The Advantages Of The Horizontal Ring Die Pellet Mill

There is now a general consensus among the pellet production community that ring die pellet mills are a more suitable design than flat die pellet mills. Ring die pellet mills consume less power and produce better quality pellets with less parts wear. All the pellet plants we promote use ring die pellet mills, however our small scale pellet plants use a special type of pellet press. In most ring die pellet mills the die is vertically mounted. What this means is that material has to be forced into the centre of the die through augers etc. As the rollers are mounted half way up the ring die, this means that the rotation of the die is what carries material up between the roller and die for compression.

Supporters of flat die pellet mills suggest that this can lead ring die pellet mills to struggle to compress light lower density materials that will sit in the base of the press and not be carried up. There is some evidence to support this, with some pellet plants struggling to process some straw materials. However the pellet mills used in our small pellet plants are horizontally mounted. The die and rollers sit at the base of the mill and the material falls via gravity into the compression zone. What this means is that these pellet presses are taking the last advantages of the flat die pellet mill and implementing it into the design of ring die pellet mill. These means that these pellet plants can be used to process virtually any organic material whether its for creating fuel pellets or feed pellets, the press can deal with the material successfully and efficiently.
