Pressure Control In Ball Mill

Control strategies can now factor in volumetric loading, charge toe angles, and steel-to-liner impacts in the decision tree along with bearing pressure, recycle pebbles, and mill power. Compromising accuracy when selecting an acoustic sensor for your girding circuit will only compromise the integrity of the control system for future improvements.

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 181m. 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

Can A Ball Valve Be Used As A Control Valve

If you must use a ball valve to control your process, you might want to consider different types of ball valves depending on your application. A trunnion or v-port ball valve will perform better and allow for more accurate adjustability in certain scenarios. Trunnion ball valves have an additional mechanical anchoring of the ball at the top and ...

A Fuzzy Control Method For Ball Mill System Aased On Fill

Jun 19, 2009018332Abstract Aiming at the disadvantage of ball mill system control, a new control algorithm based on fuzzy logic control is proposed. Firstly, the dynamic characteristic of ball mill pulverizing is given. Secondly, the control method is introduced. For mill level control loop, by the fuzzy decision making, the mill fill level is represented by the out temperature and the differential pressure.
