Fritsch® bottom sieve 6 mm round perforation stainless steel

The bottom sieves are made of stainless trapezoidal or round perforated plate. The larger the perforation is chosen, the higher the throughput and the lower the retention time and wear. Bottom sieves with round perforation are recommended for crushing brittle materials and materials of medium fineness with narrow grain width band. Bottom sieves with trapezoidal perforations provide additional size reduction through increased shearing action.
