Product volumes are based on medium viscosity. The actual volume may differ depending on the flow behaviour of the product. All instruments can be supplied with different working voltages.

Closed horizontal bead mill for repeatable dispersions with very high mill base yield

DISPERMAT® SL laboratory and pilot plant mills are closed, horizontal bead mills with high output and extremely low dead volumes in the mill base inlet and outlet pipes. During the dispersion process, the product is fed through the horizontal milling chamber and continuously dispersed. The DISPERMAT® SL bead mill can be used for the pass as well as for the re-circulation process. After dispersion, the integrated air pressure system presses the remaining mill base out of the milling chamber which allows an complete recovery of the dispersed material.

Due to minimised dead volumes even the smallest quantities can be dispersed with high yield. Thus, the DISPERMAT® SL is an ideal tool for research., development and quality control. Also, larger quantities can be processed within a very short period of time. In order to minimise the product loss, the mill base is transported directly from the supply vessel into the milling chamber. The dispersed product passes through the mill base separation (dynamic gap) and is recovered either in a vessel (pass method) or flows back into the supply vessel (re-circulation method).

• Quick and cost-effective of new formulations due to exact repeatability of dispersions.
• Quick and reliable transfer of laboratory development into production because of quantitative knowledge of the required mechanical power input.
• Quality control and assurance of production.
• Efficient control of incoming raw materials by measuring product properties relevant for the application.

Diagrammatic view of the bead mill DISPERMAT® SL:

pumping and stirring system* supply vessel milling system product * the bead mill DISPERMAT SL with M-control is fitted with a pumping and stirring system as an optional accessory. The milling system is made of wear resisting, high-alloy special steel. As an option it is also available made of: Zirconium oxide - No metallic abrasion - No colour deviation Silicium carbide - Very good caloric conductibility - No metallic abrasion Hard metal - Good caloric conductibility - Suitable for high abrasive media

The bead mill DISPERMAT® SL is supplied with VITON (FKM – rubber) O-rings as standard. Alternatively EPDM (ethylene propylene) O-rings can be fitted at no extra charge. If VITON or EPDM is not compatible with the products being milled, O-rings made from one of the following perfluoroelastomeres are recommended: KALREZ®, CHEMRAZ®, PERLAST®. A detailed resistance list can be found in our range of accessories. Forward to the resistance list »

The milling system of the horizontal bead mill DISPERMAT® SL:

• Milling system (stainless steel milling chamber, nitride steel milling rotor) Option: hard metal, ceramic (ZrO2), silicium carbide (SiSiC)
• Millbase separation by dynamic gap
• Shaft seal by means of mechanical seal, built into easy to install cartridge system integrated, pressurised and cooled lubrication liquid
• Minimised dead volume
• Dispersion of small quantities of millbase is possible due to almost complete product recovery
• Very high millbase yield
• Excellent temperature transfer due to veined cooling water system with extremely large surface area
• Cooling water connections: two self-sealing fittings and two quick couplers
• Milling beads of glass, zirconia etc.

Quick change of material and easy cleaning:

• Easy to use and secure to handle
• Easy cleaning, allowing quick change of material

The multi-purpose bead mill DISPERMAT® SL:

• One-pass-procedure and continuous pass procedure
• Circulation procedure with integrated pumping- and stirring system
• Dispersion of flowing and non-flowing products
• High mechanical power input permits processing of difficult to disperse products.
