As a common environmental protection equipment, one of the core components of biomass briquetting machine is the mold. The state of mold directly affects the working efficiency of equipment and the quality of finished products, so it is particularly important to judge and replace the mold in time. So, how to judge whether the mold of biomass briquetting machine needs to be replaced? The following are several key judgments.

1. The quality of finished products declines.

When the mold is seriously worn, the pressed biomass particles or block products may have problems such as irregular shape, insufficient density or rough surface. If it is found that the quality of the finished product is obviously decreased, it is necessary to check whether the mold is worn or blocked.

2. The output is significantly reduced.

The wear of the mold will lead to the decrease of the efficiency of the equipment in the pressing process, thus affecting the overall output. If the output drops sharply under the normal operation of the equipment, it may be a signal that the mold needs to be replaced.

3. The surface of the mold is worn or cracked.

Regular inspection of the surface of the mold is an important method to judge its state. If obvious wear marks, cracks or aperture deformation are found on the surface of the mold, it means that the mold can no longer meet the normal use requirements and needs to be replaced in time.

4. Increased pressure or abnormal noise.

When the mold is worn, the pressure and resistance may increase when the equipment is running, accompanied by abnormal noise. In this case, stop the machine immediately to check whether the mold needs to be replaced, so as to avoid damage to other parts of the equipment.

5. Expiration of service life

Each mold has its designed service life. According to the recommendation of the manufacturer and the actual use, changing the mold regularly can avoid the influence of excessive wear on the equipment operation. Even if there is no obvious problem, it is recommended to replace it after its service life expires.

The mold of biomass briquetting machine is an important part of equipment operation. Timely judgment and replacement of mold can not only ensure the normal operation of equipment, but also improve production efficiency and finished product quality. Therefore, users should pay more attention to the state of the mold in daily use, and take timely maintenance or replacement measures in combination with the quality and output changes of finished products and the mold itself to prolong the service life of the equipment.
