The Critical Speed is used for the determination of ball mill ideal operating speed. But for comparison rod mills would operate between 50 to 95 of the critical speed. The faster the mill speed the greater the wear on the rods and liners.

Ball mills are among the most variable and effective tools when it comes to size reduction of hard brittle or fibrous materials. The variety of grinding modes usable volumes and available grinding tool materials make ball mills the perfect match for a vast range of applications. Feed material medium-hard hard brittle fibrousdry or wet.

Planetary Ball Mills are used wherever the highest degree of fineness is required addition to well-proven mixing and size reduction processes these mills also meet all technical requirements for colloidal grinding and provide the energy input necessary for mechanical alloying.The extremely high centrifugal forces of a planetary ball mill result in very high pulverization energy and

Noise monitoring for optimal mill operation. Mining companies around the world continue to face the challenge of increasing productivity and reducing downtime. As part of its SAG mill control system Manta Controls developed the Manta Mic a robust and reliable acoustic analyser that prevents mill damage.

GrindingExpert™ automatically adjust feed rate mill speed and water addition to reduce upsets eliminate grind-outs and increase tonnage in SAG / ball mills. We constantly maintain desired operating conditions by monitoring bearing pressure power recycle pebbles mill density and mill

Optimization of mill performance by using online ball and pulp measurements Soon after a stop a mill is a dangerous place to enter for the personnel tasked with taking measurements or samples. Crash stops are difficult to handle. The mill and all feed streams should be stopped simultaneously but often they are stopped around about the same time.

In fact in the same application a Vertimill® has 50 less footprint than a ball mill. Lower operating cost. Vertimill® is an energy efficient grinding machine. They tend to grind more efficiently than for example ball mills with feeds as coarse as 6 mm to products finer than 20 microns.
