WEIGH BATCHERS
The 3 Most Popular Vibrators
VS-320 55-1-1/4 US-450
Silent Turbine Pneumatic Piston Pneumatic 115 Volt Electric
VIBRATORS TO USE:
1. Electric - Model US-450
Advantages:
  • Easy to install, connects to any electrical light outlet.
  • Only draws 3 amps at 115 volt.
  • Will Outlast Pneumatic Units 3 to 1.
  • Quiet Operation.
  • Can be connected to gate control for automatic on-off.
  • Can be repaired in the field.

    Considerations:
  • Initial cost higher than a pneumatic unit, but low maintenance & life more than makes up for the initial price.
  • Maintenance wise the brushes need to be changed every 1000 hours for normal use & 6-700 hours for repeated stop and start duty.

    2. Pneumatic - Turbine Vibrators Model VS-320
    Advantages:
  • Needs no lubrication - bearings prelubricated for life.
  • Absoultely quiet.
  • 72-75 dB no more noise than an electric motor.
  • Air consumption less than ball vibrators.
  • Outlasts ball roller and piston vibrators 3 to 1.
  • Can be repaired in the field, repair kits available.
    		•  2. Pneumatic - Turbine (cont.)
    Considerations:
  • Need 3/8" air hose instead of 1/4" hose used by equivalent piston vibrator.

    3. Piston Vibrators - Model 55-1/4"
    Advantages:
  • Use less air to operate than any other pneumatic vibrator.
  • Lowest in cost of the pneumatic.

    Considerations:
  • MUST be lubricated - works on the same principle as the piston in a car, must have oil or they seize.
  • Must have relatively clean air - an air cleaner in the line is necessary. A mixture of oil and water in the air line creates a lapping compound and will make the piston seize.
  • Noisey - is the loudest of all vibrators 85-90dB.
  • Cannot be repaired in the field. Repair cost can be almost as much as a new unit.

    4. Ball Vibrator - Model V-320
    Considerations:
  • Must have continuous lubrication or it will wear out fast and noise becomes ear shattering.
  • Looses efficiency fast, especially if lubrication is insufficient.
    		•

    Many other vibrator models can be used but they have other considerations than the above listed ones or are more expensive. Considering the operating cost and life & repair cost of unit, on a long term basis, Model US-450 is the best buy. Second is Model VS-320, then Model 55-1-1/4".

    ENGINEERING DATA
    & APPLICATIONS    		 > WEIGH BATCHERS
    MODEL US-450 KEEPS CEMENT FLOWING.
    PROBLEM: Dry Portland Cement would cling to weigh batcher, and hopper sides. A 2 x 4 was used to get flow going and clean sides:
    SOLUTION: Model US-450 high frequency vibrator was mounted to channel iron that was welded to side of hopper. The high frequency vibration and force loosened the cement and made it flow easily and cleanout was made in a few seconds.

    PORTABLE BATCH READY
    MIX PLANT
    To insure fast and accurate batching and reduce noise a Model VS-320 Pneumatic Silent Turbine vibrator was installed on Weigh Batcher.

    INSTALLATION
    Any one of these vibrators (Model US-450, VS-320, 55-1/4", and V-320) can be used on bins and hoppers. High frequency over 5000 vibrations per minute are most effective for light fluffy materials, cement, etc.

    RULE OF THUMB FOR SIZING: Figure out total weight in pounds of material insloping, conical part of bin. Divide by 10, the figure is the total force needed on the vibrator or vibrators to be selected. See General Catalog page 11-12 for technical data on Model US-450.
    US-VIBRATORS AT WORK
    CUSTOMER: Ready-Mix plant
     
    APPLICATION: Cement weigh-batcher
     
    PROBLEM: VIBCO US-450T, 115 volt totally enclosed electric vibrator was mounted to batcher (see picture and mounting diagram). Vibrator location for fine cement dust is 1/4 up side with least slope.* The 4" mounting channel is 3' long, stitch welded to 1/4" batcher skin. **The operator switches handy vibrator switch "on" when discharging cement into transit-mix, truck and turns US-450T "off" when dial scale reads zero.
     
    RESULT: Reliable mixes, delivered on time! This VIBCO vibrator in operation over four years without maintenance to unit, batcher or scale. Also, batcher stays whistle-clean inside with no built up cement to chip off at maintenance time.
     
    PNEUMATIC
    UNITS:    		 Comparable pneumatic vibrators are the VS-320, 55-¼, on thick walled hoppers, the SVRF-4000.
     
    *On coarser materials vibrator is placed about 1/3 up side wall.
    **Use longer channel (up to 7') for thinner walls; for plates over 3/8" use 1-2" long channel.
