| Tip 1 | About the Compression Ratio of the ring die mould. |
| define "L" as the effective hole length of the ring die. define "D" as the effective hole diameter of the ring die. the Compression Ratio = L / D. | |
| The higher Compression Ratio, the more compact that the biomass sawdust wood pellet will be, and the pelleting speed will be reduced accordingly. | |
| Tip 2 | Ring die failure cause analysis |
| After a period of working, the hole inside wall friction losses increased, A) the diameter of the hole increased, and the diameter of final product biomass wood sawdust pellet exceed the specified value. | |
| B) the scraggly of the hole inside wall get worse, the wood sawdust raw material will easy to block, the capacity will decrease. | |
| C) the thickness of the hole wall will be reduced, the structural strength of the ring die mould will be highly reduced. | |
| Tip 3 | number of reasons cause the ring die friction losses. |
| A) the fineness of the biomass wood sawdust powder raw material. the more fine the raw material is, the more easier to make pellet. otherwise, too coarse granular size of the raw material will increase the friction losses of the ring die. Generally, all of the raw material partical size should be more than 8 mesh, the proportion of partical that above 25 mesh should not less than 65%. for those high coarse fiber raw material, we should add some oil to reduce the friction, and the surface of the final pellet will look more smooth. | |
| B) the impurity in the raw material will accelerate the friction losses. hence the raw material cleaning is very important. | |
| C) the space between the press roller and the ring die mould. It will speed up the friction if the space is too small. the ideal space is 0.2-0.4 mm. the space selection will depend on the diameter of the pellet. smaller diameter, smaller space. when we replace the ring die mould with a new one, the space should be set as lower value. |
