KEY FEATURE of STEEL STRUCTURE SHOT BLASTING MACHINE

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.

Roller Conveyor System

☆ Infinitely variable speeds
The conveying system of the whole production line adopts stepless variable speed adjustment, and the conveying system is composed of the input roller conveyor, blasting chamber roller conveyor and the output roller conveyor.
☆ Proper alignment
High quality carbon seamless steel pipe is adopted for the roller shaft of the input and output roller conveyor, and roller is first welding and then processing, to ensure the concentricity of the roller. Usually it can use 8-10 years.
☆ Wear resistant sheath
The roller conveyor in blasting chamber has high chromium molybdenum wear resistant cast iron shealth, that can protect the roller conveyor avoid abrasive.

Photoelectric sensor system

☆ 2 sets photoelectric sensor system are located at the inlet and outlet the chamber, grating density can be selected according to the size of the workpiece, used in pairs.
☆ The workpeice reach inlet of chamber, the photoelectric sensor system will send signal to computer then the machine will start to do the blasting work, and it will automatic stop after the workpiece out of the blasting zone. That will avoid the blast turbines work when the blasting chamber without workpiece, extend the service time of blasting chamber, and let energy cost saved max 30%.

Dust collector

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 achieve a longer service time.
☆Level-2 Dust Collecting: Cyclone dust collector have 2 collection points 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 avreage cartridge type or venturi design bag type filter can offer a long service time high filter ability effect, the final cleaning efficiency is upto 99%.
