1: Uneven particle size distribution
Uneven particle size distribution refers to the presence of particles of different sizes in the produced pellets. This may be caused by uneven mixing of raw materials or improper adjustment of the pelletizing equipment. To solve this problem, first ensure that the raw materials are fully and evenly mixed. In addition, it is necessary to adjust and optimize the parameters of the pelletizing equipment, such as adjusting the speed, angle and spacing of the cutting tool to ensure the consistency of the size of the pellets.
2: Too high or too low water content
The water content of pellets has an important influence on their storage stability, fluidity and subsequent processing performance. Too high water content may cause adhesion and agglomeration between particles, increasing the difficulty of storage; while too low water content may make the particles fragile and increase dust, affecting the working environment and product quality. Therefore, it is crucial to strictly control the moisture content during the production process. At the same time, strengthen the humidity control of the warehouse environment to prevent the pellets from absorbing moisture or losing water during storage.
| Model | Capacity(t/h) | Power(kw) | Screw Diameter(mm) | Weight |
| 75-B | 0.3-0.4 | 22 | 80 | 1000 |
| 85-B | 0.5-0.6 | 30 | 90 | 2000 |
| 90-B | 0.6-0.7 | 37 | 100 | 2100 |
| 100-B | 0.7-0.8 | 55 | 120 | 2200 |
| 135-B | 1-1.5 | 75 | 135 | 3200 |
| 145-B | 2-3 | 90 | 145 | 4000 |
3: Appearance defects of pellets
Appearance defects include cracks, pores and irregular shapes on the surface of the particles. These are usually caused by improper temperature control during drying and cooling. To improve this situation, it is necessary to accurately control the temperature curve of the drying and cooling process to avoid excessive temperature fluctuations. In addition, it is also very important to regularly inspect and maintain the equipment to ensure that it is in optimal working condition.
Four: High dust content in granular materials
High dust content in granular materials not only affects the working environment, but may also pose a threat to human health. This problem is usually related to the pretreatment and cleanliness of the raw materials. In order to reduce the dust content, the raw materials need to be fully cleaned and screened before entering the production line to remove impurities and dust. At the same time, the operating efficiency of dust removal facilities in the production process should be strengthened to ensure the normal operation of the air purification system.
