As one of the critical equipments in modern plastic processing, the operation efficiency of mesin peleburan pelet plastik is directly related to the production output and quality. Among them, feeding speed is an essential parameter in the operation process of the plastic pellet melting machine, which is affected by various factors. In this article, we will introduce the factors affecting the feeding speed of plastic granulators and the methods to improve the feeding speed to increase the output.
Factors affecting plastic pellet melting machine’s feeding speed
Characteristics of raw materials
The characteristics of raw material is one of the important factors affecting the feeding speed of plastic granulator. Different types of plastics have different melting characteristics and flowability. For example, high molecular-weight plastics require more energy to heat and melt, which may result in a slower feed rate. Therefore, the type of plastic raw material, particle size and melt properties all have an impact on the feed rate.
Mechanical structure and design
The mechanical structure and design of the plastic pellet melting machine will also affect the feeding speed. Reasonable screw design, heating area settings and heating power matching can more effectively improve the melting speed of plastic, thus affecting the overall feeding speed.
Temperature control
Temperature is critical to the melting and fluidity of plastics. Appropriate heating temperatures promote the melting of plastics, making it easier for them to enter the screw for pelletizing.
However, too high a temperature may lead to decomposition and degradation of the plastic, affecting the quality of pelletizing. Therefore, precise temperature control is the key to improving the feed rate.
Screw speed
Screw speed is an important parameter for regulating the feeding speed of plastic pellet melting machine. Appropriate screw speed can improve the feeding speed under the premise of ensuring the full melting of plastic. However, too high a screw speed may cause the plastic to stay in the screw channel for too short a time, affecting the melt quality.
Pressure control
Plastic is subjected to a certain pressure in the screw channel, and the amount of pressure is directly related to the flowability of the plastic. Appropriate pressure can promote the smooth flow of plastic in the screw channel and improve the feeding speed of plastic pellet melting machine. However, too much pressure may lead to screw clogging or other problems.
Methods to increase the feeding speed
- Optimize raw material selection: Select raw materials suitable for the performance of the mesin peleburan pelet plastik to reduce the melting energy consumption of plastics and increase the feeding speed.
- Improvement of mechanical design: Continuously optimize the screw structure, heating zone distribution and heating power matching to improve the melting efficiency and overall feeding speed.
- Precise temperature control: Use advanced temperature control system to ensure that the plastic is melted within the appropriate temperature range and increase the feeding speed.
- Adjustment of screw speed and pressure: Under the premise of guaranteeing the melt quality, adjust the screw speed and pressure at the right time to improve the feeding speed.
