Description
Explosion-proof TORUSMILL® SK6-EX basket mill: excellent fine milling results in a very short time!
The TORUSMILL® SK6-EX are high‒efficient immersion mills with which excellent grinding results can be achieved in very short time. The TORUSMILL® SK6-EX basket mill is available from 45 kW up to 55 kW motor power for processing low and medium viscosity products. The clamping device of the TORUSMILL® SK6-EX immersion mill is suitable for container sizes up to 2500 liters. The effective circulation of the mill base through the grinding basket is achieved through an integrated, patented pump wheel. This provides a high number of passes, and a narrow particle size. The dissolver disc mounted below the milling basket ensures a milling of the millbase within the milling container with minimal dead volumes.
- Double walled milling basket, suitable for cooling and heating systems. The heat generated during the milling process is dissipated effectively by the spirally guided cooling liquid
- Excellent circulation of the mill base by 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 customers existing containers, also with different volumes
According to the Directive 2014/34/EU (ATEX 100a), the explosion-proof immersion mill corresponds to the following ATEX protection class: II 2G Ex h IIB T3 Gb.
The explosion-proof TORUSMILL® SK6-EX production basket mill has an integrated cover:
The stable cover of the TORUSMILL® SK6-EX immersion mill enables easy height adjustment of the shaft even during the fine grinding process. The cover rests securely on the container edge during the grinding process. The cover is equipped with a product feed system as a standard. Various options, such as LED lighting, a PT100 temperature sensor, a Liquiphant level switch (also in ATEX), or sight glasses and various filling funnels are available for the container cover.
The explosion-proof TORUSMILL® SK6-EX production immersion mill is equipped with the T6 hydraulic stand:
The T6 stand of the TORUSMILL® SK6-EX basket mill is a tried and tested hydraulic stand for product quantities of up to 2,000 liters. The height is adjusted hydraulically via a system on the stand base.
The applications of our high quality TORUSMILL® SK6-EX immersion mills are versatile:
- Paints and varnishes
- Pigments and additives
- Printing inks
- Chemistry
- Plastics
- Construction chemistry
- Electronics
- Adhesives
- Coatings
