Description
DISPERMAT® RS-EX: New generation of horizontal bead mills for fast and excellent grinding results in the passage and circulation process
For many years VMA-Getzmann has been a specialist in dispersion and milling technology with the DISPERMAT® and TORUSMILL® dissolver, bead mills and basket mills. The new horizontal bead mill series with a chamber volume from 5 to 30 litres is made for universal use.Today`s demanding application require also ultrafine particle size. Therefore it is suitable for grinding bead diameters from 0.3 mm up to 2.5 mm. With this flexibility the horizontal bead mill DISPERMAT® RS-EX can operate a wide range of products and viscosities.
The agitator ball mill can be taken apart in just a few steps allowing a rapid product change. The optional cooling of the rotor allows the grinding of temperature-sensitive products. To prevent metal wearing of parts during the milling process, the horizontal bead mill DISPERMAT® RS-EX can be equipped with ceramic or plastic lining. The wearing of those materials are not changing the color or transparency of the product. The shaft seal is a single mechanical seal developed by VMA-GETZMANN. The compact design of the seal cartridge enables a quick and easy cleaning or replacement. The sealing liquid is integrated in the machine housing.

PLC technology
The DISPERMAT® and TORUSMILL® dissolvers, bead mills and basket mills can also be fitted with the PLC-control. The graphic display allows for an indication of the operational parameters such as speed, power output, peripheral speed of the milling tool, torque and product temperature. The combination of a graphic display and the standardized PLC-control allows for an extension as well as for an adaptation of the control system to further process control applications at any time.
