Roller Conveyor Passing Shot Blasting Machine for H Beam Structural Steel Cleaning Abrator

Product Description

     Application of Machine
     Roller Pass-through Type Shot Blasting Machine is to remove the rust,strengthen and spray anti-rust film for welded workpieces before its processing.
    Advantages after cleaning:

1. Improve its crrosion resistance of mechanical products & section steel.
2. Improve the fatigue performance of components,extending its life.
3. Optimize the component surface state.
4. To be favor for feeding of CNC cutting machine and precision output.
5. Because of the regular shap of workpieces before processing, it's helpful for dust-removing and paint spraying.
6. Improve cleaning efficiency greatly.
7. Reduce working intension.
8. Reduce the environmental pollution.

     Roller pass-through shot blasting machines are generally used for construction machinery, mining machinery, chemical equipment, pressure vessels, transport vehicles, ships bridge and building profiles, and other industries.It's used to improve the appearance of its quality and surface corrosion resistance.

Mainly Feature
1. Rolling Conveying System

• There is a detective roller on each side of inlet roller and output roller
• The full set of roller conveying system is able to work simultaneously, but aslo to work separately.

2. Shot Blasting Cabinet

• ZGMn 13 protection,building-block shield installation.
• Adopt computer simulation to determine the place of blast wheel.   

3. Abrasive recycling and purifying system

• Installed the fault alarming system for the abrasive recycling system
• Purifying rate is above 99%

4. Electric control system

• The whole line is controlled by programmable logical controller (PLC) from Siemens
• Distributed controlling desks are located at suitable positions
  As an option, the system can be equipped with the software of "Steel plate pretreatment line, dynamic simulating and monitoring system (controlling center)"
• Mostly electric components are from Siemens
