Ball mills are a low-speed application (typical rotational speed is 10-20 RPM), where bearing damage can be challenging to detect. Condition monitoring of the ball mill began in December 2016 and right from the start, the readings indicated potential damage on the output main bearing.
Fitzsimons confirms that Multotec Rubber recently introduced what he says is set to become the most affordable best practice mill liner profile condition monitoring system because it offers such high accuracy and immediate availability of information as such a reasonable cost.

Mills in Cement Plants, Power Plants and Mines. In industry, there are different types of mills, e.g. the vertical mill, the ball mill and roller mill. Usually mills are powered by one or more electric motors. For speed reduction one or more gears are used, which in turn may contain spur gear stages, bevel gear stages and planetary stages.

Condition monitoring (or, colloquially, CM) is the process of monitoring a parameter of condition in machinery (vibration, temperature etc.), in order to identify a significant change which is indicative of a developing fault.It is a major component of predictive maintenance.The use of condition monitoring allows maintenance to be scheduled, or other actions to be taken to prevent ...
Automated condition monitoring of mill ball size. Automated condition monitoring of mill ball size distribution and grate open area and therefore preventing the desireed top size product from exiting the millSAG mill throughput requires grate holes to remain open or else throughput is restricted Many grates in operation are pegged by grinding media to varying degrees of severity
Optimization of mill performance by using online ball and pulp measurements by B. Clermont* and B. de Haas* Synopsis Ball mills are usually the largest consumers of energy within a mineral concentrator. Comminution is responsible for 50% of the total mineral processing cost. In today's global markets, expanding mining groups are trying
