CENTRIFUGAL BLAST WHEEL

WHEEL: An efficiently designed single-sided blast wheel minimizes the overhung load on the motor and reduces the time required to change blades, impellers, and control cage. The standard blast wheel measures 12” in diameter and features seven curved blades for optimal abrasive control. All components are balanced to ensure smooth operation. With a high horsepower-to-weight ratio, this system enhances abrasive delivery efficiency per unit of horsepower.

MOTOR: Direct drive motor revolves at 3600 RPM. Taper lock brushed motor shaft with NEMA tolerance.

BLADES: Our innovative Snap Lock system simplifies blade replacement without the need for tools. Crafted from abrasion-resistant alloy in our in-house foundry, our curved blades offer optimal abrasive control. Cardinal shot blast wheels allow for effortless blade replacement in sizes 12”, 13.5”, or 15”, enhancing shot velocity and increasing versatility.

CONTROL CAGE: Dial type cage for ease of targeting the abrasive flow. 

WHEEL HOUSING: Our wheel housings are made from durable steel plate and are fully lined with replaceable cast chrome manganese alloy liners produced in our own foundry.

MILL CONSTRUCTION

CONVEYOR: our premium Continuous Molded Rubber Tumble Belt, featuring a durable 3-ply construction, standard 5/16” diameter abrasive drain holes, and rubber tumbling ridges for enhanced performance, variable speed drive. Customize your setup with a range of optional drain hole sizes to suit your specific needs. 

CONVEYOR ROLLERS: Our robust Heavy Duty Rollers boast sturdy 1-7/16” solid shafts and are secured to the cabinet with standard 4-bolt flange bearings for optimal stability.

LINERS:  The 24” diameter barrel heads are crafted from 3/8” abrasive-resistant steel, complemented by tight-sealing cabinet liners that are easily removable for convenient belt access. Explore the optional cast liner package to further enhance your setup and elevate your machine durability and performance. 

CONVEYOR SPEED: 12 FT/MIN, variable speed available

CAPACITY: 31” wide by 24” diameter mill will handle 3.0 cubic feet or 400 pounds. 

CABINET CONSTRUCTION

CABINET: Crafted from durable 1/4” steel plate, our cabinet construction promises unparalleled durability and reliability. Thoughtfully designed access holes on the sides make belt and liner replacement a breeze, enhancing maintenance efficiency. Additionally, tramp metal is effectively captured on lower abrasive screens, ensuring that large debris is meticulously filtered out before it can reach the abrasive hopper, maintaining optimal blasting performance and equipment longevity.

DOOR: Air operated power lock. 1/4” abrasive resistant door.  

ABRASIVE RECYCLING SYSTEM

ELEVATOR: The bucket elevator system features cast iron sheaves and metal-stamped buckets. Our design ensures precise tracking and simple adjustments by employing a heavy-duty C-section banded V-belt elevator belt with a multi-cord construction. The abrasive shot blast media is transported by the metal-stamped buckets to the hopper situated above the machine. All of our shot blast media hoppers come with a screen to prevent larger debris from entering the shot blast wheel.

ABRASIVE CONTROL VALVE: Totally enclosed butterfly valves are air cylinder operated. Fully adjustable for abrasive flow control.

ABRASIVE SEPARATOR: The Single 12” Lip Separator, also known as a media air wash, efficiently removes fines and dust from blasting media, ensuring only clean, heavy media is recycled through the shot blast wheel. As media is returned to the hopper above the blast wheel, it spreads into a waterfall, creating a thin blanket of flowing media. A dust collector then pulls air across this stream, eliminating unwanted particles and allowing clean media to return to the abrasive hopper, ready for reuse. This process maintains high-quality blasting media, enhancing the effectiveness and longevity of the blasting operation.

ABRASIVE REQUIRED: 400 pounds.
 

VENTILATION

DUST COLLECTION: Effectively eliminates dust-laden air from the machine, ensuring a cleaner work environment. It incorporates a single 12-inch lip separator that efficiently separates fines and dust from larger abrasives, keeping the media clean as it is returned to the blast system. The machine requires an 800 CFM dust collector, sold separately. Collector control circuit pre-wired on all Cardinal Shot blasters for easy integration. 

ELECTRICAL CONTROLS

CONTROL PANEL:

• Type 12 electrical enclosure.
• Thermal overload protection for all motors.
• Standard 230/460 volt ammeter.
• Oil tight push button controls.
• Timer controls the abrasive flow.
• Touch Screen PLC Controls.

SAFETY FEATURES: The blast wheel operates exclusively when the door is shut. An air lock mechanism ensures that the cabinet door remains securely closed throughout the blasting process. With an adjustable time delay feature, the flow of abrasives serves as a brake on the blast wheel before the door can be safely opened.

ELECTRIC MOTORS: All motors are totally enclosed, and fan cooled to provide maximum life. Optional 230/460 volt 3-phase.
