PART FIXTURING Canablast will provide eight disc support fixtures of two different sizes.
F.
PRESSURE VESSEL 1. One (1) single chamber, A.S.M.E. code approved pressure vessel will be provided. This vessel will be
equipped with Canablast “Sure-Flo” adjustable pinch tube media regulators which will start and stop the flow of media into the air stream. The pressure vessel will refill each time a cycle is complete. The nozzles will be mounted in a nozzle holding fixture. Once locked into place, the nozzles will not change position due to vibration, inertial loads, or other forces normal to the system.
2. Pressure Vessel Details : a. Construction : b. c. d. e. f.
A.S.M.E. code approved, single chamber, continuously welded, cylindrical steel tank Tested Working Pressure : 125 psig Capacity : 10 cubic feet Quantity of Outlets : Six (6) Nozzles : Six (6), 1/4” diameter, Boron Carbide, Straight Type This assembly includes (2) level probes for automatic vessel refill. If the pressure vessel reaches a low level condition during the blast process, the cycle will go into a ‘hold’ while the vessel depressurizes and refills. The cycle will resume upon completion of this refill cycle.
g. A “Low Media Level Light” and sensor will be installed on the system. When the level of media in the Automatic
Media Replenishing Hopper reaches a low level, the light will signal the operator to refill the system. (signal only)
3. Piping String : a. 2” NPT Inlet - Ball Valve b. 2” General Purpose Filter - 40 Micron Element with Automatic Drain and Sight Glass (Norgren)
2” Precision Regulator with Pneumatic Feedback - Relieving Slave Regulator, ¼” Pilot Regulator (Norgren) with Electronic Pressure Controller c. 2” Control Valve - Aquamatic, Normally Open, Spring Assist Closed d.

MEDIA SEPARATION SYSTEM 1. Spent media will be pneumatically conveyed to a cyclonic reclaimer where reusable media will be recovered and deposited in the storage hopper. Dust and unwanted, broken-down media will be conveyed to the dust collector. The cutoff point between good and bad media is adjusted by means of a tuning band which encircles the reclaimer. The positioning of this band determines the amount of secondary air entering the system. Oversize debris will be captured by a removable scalping screen in the storage hopper.
2. Reclaimer Details : a. b. c. d.
Construction : #12 gauge steel continuously welded. Access Door : Hinged and gasketed. Capacity : 1,600 cfm. Wear Plate : 1/4” thick neoprene pad positioned 120 degrees around the reclaimer and secured by a steel plate. e. Interior Liner : The reclaimer interior will be lined with Ultrawear pure gum rubber. This material is extremely resistant to abrasion and will increase reclaimer life.
3. Media Conveying Duct : Schedule 80 rigid urethane duct will direct the media from the collection hopper of the blast enclosure to the reclaimer. This ducting is recommended when the blast process is continuous or an aggressive abrasive such as aluminum oxide is used.
4. Dust Hose : (15’) of neoprene coated, two-ply cotton flexible duct will be supplied to convey dust from the reclaimer outlet to the dust collector inlet.
H.
AUTOMATIC MEDIA REPLENISHING SYSTEM This system includes a 4 cubic foot capacity make-up hopper, an automatic “Sure-Flo” feed valve, and media level sensor with indicator light.
The “Sure-Flo” feed valve on the make-up hopper will open to add media to the system if the media in the pressure vessel is not at the proper level. The “In Refill” light will be illuminated during the refill process. The make-up hopper will have a low media level sensor and a “Make Up Hopper Low” light. This light will be illuminated when the make up hopper needs to be filled with media. As the media breaks down and is drawn to the dust collector, fresh media of the proper size will mix with reclaimed media. This ensures a consistent working mix of media and produces a repeatable finish.
