Bottom sieve trapezoidal perforation made of stainless steel.
The bottom sieves are made of stainless steel trapezoidal resp. round perforation sheets metal. Larger openings mean faster throughput, less time in the mill and less wear.
Bottom sieves with trapezoidal perforation offer an improved size reduction through extra shearing action. Bottom sieves with round perforation are recommended for size reduction of brittle material of medium fineness with smaller grain width band.
