Abstract. Objectives: The aim of the study was to measure the dermal exposure levels of chromium dust during grinding of stainless and acid-proof steel parts.Methods: The potential dermal exposure of the body was measured with a patch sampling method and the actual exposure of hands with a hand-wash method. Simultaneously, personal air samples were also collected.

Aimed at the work conditions and the failure of the grinding ball in ball grinding, High chromium cast iron with the characteristics of long service life, high abrasion resistance and good shock resistance must be chose in the ball grinding . The best mixture ratio of chemical compositions was pointed out, and the production technological process by using die cast is introduced.

of the wear of low-chromium grinding alloys in laboratory mills was caused by corrosion. His data also showed that 'Underlined numbers in parentheses refer to items in the list of references preceding the appendi xes. grinding efficiency decreased as the amount of corrosion of the medium increased.

An effective protection of grinding mills from corrosion will improve the process performance and economics, enhance product quality, and increase the lifetime of mills and grinding media. Previous efforts to reduce grinding media consumption were focused on finding the most wear-resistant metal, e.g., high chromium alloys ( Liu et al., 2001 ).

High-Chrome media has a superior performance and creates steady milling conditions due to its low wear rate. For each specific alloy there is a constant hardness of all grinding media. This creates a positive influence in the down-stream process. high-Chrome media is suitable for both wet and dry ore applications in ball mills and tower mills.

The finish grinding process for cement materials uses ball mills with differently sized grinding balls. Because the grinding takes place through the impact and friction of the balls, balls with a high wear resistance are desirable and the materials of choice are the high-chromium white cast irons.
