CN223644018U - Masterbatch sieve separator - Google Patents

Abstract

This utility model discloses a masterbatch screening machine. This utility model uses multiple filter plates with different filter hole diameters set on a screw conveyor to perform initial screening of a pair of masterbatches. Then, a screening box is set below the filter plates, and a second filter plate is set in the screening box to perform secondary screening of the masterbatches. A recycling channel is also set at the lower end of the screening box to send smaller masterbatches mixed in to the previous screening box for re-screening. This setting can avoid smaller masterbatches from being mixed with larger particles, making the screening more accurate.
