How to adjust the biomass pellet mill pressure roller gap

The adjustment of biomass pellet mill pressure roller gap is a key step to ensure the normal operation of the equipment and stable quality of pellets.The adjustment of biomass pellet mill pressure roller gap is a key step to ensure the normal operation of the equipment and the stability of pellet quality. The following is a detailed description of the biomass pellet mill pressure roller gap adjustment method, divided into manual adjustment and automatic adjustment of two ways, and combined with the actual operation of the precautions to be explained.

1.Manual adjustment method

Steps are as follows:

(1)safety preparation: the first off the power supply, in order to prevent accidental startup.

(2)loosen the fixed screws: remove the pressure roller guard, use tools (such as wrenches or open-ended pliers) to loosen the fixed screws on both sides of the pressure roller. Pay attention to keep the same degree of loosening of both sides of the screws, so as not to cause the pressure roller offset in the adjustment process.

(3)adjust the gap: according to the production demand and quality requirements of particles, use a wrench or adjusting tool to gently adjust the position of the pressure roller, so that the gap between it and the ring die to reach a predetermined value. Usually, this gap needs to be determined according to the nature of the material, moisture content and the diameter of the particles and other factors. During the adjustment process, it should be ensured that the gap between the two sides of the pressure roller remains consistent to avoid causing differences in the quality of the particles.

(4)tighten the screws: after the adjustment is completed, re-tighten the fixed screws on both sides of the pressure roller to ensure that the pressure roller position is stable. Then, install the protective cover to prevent accidents during the operation of the equipment.

(5)Trial run check: Start the machine for trial run to observe the molding of particles, output and the operating status of the equipment. If necessary, fine-tune the pressure roller gap according to the results of the trial run.

2.Precautions

(1)Safety first: when adjusting the pressure roller gap, must ensure that the equipment is in a state of shutdown, and disconnect all electrical connections. At the same time, the operator should wear protective equipment to prevent accidents.

(2)Accurate Measurement: During the adjustment process, precise measuring tools should be used to measure the gap between the pressure roller and the ring mold to ensure its accuracy.

(3)Regular maintenance: regular maintenance of the equipment, including checking the wear and tear of the pressure roller and ring die, replacing the lubricant, etc., in order to ensure the normal operation of the equipment and the stability of the quality of particles.

(4)Adaptation adjustment: according to the changes in production demand and the nature of the material, adjust the pressure roller gap and pressure value in time, in order to adapt to different production conditions.

In summary, the adjustment of biomass pellet mill pressure roller gap is a complex and detailed process, requiring operators to have rich experience and professional knowledge. Regular maintenance can ensure the normal operation of the equipment and the stability of the pellet quality.
