TORUSMILL SK5

Multi-purpose laboratory dissolver
For mixing, dispersion, vacuum dispersion, homogenization, and fine grinding

TORUSMILL® SK5 is a high-performance immersion basket mill that delivers excellent grinding results in a very short time. It is available with motor power options ranging from 30 kW to 45 kW for processing low to medium-viscosity products. The clamping device of the TORUSMILL® SK5 basket mill is suitable for container sizes up to 750 liters. Efficient circulation of the millbase throughout the grinding basket is ensured by an integrated, patented pump wheel. This enables a high number of passes and achieves narrow particle size distribution. The dissolver disc mounted beneath the grinding basket ensures grinding with minimal dead volume inside the container.

The double-walled grinding basket is suitable for both cooling and heating systems. Heat generated during the grinding process is effectively dissipated by a spirally directed cooling medium.

  • Perfect circulation at the bottom of the mill thanks to the patented pump wheel and dissolver disc

  • Easy scale-up from the TORUSMILL® TML laboratory basket mill to the TORUSMILL® SK production basket mill

  • Use of various container sizes thanks to compatibility with different customer containers

TORUSMILL® SK5 features an integrated cover:

The fixed cover of the TORUSMILL® SK5 immersion basket mill allows the shaft height to be easily adjusted even during the fine grinding process. The cover rests securely on the container rim during operation and comes standard with a product feeding system. Various options such as LED lighting for the container lid, PT100 temperature sensor, Liquiphant level switch (also ATEX compliant), inspection windows, and a variety of filling funnels are available.

TORUSMILL® SK5 comes with the BK5 stand:

The elegant stand of the TORUSMILL® SK5 series includes an integrated electric height adjustment. This new, intelligent, and particularly robust design was developed with full functionality and cost-effectiveness in mind, reflecting the innovative spirit of TORUSMILL® technology.

Fine Grinding Process with the TORUSMILL® SK Basket Mill

The container holding the pre-mixed liquid component is placed under the TORUSMILL® SK and securely fixed. The grinding basket is then immersed into the liquid to be milled.

At this stage, the TORUSMILL® SK begins the main dispersion process for fine grinding. Once the desired fineness has been achieved, the dissolver blade and grinding system are raised above the product surface, and the product remaining in the grinding basket is centrifuged by briefly operating the dissolver blade and grinding system.

Subsequently, the grinding system is fully raised, and the container filled with the ground product is removed for the next processing steps. Cleaning of the grinding system is performed in a separate conical container to minimize the amount of cleaning liquid required.
