Granulator Cutter Mainly used for the most common waste plastic granulation, such as processing waste plastic products, plastic basins, handbags, plastic barrels, agricultural convenience bags, beverage bottles, furniture, daily necessities, etc. During daily use, Many factors affect the service life of the granulator cutter. Let's take a look below.

　　1. Influence of titanium dioxide content on slice quality

　　Titanium dioxide is a matting agent in polyester production and an indispensable additive in chemical fiber production, but titanium dioxide has an important influence. When the titanium dioxide content increases, the service life of the granulator cutter decreases sharply; When the titanium dioxide content is close to zero, the service life of the cutter can be very long. Titanium dioxide has a great influence on the service life of the cutter. Under the premise of not affecting the quality of polyester products, the amount of titanium white powder should be kept reasonable when injecting titanium white powder.

　　2. Influence of tool processing

　　After normal grinding of the cutter by the granulator cutter, there are many small peaks on the cutting edge. These peaks are very sharp, but very fragile and easy to break. The fracture of the rear small peak leads to increased cutting force, generates more heat, and shortens the service life of the cutter. Therefore, the small spikes must be carefully processed before use to reduce local stress concentration and thus improve impact resistance and extend the service life of the cutter.

　　3. Influence of cutting gap

　　The so-called cutting gap is the gap between the moving knife and the fixed knife. Within a certain range, the larger the cutting gap, the smaller the cutting force required; conversely, the larger the cutting force, the greater the wear and tear of the granulator cutter; When the gap is close to zero, the cutting force will become quite large, and the strength of the blade cannot withstand it, and it will break; However, if the gap is too large, the quality of the slices will be significantly affected. Therefore, the cutting gap must be reasonably selected in production. According to experience, the cutting gap is controlled between 0.03 and 0.04 mm, which can ensure a certain cutting force and obtain qualified slices.

　　4. Influence of softened water

　　Softened water is indispensable in the granulation process. It not only cools the casting belt of the conveying material, but also has a certain influence on the use of tools. Softened water can promptly remove the heat generated during cutting, reduce the wear rate of the cutter, and also play a certain lubricating role. Without demineralization, the heat loss will be slower, and the cutter wear will accelerate. However, excessive softened water will hinder the operation of the cutter and slicing, resulting in increased noise and cutting consumption. At the same time, softened water will also enter the mechanical transmission part. The purity of softened water also has a great influence on the tools. Solid impurities in softened water will quickly wear the cutter. Therefore, the role of softened water in the cutting process has both advantages and disadvantages, and it should be strictly controlled in actual production.
