Stainless Steel Bead Milling Machine Cold Grinding Machine

Product Description

Bead mills are grinding and dispersing machines designed to grind and/or disperse particles down to the micro and nano scales. Beads (grinding media) inside the grinding chamber are agitated by rotating the shaft and the particles are ground and/or dispersed by the collision and shear force of the beads. The outlet of the grinding chamber has a filtering structure to separate beads from particles, retaining beads inside the chamber and enabling continuous production of fine particles.
The bead mill has a variety of product concepts according to the equipment structure, material material, grinding fineness, application field, etc., such as: vertical sand mill, horizontal sand mill, nano sand mill, sub-nano sand mill, micron sand mill, nano ceramic sand mill and so on.
Working principle
The working principle of the sand mill is that the grinding medium and the material in the fixed cylinder are stirred by the high-speed rotating dispersion disc, so that the solid particles in the material and the grinding medium produce strong shear, erosion, collision, to achieve the purpose of grinding and dispersion.
Features
Dry Bead Mills
Dry bead mills employ a system to produce fine particles in air or inert gas atmosphere. With beads of relatively large diameter inside, large and coarse particles can be ground easily.
There are two types of dry bead mill operations: continuous or batch operations.
Wet Bead Mills
Wet bead mills employ a system to produce fine particles in liquid. As the minute beads inside are agitated at high speed, the machines are capable of producing particles down to the size.
There are three types of wet bead mill operations: circulation, pass, and batch operations.
Dry processing is optimal for micro-size particles and wet processing is suitable for nano-size particles.
As beads with a relatively large diameter are employed in dry bead mills, large and coarse particles can be readily ground by vigorous agitation. As wet bead mills employ minute beads, finer particles can be produced with strong shear and friction force caused by agitating beads at high speed.

FAQ
1. What is a bead(sand)mill machine?
A sand mill is a machine designed for the ultra-fine grinding of solids in liquids, using small grinding media made of materials like glass, ceramics, or steel to achieve particle size reduction.
2. How does it work?
Equipment operates on the principle of kinetic energy and collision. The beads within the mill move rapidly, colliding with each other and the particles in the mixture, leading to a reduction in particle size.
3. What's the difference between a horizontal and a vertical sand mill?
A horizontal machine has a horizontally oriented milling chamber, while a vertical bead mill's chamber is vertically aligned. The movement of beads differs in both setups, with horizontal mills having side-to-side movements and vertical mills having up-and-down bead movements.
4. Why are bead machines used in industries?
Equipment is favored for their efficiency in achieving fine particle sizes, versatility in handling different materials, and producing consistent results. They find applications in industries like pharmaceuticals, paints, cosmetics, and nanotechnology.
5. Are there any alternative machines or methods to bead mills?
While sand grinders are preferred for ultra-fine grinding, there are other methods and machines like blade-based grinders or high-pressure homogenizers. However, for certain applications, especially where nano-sized particles are required, bead mills are often the go-to choice.
6. What are the grinding media made of?
The grinding media can be made of various materials, including glass, ceramics, and steel. The choice of bead material can depend on the type of substance being milled and the desired outcome.
