High-Quality Coarse aggregate accelerated polishing stone tester Manufacturers, Quotes

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.

Frequently Asked Questions
Q1: What does PSV stand for in stone testing?
A: PSV stands for Polished Stone Value, which measures the resistance of aggregate to the polishing action of vehicle tires.
Q2: What is the significance of the 406mm road wheel size?
A: The 406mm external diameter is a standard technical requirement to ensure consistent speed and friction application during the polishing process.
Q3: Does the machine support different voltage inputs?
A: Yes, the system is designed to work with 380V, 220V, and 24V (± 2V) power supplies.
Q4: How many molds are provided with the machine?
A: The machine includes 8 sets of dedicated polished stone molds for comprehensive testing.
Q5: Is this machine compatible with all types of stone?
A: Yes, it is suitable for determination of the polishing value of all types of stone aggregate used in road construction.
Q6: Why is determining the PSV important for asphalt pavements?
A: It is a decisive indicator of whether a stone can provide sufficient anti-sliding properties for safety in the asphalt pavement surface layer.
