GOFF Skew Roll Rod Blaster

Airless Blast Unit

Wheels:

• The blast wheels are directly driven by a 3600 RPM motor for maximum abrasive velocity. The blast wheels are Goff’s 12” diameter wheel with 8 curved blades that are 3” wide. Blast wheels can be operated separately or in conjunction. All revolving wheel components are balanced for smooth operation.

Blades:

• Unique interlocking design eases blade replacement. Cast from abrasive resistant alloy to assure maximum life. Curved blade design provides for maximum abrasive control.

Control Cage:

• The dial type cage gives positive adjustment of blast patterns. Cast alloy steel constructed.

Wheel Housing:

• Fabricated from 1/4” steel plate. Housing is lined with 7/8” cast interlocking abrasive resistant liners.

Cabinet Construction 

Cabinet:

• Pitless type, all welded structurally reinforced cabinet is fabricated from 1/2” abrasive resistant plate in the blast area.

Work Table:

 • 52” diameter work table is constructed of 1/2” steel plate and is covered with a removable abrasive resistant liner. Table revolves on a 2” diameter shaft supported by a thrust bearing. Table revolves on a 2” diameter shaft supported by a thrust bearing. Maximum load capacity of table is 4,000 pounds and revolves at 7 RPM.

Cabinet Construction

Cabinet:

Pitless type, all welded structurally reinforced cabinet is fabricated from 1/2” steel plate. Large access doors at rear of cabinet permit periodic inspection and maintenance.

Access Door:

• A large access door has been provided to service the interior of he cabinet. A safety interlock prevents the operation of the blast wheel if the door is ajar. The door is constructed from abrasive resistant alloy steel.

WORK CONVEYOR

Work Travel Control:

• Work to be blasted is conveyed and rotated by a skew roll conveyor. Work flow rate through the machine is controlled by VFD.

Conveyor:

• Ten feet of skew roll conveyor complete with drive components and supporting structure feed the material into the blast cabinet. Ten feet of discharge conveyor is also included. The rollers are mounted on one inch solid shafts positioned in lubricated for life pillow block bearings.

 

Skew Rolls:

Made from Heat treated alloy steel for abrasive resistance.

Conveyor Drive:

• A common SCR drive control system powers the external and internal roller conveyor. Each roller is powered by a round urethane belt providing a high coefficient of friction to drive rollers. The direct drive system in the blast zone is protected from blast by 1/4” heat treated alloy steel plate. Regulation chain guards are provided.

 

Abrasive Seal:

• Removable and interchangeable vestibules on ingress and egress provide a positive deterrent to flying abrasive. The design utilizes a triple seal arrangement of 1/8” resistant rubber.
