The (Open) Laboratory Ball Mill can be used for the amalgamation of table and flotation concentrates, by using one 4″ ball during the grinding action. A few slight changes provide for mounting an Abbe Jar on the driving shaft opposite the drum. This affords an excellent combination laboratory grinding unit.
Milling jars are scaled-down ball mills that are filled with grinding media and rotated using a jar rolling mill to reduce the particle size of the material. While both are commonly used for small size applications, options are available that can also be used for larger production opportunities. Long Roll Jar Mills
