How to Make Granulator Blades Sharper?

If you work in the recycling field, you must be familiar with the copper granulator machine. Then, you will inevitably encounter an unavoidable problem:  the blade of the copper granulator machine becomes blunt. Today, let’s discuss this problem.

Brief Introduction to Granulator and Its Blades

As a professional scrap cables processing equipment, the copper wire granulator machine plays a vital role in the recycling field. Its main function is to crush and separate scrap cables to extract pure copper granules.

How does the copper wire granulator machine extract pure copper granules? This has to talk about the working principle of the copper wire granulator machine, and among them, its blade plays an indispensable role. The blade is the core part of the copper wire granulator machine, and its sharpness directly affects the working efficiency and product quality of the equipment.

Know About Blades of Granulator

We mentioned the importance of blades above, now let’s take a look at the materials and functions of blades.

🔺 Materials of Blades

There are three main materials for blades of granulator in the market: 55SiCr, 9crsi, Cr12MoV (SKD-11, DII).

Using 55SiCr to make granuator blades is cheaper and has better toughness. It is not easy to chip when processing raw materials containing iron impurities. However, the wear resistance is not very good. In actual use, it requires very frequent sharpening, and the blade wear is also very large.

9crsi is a commonly used low alloy tool steel with high hardenability, as well as high tempering resistance. It can be used to manufacture tools with complex shapes, small deformation, high wear resistance and low-speed cutting. It is the material of the blade of the granulator that is currently widely used.

Cr12MoV has high hardenability, wear resistance and strength. Compared with 9crsi, the wear resistance can be increased by 2-3 times, making it an ideal material for granulator blades.

In view of the above, our company’s D series copper wire granulator machine uses Cr12MoV as the material to make blades to ensure the high performance, durability and longevity; for our N series high end granulator, standard blades material is 9crsi, of course you can choose SKD-11 also.

🔺 Functions of Blades

The main function of the copper wire granulator machine blades is to crush scrap cables and plastic.‌

The copper wire granulator machine blades is designed mainly for crushing scrap wires. These blades can cut and crush wires, breaking them into smaller granular substances. ‌Specifically, our copper wire granulator machine blade processes the scrap wires into granules through strong rotary cutting and crushing. These particles will be conveyed the sorting system, through the air vibration system and the blowing of the fan, copper and other valuable materials flow to different holes. ‌Such a handling process not only realizes the effective recycling of scrap wires, but also improves the utilization rate of resources and reduces waste.

Factors that Affect the Sharpness of Blades

So, what factors affect the sharpness of the copper wire granulator machine blades? Here are a few reasons summarized:

🔹 Manufacturing Quality of Blades

The production process of the blade is very complicated and requires a series of fine processing to obtain high-quality copper wire granulator machine blades. 

• Find high-quality alloy raw materials. 
• The alloy raw materials need to be processed in the furnace and undergo chemical reactions to achieve the initial separation of impurities from the alloy materials.
• The alloy materials need to be heat treated and the alloy materials are forged multiple times until the impurities in the material are completely removed.
• The alloy material undergoes precision machining, which includes CNC machining, grinding, polishing, etc..

During the blade-making process, the temperature of heat treatment, and the level and experience of the manufacturing workers will all affect the quality of the final blade. After so many years of experience comparing many suppliers, our company chose one or 2 suitable raw material suppliers and maintained a stable cooperation, ensuring the quality of the blade raw materials. In addition, we have more than 25 years for the production of blades, and we have experienced workers and mature manufacturing technology to ensure that the blades we make are of high quality, strong wear resistance and longer service life.

🔹 Using Frequency

The second influencing factor is the frequency of use of the blade. During the use of the copper wire granulator machine blade, as the frequency of use increases, the blade will gradually wear, resulting in a decrease in sharpness. This is because during use, the blade will rub against the processed material, resulting in a gradual loss of material on the blade surface, thus affecting its cutting efficiency and accuracy. Therefore, the sharpness of the blade will decrease as the frequency of use increases.

🔹 Operating environment of blades

Copper wire granulator machines are mainly used to process scrap electric wires. The components of these wires are complex, including wires of different thicknesses and different degrees of hardness. If you have been using the blade to process wires with a lot of plugs or irons, after high-speed rotary cutting, the blades are severely worn.

How to Make Granulator Blades Sharper?

After the blade of the copper wire granulator machine becomes dull, how should we improve its sharpness? Here are some solutions to keep your blades sharper:

⭐ Choosing Suitable Blades Sharpening Tool

After the blade becomes dull, you must not sharpen it at will. You can use a sharpener to sharpen it, but you must choose a suitable sharpener. When choosing a sharpener to sharpen the granulator blades, you should pay attention to the following points to ensure the sharpening effect and safety:

Our company has a special sharpener. If the blades of the copper wire granulator machine need to be sharpened, you can contact Jocy: 📞0086 13772508206

⭐ Install Blades Correctly

The blades of granulator need to be installed correctly, otherwise the service life of the blades will be affected.

Before our machines are shipped, there will have detailed instructions for use. If you have any questions about the instructions, you can also contact our after-sales staff at any time, who will provide you with professional technical answers to ensure that you can correctly install the blades of the copper wire granulator machine, allowing you to use it without worries.

⭐ Sharpen Blades Regularly

The blade of the copper wire granulator machine is a consumable part, so the wear of the blade is inevitable, but we can sharpen it regularly to ensure the sharpness of the blade. We suggest that you can check your machine every two weeks, and sharpen the blades once a month. If you feel that the crushing speed is slow or the crushing effect is not as good as before, you can also sharpen the blade. However, it is worth noting that the blades will become narrower after repeated grinding. When the gap between the movable blade and the fixed blade cannot meet the crushing requirements, the old blades need to be replaced. And the gap between the movable blade and the fixed blade should be adjusted after each grinding or blade replacement.

⭐ Maintenance of Blades

During the use of the copper wire granulator machine, we should pay attention to the maintenance of the machine blades.

Conclusion

IN BRIEF, maintaining granulator blades ensures the most efficient performance of your granulator, resulting in greater throughput and higher-quality output, and helps to reduce the cost of maintaining a Granulating machine.
