The ball mill process is a mechanicalchemical process that uses mechanical force to induce the chemical and structural change of certain materials (Amusat, Kebede, Dube, Nindi, 2021). A mechanical mill is a type of grinder used to grind and blend a bulk material into extremely fine nanosize powder using different sizes of milling balls.

Tertiary grinding is the ultimate breaking down of crumb rubbers to obtained a fine powder, for these 100% conversion in a single unit can be achieved with wet grinding techniques. Generally, coarse size reduction is achieved by crushing and shredding operations and finer grade size reduction is achieved using the grinding method.

Grinding is an ageold technique of particle size reduction to produce powders that can be used as intermediate or end products. Grinding aims to reduce the size of the particle by mechanical means such as impact, compression, shear, and cutting (Sahay and Singh, 1996).Hammer mill, plate mill, ball mill, pin mill, roller mill are commonly used grinding equipment for spice (Balasubramanian et ...

For the preparation of small quantities of powder many types of mill are available but, even so, the ball mill is frequently used. For the grinding of the largest quantities of material however, the ball, tube or rod mill is used almost exclusively, since these are the only types of mill which possess throughput capacity of the required magnitude.
