Made of high-chromium wear-resistant cast iron.
Qingdao KEEJOO Group's shot blasting machine blades and wear-resistant parts are made of high-chromium investment cast Cr27. This material with a hardness of up to 1300–1800 HV (approximately HRC 60 or higher), far exceeding that of ordinary cast iron, and effectively resisting repeated impact and cutting wear from steel shot or steel grit.
Precision manufacturing processes guarantee performance
The blades are manufactured using a high-precision CNC machining center in a single process, ensuring geometric accuracy and uniformity of the internal structure. The hardness of the blades is evenly distributed from the center to the outer surface, preventing premature fracture due to stress concentration.
Proven to have a long service life
Under actual working conditions, the service life of shot blasting machine blades made of high-chromium cast iron is generally between 800 and 4000 hours. Considering that tens of thousands of steel shots are projected per hour, this means that a single blade can withstand tens of millions or even hundreds of millions of high-speed impacts.
Highly reliable design
As a national high-tech enterprise and industry technology center, Qingao KEEJOO Group shot blasting machines are designed with a strong emphasis on reliability. For example, it uses German Schenck or similar high-precision dynamic balancing instruments to ensure the balance of the impeller during high-speed operation, reducing vibration; and it selects international brand bearings such as SKF to guarantee stable transmission. These measures indirectly protect the blades, allowing them to achieve maximum wear resistance under ideal operating conditions.
In summary, Qingdao KEEJOO Group shot blasting machine blades, through the use of top-grade wear-resistant materials, precision manufacturing, and systematic design, achieve durability far exceeding industry standards, enabling them to perform exceptionally well in high-intensity, continuous industrial operations.
