SDF Series High-Speed Laboratory Disperser & Sand Mill (200ml – 10,000ml | 0–10,000 RPM)
Product Overview & R&D Capabilities
The SDF Series Laboratory High-Speed Disperser is a versatile benchtop mixing, dissolving, and wet grinding instrument engineered for coatings, inks, paints, plasters, sealants, wall putties, and chemical formulation development. Designed to provide scalable shear data for commercial industrial high-speed dispersers (PDM series) and horizontal bead mills, the SDF series provides wide batch handling from 200 ml up to 10 Liters.
Powered by a permanent magnet DC (PMDC) brushless motor, the machine delivers high torque across an expansive 0 to 10,000 RPM speed window without carbon brush wear or electrical sparks. Its intelligent PLD control technology and 4-digit LED display provide real-time linear speed feedback, allowing laboratory researchers to easily calibrate tip speeds, prevent air entrainment, and switch effortlessly between Cowles dispersing discs and sand milling impellers.
Key Product Features & Engineering Highlights
1. Brushless Permanent Magnet DC Motor
Driven by a high-efficiency 0.55 kW permanent magnet DC motor with zero carbon brush consumption. Eliminates carbon dust contamination in high-purity test samples, delivers strong torque across all speed ranges, runs quietly (<60 dB), and produces zero electrical reversing spark interference.
2. 0–10,000 RPM Stepless Speed Regulation
Precision PLD control technology allows smooth, stepless speed adjustment from 0 to 10,000 rpm. A bright 4-digit LED digital display shows real-time motor speed, enabling laboratory formulators to replicate exact shear gradients and rheology curves accurately.
3. Dual-Function Dispersing & Wet Sand Milling
Equipped with modular, quick-change shaft terminals accommodating saw-tooth Cowles dispersing discs (Φ50 mm, Φ60 mm) and specialized sand milling discs (Φ45 mm, Φ60 mm). When charged with micro-beads in a vessel, it functions as a compact wet sand mill. For enclosed wet bead milling, explore our PZL laboratory horizontal bead mill.
4. Easy Disassembly & Rapid Cleaning
Tool-free quick-clamping mechanism and mirror-polished stainless steel shaft make washdowns simple. Researchers can execute rapid multi-color trial changeovers with minimal solvent waste. For immersion trials, compare with our PZM-L laboratory basket mill.
