Effect of Water & Density on Grinding Mill
As you increase the volume of the through put, the time that the ore has to react to the grinding media is lessened. As you add ore to the mill you are also adding WATER and changing density which affects the slurry rheology and workings of the grinding action inside that mill. This water is one- of the main controls that you have over your grind.

What is a Rod Mill?
A rod mill is a type of ore grinding equipment used to grind materials into fine powder. Unlike ball mills, rod mills use long steel rods instead of balls as the grinding medium. Rod mills are ideal for breaking down materials such as minerals and ores. In this article, we'll provide a comprehensive guide on what a rod mill is, how it works ...

Stirred Media Detritors (SMD)
Stirred Media Detritor (SMD) is a fluidized media grinding mill. It utilizes the rotational energy of the impeller arms to impart a high-energy motion to the media and slurry mixture inside the mill. This results in particle-to-particle shear and compressive forces that produce the desired grinding mechanism for fine grinding. Lower capital cost.
