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.

Application

(1) Determining wear rate of fertilizer catalysts, molecular sieves, and adsorbents

(2) Evaluating the mechanical durability of industrial activated alumina

(3) Testing strength and abrasion resistance of wood activated carbon

(4) Quality control in chemical and pharmaceutical production

(5) Research and development for new granular materials with improved durability

(6) Comparative testing of particle materials to optimize process efficiency

Standards

(1) GB 3636-83 — Method for determination of wear rate of catalysts, molecular sieves, adsorbents

(2) GB 10504-2008 — 3A Molecular Sieve

(3) HG/2524-2011 — 4A Molecular Sieve

(4) GB 13550-92 — 5A Molecular Sieve

(5) GB/T 12496.22-90 — Test method for strength determination of wood activated carbon

(6) HG/T 3927-2007 — Industrial activated alumina wear testing

(7) ISO 3270 — Determination of particle size distribution and durability of granular materials (international standard reference)

(8) ASTM D4179 — Standard test method for wear of granular catalysts

Features

(1) Stepper motor with single-chip microcomputer control for precise, stable, and uniform grinding speed

(2) Low noise operation for improved laboratory comfort

(3) LED indicators display real-time working status clearly and intuitively

(4) Adjustable speed settings (25–100 r/min) to accommodate different material types and test requirements

(5) Functions include preset speed, alarm settings, and automatic pause for enhanced safety and control

(6) Dual grinding cylinder sizes (Φ36×300 mm and Φ50×300 mm) for versatility

(7) High stability and low failure rate, ensuring long-term reliable operation

(8) Simple and intuitive operation, suitable for routine laboratory and industrial testing
