Sand Mill by Polyc Machine

What is vertical bead mill?

A vertical bead mill is a dispersion machine that uses high-speed rotation of a vertical shaft with discs to agitate and grind materials into fine particles, typically through the impact of small grinding beads like ceramic or glass. It is used to disperse solid particles in a liquid to produce fine powders or suspensions with uniform particle sizes and is commonly employed in industries like paint, inks, and pharmaceuticals for tasks like homogenizing, dispersing, and achieving particle sizes in the sub-micron or nanometer range.  

Vertical bead mill working principle

Grinding and dispersion: The vertical bead mill uses ceramic, glass, or metal beads as the grinding media, which are agitated at high speed by a vertical shaft with attached discs. 

Particle size reduction: The material to be processed is introduced into the grinding chamber. The impact from the beads, the shearing action of the agitated media, and the energy input reduce the size of the solid particles within the liquid. 

Gravity and centrifugal force: Gravity pulls the material down, while the rotation of the rotor provides centrifugal force to move it upward, ensuring thorough grinding and a full cycle through the grinding chamber. 

Separation: After grinding, centrifugal force is used to separate the product from the grinding media, allowing the finished product to be discharged.
