Continious process of material treatment occurs in closed channel between two walls oscillating in anti-phase regime and moving along elliptical trajectories. The process is being implemented by periodical compression and loosening of granular material, which is being vibrotransporting along the channel.
The control of abrasive and compressive impact on material carrying out by сhoose of longitudinal and transverse stiffnesses of elastic elements, changing of vibration parameters and density of filling the working camera by material (patent RU 2675554).
Perspective applications of proposed method of attrition and mechanical activation of grained materials surface can be found in construction, mining, chemical, foundry and other industries.
