Coarse aggregate accelerated polishing stone tester

The aggregate polishing value is obtained by using an accelerated polishing machine to polish the aggregate, and measuring the friction coefficient value of the aggregate after polishing with a pendulum friction coefficient tester, expressed in PSV.

This instrument is suitable for measuring the polishing value of various stone materials. The polishing value of stone is an important decisive indicator related to whether a stone can be used for anti-skid wear resistance of asphalt pavement.

The machine consists of a transmission mechanism, road wheel device, water supply system, load adjustment mechanism, counterweight device, trial mold, electronic control device, etc.
