For ball mills, ball charge level, lining and diaphragm condition must be monitored and maintained in nearoptimum condition. Mill stops, defined as mill motor off, and measured by mean time between failures (mtbf), are frequently poorly recorded and the resolution of underlying issues is frequently not addressed.
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. Cooling, heating cryogenic grinding.

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. Some compression fracture does occur, but, it is not the major comminution mechanism.
The mill rotor bearings, which are mounted in the steel housing, are two (2) cylindrical roller bearings, NU 316 ECM/C3, and one (1) grooved ball bearing, SKF 6316 C3. The bearings have failed several times over a period of two (2) years. Before this time, the mill had no recorded bearing failures (as confirmed by the CMMS).
Steel Ball Mills Lined Ball Mills. Particle size reduction of materials in a ball mill with the presence of metallic balls or other media dates back to the late 1800's. The basic construction of a ball mill is a cylindrical container with journals at its axis. The cylinder is filled with grinding media (ceramic or metallic balls or rods ...
Over the years, alternative procedures to the Bond grindability test have been proposed aiming to avoid the need for the standard mill or to reduce and simplify the grinding procedure. Some of them use the standard mill, while others are based on a nonstandard mill or computation techniques. Therefore, papers targeting to propose a better alternative claim to improve validity, to reduce test ...
Scheduled offline maintenance or failure of one of the Ball Mills (or its ancillary equipment) causes a 50% loss of milling production. Most of the maintenance results from timedependent failure mechanisms ( wear, corrosion or fouling). The crushing circuit has a mean running time to failure of 6 months.
Case Studies Case Study 1 The problem A centre circular flange joint on a Ball mill, had breaking flange bolts and a weeping joint. The mine was experiencing stoppage on an almost daily basis, resulting in considerable lost production.
HPGR test results published by Grier (1992) on gold ores from the Mt. Todd project showed significant energy savings for a HPGR/Ball Mill circuit as compared to a SAG/Ball Mill plant. By adding a Polycom highpressure grinding roll, the throughput of existing plants can be increased by as much as 150% while simultaneously reducing the power ...
Failure analysis Fatigue cracking Ball mill Structural steels Welded joints 1. Introduction Grinding ball mills are rotating equipments commonly present in iron ore mining plants, which use steel balls to reduce the ore particle size and prepare the ore pulp for subsequent concentration process.
Ball mill is a typical representative of mineral processing equipment in mining machinery. This paper was concerned with the deterioration process of monitoring of gear, including the change of vibration and the spectrum characteristics. The common failure causes of gear and the methods of monitoring and diagnosis are given, which is of significance for reducing accidents, reducing maintenance ...
Each failure leaves its own special imprint on the bearing. Consequently, by examining a failed or damaged bearing, it is possible in the majority of cases to establish the root cause and define corrective actions to prevent a recurrence. This publication is intended to provide a basic understanding of bearing failures and failure analy sis.
It would be unreasonable to dismiss the viewpoint of a mill designer on the design of ring motors just because the mill structure is relatively much simpler than the motor. So, let us look at the design validation of mills. Svalbonas [2] presents strain gauge measurements from a mill in a paper dated 1979.
