Granulator vacuum equipment, dry screw vacuum pump
In the selection process of granulation machine vacuum pump equipment, dry vacuum equipment has become the first choice for many enterprises due to its high efficiency, stability, and environmental protection characteristics. Dry vacuum equipment adopts advanced vacuum technology, which can ensure efficient pumping while achieving an oil-free, waterless, and pollution-free vacuum environment. This equipment not only improves production efficiency and reduces energy consumption, but also saves a lot of maintenance costs for enterprises.

What to do with hollow granulation burrs, using a dry vacuum pump system
In industrial production, the burrs and hollow problems generated during the granulation process have always plagued many manufacturers. These problems not only affect the appearance quality of products, but may also have adverse effects on their performance and service life. To address these issues, the introduction of dry screw vacuum pumps and dry claw vacuum pumps as solutions has gradually gained recognition and application in the industry.
Firstly, let’s explore the reasons for burrs and hollows generated during the granulation process. Burrs are mainly caused by uneven compression and shear forces on the material during granulation, resulting in irregular protrusions on the surface of the material. Hollow is caused by the failure of internal gas to be discharged in a timely manner during granulation, leading to the formation of voids inside the particles. To solve these problems, we need to start from improving granulation processes and introducing efficient vacuum equipment.
Dry screw vacuum pump, as an oil-free and waterless vacuum equipment, has many advantages. Firstly, dry vacuum pump does not require lubricating oil and cooling water, avoiding product quality problems caused by oil-water pollution. Secondly, dry vacuum pump has high pumping rate and low ultimate vacuum degree, which can quickly and effectively discharge the gas generated during the granulation process. Finally, dry vacuum pump also has low maintenance cost and long service life, which can reduce the operating cost of enterprises.
During the granulation process, we can apply dry screw vacuum pumps to the following stages:
1. Raw material pretreatment: Before granulation, the raw materials are pretreated, such as drying, screening, etc., to reduce the moisture and impurities in the raw materials. At this time, a dry vacuum pump can be used to vacuum dry the raw materials to remove moisture and volatile substances, and improve the quality of the raw materials.
2. Vacuum exhaust of granulator: In the granulator, materials are compressed and sheared to form particles. At this time, a dry vacuum pump can be used to vacuum exhaust the granulator to remove gases and volatiles from the materials, reducing the generation of burrs and hollows.
3. Particle screening and packaging: During the particle screening and packaging process, a dry vacuum pump is used to vacuum exhaust the screening machine and packaging machine to remove residual gases and impurities from the particles, thereby improving the appearance quality and performance of the product.
In addition to the dry screw vacuum pump, the dry claw vacuum pump is also a vacuum equipment suitable for the granulation process. The dry claw vacuum pump has the advantages of compact structure, high pumping efficiency, wear resistance, etc., and is suitable for vacuum exhaust of high-temperature and high viscosity materials. During the granulation process, the dry claw vacuum pump can effectively discharge gases and volatiles in the material, reducing the generation of burrs and hollows.
However, simply introducing dry screw vacuum pumps or dry claw vacuum pumps cannot completely solve the problems of burrs and hollows in the granulation process. We also need to start from the following aspects:
1. Optimize granulation process: By adjusting the parameters and process flow of the granulator, the material is subjected to more uniform extrusion and shear forces during the granulation process, thereby reducing the generation of burrs and hollows.
2. Improve raw material quality: Select high-quality raw materials, strictly screen and dry them, reduce impurities and moisture content in the raw materials, and improve the quality of the raw materials.
3. Strengthen equipment maintenance: Regularly maintain and upkeep the granulator and vacuum equipment to ensure their normal operation and efficient work.
In summary, the introduction of dry screw vacuum pumps and dry claw vacuum pumps as one of the means to solve the problems of burrs and hollows in the granulation process has been widely recognized and applied in the industry. However, to truly solve these problems, it is necessary to start from optimizing the granulation process, improving the quality of raw materials, and strengthening equipment maintenance, and take comprehensive measures to achieve better results.
