DESIGN FEATURES

Advanced structural design and bowl shape: Improves processing efficiency, durability, and machine life.  Bowl has a small rise immediately prior to the discharge gate.

Certified, pressure-vessel materials used to construct bowl supporting chamber:  Constructed from 3/8" to 9/16" steel to provide high tensile strength and high yield strength.

Polyurethane lining:  Is cast, not sprayed on.  This improves media rebound and provides more wear depth.

Higher amplitude:  Ensures optimum processing capabilities.

Low profile:  Permits convenient access to process controls, media and parts.

Low power requirements:  Reduces costs and increases the working life of the system.  Balanced chamber and angled springs permit optimum energy use.  Lining is canted to improve mass roll and efficiency on larger models.

STANDARD OPERATING FEATURES 

Unique cartridge drive system: Minimizes vibration to the motor and maximizes the working life of

Unique cartridge drive system with adjustable drop on eccentric weight system

the drive system.  Designed for easy installation and service.  Two (2) hours or less changeover and our exchange program with in-stock availability make our drive system user friendly and cost effective.  Easy access to all seals.  All seals rotate with shaft to prolong working life.

Adjustable, drop-on eccentric weight system:  Provides quick, simple vibration adjustment to optimize processing time and media/parts separation.  Weight segments are located on each end of a vertical shaft.  An index plate at the top shaft-end has numbered holes to permit selection and repeatability of desired settings.  No tools are required for adjustment on standard weight systems.

Built-in parts/media separation:  Provides rapid, reliable separation of media and processed parts.  Separating gate is built into the process channel and is controlled by manual lever or pneumatic cylinder (which can be timer-operated.) When the separating gate is raised, the contents of the processing channel go straight out over the screen deck.  The media drops back into the process channel and finished parts move to a collection point or to the next production station.

Continuously monitored oil recirculation

Continuously-monitored oil recirculation:  Ensures that the entire system is getting oiled.  Tied into control panel to prevent start-up without adequate lubrication.

Compound flow-through system:  Provides automatic mixing and metering of compound and water to ensure maximum cleanliness of media and parts.  System is composed of an electrically-operated variable-delivery compound pump that injects the concentrate into a controlled-flow water line.

Multiple pop-in drains:  Carry away soiled solution and simultaneously remove debris, including metal chips, and particulate.  Interchangeable drains of molded polyurethane are available in a variety of opening sizes and shapes to meet specific processing requirements.

Compact settling tank

Compact settling tank:  Serves as a solution settling tank for larger particles.  Easy to cleanout.  Also serves as a platform to provide easy access to process settings and amplitude weights.

Manual lever or pneumatic operated gate:  Allows for batch-type operations where more than once-around processing is desired.

Quick-change screen decks:  Permit the widest variety of deck patterns to meet all separation requirements.  Deck materials include woven wire, cast polyurethane reverse angle, tyrod or tie bar, plus variations and combinations to meet specific requirements.

Limit Switch on hinged door

Limit switches at all hinged access doors:  Automatically shut down machine when access doors are opened, for operator safety.  (Does not apply to the Spiratron® ER-2 or Gemini Series).

Controls:  Include fusible disconnect, 110V. control circuit completely pre-wired to the machine.  Totalizing hour meter.  Safety switches on hinged access doors.  Digital process timers standard on most models.

OPTIONAL FEATURES

Parts load chute:  Allows for parts loading directly under the parts separation screen.  Allows for maximum machine utilization.

Pneumatic gate:  Allows for power assist.  (Standard on E.R. Series machines 10 cu. ft. and larger.

Dual cylinder gate:  Minimizes part impingement during gate clearing.

Gate clearing:  To prevent parts from being trapped between the gate and screen during the separation process.

Internal wrap-around separation screen and frame:  Increases the amount of screening area available without requiring additional floor space.

External wrap-around separation screen and frame:  Increases the amount of screening area available while allowing easy access to the main process channel.

Media retrieval screen:  Designed to be used in drying units to retrieve processing media, slugs, etc.

Media classification screen:  Designed to remove processing media, slugs, etc., from processing chamber at a predetermined size to minimize media lodging in parts being processed.

Inverse separation screen:  Designed for separation involving parts that are smaller than the processing media.  May also be used for media size maintenance on a scheduled basis.

2" step in screen:  Helps turn parts to assist in removal of media from possible entrapment areas.

Feed-to feature:  Required to transfer parts from one Spiratron® to another when machines are assembled in a series-type system.

Rinse station:  Allows exiting parts to be rinsed with a spray of fresh water.  Located at the end of the separation screen frame, nozzles are placed to provide an even complete rinse.

Curved Wall Lining

Curved wall lining:  Prevents light parts from floating on mass and enhances processing speed.

Recirculating inhibit station:  Allows exiting parts to be rinsed with a spray of solution containing an inhibitor to retard oxidation.  The solution is recycled allowing the inhibiting solution to be reused.  Includes:  38 gallon storage tank, 1/3 HP solution pump, solution level float control, compound makeup pump and water makeup with flow meter for proper inhibiting compound concentration.

Flexible fabric noise cover:  Constructed of sound absorbing material between two layers of rubberized canvas.  The cover is securely fastened to the center tube of the machine and is draped across the top of the processing chamber, and is designed to allow free access to any section of the chamber.  The standard Roto-Finish noise cover will reduce the noise level by approximately 2 to 6 dbA.  The major source of noise is from the interaction of media and parts; therefore, we are unable to give exact dbA readings.  Special noise abatement enclosures are available.

Aluminum noise cover

Aluminum noise cover:  This cover consists of an aluminum fabrication connected to a counter-balanced cantilevered arm.  Sound absorbing material is open-cell urethane plastic foam at a density of 2.0 pounds per cubic foot.  Foam is applied 3" thick to the interior of the sound cover.  The exterior is painted Roto-Finish std. color.

Hardened steel drain screens:  For proper drainage when extremely small media is required for processing.  The accurately machined slots or holes retain expensive media in the process bowl while allowing for solution drainage.

120 durometer polyurethane pop-in drains.

Additional drains in each chamber.

Magnetic separator with stand:  Used when ferrous parts and deburring media size are near equal preventing separation using normal screening methods.  Consists of a special slider bed conveyor suspended above the discharge gate of the Spiratron®.  The primary rotating drum contains permanent magnets that attract the ferrous parts allowing the non-magnetic media to return to the processing bowl.  Parts are then transferred out over the top of the neoprene belt to waiting containers.

Magnetic separator with stand and flat plate demagnetizer:  Is used when ferrous parts and deburring media size are near equal preventing separation using normal screening methods.  Consists of special slider bed conveyor suspended above the discharge gate of the Spiratron®.  Primary rotating drum contains permanent magnets that attract the ferrous parts allowing the non-magnetic media to return to the processing bowl.  Parts are transferred out over the top of the neoprene belt.  A flat plate demagnetizing unit is located under the belt between the head and tail pulley providing a demagnetizing field that the parts must pass through before being transferred to waiting containers.

E.R. SERIES VIBRATORY EQUIPMENT SPECIFICATIONS

Calculating Machine Capacity There is a tremendous amount of variability, throughout the industry, in the way machine capacity is computed. For your reference, all Spiratron ER Series machines carry machine capacity figures based on the following formula, where C = width of the processing channel and H = center column diameter:

Capacity = (C² * (H + C))/778
