The LRMIX 55L Horizontal Sand Mill is a pin-type wet grinding machine built for paint, ink and pigment paste producers who need consistent fine grinding down to 5 microns. Driven by a 37kW motor and fed through a Type 65 pneumatic diaphragm pump, with a fully explosion-proof motor and control cabinet, it’s engineered for safe, continuous production.
A Horizontal Sand Mill Built for Fine Wet Grinding
This sand mill uses a pin-type grinding rotor driven by a 37kW motor, generating intense impact and shear between the grinding media and the material to reach a fineness of 5 microns. A Type 65 pneumatic diaphragm pump feeds the mill at stable, adjustable pressure suited to varying viscosities, while the explosion-proof motor and control cabinet make it safe for continuous production with solvent-based materials.
Common Challenges in Fine Grinding for Paint & Ink
Standard mills struggle to consistently reach below 5 microns, affecting gloss and hiding power.
Gear pumps handle high-viscosity or particle-laden slurries poorly, causing feed fluctuation or blockage.
Continuous grinding of solvent-based materials generates heat; standard electrics risk ignition.
Weak separation designs wear out media quickly and let it contaminate the finished product.
Why Choose This Horizontal Sand Mill
The pin-type rotor delivers high-frequency impact and shear for efficient, consistently fine grinding.
Stable, adjustable feed pressure adapts to varying viscosities and reduces blockage downtime.
A high-power motor ensures stable output during long continuous production runs.
Motor and control cabinet are explosion-proof rated, suitable for continuous grinding of flammable materials.

FAQ
How fine can this sand mill grind?
The pin-type design can grind down to 5 microns.
Why use a pneumatic diaphragm pump instead of a gear pump?
Pneumatic diaphragm pumps handle particle-laden, high-viscosity slurries more reliably, reducing feed instability and failures.
Is it safe for solvent-based materials?
Yes, both the motor and control cabinet are fully explosion-proof.
Can capacity be customized?
Yes, chamber volume and pump specification can be customized to your throughput needs.
