OA Series
OA Series Gravimetric Blender
OA Series Gravimetric Batch Blending System features precision auger metering of all ingredients. OA blenders are perfect for applications that require multiple regrind materials or materials that are difficult to meter.
Each OA blender features machined metering augers, precision load cells, cast aluminum feed auger assemblies and heavy-duty industrial design. The OA Series offers superior batch control and reliable feeding of difficult materials.
REQUEST A QUOTE Find a rep- The OA Series is well suited for plastics processing applications that require accurate batch blending, particularly those involving multiple regrind materials or materials that are difficult to meter consistently.
- The OA Series utilizes precision auger metering for all ingredients, allowing it to accurately process difficult-to-meter materials and multiple regrind streams. This design helps provide reliable feeding performance and consistent blend ratios from batch to batch.
- The OA Series utilizes a precision offset cantilever load cell with 0.02% span accuracy, helping ensure accurate ingredient measurement and consistent batch-to-batch blending performance.
- The OA Series uses machined metering augers and precision load cells to control and verify material delivery. Standard models feature constant-speed AC gearmotors, while optional variable-speed DC drives are available for enhanced feeding flexibility.
- The OA Series offers three recipe entry methods: Percentage recipe entry, 8-component EZ Mode recipe entry, parts mode ratio recipe entry
- These options provide flexibility for a variety of blending and material management requirements.
- The OA Series incorporates an HC mixer design on select models to promote material homogeneity throughout the batch. Combined with precision auger metering and target-versus-actual setpoint verification, this helps support consistent blend quality.
- Yes. The OA Series includes a compressed-air cleanout hose with blowoff tool and drain tubes below each feeder housing for quick material removal during cleaning, maintenance, and material changeovers.
- Yes. The OA Series offers numerous optional features, including larger HMI screens, variable-speed drive motors, material shut-off gates, stainless steel hoppers, agitated regrind hoppers, low-level sensors, vacuum take-off boxes, cleanout doors, and multiple stand configurations to support a variety of processing requirements.
- PLC-Based control system with color touch-screen inteface. English or metric display, 8’ cable, serial printer port, and 3 entry modes:
- Percentage recipe entry–Ingredients metered as a percentage of the batch
- 8-component “EZ” mode recipe entry–color and additives metered as a percentage of the virgin
- “Parts” mode ratio recipe entry (i.e. 500:1)
- Precision auger feeding of all materials with constant speed AC gearmotor. Variable speed DC is optional
- “HC” mixer design promotes homogeneity (012 & 060)
- Precision .02% span-accurate offset cantilever load cell
- Convenient compressed air clean-out hose with blowoff tool
- Drain tube below each feeder housing for quick draining
- Target versus actual set point verification
- Safety-interlocked access that shuts off both air supply and electricity if blender is opened
- Alarm output
- Hopper lids arranged for AEC receivers and loaders
- 10” Color HMI touch screen upgrade in lieu of standard 7”
- 12” high extension for major ingredient hoppers
- SCR variable-speed DC drive motor in lieu of standard constant-speed AC motor
- Material shut-off gates above feeder housing
- Mezzanine, drum-fill, or gaylord-fill blender stands
- Stainless steel material supply hoppers
- Agitated straight wall regrind hopper with gear motor
- Low-level solid-state proximity sensor for each supply hopper
- Low-profile drawer magnet (3 bar)
- Vacuum take-off boxes mounted below the floor stand
- Premium aluminum spool mounting flange with drain port, 8” x 8” square
- Clean-out doors in spun material supply hoppers, including safety grate or lock-out safety switch
