rollers plus die. The pellets come because of the bottom of the die, along with are cut to length via a knife. Pellet length is much more important than many people appreciate. Some pellet stove augers cannot handle oversized pellets, causing damage to the auger or simply blocking in addition to causing the stove to confront operating properly. One view that many people in the pellet construction market including PelHeat share is that pellet construction is more of an art than an specific science. The reasons for this are each raw matter has its own unique characteristics. Component of the differences lie in the percentage of unrefined lignin found within the raw material. Lignin is the organic binding agent found in all wood materials, under the temperature along with pressure of the pellet mill the lignin is melted. Once the pellet has been formed the lignin cools to produce pellets.

Before the raw material is suitable for the pellet mill, it first must be prepared correctly. For case if you wish to manufacture 6mm pellets, which is the size of pellet most pellet stoves use, you must provide the pellet mill by way of a raw material of 6mm or below. Therefore this method sawdust is appropriate, yet biomass chips are going to call for more processing. After wood has been chipped, the finest piece of apparatus to reduce the chips further in size is a hammer mill. A hammer mill factory on the principle of attrition. Through the speed impact of the hammers on the wood chips, the chips are shattered into smaller particles. To make sure the particles are below 6mm a screen is placed in the hammer mill. Therefore no particles can escape the hammers until they are below 6mm in size. Once the material is off a suitable size, generally is must be dried before entering the pellet mill, this is particularly true is the wood chips are from fresh virgin wood. For small scale pellet production, the most practical and affordable technique of drying the matter is owing to a flash dryer. Flash dryers are also known as vent dryers or air current dryers. The hot air is generated in the stove burning wood logs, chips or pellets. From the stove there is then a series of pipes by expansion chambers. A fan pulls the wet matter because of the vent, in doing so exposing the wet particles to the hot air from the stove. At the end of the smokestack system a cyclone separates the dry material.
