With decades of experience, Leesh Holdings has emerged as one of the top suppliers of steel castings, specializing in wear-resistant products—especially High Chrome White Iron castings.

High Chrome White Iron is highly sought-after for its exceptional wear resistance, making it the ideal choice for manufacturing Grinding Roll Sleeve. This critical component is widely applied in power plant coal pulverizer mills and cement factory cement grinding mills, where durability under heavy wear is essential.

A key application of High Chrome White Iron is in grinding roller tyres (also known as Cr2021 in China) for power plant pulverizer mills, and our Grinding Roll Sleeve stands out as a high-quality OEM product. As a professional China-based supplier and manufacturer, we offer Grinding Roll Sleeve at competitive prices, with wholesale options available for customized orders to meet diverse client needs.

To ensure the superior quality of our Grinding Roll Sleeve and grinding roller tyres, two core factors are strictly controlled. First, the material must fully comply with required standards—we use a SPECTRO Direct Reading Spectrometer and standard Cr2021 material reference blocks to monitor material content for every casting, guaranteeing consistency. Second, heat treatment is executed to the highest standards; leveraging decades of expertise in High Chrome White Iron, our team masters the precise heat treatment process for Grinding Roll Sleeve, enhancing its wear resistance and service life.

Today, Leesh Holdings supplies top-tier Grinding Roll Sleeve and grinding roller tyres to global markets, including Japan, Malaysia, and beyond, earning trust for reliable performance and quality.
