### Grinding control strategy on the conventional milling

the control loop will attempt to add water to Cyclone 1 sump to achieve a particle size of 15 300 µm. If the hardness of the ore increases the particle size in the mill discharge from ball mill 1 will increase. With the same water addition to sump 1 the particle size of Cyclone 1 overflow will increase. This will decrease the ratio and hence Operation aim of ball mill grinding process is to control grinding particle size and circulation load to ball mill into their objective limits respectively while guaranteeing producing safely and stably. The grinding process is essentially a multi-input multi-output system (MIMO) with large inertia strong coupling and uncertainty characteristics.

### Ball Millan overview ScienceDirect Topics

Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.- ore and 25 steel. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones. The paper presents an overview of the current methodology and practice in modeling and control of the grinding process in industrial ball mills. Basic kinetic and energy models of the grinding process are described and the most commonly used control strategies are analyzed and discussed.
