Sand mill screen mesh

The screen mesh in the nano sand mill is the core component for achieving efficient separation of solid liquid medium. It is mainly responsible for accurately separating the nano slurry that reaches the target fineness from the grinding medium (such as zirconium beads) during continuous dynamic grinding, while ensuring that the medium does not escape and the material does not block.

Its design and selection are crucial:

1. Separation principleMainly using precision physical gaps for interception, the gap width is usually 1/3 to 1/2 of the diameter of the grinding medium, ensuring that only qualified particle size slurry can pass through.

2. Key types：

   Static gap ring screenStacked with multiple wear-resistant rings to form precise gaps, the structure is sturdy, resistant to high pressure and high wear, and suitable for large-scale production.

   Dynamic rotor screen meshSynchronized with the rotor, it generates centrifugal force to prevent material from sticking to the mesh, has strong self-cleaning ability, and is more suitable for high viscosity and easily clogged materials.

   Wedge wire meshMade of trapezoidal sieve strips welded together, the gap is narrow inside and wide outside in a "V" shape, with excellent anti blocking properties.

3. core requirementsMust have bothHigh wear resistance(often using tungsten carbide, ceramics, and special alloy steel)Accurate gap precision(Determine the particle size distribution of the product) andExcellent anti blocking abilityIts performance directly affects production efficiency, product quality, and operational stability.
