What Is The Difference Between A Sand Mill And A Three-roller?

Nov 09, 2021

Nowadays, the mechanical equipment used in the chemical industry is becoming more and more diversified, and its uses are becoming more and more extensive. However, there is definitely a difference between professional and general; Pengyi Chemical Machinery is a professional manufacturer of sand mills and mixers. Usually, many people will ask about some issues related to sand mills and mixers. Today I will talk about the differences between sand mills and three-roll mills:

1. The difference

The three-roll machine is open grinding, and the three-roll machine is for grinding high-viscosity materials. The disadvantage is that the solvent is volatile and easy to form skin.

The sand mill is sealed and ground. The sand mill is suitable for wet grinding of medium, high and low viscosity, with a wide range of applications and high productivity.


2. Principle:

The working principle of the three-roll grinder: the three rollers arranged in the horizontal direction rotate at different speeds to squeeze, rub and shear each other to complete the grinding of the slurry.

The working principle of the sand mill: It is a device for solid-liquid phase dispersion and grinding of powdered materials. The conical design of the grinding cavity makes the grinding beads strongly impact the material at the feeding end. The grinding is obtained, so that a stable, fine-grained grinding effect is obtained.
