Sand mill is a kind of equipment for material grinding, widely used in coating, ink, chemical, food and other industries. Its working principle mainly involves grinding, dispersing and mixing of materials under the action of abrasive media. The following is a detailed explanation of the working principle of the sand mill:

Structure: The sand mill is usually composed of silo (feed area), grinding chamber, separator, discharge port and drive system. The grinding chamber is filled with grinding medium (such as sand, glass beads or other grinding media).

Material feed: The material to be ground enters the grinding chamber through the feed port. During this process, the material is in full contact with the mill.

Grinding process:

Grinding motion: The grinding medium moves rapidly under the action of the drive system. The motion of the mill can be high speed rotation, vibration or agitation.

Shear and impact: The moving grinding medium exerts shear force and impact force on the material, so that the material is subjected to strong grinding effect in the grinding chamber. In this process, the particles of the material will be continuously dispersed and refined.

Dispersion and mixing: With the grinding process, the particles in the material are gradually refined and uniformly dispersed under the action of the grinding medium. This process can also make different materials mixed with each other to a certain extent.

Discharge: After a certain period of grinding, the refined material is discharged through the discharge port. The discharge port is usually equipped with a separator to prevent the grinding medium from being discharged along with the material.

Recycling: In some sand mill designs, the discharged material can be recirculated back into the grinding chamber to continue grinding to improve efficiency.

Cooling system: During the long grinding process, the material and the grinding medium will generate heat, so some sanders are equipped with cooling systems to keep the temperature stable during the grinding process and prevent the material from deteriorating due to overheating.

In general, the sand mill through efficient grinding movement, so that the material in a short time to achieve fine and uniform dispersion of the effect, is an indispensable equipment in many industrial fields.
