POLYGON MACHINE

Mechanical Stabilization Plant (Pug Mill)

Polygonmachine MSP Series – Mechanical Stabilization Plant (Pug Mill)

Polygonmachine MSP Series Mechanical Stabilization Plants (Pug Mills) are engineered for high-capacity, continuous, and uniform mixing of aggregates, cement, water, and additives for producing high-quality road stabilization material (PMT), sub-base, cold-mix asphalt, backfilling blends, and Roller Compacted Concrete (RCC).
With robust mixing shafts, high wear-resistant paddles, and fully automated dosing controls, the MSP Series delivers consistent output even under the most demanding construction environments.
