Dry grinding, as in a jet mill, uses a single pass process; material enters the mill, passes through, and is expelled, reduced in size. In contrast, wet grinding uses a process of recirculation. The slurry is exposed to the grinding media over and over, for hours if necessary, until the desired particle size is achieved.
Abstract. 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.

Now it is a stockholding high and new technology enterprise to provide "Turn-key Solution for Mineral Processing Plant" including design and research, machine manufacturing, equipment procurement, management service, mine operation, mine materials procurement & management as well as industry resources integration.
The project economics study indicated a single grinding line. 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.
Ball mills have been the primary piece of machinery in traditional hard rock grinding circuits for 100+ years. They are proven workhorses, with discharge mesh sizes from ~40M to 200M. Use of a ball mill is the best choice when long term, stationary milling is justified by an operation.
1) wet grinding - dry grinding 2) open-circuit grinding - closed circuit grinding 3) single stage grinding - multiple stage grinding These methods are used in combination depending on the types and characteristics of the ore and the mixing ratio, taking into account the economic feasibility. A wet grinding system (Fig. 3) accompanies

The comminution product must be 80-90% passing 75 µm. Normally, the processes is employed when the gold content is ranging from 5 to 15 g/t. The grinding circuit is the first cyanidation circuit and the ball mill works as leaching drums. Once liberation is complete, the next step is to agitate the slurry to perform a complete dissolution of gold.
