FM 306: SIZE REDUCTION AND SIEVING OBJECTIVE •To grind the given limestone material to a smaller size using a ball mill and to obtain the size distribution of the initial and the final mixture by sieving. •To estimate the energy required for the grinding operation. •To analyze the results using the available theories. INTRODUCTION
SAG mills have a power higher than 10 MW. Even ball mills have a power larger than 10 MW. For this reason, they have an important impact in energy consumption and in the operation of the power distribution system. Figure 1. Picture of a typical GMD system for a SAG mill Figure 2 presents the power circuit of a cycloconverter fed synchronous motor.

Selecting Inching Drives for Mill and Kiln Applications Glen Cahala Frank C Uherek, Principal Engineer - Gear Engineering Software Development Abstract The inching drive, also known as a barring or auxiliary drive, is an important component of any mill or kiln installation. .
CCVs are used for driving mine hoists, rolling mill main motors, ball mills for ore processing, cement kilns, ship propulsion systems, slip power recovery wound-rotor induction motors (i.e., Scherbius drives) and aircraft 400 Hz power generation. The variable-frequency output of a cycloconverter can be reduced essentially to zero.
mills can have correspondingly smaller sizes than usual. The material is dried in the ball mill. This system allows for the incorporation of several ball mills and permits separate pri-mary grinding of different components. The defined size of the feed material allows for optimum grading of the ball .
