Perforated mild steel huller screen/husker screen and polisher screen:
The metal screens are mainly used as spare parts for hulling rice and separating rice hulls and shriveled rice from rice and paddy mixture. Also used for millet polisher, coffee pearling, maize husker, and other grains’ huller. By means of roller’s rotating in the machine, grains are milled each other among the screens. Reaching the required grade, polished grain flows out from the outlet. At the same moment, the grain’s husk flows out from the holes in the screen.

Benefits of Using Perforated Huller /Husker/Polishing Screens:
Most cost-effective prices;
High-quality mild and stainless steel offering good ability in abrasion resistance;
Advanced heat-treatment technology and thick screen stands more wear and tear;
Specialized design and manufacture different screen for round-shape grain and long-shape grain, various processing;
Complete varieties: Different screen filters for rice grain, big grain such as coffee, and little grain such as millet;
OME order acceptable.


Screen Length normal size: 223mm, lengthened size: 308mm
screen thickness normal size: 1.2mm; thickened size; 1.8mm; thinned size: 1.0mm
Punched or Slotted holes’ size length: 10-15mm, width: 0.8-1.5mm
Surface finishes Normal oiled surface; electroplated surface; stainless steel plain. Electroplating steel screen owns better corrosion resistance than oiled steel. SS offers better property than electrogalvanized.
