AVAILABLE MODELS All VENTURI LOADER MODELS use our aluminum venturi vacuum generator. MPL series loaders: • • • Are built on a two inch steel bar for easy mounting to the frame of a concentrate feeder or Weigh Scale Blender. The air solenoid is visible on the bar. Only ONE venturi loader can be controlled. MPL-A has a control box with ALARM Strobe light and beeper. MPL-AS uses the same control box with an additional time delayed solenoid to activate a shut down procedure in the event the ALARM goes unattended. ML series loaders: • • • • Do not use a steel bar for mounting. The air solenoids...

PARTS SUPPLIED All MODELS: 1. Aluminum VACUUM GENERATOR, mounts directly to the material pickup lance. 2. MATERIAL PICK-UP LANCE. 3. MATERIAL TRANSFER LINES: a) Suction line (12 feet of 1 inch flexible hose). b) Material pick-up lance (aluminum). 4. AIR LINE (Plastic) to connect the air solenoid to the Vacuum Generator. 5. HOPPER LID PARTS: On MICRO blender series, (ML-1M), a complete new lid is provided with filtered receiver box. All others, a PELLET DEFLECTOR box is provided to mount inside the hopper lid to accept the inflow of material. 6. SENSOR MOUNT (red polypropylene) installs in...

ASSEMBLY (Refer to diagrams) MPL series: 1. Attach the Steel SUPPORT BAR to the ADAPTOR FRAME as shown in Figure A. To do so, remove one bolt, slide clamping bar behind two corner angles; re-install bolt and tighten. On a concentrate feeder, the bar attaches to the REAR of the adaptor frame and extends BEHIND the controller. All Models: 2. Mount the deflector and connection stub tube to the hopper lid as shown in Figure B. NOTE: OLDER HOPPER LIDS: If this unit is being added to an older hopper lid, you must first add the new hole pattern to your existing hopper lid. The hole pattern is...

MOUNTING CONTROL BOXES (all models except MPL) On MCF AUGER FEEDERS: If this loader to be used with an MCF concentrate feeder, attach the control box to the end of the Feeder control box as shown in Figure A. This can be done using the existing sheet metal screws in the MCF controller. WEIGH SCALE BLENDERS: If this loader is to be used with a Weigh Scale Blender FEEDER, then a bracket is provided. Bolt this bracket to the plate that is mounted under the auger feeder drive motor and then bolt the loader control box to the bracket. This is shown in Figure C. MICRO BLENDERS and OTHER...

OPERATION When material level in the hopper drops enough to uncover the sensor, the air solenoid is turned on. High pressure air passing through the vacuum generator creates a high volume, low pressure, flow of air into the hopper. This flow of air pulls material from the source and conveys it into the hopper. A steel plate in the hopper serves to deflect the blast of pellets and slow their speed. This prevents high speed bouncing of pellets in the hopper, keeping them from escaping under the edges of the hopper lid. The Air stream is expected to escape from the hopper by passing under the...

CONTROLS MODEL MPL: has no control box. Loading is simply controlled by uncovering the sensor. MODELS MPL-A and MPL-AS: 1. SWITCHES: LEFT switch is the LOADER control. MIDDLE switch is the ALARM control. RIGHT switch is the optional process SHUT-DOWN control. This "shut-down" function requires an air operated mechanical shut-off device mounted to an adaptor frame (as supplied standard with our concentrate feeders). When energized, this will stop the flow of natural material to the process. 2. SWITCH POSITIONS: UP for automatic operation. MIDDLE position to prevent operation of the...

ADJUSTMENTS 1. AIR FLOW CONTROL VALVE: The idea is to use as little air as possible and still convey pellets. Conveying can occur with as little as 20 PSI air. Read and adjust the pressure gauge WHILE CONVEYING, to determine correct conveying pressure. If pressure drops too low for proper operation, the diameter of the AIR SUPPLY line is TOO SMALL. Too much air flow wastes air and may create dust problems. Pellets may bounce out of the hopper from under the lid. A very low flow of air may not convey pellets properly. Use just enough air to ensure a steady continuous flow. 2. LEVEL SENSOR:...
