Product Description

Good ring die wood pellet mill has a ring shaped die and a set of rollers. The die it positioned vertically with the rollers set within the die applying force to the inner edge of the ring. Due to the vertical roller and die position a motor is required to meter raw material into the centre of the ring, this also provides more control. Most ring die pellet mills operate with a driven ring and a stationary roller set. However there is a small selection of ring die pellet mills with a stationary die and rotating roller set. Some ring die pellet mills are direct gear driven from the motor, while others are belt driven. The advantages of gear driven is a more positive driving force without the possible slipping of belt systems. However belt driven mills are more economically and access for drive changes are easier and cheaper. The speed of the mill is dictated by the raw material being processed, for example one speed maybe suitable for grass but not for wood. There is more on the importance of different die speeds in the guide. Website: http://www.woodpelletmillchina.com/news/n10.html
