Russell Mineral Equipment (RME) was established in 1985-86, and its logo was "RME" inside a grinding mill cross-section graphic. By 1990, RME consisted of a team of three: two mechanical engineers Peter Rubie and John Russell and draftsman, Doug Nield. RME's first mill relining machine a RUSSELL 6, was commissioned in August 1990 by MIM ...

Milling says: Avoid sudden changes in cross section. Although this is considered no more than ordinary good design practice, it is mentioned here because of its effect on the casting. Thin sections, which cool more quickly, can result in chill spots which are higher hardness than adjacent sections.

The Azzaroni equation indicates that the correct ball size for the 2.93 m mill is 81 mm. Years of experience show that a 76 mm ball grinds the coarse particles most effectively. Ball size distribution is governed by the wear law of the mill and by the wear characteristics through the cross-section of the balls charged to the mill.

The metal lifter bar design is generally a function of the grinding application and mill size. The cross section however must retain two critical dimensions. The first is that the lips or edges of the lifter that extend over the rubber plates must be kept at a minimum of 25 mm to provide adequate clamping of the liner plates by the lifter.

Some mills are compartmentalized with each subsequent section having a smaller ball size. The material can pass through to the proceeding section, but the balls cannot. This ensures that the smaller particles are attacked by the smaller grinding media. Ball mill is a versatile grinding mill and has a wide range of applications.
