Dealing With Scat in Mill Processing - PumpEng Submersible Pumps

Inside these Sag/Ball mill are big steel balls that grind ore via an impact process. In simple terms, these hard metal steel balls get to the top of the rotating chamber and fall down crushing the ore being processed. It grinds it up into a compound to make processing easier. You'll find a similar process in sugar cane mills.

Mill Critical Speed Determination -

The "Critical Speed" for a grinding mill is defined as the rotational speed where centrifugal forces equal gravitational forces at the mill shell's inside surface. This is the rotational speed where balls will not fall away from the mill's shell. Mill Inside Diameter: Feet Metres. Enter the mill diameter inside the shell (excluding liners).

These magnets' main objective is to remove ball chips and worn out balls from the milling circuit. It is a simple concept that requires a short stainless-steel barrel and a permanent magnet around it covering an arc length of about 200 degrees on unidirectional mills. There is also a longer arc option for bidirectional ball mills.

scats Definition | Law Insider

scats means material in a ball mill or sag mill that has become rounded and no longer susceptible to additional size reduction. Basically, this material may be rejected from the grinding circuit for additional crushing because it contributes to higher energy consumption within the mill. Sample 1 Sample 2 Sample 3. Based on 8 documents.
