The wire mesh type shot blasting machine is a fine design for continuous blast cleaning to all-around surfaces of work-pieces with different shapes.
The work-pieces are transported by an endless wire mesh belt, which can resistant abrasive stream and allows cleaning to below surfaces of work-pieces. Work-pieces from small to long profiles are all available for wire mesh machines.
To lengthen the service time of wire mesh belt, an intelligent feeding system can stop abrasive feeding when no work-pieces in blasting chamber, the service time of belt and blasting chamber is lengthened by max 20%, energy cost by max 30%.
Wire Mesh Belt machines by QGMA are used for desanding of flat, thin walls and fragile parts of iron and aluminium alloys which have special demands on shot blasting machine as well as shot blasting process.
- Rust and heat scale removal
- Deburring of cast flanges
- Sand removal from oil sumps
- Improvement of surface roughness
- Shot peening for fatigue improvement.
Key feature of wire mesh shot blasting machine
☆Dynamic Simulation Designblast wheel
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.
☆ 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 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.
Wire mesh transport system
☆Wire mesh belt is available for parts with wide range of weight and size, including small sized parts not suitable for traditional roller conveyor type machines. Work-pieces can be blasted from all directions.
☆The Mesh Belt shot blast machines provide a frequency controlled speed variable mesh belt surface on which a variety of parts can be uniformly blasted. The high-quality mesh belt ensures that the workpiece remains in the perfect position to be blasted. As each part is blasted in a controlled fashion this technology is perfect for thin-walled parts.
☆The mesh belt is of high wear resistance, it can use 8-9 years.
