Optional peripheral discharge is for coarse grinding with minimum production of fines or slimes. Flexible for wet or dry grinding in open or closed circuit as a rod, ball or pebble mill and as an overflow or peripheral discharge rod mill. Advantages. The continuous grinding mills are designed for 24 hour per day continuous abrasive duty.
When the amount of ore in the mills was the same, no appreciable difference between batch and continuous open-circuit ball-mill grinding was found. This should be so, because the progression in particle size for the duration of a batch run would be expected to be the same as the progression from the feed to the discharge ends in a continuous run.

Apr 15, 2004· The characteristic differences between open- and closed-circuit grinding systems were examined via the use of a continuous vibration ball mill and a blade type classifier. For the same median diameter of the product, the rate of powder production in the closed-circuit is about 5% higher than that of the open-circuit.
AbstractComparison between anticipated and measured mean residence time (MRT) along with analysis of the shape of residence time distribution (RTD) curves provides the most useful and valid information about mixing properties within a ball mill operating at industrial scale. In this work, the RTD measurements were carried out for a primary ball mill in closed circuit with hydrocyclones at two ...

The larger the diameter is, the slower the rotation will be. Ball Mills are generally used to grind material ¼" and finer, down to the particle size of 20 - 75 microns. To achieve reasonable efficiency, the ball mills are to be operated in a closed system, with oversize particles continuously being re-circulated back to the mill and to be reduced.

C. continuous closed-circuit ball milling. It is arranged using the continuous mill with a gas or liquid classifying system. Air and feed enters through the opening at end of the mill. The classifier removes the smallest particles while the larger particles are recycled to the mill inlet for further size reduction.
The circuit comprises a SAG mill, 12 m diameter by 6.1 m length (belly inside liners, the effective grinding volume), two pebble crushers, and two ball mills in parallel closed with cyclones. The SAG mill is fitted with a 20 MW gearless drive motor with bi-directional rotational capacity.
