How to Improving Rotor Tips Using life of VSI Sand Making Machine
Rotor Tip is a key spare part for VSI sand making machine, and wear resistance is a key factor effects the rotor tip using life, and how to improving the rotor tip performance is a key factor of good sales of the vsi sand making machine. From above information, we can get a conclusion: How to find a good way to improve the rotor tip wear resistance is very important.
Rotor tip of the sand making machine main function is breaking the 30-45mm small stones to sand. With this usage, it needs good wear resistance and impact. Tungsten carbide is the best choice for it.
Below product is main rotor tip at current market. Some are high frequency welding, and some are glued. Because of the bonding strength is not high, the using performance is not satisfied.
Below is the picture of rejected items:
How to solve this problem? If we use the whole part as carbide, the cost is very high, not economical. How to combine? Vacuum brazing is the solution.
Vacuum brazing has very high bonding strength, which easily solve the carbide falling off during using problem. According the onsite usage, developing a proper grade for the rotor tip to improving the performance of the sand making machine is another thing our company done. With the correct grade, we balanced the abrasion and impact well. The third thing we do is to make a new design. Brazing carbide on all the abrasion area.
What is final design of our company products, I keep it as a secret at this moment. If you are interested in it, or you have a good idea and solution on it, welcome to send me email. We can discuss it :)
