Horizontal sand mill for paint is core wet grinding equipment dedicated to paint and coating production. It efficiently disperses and crushes pigment agglomerates to get uniform fine particles, improving paint gloss, color saturation and stability. Built with stainless steel chambers and circulating cooling systems, it avoids material overheating during continuous work. This horizontal sand mill for paint features tight sealing, low leakage and easy maintenance, supporting stable mass production of industrial, architectural and decorative paints with reliable long-term performance.
Extreme Flow Rates (Up to 1200 L/h)Optimized for Paint Resins & PigmentsHigh-Efficiency Dynamic SeparatorThe ZLWD horizontal sand mill for paint utilizes disc-type dispersion grinding for medium-low viscosity materials (e.g. standard liquid inks, carbon black, industrial coatings, automotive paints, latex paints, titanium dioxide) — all common applications of a sand mill in paint industry. Featuring a single-layer cooling jacket for reduced energy consumption and a gap-type dynamic separator with self-cleaning capability to prevent clogging and ensure durability. Grinding media selectable from 0.6-2.5mm, with customizable PU or ZrO2 chambers/discs to eliminate metal contamination. Comprehensive product range and proven technology guarantee long-term operational stability.
The Engine of Mass Paint Production
Producing high-volume architectural emulsions, marine coatings, or industrial paints requires equipment that can handle relentless, continuous operation without overheating the resins or clogging the discharge screens.
The ZLWD series horizontal sand mill is purposefully engineered as a sand mill for paint mass production. With grinding chamber volumes reaching up to 100 Liters and production capacities hitting 1200 L/h, it utilizes an advanced dynamic gap separator to ensure smooth, blockage-free continuous flow. As a high-capacity sand mill in paint industry applications, it delivers absolute sub-micron uniformity, ensuring your paints achieve maximum hiding power and gloss.
Paint-Optimized Flow Dynamics
The horizontal chamber layout of sand mill in paint industry prevents grinding bead compaction, allowing continuous pumping of medium-viscosity paint slurries with minimal pressure drop.
High-Volume Dynamic Separation
Employs a highly precise, self-cleaning dynamic rotor gap that effectively holds back Zirconia micro-beads while letting large volumes of finished paint flow through seamlessly, ideal working structure of sand mill for paint.
Over-sized Cooling System
Since high-speed milling generates significant friction, the ZLWD features an enlarged water-cooling jacket surrounding the entire chamber and mechanical seal, protecting heat-sensitive paint binders from thermal degradation.

Mass Production PaintsArchitectural wall paints, water-based emulsions.
Industrial CoatingsEpoxy primers, anti-corrosive marine paints.
Pigment PastesHigh-throughput colorant dispersion.
While both are horizontal mills, the ZLWD horizontal sand mill is specifically calibrated with a different rotor-to-chamber ratio and a larger separation gap designed to maximize flow rates (throughput) specifically for the standard paint and coating industry.
No. The ZLWD horizontal sand mill operates at high speeds (620-800 rpm) tailored for flowing paints. For high-viscosity, non-flowing pastes, you must use our low-speed, high-torque ZLWG series.
Sand mill in paint industry delivers ultra-fine particle size, uniform dispersion. This sand mill in paint industry cuts processing time, stabilizes paint gloss and color consistency for water-based and solvent coatings.
This sand mill for paint handles acrylic, epoxy and latex paints well. It works with inorganic & organic pigments, low-viscosity to medium-viscosity coating raw materials without agglomeration.
Clean the grinding chamber after daily paint production, check grinding media wear regularly. Replace sealing parts timely to avoid paint leakage and ensure stable long-term operation.
