Tunnel type shot blasting machine is a overhead rail machine with open loop, 1 inlet opening and 1 outlet opening. It is suitable for middle, big sized work-pieces hung directly on hangers or small work-pieces hung to customized jigs.
Multiple blast turbines are installed in the working chamber for full abrasive coverage. Extra cleaning units like high pressure blower is available for better surface cleanness.
Tunnel type shot blasting machines are often integrated into a automatic production line before painting process.
Tunnel type shot blasting machines can process work-pieces like:
Agricultural machinery parts,

Key feature of tunnel type shot blasting machine
☆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 chrome wear-resistant casting iron, the hardness can reach HRC60-65.
☆ Working principle
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 function 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 automatically reset, that prevent the abrasive spatter out during the blasting and ensure the safe.
Max 3-grade dust collecting design can achieve max 99% clean efficiency.
☆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.
☆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%.
