Introduction.
The AP1000R Robotic System is designed to process up to 800 samples per day with an input sample weight varying from 800g to 10kg and a maximum particle size of 60mm. The final product required was a 300g sample (particle size of 95% -75microns) plus a 300g retained sample with the balance to waste.
ROCKLABS universally accepted products including the Boyd Crusher, LSD (Linear Sample Divider) and Automated Batch Mill with automated cleaning cycle are utilised in this System. An ABB Robot is used to load and retrieve the sample bins from the various positions within the System.
System for Blast Hole and R.C. samples•
Sample placed on scale and weighed, bar coded and data entered.
•
Sample travels on roller conveyor to robot pick up point.
•
Robot retrieves bin & loads into Boyd Crusher for crushing.
•
LSD located beneath Boyd Crusher divides sample into 3 way split: 1 x 300g sample & 1 x 300g retained sample (which are loaded into two smaller bins. The balance is captured in the retained waste drawer or bypassed to waste conveyor for easy removal.
•
Robot retrieves the 2x 300g bins from under Boyd Crusher & places in a station beneath Batch Mill. Robot then lifts and empties 1 x 300g sample bin into Batch Mill for pulverising and places empty bin next to retained sample bin.
•
Processed sample from Batch Mill loaded into empty sample bin.
•
Robot lifts the 2 x bins containing 300g sample and Retained sample and places onto return conveyor.
•
This process is repeated.
•
The crushing time in the Boyd Crusher will vary depending on the sample weight. The Robot is programmed to take into account the varying crushing times in the Boyd which will thus determine the loading sequence of the Batch Mills.
