Grinding jars and media for planetary ball milling can be obtained in a variety of different materials, including stainless steel, agate, tungsten carbide and various ceramic materials. For wet grinding, jars and media made from yttrium stabilized zirconium oxide (ZrO2) will produce the best results with minimal sample contamination.
The rod mill is suitable for fine crushing and coarse grinding of ores with a Mohs hardness of 5.5-12. Such as: gravity separation or magnetic separation of tungsten ore, tin ore and other rare metal ores; when processing softer materials, rod mills can be used instead of short-head cone crushers for fine crushing operations.

We grind a sintered tungsten ball of about 32Rc. Non of our operators have any experience in ball grinding and very few have very limited manufacturing experience. Our tolerances are loose (+/- .002")and do not need a finish grind or lap. We have a process in place. This process though, I believe his cause for our problems.
Special consideration is given to the friable nature of the tungsten by using Crushing Rolls and the quick pass grinding offered by the Peripheral Discharge Ball Mill. Previous experience in the concentration of tungsten ores, indicates that the fine sizes carry the tungsten losses.
Milling and grinding media are designed for ball milling and the grinding of bulk powder or granular materials into finer powder forms. Ceramic bead, hard metal shot, carbide balls, and other ball-shaped media are used. The hardness of the powder or bulk material to grind determines the selection of the media material.

The grain refinement process and mechanisms of tungsten powder during ball milling are explored based on different ball milling time. From the results of scanning electron microscopy (SEM), the model for ball milling process is proposed to include four stages: welding stage, squeezing stage, fracturing stage and dynamic balance stage.
18th,July.2019The Planetary ball mills are the most popular mills used in fine grinding of soft to hard, tough, brittle and moist materials. The grinding media have considerably high energy, because grinding stock and balls come off the inner wall of the grinding jars and the effective centrifugal force reaches up to 20 times gravitational acceleration.
