Line Vac Makes Golf Ball Testing More Efficient

Recently, we at EXAIR worked with a major player in the golf ball manufacturing world.  As an avid golfer myself, this was an application I could really get a ‘grip’ on and I had the ‘drive’ to propose a solution.

The customer was involved in Research & Development, performing testing on the golf balls through robotic hitting, collection, and attribute measurement. The current set up involved the ball being hit, gravity collection into a PVC tube, and then an operator unhooking the tube, walking it over to and unloading the balls onto a rack, in the same order of hitting. The customer wanted to eliminate the manual task of the tube handling and have the balls delivered directly to the rack area.  The transfer would need to be 15′ vertically, then 15′ horizontally, before dropping down to table level.  A typical rate is only 5 balls per minute. This is a perfect application for the Line Vac, a compressed air operated conveyor.

EXAIR had previously tested golf ball conveyance, as seen in the Line Vac video below (at the 1:53 mark) where golf balls are conveyed 100′, at only 30 PSIG of supply pressure.

To present the best solution to customer, we had 2 dozen golf balls sent to us, and we set-up and simulated the actual conveyance conditions of 15′ vertical and 15′ horizontal travel. We found that the balls could be conveyed at only 20 PSIG of supply pressure, when presented one at a time. When the inlet was flooded with golf balls, simulating a worst case condition, the Line Vac was able to perform the conveyance at 60 PSIG. Operation at 80-100 PSIG is possible providing a operational safety factor.

The customer was impressed with the results and has implemented the model 6984 – 2″ Aluminum Line Vac Kit into the process, making the process more efficient.

Light Duty Line Vac For Paper Trim Removal

Today I worked with a customer that manufactures a wide variety of material handling equipment including coil unwinders.  The engineer was calling because there was a special project for a coil unwinder that could handle a waste piece of paper trim.  As the metal coil is being unwound for delivery to a metal processing machine, the protective paper is pulled off and was to be collected into a waste receptacle for easy handling and disposal/recycling.  The engineer was hoping to replicate an existing system that used a hybrid blower system, with an extra compressed air nozzle, but in a simpler form.

Coil Unwinder

We proposed the use of the 4″ Light Duty Line Vac– shown below.130400The Light Duty Line Vacs offer an effective way to convey small and light materials a short distance. Like the standard Line Vac, the Light Duty Line Vac converts an ordinary hose or tube into a  conveyor for scrap, trim, and bulk materials.

When the process involves moving low volumes of materials over short distances, the Light Duty Line Vac is a great choice. The simplified (2) piece design offers effective conveying at a lower cost. As an added plus, the compressed air consumption is lowered to levels commensurate with handling the lighter materials, at lower volumes and short distances.  Using a pressure regulator to control the supply air allows for tuning of the transfer rate, and keeps air usage to the minimum amount needed.

The Light Duty Line Vacs are available with inlet/outlet diameters from 3/4″ up to 6″.  With no moving parts, maintenance free operation is assured.

Threaded Line Vacs: Low Cost Conveyor Uses Ordinary Pipe!

EXAIR’s Threaded Line Vac air operated conveyor takes an ordinary pipe and converts it into a powerful conveying system.  A fast, low cost way to convey items such as pellets, scrap trim, bulk solids, chips, paper, small parts, sawdust, granules, and so much more. The Threaded Line Vac attached easily to plumbing pipe couplers, like PVC or iron, making it easy to build a complete system with parts readily available from your local supply house or hardware store.

The Threaded Line Vac are ideally suited for conveying large volumes of materials over long distances.  Like the standard, smooth bore ended Line Vacs, the unit works by ejecting a small amount of compressed air to produce a vacuum suction on the inlet side and a high output flow from the outlet side.  By using a pressure regulator to control the compressed air supply pressure, the rate of conveyance can be controlled to match the application needs, while minimizing the compressed air usage.

3inTrLVbckls_prHR1670x574

Models are available from 3/8 NPT to 3 NPT with materials of construction of aluminum and types 313 and 316 stainless steels (excellent corrosion resistance.)  High temperature versions of the stainless steel Threaded Line Vacs are available as well, for temperatures up to 900°F.

For those processes requiring the highest rates of conveyance over the longest distances and/or the most abrasive of materials, the Heavy Duty Threaded Line Vac is the right choice.  Designed with the most rugged industrial processes and applications in mind, the special hardened alloy construction helps prevent premature wear that could occur with standard aluminum or stainless steel models, under the harshest of conditions.  The performance has been boosted, to be able to convey more material, over longer distances and higher vertical rises.

To select the right model, information regarding these criteria is helpful-

  • Size of parts and bulk density of material being conveyed
  • What size hose, tube, or pipe is desired
  • Target conveyance rate
  • Distance of conveyance, both horizontal and vertical legs
  • Preferred material of construction

For another look, please see the video available that provides more details about the Line Vac family.

Line Vac Alleviates Back Breaking Work in Drying Cocoa Beans

An overseas plant had a large operation processing cocoa beans.  They would pick the pods off the cocoa trees, remove the beans from the pod, and place them on a large screened table to dry in the sun.  The drying process may seem primitive, but with the natural energy of the sun, it is free.  To completely remove the moisture from the cocoa beans, they would have to keep the beans exposed to the sun for close to a week.  As a daily operation, the workers would have to carry beans to and from a storage container by shovel and bucket.  In the morning when the sun was rising, they would shovel the beans from the storage container and spread them onto the table.  Before evening came, they would shovel the beans from the table back into the storage containers.  This back and forth was very hard work and time consuming.

