Centrifugal Cleaning Flashcards
Some general basic centrifugal blast setups include?
Tumbling Mill Multi-table Plain table Swing Table Custom designed systems
Centrifugal blasting conveyor systems are commonly used for cleaning of?
Plate
Rolled structural shapes
Large trusses
Girders
Portable centrifugal blasting systems can be used on?
Ship decks, hull sides and bottoms
Storage tanks
Concrete floors
Generally centrifugal blast systems are composed of what elements?
Centrifugal abrasive throwing wheel Blast cabinet (or enclosure) (in fixed systems) some type of material handling system Abrasive recycling system A dust collector and vent pipe system Abrasives
Efficiency of the centrifugal blast wheel(s) depends on several factors
Abrasive operating mix
Size of the abrasive
Velocity of the abrasive coming off the wheel
Quantity and direction of thrown abrasive
Condition of the feed parts
Low amperage reading on a centrifugal blasting machine could signify?
An abrasive-starved wheel
A flooded or choked wheel
The functions of the centrifugal blasting machine separator include?
To control sizing of the abrasive mix
To remove sand, spent abrasives (fines), rust, dirt and any other contaminants from the abrasive stream
To control abrasive consumption
A well balanced operating (working) mix of abrasive sizes will?
Provide consistency of the finish
Ensure uniform abrasive coverage
Ensure conditioning of the abrasive for optimum cleaning
Minimise lowest abrasive and machine part-wear and reduce downtime for maintenance
Some of the inspection concerns during centrifugal blasting include?
Monitoring the dust collector
Monitoring the amperage of the wheel motors (for low amperage)
Monitoring the handling and loading of the conveyor line for contaminates/possible discontinuities in the steel
Monitoring the speed of the line
Inspecting the steel as it leaves the production line
