Retsch centrifugal ball mills grind and mix soft, medium-hard, hard and brittle materials. Dry and wet grinding in suspension is possible. Centrifugal ball mills are used in the field of analytical chemistry, pharmacy, biology, mineralogy, geology, paints and enamels, ceramics, nuclear research, environmental protection, etc. A multitude of accessories makes for ideal matching to the most diverse applications, be they in research, developement or quality control.
Advantages
- Great ultimate fineness, down to into the micron range
- Fast no loss grinding, dry and wet
- Time and speed displayed digitally
- Memory keys for 3 working programs
- Automatic direction reversal is standard
- Re-set lock to secure the parameters selected
- Universal application with a wide range of accessories
- Stable smooth operation with adjustable balancing masses
- High reproducibility due to speed control (continuous adjustment of actual value to set value)
- 2 year warranty, CE marked
The grinding jars in the centrifugal ball mills move in a horizontal plane. Speed is continuously adjustable from 100 to 580 rpm. During the entire grinding process, an electronic speed control compares the actual speed to the preset value and keeps it constant. The centrifugal forces which are generated propel the balls against the inside wall of the jar, where they roll over the product. Grinding is effected primarily by way of impact and friction. The grinding and mixing time can be reliably set via a digital quartz timer for between 1 to 300 minutes. All settings are stored for use in subsequent cycles. To counter any agglomeration effects and enhance homogenization quality, the device is fitted with an automatic reversal system.The S 100 is powered by a high-performance, 100-watt brake motor which will bring the unit to a full stop in less than 1 second after the prescribed time elapses or after the safety cover has been
opened.
