USF Spencer Halstead Model CB75 Through Feed Shot Blast Machine Overview

Parts are loaded with a powered lift assisting Jigs at both ends of the loading table.

Metered abrasive flows by gravity from an overhead storage hopper, through a feed spout and into a rotatingimpeller in the centre of the blast wheel assembly.The impeller directs the abrasive through an opening in theimpeller case and into the rotating vanes of the blast wheel.

The blast wheel throws the abrasive by centrifugal force, against the work to be cleaned.

After striking the work the abrasive falls into a recovery hopper, along with contaminants such as sand, scale etc.,which has been removed from the work piece.

The abrasive handling system lifts the contaminated abrasive up to the separator, above the machine.

The separator removes the contaminants and any abrasive particles that have become too small to beuseful Cleaned and sized abrasive is now returned to the storage hopper for re-use, completing the cycle.

USF (Wheelabrator) CB75 Through Feed Shot Blast Machine

TECHNICAL DATA

Material to be cleaned - Mild steel, straight, flat, dry and oil free

Maximum plate width - 750 mm

Plate thickness - 6 to 25 mm

Rolled steel sections - Angles, channels, tubes, hollow sections and beams up to 457 mm high in "I" configuration

Performance - Cleaning speed will be dependant upon finish required and condition of component prior to blasting.Small sections can be handled in multiples, correctly positioned to avoid masking.

The machine is designed for single pass cleaning over a wide range of components. Some components may require2 pass due to size and configuration.

Cleaning rate (A or BSa 2.5) - Plates, flats up to 2.3 m/min. Sections at approximately 30% to 75% of plate speeddepending on type and size.

Maximum conveyor loading - 100 kg per linear metre

Minimum work length - 1250 mm

Conveyor speed - 0.43 to 2.58 m/min (reversible)

Number of blast wheels - 4Blast wheel power - 7.5 kw each

Blast wheel speed - 3000 rpm

Abrasive capacity - 6554 kg/hr/wheel

Separator type - Airwash

Separator size - No 600

Separator airwash area - 0.9 m2

Ventilation requirement -1275 m3 per hour

Installation - Inside building on flat concrete floor to give 1125 mm nominal roller height.

USF (Wheelabrator) CB75 Through Feed Shot Blast MachineNOTEEstimated production is based on mild steel of an "A" to "B" initial surface condition to S.a. 2.5 degree of finish asdefined by Swedish Standard S.I.S. 055900. If the surface condition is more severe, or if a more tenacious scalecondition than normally found on mild steel is encountered, or if a greater degree of cleaning is required, a reducedspeed will be required to achieve the desired degree of surface finish.

CABINETInlet vestibule manufactured from manganese plate and suitably stiffened. The area adjacent to the blastcompartment is lined with manganese steel plate. Multiple sealing curtains are provided to minimise abrasiveescape.Blast compartment manufactured from manganese plate. Periphery lined with manganese welded in.

Outlet vestibule manufactured from manganese plate and suitably stiffened, provided with multi split rubber sealingcurtains to minimise abrasive escape.Integral with cabinet is an abrasive return hopper terminating at spiral trough.

INTERNAL WORK ROLLERSSix rollers each comprising of a steel shaft with turned down ends carried in protected self lube ball bearingsmounted outside the cabinet housing, location rings provided. Rollers connected together by guarded chain drives.Seals provided to protect bearings.

One roller shaft connected to variable speed geared motor unit, speed adjusted manually from control panel.

EUROVANE BLAST WHEELSFour - SH35 type Eurovane 350 mm diameter blast wheels. More efficient, more effective, better results.

The new Eurovane shotblast wheel is the result of over forty years experience in the design of abrasive throwingsystems and is without doubt the most advanced of its kind currently available.

The performance of the wheel being so critical to the efficiency of the machine, our engineers reconsidered everyaspect of its construction, material, maintenance and operational environment , both theoretical and practical undertest conditions.

Advanced features of the Eurovane wheel system which you should consider are:

Forward curved vanes on each of the eight vanes. These are carefully calculated to give the optimum throwingpower, with minimum energy, noise generation and wear.Location system suitable for both clock and counter clockwise vanes, no need to stock both.High quality, precisioncast vanes and other component parts from our own foundries for maximum life and efficiency.All Eurovane wheelparts and housing liners manufactured in 28% chromium for long operational life.Maximum power adjustable blaststream with almost total elimination of the shifting stream trend common to conventional wheels.All giving longer lifeand greater efficiency than conventional wheels.

ABRASIVE HANDLING AND RECLAMATION SYSTEMTo provide full mechanical and continuous abrasive handling by use of gravity hopper to feed:

USF (Wheelabrator) CB75 Through Feed Shot Blast MachineBOTTOM SPIRALOne steel plate blade spiral mounted on tubular shaft fitted with stub ends carried in protected, self lube type ballbearings mounted outside casing. Driven by geared motor unit. Abrasive discharged into elevator boot.

ABRASIVE ELEVATORBelt and bucket abrasive elevator, completely steel encased, dust and abrasive tight, with drive at elevator head.Take up at elevator head provides proper tensioning of elevator belt. Elevator belt of special construction withcorrectly spaced buckets. Abrasive elevator discharges spent abrasive and refuse to:

ABRASIVE SEPARATOR

One airwash abrasive separator having a separation length of 600 mm.

Used abrasive and fines refuse are stored behind the fixed, but adjustable metering gate and is allowed to fall in auniform curtain through the airwash separation zone.

Features of this airwash section include:

Adjustable metering gate, set and locked in position to provide uniform curtain thickness and uniform density ofmaterial flow.Airwash and separation zone is 152 mm high to allow space for efficient separation of good abrasiveand fine refuse.Air velocity control plate located in the first separation zone.An adjustable skimmer plate removesfines material.A screen is provided for trapping out coarse particles.Only good, usable abrasive flows to the storagehopper.

ABRASIVE STORAGE HOPPEROne steel plate abrasive storage hopper, located under the abrasive separator for storing cleaned abrasive. An airoperated gate is located under the storage hopper for controlling the abrasive flow to the blast wheel units via aseries of feed pipes. The abrasive control gate is operated by means of an air cylinder and solenoid valve.

ABRASIVE GATE CONTROLAbrasive gate operated by selector switch from main control panel. Blasting is possible in either forward or reversedirection.

MOTORSContinuously rated T.E.F.V. squirrel cage, class ' F' insulation. Manufactured to metric range dimensions. Suitablefor use in ambient temperatures not exceeding 400°C and at altitudes up to 1000 above sea level. Can be suppliedspecially rated for use in higher ambient temperatures or at high altitudes at extra cost.
