Blasting takes place at two of the six spindles, which are positively driven by a toothed belt to ensure an even blast coverage during the rotation of the component. Components can be either manually, pick and place or robotically loaded and unloaded depending on volumes, handling complexity and subsequent operations.

A suction or pressure fed media delivery system, media separator and dust extraction system make up a complete installation and these items are specified to match each specific application.

A typical Multiblast RXS1400 system may include:

• 6 x Model 900 Blast Guns complete with electrical solenoid switches allowing individual blast guns to be selected to suit the application.
• Blast guns mounted on adjustable mounting blocks so that the angle of blast and stand-off distance can be adjusted to give optimum coverage of the component.
• Blast guns secured to a vertical traversing gun drive - for taller components
• Pneumatic doors cover the component entry and exit ports, doors synchronised to the blast cycle to minimise dust escape
• Reverse Jet Pulse Cleaning Dust Collection Unit may be fitted with a secondary HEPA14 filter, back-flap, and Hoerbiger explosion relief valve or fire suppression device (depending on application)
• HMI/PLC control systems with graphic interface

Prospective users of Guyson automated blast finishing systems are encouraged to submit sample components for free feasibility testing in the company’s extensive Component Finishing Centre at Skipton, England.
