Particle Abrasion Tester

The Particle Abrasion Tester (Q-4D) is a precision instrument designed to measure the wear rate of granular materials such as catalysts, molecular sieves, adsorbents, activated alumina, and wood activated carbon. Based on national standards, it provides a controlled and repeatable method for evaluating particle durability under simulated industrial conditions. The Q-4D improves upon its predecessor (Q-3) with enhanced performance, optimized structure, and greater operational stability, making it suitable for chemical, pharmaceutical, petroleum, and material research laboratories.
