Friends, when choosing the material of the plastic crusher blade, you must consider the following key factors:
1. Type of broken plastic
If the broken is a common hardness of plastic, such as polyethylene (PE), polypropylene (PP), etc., tool steel or alloy steel blades may be sufficient.
For engineering plastics with higher hardness, such as polycarbonate (PC), nylon (PA), etc., it may be necessary to choose carbide or high-chromium cast iron blades to ensure adequate wear resistance and cutting ability.
2. Crushing amount and working intensity
High-yield, long-term continuous operation of the crusher, the need for more wear-resistant, higher strength materials, such as carbide.
In the case of small crushing amount and low working intensity, tool steel or alloy steel materials can usually meet the needs and the cost is relatively low.
3: Budget
The blade cost of high-performance materials such as carbide is higher, if the budget is limited, you can first consider alloy steel or tool steel materials.
However, be aware that although the initial investment is low, it may increase the long-term cost due to frequent blade replacement.
4. Wear resistance requirements
Where the wear resistance is very high, the preferred choice is cemented carbide or high chromium cast iron.
If the wear resistance requirements are general, tool steel and alloy steel are also available as options.
5. Impact resistance needs
If a large impact may be encountered during the crushing process, such as the crushing of plastics containing impurities or plastic parts of larger size, materials with good impact resistance should be selected, such as alloy steel.
For example, a small plastic recycling plant that mainly breaks common polyethylene and polypropylene plastic bottles, has a small output and a limited budget, then the choice of alloy steel blades may be more appropriate.
And a large plastic processing plant, the need for long-term, a large number of broken various engineering plastics, and the crushing efficiency and quality requirements are very high, then carbide blade is a better choice, although the initial investment is high, but in the long run can reduce the cost of maintenance and replacement of the blade, and ensure the stability and efficiency of production.
