Heavy-duty screw press
SPIROPAC Dewaterer & Compactor
The SPIROPAC® is a heavy-duty shaftless screw press which compacts coarse materials of consistent or mixed sizes. The SC model achieves exceptionally high compaction ratios by combining an extremely strong spiral, low speeds and very high torques to exert high pressure on the material to be compacted.
A plug is formed against dual-back pressure plates which can be adjusted according to compaction requirements. The SPIRAC SC-D Compactor has an optional dewatering zone which can be incorporated for wet materials.
