The Accelerated Polishing Machine is designed to determine the Polished Stone Value (PSV) of road aggregates, paving stones, and concrete blocks, replicating the abrasive action of vehicle tyres on a road surface.

This testing system allows up to 14 specimens to be polished simultaneously on a rotating road wheel that interacts with a solid rubber tyre under spring load. The machine features dual mechanical feeders for continuous abrasive supply (corn and flour emery), placed on a detached support frame to reduce vibration effects and preserve calibration integrity.

The unit includes a digital control panel displaying wheel rotation speed and test countdown. A built-in water container with a flow regulator ensures a controlled supply during polishing. The polished specimens obtained are perfectly compatible with Skid Resistance Testers for further frictional analysis.

Supplied with:

• 2 rubber wheels (for corn and flour emery)
• 4 specimen moulds
• 2 mould covers

Abrasive materials and control stones must be ordered separately (see accessories).
