New 72" Dura Blast Rotary Shot Blast

At Plan B, we know we can build a blast machine as cheap or cheaper than any of our
competitors, but we choose not to. Harder steel, quality castings, smart designs,
maintenance friendly, and modern technology, make for one of the best standard machines you can buy.
Please see the following equipment proposal for your blast cleaning application.
The enclosed information describes the Dura-Blast 72” Table Wheel Blast with standard
features. The machine is considered a plug and play system and is easily moved by utilizing the built-in fork pockets to locate the machine. It is a free-standing cabinet that has a heavy duty, lined, 72” table with a 6000 lb. capacity for material handling. It has one direct drive 20HP, 7-blade blast wheel, and can be matched with one of our 2000 CFM dust collectors. The PLC/Touch Screen controlled, electrical panel is mounted on the side of the cabinet and is protected by vibration dampening mounts.
We utilize a double elevator system to fully air-wash all the abrasive thrown by the blast wheel. The two-belt system allows us to keep the air-wash and screen clean-out at eye level, so it is easier to adjust and maintain. This design also allows us to keep the overall height to a minimum, by removing the air-wash from above the hopper.
Many of our “standard” features are add-ons and upcharges with other manufacturers,
so pay close attention to quotes on similar machines, to see what you are getting for
your money.

We provide a one-year warranty, full technical support, and readily available replacement
parts.

General Description
Your DuraBlast 72 Table consists of a 72” diameter worktable constructed of ½” steel
plate
with an abrasive-resistant liner. In brief, the 72” Table Blast operates as follows:
Abrasive is fed into a 20HP Direct-Drive Blast Wheel. The Blast Wheel, revolving at
3600 RPM, throws abrasive at the work surface with tremendous velocity. The worktable
rotating at a speed of 4 RPM assures exposure of parts to the blast stream.
The abrasive is swept from under and around the table and out of the cabinet where it is picked up by the primary elevator and is deposited into the air-wash separator where the abrasive is cleaned. The air-wash separator removes contaminants from cycling abrasive and deposits the clean abrasive into the secondary elevator where it is conveyed to the abrasive storage hopper. The hopper has the capacity to store enough clean abrasive to maintain an even flow to the blast wheel.

SPECIFICATIONS – DURABLAST 72” TABLE
CENTRIFUGAL BLAST WHEEL
Wheel: The direct drive blast wheel revolves at 3600 RPM for maximum abrasive velocity.
The blast wheel is available in 12”, 13.5” and 15” diameters. Balanced wheel components assure smooth operation.
Blades: Long life, abrasive resistant cast alloy blades, matched by weight for proper
wheel balance.
Control Cage: Dial type cage.
Blast Wheel Housing: Available in ¼” mild steel, AR steel, or manganese steel. All liners
are replaceable.

CABINET CONSTRUCTION
Outer Cabinet: AR 500 construction, fork truck pockets for easy placement.
Cabinet Lining: Replaceable cast alloy liners in direct blast area, options to fully line the blast cabinet area, or just line certain areas as needed.
Worktable: 72” diameter worktable is constructed of 1/2” steel plate. Table liner is
3/8” abrasive resistant steel. Cabinet cutout makes worktable accessible by overhead
hoist.
Heavy duty table support bearings are completely enclosed for protection from stray
abrasive.
Table Drive: Chain driven by an electric motor and gear reducer located under the table.
Table revolves at 4 RPM.
Double-Lock Door: Our 72-table door has both a pneumatically operated air cylinder clamp, and a pneumatically operated vertical door pin. If power or air is cut to the machine, the door cannot open, and we integrate a timer in case the E-Stop is activated, so you must wait for the wheel to slow down before you can open the door. Rubber door seal helps prevent abrasive escape. A mangalloy door skin helps reduce wear on the inside of the door and does away with unwanted rubber liners.
Work Loading Height: 36”
Maximum Working Dimensions: 72” diameter, 19” high at edge of table and 37” height at
center of table.
Workload Capacity: 6,000 pounds.

ABRASIVE CLEANING & RECOVERY SYSTEM

Elevator and Air Wash: Double V-belt system that carries the abrasive to an
adjustable, eye-level separator where 100% of the abrasive is air washed,
then cleaned abrasive is carried up to the abrasive storage hopper for feeding of
the blastwheel. Easy access screens are in place to help keep larger, foreign
items from damaging the blast wheel components. Elevator belts are adjustable to
prevent the belts from slipping as they wear.
Abrasive Flow: Manually adjustable, butterfly type abrasive valve for setting
blast wheel amperage and controlling abrasive flow. Optional Magna-Valve available
for automatic adjustment with different abrasives or Shot Peening use.

Abrasives: Most standard shot or grit type abrasives can be used, and the initial
abrasive charge is 1500 lbs.

Dust Collector: Adjustable reverse pulse, 10 cartridge collector, standard
Magnehelic gauge, with options available.

Separator: 14” gravity lip has adjustable abrasive spreader and refuse gate
for maximum contaminate removal.
