Accelerated Polishing Machine

Accelerated Polishing Machine

The accelerated polishing machine (PSV) is used to simulate the car wheel abrasion to the pavement surface, by accelerated grinding on the aggregate thus to get the aggregate polishing value, and estimate the aggregate abrasion resistance, thus to select suitable aggregate for different road construction requirements, it’s designed and made by complies to the standard, and also absorb the foreign made advantages. It features compact structure, intelligent control.

The accelerated polishing machine (PSV) polishes the coarse aggregates then use pendulum skid resistance tester to test the friction coefficient, that’s called as the PSV. The machine comprised of transmission mechanism, road wheel, rubber wheel, abrasion material feeding system, water supply system, weights, molds, loading adjusting device, control panel. The road wheel is used to install 14pcs specimen,

Power supply: AC 380V 50Hz,
Road wheel rotation speed: 320±5RPM
Rubber wheel to the specimen total pressure: 725±10N
Rubber wheel size: Φ200×44mm, hardness:
The “C” rubber wheel is used for grind the coarse sand, the X rubber wheel is used for grind the fine sand.
Diamond sand (30# brown fused alumina,280#green silicon carbide
