BBD was used in the present study and particle size (Y 1), PDI (Y 2), and zeta potential (Y 3) were selected as the CQAs. The independent variables taken into consideration were size of balls (A), concentration of stabilizer (B), amount of drug (C), and milling time (D). The speed at which the ball mill rotated was kept constant.
A statistical Box-Behnken Design (BBD) of experiments was performed to evaluate effects of individual variables and their interactions on wear rate of grinding ball mill used in phosphate industry. The variables examined in this study included grinding time, solution pH, rotation speed, mill crop load, and solids percentage.
Phosphorus slag (PhS) is the base aluminosilicate raw precursor in this work that is supplied from the phosphoric acid production plant located in the southeast of Tehran province in Iran. The granular slag is ground in a laboratory ball mill to a specific surface area of 0.4 m 2 /g. The average particle diameter of the ground slag is 13 µm.

The gel was obtained by centrifugation (speed: 8000 r/min; time: 3 min). The ungrafted hydrolysis product of KH-570 was removed by washing with 50% ethanol solution several times. After vacuum drying at 40 °C for 24 h and grinding with a ball mill, fluffy KH-570 modified nano-silica was obtained. 2.1.3. Preparation of the PAM/MNS composite gel
Ball milling, a shear-force dominant process where the particle size goes on reducing by impact and attrition mainly consists of metallic balls (generally Zirconia (ZrO2) or steel balls), acting as grinding media and rotating shell to create centrifugal force.
