Effects of the speed ratio on the efficiency of planetary mills

Nevertheless, by increasing the ball filling ratio or the friction conditions, due to the presence of the mill feed, the dynamics of balls changed to a cataracting regime. Finally, by insitu observations and using an image processing program, Rogachev et al [9] observed different types of ball movement depending on k.

Process engineering with planetary ball mills RSC Publishing

Planetary ball mills are well known and used for particle size reduction on laboratory and pilot scales for decades while during the last few years the application of planetary ball mills has extended to mechanochemical approaches. Processes inside planetary ball mills are complex and strongly depend on the processed material and synthesis and, thus, the optimum milling conditions have to be ...

Ball Mill vs SAG Mill: What's the Difference?

Understand the Difference Between Ball Mill vs SAG Mill. In conclusion, ball mills and SAG mills are both essential in the operation of any mineral processing facility. They both reduce particles in size by using different sizes of grinding media, and have differences in cost, efficiency, and use in regards to application.

Compare and Understand Rod/Ball/ImpactCrushing/Abrasion BOND Work Index

The Bond ball mill work index (Wi BM, or BWi) conducted from a feed size of approximately 2 mm to a product size on the order of 100 µm. The Bond rod mill work index (Wi RM, or RWi) conducted from a feed size of approximately 10 mm to a product size on the order of 1 mm. The Bond crushing (impact) work index (Wi C, CWi, LEIT or IWi) conducted ...

7 Major Differences between Ball Mill and Rod Mill

3. Different grinding medium. The Rod mill usually uses the steel rod with a diameter of 50100mm as the grinding medium, while the ball mill usually uses the steel ball as the grinding medium. The steel balls of ball mill are in point contact, while the steel rods of Rod mill are in linear contact, so their working ways are obviously different.

Comparative Analysis of Rod Mill and Ball Mill ball mills supplier

The reason why rod mill is called rod mill is that its grinding medium is steel rod, while the grinding medium of ball grinding mill is steel ball. Because the shape of the grinding media is different, the working mode has its own characteristics. When the steel rod is in motion, the gap between the rods is a regular long strip, which plays a ...
