Dry sample preparation mil
Optimize your grinding processes with precision particle size reduction for various materials, enhancing the consistency and quality of your production line.

Achieves Precise Grinding and Size Reduction
The POLYMIX PX-MFC 90 D from Kinematica AG is a laboratory blade grinding mill designed to deliver precision and consistency in the preparation of dry samples. This robust piece of equipment features a gearless speed control system and a wear-free three-phase motor, providing a speed range of 50 to 6000 rpm for versatile milling and grinding applications. As a solution widely utilized in pharmaceutical, chemical, and food industries, it efficiently processes a variety of materials including fine chemicals, nutraceuticals, and spices.
Key to its operation is the ease of changing grinding attachments and sieves, allowing for fast adaptation to different sample types, whether brittle, stringy, or fibrous. This flexibility is complemented by its safety features, such as dust-protected switches, automatic motor stop upon chamber opening, and built-in overload protection, ensuring user safety and equipment longevity.
Built to handle abrasive and hard materials with Mohs hardness up to 6, the mill delivers sub-40µm particle sizes ideal for precise quality control. Compliance with IEC and EN standards ensures reliable integration into lab settings, while its compact, bench-top design supports easy cleaning and maintenance, enhancing workflow efficiency.
