Product Description

STJM-3 Accelerated Polishing Machine (PSV)
Aggregate Accelerated Rock Polishing Machine

Application: The grinder is used to polish stone materials, evaluates their resistance to polish,  and provides friction coefficient information in road pavement. This instrument is suitable for indoor simulation of the polishing effect of automobile tyres on highway pavement. By accelerating the polishing of aggregates used in pavement, the polishing value of aggregates can be measured to evaluate the anti-polishing performance of aggregates, so as to provide scientific basis for selecting suitable aggregates for paving sections with different frictional coefficients and for rational development and utilization of stone resources, so as to shorten the anti-skid pavement. The research period creates conditions for the development of artificial aggregate.
