A customer in the copper mining and exploration industry contracted DeMarco Industrial Vacuum Corp. to engineer and manufacture a custom industrial vacuum for a critical application. Consulting closely with the customer, our engineers provided feasibility studies to evaluate the application environment and determine vacuum design criteria. The vacuum was to process mining debris resulting from mezzanine deconstruction operations. The mineshaft measurements were 30' in diameter with 6200' maximum depth at the base of the shaft. Mezzanine deconstruction was being performed from 500' deep to the base.
The vacuum system included a DEMARCO® MAXceptor® pre-separator hopper that would be lowered into the shaft for filling, and then lifted to the surface for emptying, along with a drive package located in the elevator. A quick disconnect between the vacuum's drive package and the hopper was also provided. Operational features for this stationary unit includes a 480 volts/3 phase/60 hertz power supply and compressed air available at 120 psi, 45' vacuuming distance, and 25' vertical range. The unit is equipped to handle slag particles up to 2.5" in size, with less than 50% moisture content.
The nozzle set measured 3" I.D., and the 25' sectioned hosing was 3" I.D. as well. The enclosure met NEMA 4 standards for waterproof and dust construction, as well as our high standards for uncompromising quality and integrity. The vacuum was subjected to comprehensive pre- and post-production testing to verify overall integrity. This vacuum system was designed and manufactured within an 8 week turnaround time, shipped to the customer on the west coast.
