### Single & Double Stage Grinding Circuits

Closed circuit crushing is recommended for single stage grinding as there is greater control over size of feed going to the one ball mill. Open circuit crushing is advantageous when using two-stage grinding due to the ability of the rod mill to handle an over-size feed product.

### Closed Circuit Grinding VS Open Circuit Grinding

The simplest grinding circuit consists of a ball or rod mill in closed circuit with a classifier; the flow sheet is shown in Fig. 25 and the actual layout in Fig. 9. This single-stage circuit is chiefly employed for coarse grinding when a product finer than 65 mesh is not required,...

### Grinding in Ball Mills: Modeling and Process Control

Keywords: Ball mills, grinding circuit, process control. I. Introduction Grinding in ball mills is an important technological process applied to reduce the size of particles which may have different nature and a wide diversity of physical, mechanical and stone characteristics. Typical examples are the various ores, minerals, limestone, etc.

### Ball Mill - saVRee

Ball mills may operate in a closed-circuit, or open-circuit. Closed circuits return a certain amount of the ball mill’s output back to the ball mill for further size reduction. A typical closed system grinds the ore between two to three times.

The ball mill discharges to a sump where water is added before the slurry is pumped to the first cyclone (Cylcone 1). See Figure 1 for a schematic of the process flow. The slurry stream is classified at Cyclone 1 with the overflow going to the flotation circuit. Cyclone 1 underflow constitutes the fresh feed to the second milling circuit that runs in closed circuit with its own cyclone (Cyclone 2). Ball
