Particle morphology control for spherical powder
The smaller the ball, the more abrasion and attrition it produces. With a smaller ball diameter in a given volume, the number of balls and the contact surface increase, resulting in faster milling. ... The ball milling process has become a spherical morphological shape that is dependent on smaller balls and the effect of rotation speed, …
What is a Ball Mill? | Economy Ball Mill
A ball mill is a type of grinder that uses metal balls or other grinding mediums to reduce the size of various materials. The material to be ground is placed in a cylindrical container that spins on its axis. The metal balls or grinding media inside the container hits the material and breaks it down into smaller particles.
Attrition scrubbers
Attrition scrubbers are used to scour particulate surfaces, removing undesired materials and breaking down clays – cleaning and desliming the particles prior to other treatment processes. It is the friction between the particles, created by turbulence and supplied by the machine's impulsion, that provides the highly efficient cleaning action.

What is a Ball Mill Explained: In-Depth Guide
The working principle of a ball mill is based on the premise of impact and attrition. The rotation of the shell lifts the grinding media and then releases it to impact the feed material. This results in smaller particles of the ore particles. On the other hand, this process continues until the size of the ore particles reaches the desired size.
