The grinding circuit ( Fig. 1) used for the present study is part of a copper concentrator plant. The system consists of a ball mill, hydrocyclones, pulp sump and associated pumps and solids feeding conveyors. The feed, copper ore (from primary crusher, size 3 in) is fed into the ball mill by vibratory conveyors.

Chemical process industries are running under severe constraints, and it is essential to maintain the endproduct quality under disturbances. Maintaining the product quality in the cement grinding process in the presence of clinker heterogeneity is a challenging task. The model predictive controller (MPC) poses a viable solution to handle the variability. This paper addresses the design of ...

Mechanical milling is a promising route for production of submicron and nano sized silicon powders, but it is challenging to predict and control the product properties. In this study a metallurgical grade silicon quality was milled in a planetary ball mill and the properties of the powder were investigated as a function of grinding time, grinding bead size (20 mm, 2 mm, mm) and rotational ...

The grinding action employs much greater stress on the material than in a ball mill, and is therefore more efficient. Energy consumption is typically half that of a ball mill. However, the narrowness of the particle size distribution of the cement is problematic, and the process has yet to receive wide acceptance. Highpressure roll presses
