Laboratory Nano Sand Mill Wet Grinding Dispersing Machine for Fine Particle Size Reduction

Product Overview

This laboratory nano sand mill is an advanced wet grinding and dispersing system engineered specifically for high-precision material processing at the nanometer scale. Designed to reduce liquid suspensions and low-to-medium viscosity slurries down to a particle size range of 1 to 50 nm, this equipment integrates grinding, dispersing, and mixing into a unified, highly automated platform. By leveraging a high-energy transfer mechanism driven by friction, impact, and high shear forces, the system achieves uniform particle size distribution across diverse chemical and material research workflows.

Built for versatility in demanding research and development environments, the unit operates seamlessly in both batch and continuous recirculation modes. Target applications span advanced energy materials, electronic ceramics, fine chemicals, inks, coatings, and pharmaceutical suspensions. The overall architecture focuses on process repeatability, thermal stability, and strict protection against sample contamination during high-intensity milling operations.

Engineered with robust industrial-grade components, the machine features high-purity zirconia contact surfaces to preserve sample purity during aggressive grinding. Integrated liquid cooling circuits and intelligent variable frequency speed control ensure reliable performance during extended grinding runs. Researchers and process engineers can depend on this system to transition seamlessly from preliminary benchtop experiments to standardized, repeatable production processes.

Key Features

• All-Zirconia Sample Contact Surfaces: The 1000 mL grinding chamber, internal grinding rod, chamber cover, and grinding media (0.1–1 mm) are constructed from high-purity zirconia, eliminating metallic contamination and ensuring chemical compatibility with sensitive suspensions.
• High-Energy Triple-Action Milling: Utilizes a dynamic combination of intense frictional forces, mechanical impact, and high shear stress to achieve rapid size reduction down to the 1–50 nm range.
• Dual Recirculation and Dispersion System: Features an integrated sample recirculation system delivering a flow rate of 8 L/min paired with a 2500 mL high borosilicate glass sampling cup and a dedicated 1800 rpm micro disperser mounted on a 304 stainless steel stand.
• Advanced Variable Frequency Drive: Driven by an 1100 W motor with VFD speed control reaching up to 2000 rpm, offering continuous, intermittent, and forward/reverse alternating grinding cycles for optimized energy input.
• Integrated Closed-Loop Liquid Cooling: Enclosed in a 304 stainless steel cooling jacket with a quick-detach coolant reservoir, the cooling circuit effectively dissipates process heat to maintain temperature-sensitive samples within target limits.
• Flexible Programmable Operation: Equipped with comprehensive process timing, variable speed adjustment, automated circulation control, and active sampling capabilities for complete control over process parameters.
• Industrial Ingress & Quality Certification: Enclosed in a compact 470 × 470 × 290 mm housing rated to IP65 protection standards and certified under CE and ISO9001 quality management systems.
