Before highenergy ball milling, a comminution process was necessary to break up the arcmelted buttons. This preliminary step was conducted in a vertical mill Tecnal TE350 using a stainless steel vessel with a volume of 235 ml and a singlesphere of mm (1 ¼ inch) diameter for a milling time of 5 min for obtaining the pristine powder condition.

Ballmilling is a lowcost and green technology that offers mechanical actions (shear, friction, collision, and impact) to modify and reduce starch to nanoscale size. It is one of the physical modification techniques used to reduce the relative crystallinity and improve the digestibility of starch to their better utility.

Wet ball milling. The main goal of ball milling method is to reduce particle size to a target range. It has been widely used for transforming powders into fine particles (also known as comminution), inhibiting the aggregation of fine particles, deagglomerating powdered materials and blending materials by using impact and friction forces.

Before ballmilling the hybrid adsorbents, biochar, AC, and Fe 3 O 4 were milled for 7 h, and their median diameters (D50) decreased significantly within initial 1 h, and reached about μm after 2 h of milling (Fig. S1). Similarly, the D50 values of biochar/Fe 3 O 4 and AC/Fe 3 O 4 after 2 h of milling were also about μm, and kept almost constant with increasing milling time (Fig. 2).

As the name suggests, the ball milling method consists of balls and a mill chamber. Therefore over all a ball mill contains a stainless steel container and many small iron, hardened steel, silicon carbide, or tungsten carbide balls are made to rotate inside a mill (drum). 2. The powder of a material is taken inside the steel container.

The process for preparing composites by ballmilling method is relatively complex. Ballmilling time and speed, grinding balls and ballmaterial ratio, process control agent and the type of ball mill are all parameters that require careful consideration prior to experimentation (Li et al., 2009; Ambika et al., 2016; Wang et al., 2022).
