Description

Technical Field

[0001] The utility model relates to the field of particle forming machines, in particular to a biomass fuel particle forming machine. Background Art

[0002] A small biomass fuel pellet machine is a device that processes biomass raw materials (such as sawdust, straw, rice husk, etc.) into pelletized fuel.

[0003] In the existing small-scale biomass fuel pellet machine, the adjustment structure of the four pressure wheels is set separately, and when adjusting the pressure of the pressure wheels, it is impossible to achieve synchronous adjustment of the four pressure wheels.

This method makes it difficult to ensure that the distance between the four pressure wheels and the forming disk is completely consistent, resulting in differences in the quality of the produced pellet fuel. The uneven distribution of pressure will cause some pressure wheels to bear excessive pressure. Working under such uneven pressure for a long time will accelerate the wear of components.
