Cryogenic Planetary Ball Mill Refrigerated Sample Preparation System High Energy Ultrafine Laboratory Powder Processing Equipment

Product Overview

This high-energy cryogenic planetary ball mill represents an advanced laboratory sample preparation solution engineered specifically for handling heat-sensitive, soft-to-medium hard, brittle, dry, or low-viscosity materials. By combining high-speed planetary motion with a heavy-duty 1200W active refrigeration unit, this system enables efficient comminution, mixing, and homogenization while maintaining operating temperatures between -10°C and -20°C. The integration of continuous thermal control resolves the persistent challenge of frictional heat accumulation, protecting vulnerable samples from thermal degradation, phase transformations, or undesirable melting during intensive grinding cycles.

Designed to satisfy demanding analytical requirements across materials science, pharmaceutical development, polymer analysis, and environmental testing, the unit processes raw feed sizes under 10 mm down to ultrafine discharge particle ranges between 0.1 and 20 µm. Operating with up to four 500 mL grinding jars simultaneously, this system provides versatile capabilities for both dry and wet grinding applications. Its ability to maintain cryogenic conditions transforms ductile polymers into brittle states, allowing researchers to achieve accurate, contamination-free microplastic extraction and uniform sample dispersion with exceptional repeatable consistency.

Built upon a heavy-duty chassis featuring a 304 stainless steel sun disc, reinforced soundproofing, and high-density thermal insulation, the equipment provides outstanding structural integrity and low-noise operational confidence. Intelligent control features—including digital speed adjustment, programmable interval timing, real-time temperature monitoring, and IP65-rated environmental sealing—ensure reliable performance under rigorous daily laboratory use. This system delivers an optimal balance of dynamic kinetic energy transfer and thermal control, providing research facilities with dependable sample preparation performance.
