Product Description:
· The SK screw element finds frequent application in the blanking section or side feeding section, where it enhances storage capacity to alleviate pressure buildup in these areas. Typically featuring a large lead, this element incorporates milled arc curves on the screw thrust surface, akin to those on a single screw. This design optimizes free volume within the twin-screw feeding section, facilitating effective feeding of powders and granules, particularly those with lower bulk densities. In the side feeding section or natural exhaust section, the SK screw element aids in re-relaxation of compressed materials, mitigating localized reversion tendencies.;
