Product Overview
This lab-scale horizontal sand mill delivers precision wet grinding for submicron and nanoparticle dispersion. Designed for both research and small-batch production, it combines robust engineering with user-friendly controls, enabling consistent size reduction from millimeters down to 0.3 microns. The system's versatile configuration supports a wide range of low- to medium-viscosity materials, making it an essential tool for formulation development and process optimization.
Ideal for industries such as pigments, dyes, inks, color pastes, coatings, pharmaceuticals, cosmetics, and advanced ceramics, this unit handles impact-friable materials with ease. Its modular design allows operation in intermittent batch mode for precise R&D or in recirculating continuous mode for higher throughput pilot batches, ensuring flexibility across various process requirements.
Engineered for long service life and minimal downtime, this equipment features high-purity zirconia ceramic wear components and SS304 fluid-contact surfaces, virtually eliminating metal contamination. The integrated pump system and quick-clean design simplify material changeovers, while variable frequency speed control and a robust drive system deliver the torque needed for demanding grinding tasks. Whether validating a new nano-dispersion formula or scaling up to production quantities, this system offers the precision, reliability, and durability that laboratory professionals demand.
