As the mill rotates, steel balls work to grind the materials. The mill rotates approximately once every couple of seconds. The grinding system uses either 'open circuit' or 'closed circuit'. In an open circuit system, the feed rate of materials is adjusted to achieve the desired fineness of the product.

KP1 was commissioned in 1968 and originally designed as a reef plant. It currently treats ore from SRDs. The plant comprises three-stage crushing, open-circuit rod mills for primary grinding and closed-circuit pebble mills for secondary milling. This is followed by cyanide leaching, filtration, zinc precipitation and smelting.

A typical structure of a closed-loop circuit for wet grinding consists of a ball mill, sump and classifier [10, 13, 33, 39] and it is schematically shown in Fig. 4.

Oct 11, 2019 In a closed mill circuit the oversize particles are returned from the post milling processes to be remilled whereas with an open circuit the process has no feedback loop. In dry grinding systems, the material from conventional crushing and screening operations is subject to coarse and fine grinding primarily in roller mills or ball mills to reduce the material to the necessary ...
