Overhead rail shot blasting machine 3

Overhead rail or called continuous feed hanger shot blasting machines are particularly suitable for big production amount and big size work-pieces. Work-pieces are put directly on hangers or on tree hanger tools, rotation function optional.

The overhead conveying system can be designed as close loop or open loop which allows the machine integrated into a automatic production line.

Overhead rail shot blasting machines can process work-pieces like:

  • Casting workpiece
  • forging workpiece
  • weldment workpiece
  • machinery parts
  • cylinders
  • and other batched workpiece

Key feature of overhead rail shot blasting machine

Blast turbine

blast wheel☆Dynamic Simulation Design
The liners form a round track for abrasive, which allows all abrasive leave the turbine when they reach the highest speed with the least internal bounce and self-wear. Can offer high blast speed and full abrasive cover.
The maximum thickness of blast wheel shell can reach 70mm, better sealing effect, long service time.
The interior of the blasting wheel is turbo type, abrasive will not not stay in the distributor. Abrasive utilization rate increased to 99%, improve efficiency by 30%.
Blast wheel bottom has cushioning rubber, which can reduce vibration.
☆Blade & Impeller
The material of impeller is 40CrMnMo, the material of blade is high chorme wear-resistant casting iron, the hradness can reach HRC60-65.

Transportation system

☆Various Transport SystemOverhead rail transport system
Work-pieces are transported by close or open loop rail through a rubber belt sealed opening or automatic pheumatic doors
☆Flexible Process Speed
Step-by-step feed type and continuous feed type are chosen depending on abrasive time and work-piece, equipment size. With variable frequency speed control system.
☆Loading weight
According to different workpiece, the loading weight of each hoist can reach 50-2000kg

Blasting Chamber

☆ Working principlechamber of overhead rail shot blasting machine
The engineering team uses 3-D dynamic simulation design blast turbines layout to ensure that the steel shot ray can cover the surface of the workpiece 360 degrees.
☆10 Years Warranty
Shot blasting chamber with Mn13 steel guard plate which has high impact toughness and high service life, fully realize the reflection funcation of abrasive and improve the cleaning quality.
That we promise 10 years maintenance-free warranty to blasting chamber.
☆High sealing performance
3+ layers of sealing curtain in inlet, outlet opening and between chambers. The curtain layers are natural rubber material with leaf spring which can automaticlly reset,
that prevent the abrasive spatter out duing the blasting and ensure the safe.

Dust collectordust collector 232

☆Level-1 Dust Collecting: a gravity settling box above inlet/outlet chamber will make the abrasive shot in airflow drop back to chamber, so the dust collecting filter will not be damaged by abrasive shot, can a chieve a longer service time.
☆Level-2 Dust Collecting: Cyclone dust collector have 2 collection poits for dust and debris, primary collection point is for heavier chips and debris, while the second point is for finer particulate matter. Cyclone dust collector use a centrifual force for separation. Then airflow transition into downward spiral and forces the bigger contaminants into first collecting point, then the smaller contaminants into the second point.
☆Level-3 Dust Collecting: high filtering areage cartridge type or venturi design bag type filter can offer a long service time high filterability effect, the final cleaning efficiency is upto 99%.
