Automatic Falling Sand Abrasion Tester

The Fully Automatic Falling Sand Abrasion Tester is designed to evaluate the wear resistance of anodized aluminum surfaces and organic polymer coatings. The device continuously directs abrasives from a controlled height and stable flow onto the sample surface, using the wear per unit coating thickness as an objective measure of abrasion resistance. This tester is widely used in material wear testing, quality control, and surface treatment industries.

Testing Principle

During testing, standardized abrasives fall freely through the conduit under gravity from a specified height, continuously impacting the sample surface. As the test progresses, the coating gradually wears. By measuring the coating thickness or wear per unit area before and after the test, you can evaluate the coating’s abrasion resistance. This method effectively simulates particle-induced wear in real-life use.

Maintenance Information

(1) Clean the conduit regularly to avoid blockage

(2) Check abrasive flow consistency before testing

(3) Inspect hopper and fixtures for wear

(4) Replace abrasives according to usage conditions

(5) Keep the equipment in a clean and dry environment
