0363 Prevention of wall accumulation in wood chip dust collector hopper

0363 Prevention of wall accumulation in wood chip dust collector hopper

Easy resolution of sawdust accumulation on hopper walls! Introducing a case study of Brody Disk delivery!

This is an introduction to a case study implemented as a countermeasure for the issue where "wood powder" accumulates on the walls of the dust collector hopper and occasionally falls in clumps, causing the discharge rotary valve to stop. A total of 12 standard blow disks, three on each side, were installed. By using a controller with six solenoid valves, the blow disks are divided into six locations and sequentially air-jet two at a time, effectively resolving this issue. This product ejects air in a 360° direction along the inner wall of the hopper from the periphery of the elastic disks set on the inner surface of the hopper, thereby easily eliminating the accumulation of wood powder on the hopper walls in this case. [Overview] ■ Dust collector hopper dimensions: 2000×2000 ■ Discharge section: 150□ *For more details, please refer to the PDF document or feel free to contact us. *Our website features numerous case studies.
