That is why the gearless drive of a grinding mill is one of the most crucial pieces of equipment in the concentrator and why it is subject to particularly high demands. siemens has provided about 80 simine gearless mill drives to the mining industry since.
The ball mill is powered by a fairly robust 12v dc motor salvaged from a junked printer. it had a pulley for a fine-toothed belt on it. it was left in place and it seems to drive the heavy round rubber belt well without slipping. the motor was mounted using screws on only one.
The drive and non-drive side indica te a phase difference of 182 o and considerable vibration on the non-drive side in the horizontal plane. this implies that the mill is doing a yawing.

The modernization project includes two 8 mw sag (semi-autogenous) mills and two 9.7 mw ball mills with dual pinion drives. the new drive systems are replacing the existing synchronous motors and direct converters for the sag mills and the drive systems of the ball.
These carbide ball end mills are general purpose, with a standard flute length (3xd), two cutting edges, and a center cutting full radius or ball on the end. the term general purpose means that the flutes have a 30 helical spiral and the od grind has a standard primary and secondary clearance.
This article from the analysis of the power consumption of the ball mill and the work characteristic of the motor, analyzes the fault reason of ball mill transmission equipment. the paper mainly deals with a side-transmission ball mill. the main fault is about the breakdown in the elastic rubber coupling of the transmission system. it is found from the analysis of the real cases and data that.
This system starts up the ball mill progressively until it reaches its rated speed, at which point the drive synchronizes the ball mill to the grid frequency to switch to fixed speed operation. after that, it is connected to the sag mill which works at a variable speed while remaining under control by the drive.
