Thus, the motion of a simple pendulum is a simple harmonic motion with an angular frequency, ω = √ g L ω = g L, and linear frequency, f = 1 2π√ g L f = 1 2 π g L. The time period is given by, T = 1 f = 2π√L g T = 1 f = 2 π L g. Performing dimension analysis on the right side of the above equation gives the unit of time.

Keywords: Ball mills, grinding circuit, process control. I. Introduction Grinding in ball mills is an important technological process applied to reduce the size of particles which may have different nature and a wide diversity of physical, mechanical and chemical characteristics. Typical examples are the various ores, minerals, limestone, etc.

What is a 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.

This can reduce the energy consumption and the use cost of the ball mill. To make the milling more efficient, we must first be acquainted with the factors. They are mainly the ball mill structure, the rotation …
