Polystyrene compactor EPS

stationaryscrew

Overview
PRESTO's SPN system compacts large volumes of styrofoam (EPS) by combining a pre-crushing stage with an auger compactor. The solution is designed for processing bulky EPS waste streams and optimizing material feed into the compaction unit.

Operation
The feed system uses an MZ 3 or PZZ cardboard feeding crusher to pre-crush and homogenize the material before it enters a special pre-compaction channel. This prevents re-expansion and ensures the material is pressed continuously into the coupled PRESTO container.

Performance
When processing styrofoam (EPS) the system reaches a compaction ratio of approximately 1:25 to 1:30 and achieves a container content weight from at least 3.5 tons (SPB 30), reducing volume significantly for transport.

Benefits
The high compaction ratio lowers transportation costs and reduces the number of truck runs compared to transporting loose EPS in open containers, improving logistics efficiency and storage space utilization.
