What is a ball mill? A ball mill is a machine consisting of a rotating cylinder, a hollow shaft for feeding and discharging materials, and a grinding head.

What is a vertical roller mill? A vertical roller mill is a machine consisting of two symmetrical horizontal cylinders with a certain amount of abrasive material inside.
 

The differences between A Ball Mill And A Vertical Roller Mill:

 
1. Differences in working principles
 
~ The working principle of the ball mill is to make the abrasive and the material produces friction and collision in the cylinder through the rotation of the cylinder. 
 
~ The working principle of the vertical roller mill is to use the relative rotation of two cylinders to clamp, tear, rub, and other effects on the material between the cylinders.
 
2. Difference in grinding effect
 
~ The grinding efficiency of the ball mill is relatively low, and it is difficult to accurately control the grinding quality. 
 
~ The grinding efficiency of vertical roller mills is high, and the grinding quality can be accurately controlled.
 
3. Differences in application fields
 
~ Ball mills are widely used in cement, silicate products, new building materials, refractory materials, fertilizers, black and non-ferrous metal beneficiation, glass and ceramics, and other production industries. It is suitable for dry or wet grinding of various ores and other grindable materials. 
 
~ Vertical roller mill is mainly used for material grinding operations in cement, mining, chemical, and other industries, and can grind materials into a dispersed state of about 40-80 microns. It is particularly suitable for occasions with high requirements for grinding quality and large-scale production.
 
To sum up, there are significant differences between ball mills and vertical roller mills in terms of structure, working principle, grinding effect, and application fields. When selecting grinding equipment, comprehensive considerations should be made based on specific material characteristics, production needs, economic benefits, and other factors to select the most suitable grinding equipment.
