WEIGH BATCHERS The 3 Most Popular Vibrators VS-320 SILENT TURBINE PNEUMATIC 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 & long life more than makes up for initial price • Maintenance wise the brushes need to be changed every 1000 hours for normal use & 600-700 hours...

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. MODEL VS-320 on portable batch ready mix plant To insure fast and accurate batching and reduce noise a Model VS-320 Pneumatic Silent Turbine vibrator was...

ENGINEERING DATA \ WEIGH BATCHERS Any one of the vibrators listed on page 2 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 Model US-450 under High Frequency Vibrators. CUSTOMER: Ready-Mix plant APPLICATION: Cement weigh-batcher PROBLEM: VIBCO US-450T, 115 volt totally enclosed...

CEMENT SILOS Most Popular Vibrators Cement reacts well to a vibrator frequency of 3600 vibrations per minute or higher. The high frequency vibration helps to aerate the cement and make it flow freely. Rotary vibrators churn the cement and are better to use than piston and electro-magnetic vibrators that have a tendency to pack the cement. 1. To select the proper size vibrator, calculate the total weight of the material in the sloping part of the silo only. For rectangular bins: (dimensions in feet): Length x Width x Height x 1/3 x Material Density in Lbs./Cu.Ft. For conical bins: .261 Dia2...

ENGINEERING DATA & APPLICATIONS CEMENT SILOS PROBLEM: Cement hung up above chute coming out of hopper SOLUTION: Model US-1600 Electric Vibrator 115 Volt was installed 1/4 up the slope of the hopper. The high frequency vibrator aerated the cement and made it flow easily thru the chute. PROBLEM: Flow of cement was erratic from silo and created a constant problem. SOLUTION: Model US-450 115 volt electric vibrator was installed on a 6” channel iron. A timer was also installed to start vibrator every 3 minutes to vibrate 20 seconds to keep flow going when cement was drawn from silo. Every...

ENGINEERING DATA \ CEMENT SILO Prevent Material Sticking to Bin Walls BRASOTA CONCRETE 3904 15th St. East Bradenton, FL 33506 PRODUCTS: Lindels and Specialty Blocks PROBLEM: Despite four aeration nozzles and a couple of old ball vibrators, the discharge of cement from the storage silo was very uneven sometimes non-existent. SOLUTION: One VIBCO Model ABS-2 Air Cannon was installed as shown in the photos, manually pushbutton operated from a control panel. With a few initial "blasts” a lot of "old cement” was cleaned out, and now cement flows on command every time. Air consumption has been cut...

SAND & GRAVEL Bins, Hoppers & Chutes A variety of vibrators are used for these bins and chutes. ELECTRIC, PNEUMATIC and HYDRAULIC. The selection depends on your particular circumstances please call VIBCO application engineers and we will help you make the best selection. First you must find out how much force is needed on the vibrator to move the material. Too small a vibrator will not do the job no matter if it is electric, pneumatic or hydraulic. Too big a vibrator can damage your bin. To find the correct force needed calculate the weight of material in the transition or sloping part of...

SOME ADDITIONAL CONSIDERATIONS: When sizing a vibrator to a bin: 1. If bin side angle is below 30 degrees select next larger vibrator. 2. If bin thickness is extra heavy or an excessive amount of stiffeners are present select next larger vibrator 3. On real sticky and hard to move materials it is better to use 2 smaller vibrators instead of one large one. Each one of the smaller vibrators will produce half of the force of one large one. 4.When using 2 vibrators it has been proven the best results have been obtained by using vibrators with different frequencies for example: In electric...

ENGINEERING DATA & APPLICATIONS SAND & GRAVEL 3 DIFFERENT WAYS TO MOUNT A VIBRATOR ON SAND BIN WITH HORIZONTAL STIFFENER Above Left: Stiffener not strong enough to withstand vibration. A 6” channel was added above stiffener. Above Right: Stiffeners were cut and a long 4” channel was welded on vertically. Left: Two 4” channel irons were butted up on each side of the stiffener. Vibrator mounting plate was welded to the top of channel irons and stiffener. ADDITIONAL APPLICATIONS: Right: Model 2P-800 on sand bin in cement block plant. Below Left: SVR 4000 high impact high frequency pneumatic...
