The CPA 4 Graviopt combines the advantages of photo-optical size analysis and gravimetrical measurement. The material to be analysed is conveyed by a Haver EMZ vibratory feeder and classified by a Haver DMS purpose built screening machine whereby the cut point is freely selectable. The sieve overflow is analysed photo-optically and discharged to a rotating hopper scale for the gravimetrical measurement. The mass fraction of the sieve underflow will be determined directly by a second rotating hopper scale.

The CPA software evaluates and combines the total distribution of the sample with the information from the photo-optical and gravimetrical measurements, the result is a complete sieve curve from very fine to the coursest material. The CPA 4 Graviopt measures materials up to 50mm grain size.
