The compression ratio of the biomass pellet machine mold refers to the ratio of the effective length of the ring mold hole to the minimum diameter of the ring mold hole. It is an indicator reflecting the extrusion strength of wood chips. The greater the compression ratio, the more solid the extruded wood chips. For the ring mold with straight holes, the effective length of the ring mold hole is the total thickness of the ring mold, and the minimum diameter is the diameter of the mold hole itself.

For the release-type stepped holes and external conical holes, the effective length of the mold hole is the total thickness of the ring mold minus the length of the release hole or the length of the external conical hole. The diameter of the small diameter section is the diameter used for calculating the compression ratio.

The compression ratio of the biomass pellet machine mold refers to the ratio of the effective length of the ring mold hole to the minimum diameter of the ring mold hole. It is an indicator reflecting the extrusion strength of wood chips. The greater the compression ratio, the more solid the extruded wood chips.

For compression-type stepped holes and internal conical holes, this situation is rather special. Generally, the entire thickness of the ring mold is taken as the effective length of the mold hole, and the minimum diameter is the diameter of the small diameter section. Of course, the meaning of the ring mold compression ratio calculated in this way is different from the previous two cases.

The current of the biomass pellet machine is controlled according to the specified load. It is absolutely not allowed to operate beyond the load for a long time. This is the main cause of equipment damage. During the entire process, the biomass pellet machine should operate close to full load to achieve its best production state.

During the operation of the biomass pellet machine, the feeding speed should not be too fast. After about 10 minutes, the body begins to heat up. Then, the normal feeding speed can be used. Otherwise, it will cause blockage and high temperature. Before starting, it is necessary to check whether the oil pump of the biomass pellet machine is normal and whether the oil circuit is unobstructed to prevent the bearings and other components from being burned by high temperature.
