Discussion on Two Key Parts of Wood Pellet Mill

As an amazing machine to turn agricultural wastes into biomass pellets of great value, wood pellet mill is a project that is worthy of investment. Press roller and ring die are two key parts in wood pellet machine and their performance can directly decide the working efficiency.

Theoretically, surface hardness of press rollers should be smaller than that of ring die. In this way, service life of ring die can be ensured. in principal, new ring die is equipped with new press roller. The best ratio in service life between press roller and ring die is 1:1. At abroad, the ratio is 1:3.

It is quite important to adjust the distance between press roller and ring die. If distance is too small, wear will be serious. On the contrary, press roller is easy to slip off and pellet quality is poor. Distance between press roller and ring die generally changes from 0.1 to 0.4. In general, material distance in ring die wood pellet mill is from 0.1 to 0.3. It is from 0.005 to 0.3 in flat die wood pellet mill.

After installing the press roller into ring die, you can adjust the distance between outer surface of press roller and inner surface of ring die by adjusting the eccentric shaft. The press roller should be adjusted to the degree that slightly touches the ring die. Interested in the price of wood pellet mill? Click website to download.
