High Cr Alloy Steel Casting Of Lifter Bar , High Hardness And Wear Resistant EB6066
Quality High Hardness and Wear Resistant High Cr Alloy Steel Casting of Lifter Bar
Mill liners protect the cylindrical structure of the mill from wear.Thus the main wear parts in these mills are
the balls themselves, and the liners. The balls are simply "consumed" by the wear process and must bere-stocked,
whereas the liners must be periodically replaced.
The ball and tube mills are low-speed machines that grind the coal with steel balls in a rotating horizontal
cylinder. Due to its shape, it is called a tube mill and due to use of grinding balls for crushing, it is called a
ball mill, or both terms as a ball tube mill.
