InlineStar High-performance Fine Classifier

The true Inline Classifier

The combination of a fine grinding mill with a downstream air classifier is unavoidable for many product applications. The newly developed InlineStar however, can distinctly reduce the necessary expense!

An In-Line classifier combined with a fine grinding mill enables one to reduce the number plant components and energy! The intermediate separation of the product after the grinding stage is no longer required eliminating the need for cyclone, filter and exhaust blower.

The classification results are impressive. The sharpest separation, highest fineness and maximum possible yield is achieved!

The new InlineStar is available for testing in our laboratory in Hanau.
