Plastic granulators are a common piece of equipment used in numerous recycling industries. When selecting a satisfactory plastic granulator machine, there are several key aspects to pay close attention to. A good plastic granulator is not only about the quality of the machine itself, but also the importance of after-sales maintenance services. What should we be aware of when purchasing a plastic granulator? Let's find out below.
1. The actual operability and maintainability of the equipment. Plastic granulator production requires regular maintenance, so when purchasing a used plastic granulator, it's crucial to understand whether the manufacturer's after-sales maintenance and repair services are comprehensive and well-established.
2. Ensuring Overall Quality of Extruded Products: Generally, the quality of extruded products is assessed based on both their internal and external quality. Internal quality encompasses the physical and chemical properties as well as uniformity of the extruded material. External quality includes the geometric shape, specification dimensions, appearance, and color of the extruded product.
3. The Practicality and Efficiency of Plastic Granulating Machines: For a wide range of product processing (such as different polymers, various products, etc.), it is advisable to choose a highly practical extruder. For products with a single processing focus, a plastic granulating machine is more suitable. This may result in excellent equipment performance, compact structure, high overall level of automation technology, and cost-effective pricing.
4. Equipment lifespan: The natural lifespan of extruders is relatively long, primarily due to the condition of the barrel wear and the reducer wear. With a well-designed, material-selected, and high-quality extrusion system and reduction system, the increased equipment investment is offset by the extended lifespan, making it economically and scientifically reasonable.
5. Energy Consumption: Generally, it is measured by the power value consumed per unit of production or sales within a certain time frame. The main energy losses of a plastic granulator in terms of single-time, single-output functionality are primarily composed of driving and heating components. A comprehensive and itemized understanding should be conducted.
Equipment Production Efficiency: Includes the production output of plastic granulators, extrusion speed, and the overall level of automation technology. Generally speaking, the larger the screw specification, the higher the production output. However, the cost of purchasing and operating the machinery is also higher, and it occupies more space. The higher the extrusion speed, the greater the production efficiency; but the energy consumption increases, and the cost of component repairs rises. The overall level of automation technology in the extrusion machine's temperature, pressure, and drive control systems is high, which is beneficial for improving production efficiency. However, the price of the machinery and equipment is high, and the overall level of maintenance requirements is high.
