Product Overview
This small high-speed grinder delivers rapid sample pulverization for demanding laboratory workflows. Powered by an 820 W motor spinning at 30,000 RPM, it transforms coarse materials into uniform fine powders in seconds. Its compact footprint and whisper-quiet operation—thanks to an integrated soundproofing barrel—make it an essential tool for labs where space and noise are critical considerations.
From pharmaceutical research to food quality control, this unit handles a wide spectrum of sample preparation needs. Laboratories in chemistry, agriculture, materials science, and education rely on its ability to process small batches of 10 to 100 grams with precise control over fineness. It handles everything from fibrous botanicals to brittle minerals, delivering consistent results for subsequent analysis or processing.
Built with a fully sealed 304 stainless steel grinding chamber and intelligent overload protection, this system ensures operator safety and material integrity. The precision-balanced blade assembly and direct-drive motor minimize vibration, contributing to long service life and reliable operation even under frequent use. Its robust construction reflects a commitment to engineering excellence, making it a trusted choice for demanding laboratory environments.
Key Features
- Whisper-Quiet Operation with Integrated Soundproofing: The noise-reduction barrel incorporates multi-layer acoustic damping materials, effectively lowering operational noise by up to 15 dB. This makes the unit suitable for open-plan labs, cleanrooms, and environments where multiple instruments operate simultaneously.
- Extreme Speed and Precise Fineness Control: The high-speed brushless motor spins at 30,000 RPM, delivering kinetic energy that rapidly fractures particles. Grinding cycles typically last only 1–3 minutes. By varying run time, operators can dial in fineness from coarse 20 mesh down to ultra-fine 200 mesh, enabling a single machine to serve many protocols.
- Compact and Portable Construction: Weighing just 3.7 kg and with a footprint of 190 × 250 × 190 mm, the grinder fits on crowded lab benches and can be easily stowed when not in use. Its low-vibration design eliminates the need for permanent mounting, allowing flexible deployment across workstations.
- Safety Overload and Thermal Protection: An intelligent onboard controller continuously monitors motor current and temperature. In the event of an overload or excessive heating, the system automatically shuts off power, preventing damage to the motor and protecting the operator. This feature significantly extends the service life of the grinder.
- Premium Stainless Steel Grinding Chamber: The grinding vessel is fabricated from high-grade 304 stainless steel, polished to a mirror finish for easy cleaning and minimal sample adhesion. The material is fully corrosion-resistant and certified for contact with food and pharmaceutical products. The sealed design ensures absolute dust containment.
- Versatile Material Processing: From tough fibrous botanicals like ginseng and licorice to hard minerals like quartz and feldspar, the high-torque motor and robust blade assembly handle a wide spectrum without stalling. It also processes heat-sensitive materials gently thanks to short cycle times.
- Precision Blade Geometry for Uniform Grinding: The blades are engineered with a compound angle that creates both shear and impact forces, maximizing size reduction efficiency while generating minimal heat. The vortex action keeps particles suspended, ensuring every particle receives the same amount of energy and resulting in a narrow particle size distribution.
- Tool-Free Operation and Easy Maintenance: The screw-top chamber cover and smooth internal contours allow the entire grinding path to be accessed without tools. Cleaning between samples takes merely a few wipes, preventing cross-contamination. Blade replacement, if ever needed, is a simple screw-off procedure.
- Minimal Sample Loss and High Recovery: The seamless chamber design, combined with the efficient blade sweep, leaves almost no residual powder after pouring. This is critical when grinding expensive or rare materials where every milligram counts.
- Efficient Motor Cooling: The high-speed motor is equipped with integrated cooling fins and an air circulation path that dissipates heat effectively, allowing for consecutive grinding runs without cool-down pauses. This ensures consistent performance even during high-throughput work.
