efffective condition monitoring for sag mill

Multotec is a leading specialist in rubber wear linings, offering full plant audits, installation and maintenance and condition monitoring services for your grinding mill liners. SAG Mill Liners Multotec SAG mill liners use rubber composite components to deliver superior impact and wear resistance in all semi-autogenous milling applications.

Since the mill is running continuously, no triggers or measuring conditions are applied. The parameters followed and trended are high energy shocks (HDm) and vibration velocity RMS. A moving average filter with 10 readings applied to both parameters has proven useful in avoiding false alarms caused by random high readings.

A condition monitoring solution visualizes the findings and communicates them to the users in a comprehensive form, say, as charts or diagrams. In case the situation deviates from the norm, a condition monitoring solution can also send an alert to a maintenance manager, notifying them about deterioration of equipment's condition. ...

But monitoring the condition of a grinding mill is not a trivial task. Variable process characteristics and a noisy environment creating interference with desired signals all contribute to making successful condition monitoring difficult. ... the ore itself is used in the grinding process. A SAG mill is a combination of a ball mill and an ...

CERAMIC LINED BALL MILL. Ball Mills can be supplied with either ceramic or rubber linings for wet or dry grinding, for continuous or batch type operation, in sizes from 15″ x 21″ to 8′ x 12′. High density ceramic linings of uniform hardness male possible thinner linings and greater and more effective grinding volume.

SKF supplied locally manufactured mill pinion assemblies including in-house designed bearing housings as well as a Taconite sealing solution to a longstanding customer in the local grinding mill sector intended for a 22x14 ft. SAG mill at a gold project in Russia.

Condition monitoring is a process where the condition of equipment is monitored for early signs of deterioration so that the maintenance activity can be better planned, reducing down time and costs. This is particularly important in continuous process plants, where failure and downtime can be extremely costly.

Traditionally, asset health is monitored in-person, in the field. This method requires many tools, many people and is time consuming. It leaves plants vulnerable to unplanned downtime and production loss, not to mention the loss of expertise that comes with personnel turnover.

A SAG mill is generally used as a primary or first-stage grinding solution. Attrition between grinding balls and ore particles causes grinding of finer particles.SAG mills are primarily used at gold, copper and platinum mines with applications also in …

Thus, with condition monitoring of the SAG mill behaviors employing vibration, acoustic and thermal signals, the relevant parameter can be diagnosed and monitored. Accordingly, the mill may work on its optimum conditions without the concern of any imminent problem like mill congestions and unplanned stops.
