Light Stir Ball Mill

The Light Stir Ball Mill is a type of ball mill used in laboratories to grind materials. It is best suited for small to medium-sized research projects as well as pilot production. It is suitable for a variety of applications such as sample preparation, chemical and abrasive material reduction, and bio-energy conversion.

Variables affecting the grinding performance

Many factors influence the performance of a Lab Light Stir Ball Mill. The final outcome of the grinding process is influenced by variables such as media size, feeding size, and speed. Furthermore, the rheological properties of the slurry are critical.


Several studies have been conducted to investigate the effects of various variables on the grinding efficiency of a ball mill. One of these studies investigated the relationship between feed particle size and specific energy consumed during the grinding process. However, it was discovered that the actual results could deviate significantly from the predicted results.


To develop a more realistic model, a better understanding of the motion of the media contents within the mill is required. Until then, a combination of experimental and numerical tests is the best approach. The results of some of these studies will be presented in this article, along with an examination of how operating conditions affect the final outcome of the grinding process.


The parent particle size determines the breakage distribution. Breakage distributions become narrower as the size of the parent particle decreases. Breakage distributions become more skewed as parent particle size increases.


Breakage rates rise in tandem with mill rotational speed. As a result, the breakage distribution resembles the feed PSD more closely.


Another important factor influencing the final product is media load. Increasing the number of media elements in the mill reduces collision frequency, but it also increases impact and wear. As a result, it is best to strike a balance between media loading and grinding power.


The P80 obtained, or the percentage of particles passing the given size, is a proxy for the particle surface area. This parameter is related to both the ore feeding size and the degree of grinding. Increasing the surface area of the particles improves the grinding process's effectiveness.


Finally, the Bond work index is a formula that estimates the amount of energy needed to grind a short ton of solids. It is measured in kWh/short ton.