In discussing their setup, the storage containers were a maximum of 10 meters away from the drying tables.  The bulk density of cocoa beans are roughly 980 kg/m^3.  So, with 19L buckets used to carry the beans, each one would weigh a bit over 18Kg each.  The operators would carry two buckets, multiple times during the day to load the tables (reference the photo below).  Then they would remove the beans in the evening to put them back into the storage containers.  The reason that they had to store the cocoa beans at night was because of dew.  When the temperature drops during the night, dew would settle onto the beans and rehydrate them.  So, to keep the beans drying at a moderate rate, they had to store them during the night.  This was very hard work on the workers’ backs, and they were also losing sunlight hours as this was a long tedious operation.  In trying to find a better solution to improve their operation, they searched and found the EXAIR Air Operated Conveyors.

The EXAIR Line Vac fit very well into their operation. I suggested the model 152200 Heavy Duty Line Vac Kit as this unit has our highest conveyance rate.  It can convey the cocoa beans at a rate of nearly 900kg/hr.  It is very compact and easy to use.  This plantation placed a 10 meter length of hose in between the storage containers and the drying tables.  They attached a 1 meter section of hose to the vacuum end of the Heavy Duty Line Vac.  Because the Line Vac pushes the product much better than it pulls, we recommend the vacuum hose to be 1 meter or less for optimum conveyance.  So, in the morning, they would go to the storage container and attach the 10 meter hose to the exhaust end of the Line Vac.  They would open the compressed air line to the Line Vac and watch the cocoa beans being conveyed to the drying tables.  In the evening, they would reverse the procedure and attach the Line Vac to the 10 meter hose near the drying tables.  They would watch the beans being conveyed back into the storage containers.  Not only did this save the backs of their workers, it also increased the amount of drying time.  With their new operation, the cocoa beans now had an additional 1 hour of drying each day in the sun.  This helped tremendously in getting the dried cocoa beans to the processing factory more quickly.

Air Operated Conveyor Provides Solution for Glue Pellet Transfer

As companies move to other facilities or are expanding inside their own, sometimes you have to get creative with your system. In this situation, a paper facility had to move their glue line to make room for another project. The system included a transfer module for moving hot melt pellets from a storage bin into a hopper where it was heated and applied.   In the move, they could not locate the transfer module close enough to the glue line for safety reasons. They contacted EXAIR to see if we could help.

In discussing their layout, the best location would be to place the transfer module on the other side of an office pod but the transfer module could not move the hot melt pellets that distance. They needed to move the hot melt pellets about 20 feet horizontally and about 6 feet vertically to reach their glue line hopper, something an EXAIR Line Vac can accomplish. We decided to use a model 6083 1 ½” Aluminum Line Vac to help out. The conveyance rate would keep up with the transfer module, and it had enough power. The pellets would be transferred to a nearby bin by the module. Then the Line Vac would move it from the bin, over the office pod, and into the hopper on the other side.   With the transfer module out of the way and the hot melt pellets still feeding the glue line, they were able to continue operating the system.

Twin Line Vac Solution For Transferring Alumina Desiccant

LV feeding tank 2
The tank on the right needs to be filled and drained of alumina desiccant

The sketch above shows a 115” tall tank which needs to be filled and emptied multiple times with activated alumina desiccant.  The desiccant ranges in size from 1/8” to ¼” with a median size of 5/32”, and has a bulk density of 48 pounds/ft³.  The material has no fire or spill hazards, and poses a low health risk.  (We evaluate these characteristics with every application to ensure the Line Vac is a viable solution.)  The end user wanted to find a solution to move the alumina into the tank, and then a method to move it out of the tank.  Total material transfer could be as high as 1500 pounds/hour.

Originally, the end user considered the setup shown below.  This setup would empty the tank through the top, and then use the same Line Vac to refill.

Original transfer solution

What the end user and I came to realize, is that we could achieve full automation in emptying the tank by using a dedicated Line Vac with a slide gate.  And, another dedicated Line Vac could be used to fill the tank, preventing any toggling of the Line Vac orientation. This was the solution, one Line Vac on the desiccant fill port and one Line Vac on the desiccant empty port.

Because of the high conveyance rate and the requirement for a material which could withstand abrasives, model 150200, our 2″ Heavy Duty Line Vac made of a hardened alloy, was recommended.

Ionizing Point Best Thing for Static on Trim Scrap in Cyclone Separator

This application came in from our distributor (AYRFUL) in Argentina. They had a customer who is recycling film scraps. The scrap material is conveyed into a cyclone separator. The problem is that the scrap becomes charged with static as a result of the motions and interactions within the conveying pipe. This results in the scrap sticking to itself and to the parts of the cyclone separator inside. The problem is so bad that it becomes almost impossible to separate the material when it comes time to clear it out of the cyclone separator once clogged.

After discussing the challenges the customer faced in trying to keep their cyclone up and running, we decided to recommend that the customer utilize 4 pieces of EXAIR’s Model 7199 Ionizing Point and 1 piece of Model 7941 (4 outlet Power Supply) to neutralize the static within the cyclone.

The ionizing Points would be attached by means of inserting through the wall of the inlet pipe of the cyclone separator.

The existing blower moving air into the cyclone separator will do the job of carrying the positive and negative ions into the cyclone separator and keep it and the contents at a neutral state.

If you have a similar problem, contact us to discuss the application. We would be glad to help with our full range of static eliminators to address your application issues.
