Our flagship product — cast high-chrome iron grinding balls with superior hardness, low wear rate, and consistent chemical composition for demanding milling applications across five proven grades.
BCL KROME grinding media balls are manufactured from cast high-chrome iron using a precisely controlled production process. Every ball delivers consistent hardness from surface to core, optimum chromium carbide distribution, and retained austenite below 5% — eliminating microchipping and ensuring maximum service life in your mill.
All sizes are manufactured as per customer requirement. Our five-grade range covers every application from cement raw mills and coal mills to highly corrosive wet mineral grinding environments.
Five grades covering the full spectrum of cement, mineral, and industrial grinding applications.
| Type & Designation | Chrome % | Hardness (BHN) | Application |
|---|---|---|---|
| BCL KROME – 12 | 10–14% | 580–700 | Cement Industries for Raw Mills, Cement Mills & Coal Mills, Mineral Grinding, Thermal Power Plants for Coal Pulverizing, Fertilizer Plants |
| BCL KROME – 17 | 16–18% | As Above | Recommended particularly for 1st Chamber of Cement Mills in dry grinding process |
| BCL KROME – 28 | 26–30% | As Above | Certain applications in wet process of mineral grinding |
| BCL KROME – 21 | 20–24% | As Above | For mineral processing / grinding involving highly corrosive medium |
| BCL KROME – 2 | 1.5–2.0% | Min. 375 | Cement / Mineral Processing Industries |
