I assume you are referring to a ball mill, since cyclone discharge recycle normally goes back to ball mill feed. I am less versed in ball mill grinding. Ball mills break rock by compression fracture, while SAG mills predominantly break by shear.
failure effect and criticality number or index calculation of each failure mode (Ahmad et al., 2012). Here first three steps are qualitative analysis and the fourth one involves quantitative analysis.
A ball mill is a type of grinder used to grind and blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.

These mills typically grind ROM ore in a single stage. A large example of such a mill was converted from a single-stage milling application to a semi autogenous ball-mill-crushing circuit, and the application is well described. This refers to high-aspect AG/SAG mills. Ball Charge Motion inside a SAG Mill
Hence the growing interest in the application of Root Cause Failure Analysis and we will deal with that later. In the meantime we will examine the diagnostic processes used to analyse vibration data to find the causes for excessive vibration and therefore the reasons for potential failure in a machine.

Figure 5. High–low wave ball mill liner Materials The selection of the material of construction is a function of the application, abrasivity of ore, size of mill, corrosion environment, size of balls, mill speed, etc. liner design and material of construction are integral and cannot be chosen in isolation.
th6 failure mode ohn reveals the true cause of failure. ?his procedure is compli- cated by the fact that one failure mode may initiate another. For example, corrosion in a ball race leaves rust-an abrasive-which can cause wear, resulting in loss of preload or an increase in radial clearance. ?he wear debris can, in a grease-lubricated bearing,

larger and larger mill sizes. It is thus no surprise that through our associa-tion with FL, we have been affiliated with the supply of some of the world's largest wet ball mills measuring 8.23m in Diameter and 13.10m long with an installed power of 18 650 kW, as well as the supply of SAG mills …
For ball mill work ribs are cast with the feed head liners to deflect the ball mass and minimize wear on the headliner itself. In grate ball mill work there are no discharge head liners. The discharge grates and grate assembly replace these parts.

drives the ball mill directly via the pin-ions of the two output shafts and re-duces the speed of the mill drive mo-tor to the pre-determined speed of the mill. The casing is of cast iron and hori-zontally divided into three sections. The torque split between the two pin-ions ensures that the total torque to the mill is always equally distributed

BALL MILL DRIVES, LOADED, OVERALL VIBRATION, SEPTEMBER 1A 1B • Above is a plot of the overall vibration levels at both the 1A & 1B ball mills when loaded. • Note how levels at 1A ball mill are higher than that at 1B ball mill for nearly every measurement.
Ball and roller bearing appear to be relatively simple mechanisms but their internal operations are relative complex. At extreme operating condition of heavy loading, very high speed, and very high or low operating temperature leads to early bearing failure.
