HP-MS: Automatic vibratory disc mill

Short grinding time – long service life

The HP-MS is suitable for grinding a wide variety of minerals such as cement raw meal, clinker, cement, slag, ores, oxides and ferro-alloys. The high RPM of the drive motor guarantees a short grinding time even for hard materials. The robust construction with, e.g., dual bearing support for the eccentric shaft ensures long service lives.

High precision and flexibility in pulverizing

The operator has full control over the pulverizing process and can adjust all relevant machine parameters and process steps. The rotation speed of the grinding vessel is continuously adjustable between 600 and 1500 rpm. The temperature is constantly monitored and kept constant at target temperature. The sample feeding and discharge intervals, the timing for adding grinding aid, the cleaning cycle and much more can be adapted to achieve the optimum result for each material.

The grinding vessel has a volume of 100 ccm which offers maximum flexibility for operation of all kinds of material. Both chrome steel and tungsten carbide grinding vessels are available and can be exchanged with little effort.

Effective avoidance of cross contamination

After pulverizing the grinding vessel is automatically emptied and the ground material is made available at the discharge point. Three automatic cleaning features namely compressed air, sand cleaning (option) and wet cleaning (option) allow a sufficient material removal. Using the different cleaning functions, cross contamination can be reduced to a low ppm level. Furthermore, spoon sampling (option) during the material input provides the possibility to pre-contaminate the grinding with the subsequent sample. 

Various options, flexible configuration

The HP-MS can be equipped with a dosing system for solid or liquid grinding aids to improve grinding efficiency. Furthermore, cooling of the grinding vessel is available to allow pulverizing under controlled temperature conditions. The HP-MS has been designed for operation within a robotic automation. It can also be used as a stand-alone machine with input for a single sample or with 30 or 60 position magazines.

Tool Condition Monitoring

The HP-MS is ready for smart industry solutions enabling tool condition monitoring and predictive maintenance. Integrated sensory technology allows the online monitoring of the grinding performance as well as wear of swing aggregate and grinding set. This powerful tool, in combination with the PrepMaster Analytics software, makes it possible to assure reproducible sample preparation conditions for more accurate analysis. In addition, the HP-MS allows the fully automatic determination of the specific grinding energy of a material. This enables QC laboratories to easily and immediately determine the grindability - a procedure that is otherwise reserved for highly specialized laboratories.
