Testing Process of the Particle Abrasion Tester
Measurement Principle of the Particle Abrasion Tester
The core function of the Particle Abrasion Tester is to accurately replicate the stress conditions that particles experience in real-world applications, ensuring that laboratory data closely corresponds to actual production performance.
The instrument applies controlled frictional and impact forces to particles through specific mechanical structures. Common working principles include rotary friction, airflow impact, and vibrational friction, each corresponding to different industrial particle characteristics.
Rotary friction type: The rotating drum drives particles to rub and collide with each other, simulating wear conditions in pipelines and silos during material flow.
Airflow impact type: High-speed airflow carries particles to impact a target plate, replicating wear in pneumatic conveying processes.
Vibrational friction type: A vibration platform causes particles to rub against each other within a sieve, simulating conditions in vibration screening and material transfer.
During the simulation process, the instrument is equipped with high-precision weighing modules and particle size analysis modules to monitor changes in mass and morphology in real time. The entire process is precisely controlled by an intelligent system, regulating parameters such as friction intensity, time, and rotation speed, ensuring repeatability and comparability of each test. This allows the wear resistance of particles from different batches and processes to be objectively compared under a unified standard.
