This DESTONER is a key wheat cleaning machine used in the milling process. It plays a vital role in grading after pre-cleaning—concentrating light impurities such as mustard seeds, grass seeds, and wheat husks, while effectively removing heavy contaminants like stones and mud balls. The FQSZ series is also suitable for second-stage cleaning when wheat contains a high level of impurities—ensuring thorough separation and improved grain quality.
