Conversions

The Vandergriff 181 Conversion for Continental Gin Stands.

The key to any successful conversion is an accurately drilled and tapped rib rail.  There is no one in the industry that can get this done as accurately as Vandergriff Inc.  My partner, Chris Nachtmann at CNC Performance Engineering for 19 years can hold tolerances from hole to hole at .001.  The machine can drill and tap the entire length of the rail, and we don't have to do it in pieces or segments.  The rail is stout.  Major troubles arise when rib rails are not machined properly on inferior equipment. Hole spacings have been taken directly from Mr. A.L. Vandergriff's drawings he did in 1996, when he converted a Continental Gin stand to 181 saws at the time.

Vandergriff Inc. has a proprietary arrangement on this arrangement used to  install the rib rail.  This fixture holds both end plates accurately and square allowing the rail to be put in perfectly. It all starts here with this type of precision, that will trickle down all the way to the space blocks and saws when its time to put that part of the conversion together. This is not done in a hap-hazard manner.

An accurately machined rib is a must for the narrowest saw spacing's in the industry. Cast Ribs will not be strong enough to hold up under the tremendous pressure that a 200 HP motor will exert. The lack of accuracy in the cast will also allow little variety's of seed slip through the gaps causing a nightmare for grades and loss of seed.  Vandergriff Ribs are accurate and machined from a 1018 domestic steel closed die forging. We don't use inferior material from China!  We have also tweaked the profile to allow for better seed discharge.  This also greatly contributes to increased capacity.

We machine our own end rib filler plates out of stainless steel, with a custom machined taper at the bottom that will accomodate the profile of the end rib.  This will provide a tight seal and eliminate many of the issues associated with sloppy end plate arrangements.

Game Changer Ribs

I wanted to give you some updates on our "Game Changer Rib." I don't think I have done a good enough job telling the ginning community how well these ribs are performing. We made a change to our Continental 161 rib two years ago, pulling the profile back down some. (See Pic)  This makes the slope of the rib greater and steeper which allows the seed to release or tumble out from the seed roll better.  If you are running a tight roll...this is going be of great benefit in releasing seed, making the roll run looser and ultimately increasing capacity.

The Rib in front is the new game changer profile. Note change from the older style in the back.

Customers running this rib in their 161 gin stands that previously ran very tight seed rolls are reporting up to a bale an hour increase per stand using the game changer.

This game changer rib is also a very important part of our 181 Game changer conversions when we convert 161-181 saw gin stands.  More saws, narrower spacings produce a denser seed roll.  These game changers are essential in helping get them out.  We have 181 Game Changer gin stands running 22 bales per hour here in the USA and in Australia as well.  

If you are interested in Game Changer Ribs or Conversions.  Call Vandergriff Inc.

Latest Update on Game Changer Conversion

Current Update on Game Changer Conversion.

This Sunday, October 26th, 2014 Ed Berry sent me the following picture. He was estatic that his 2 161 stands converted to 181 Game Changers were ginning 43 bales per hour. This is 21.5 bales per hour per stand.  Please read the previous blog and other blogs for more detailed information on these conversions. We are offering them for the 2015 season.

Do you have Continental Gin Stands?  Do you need more capacity and don't want to spend ridiculous amounts of money on new gin stands to get it? Give me a call. You will get fixed up and have lots of money left over to spend on other parts of your ginning operation.

The 181 Game Changer Conversion is a "Product of Vandergriff Research."

We run Vandergriff Gin Ribs and they are the BEST they run much longer with less tags and will be looking into doing the Vandergriff 161 conversion after this season when it gets on the market.

The Vandergriff 181 Game Changer Conversion.

"A Product of Vandergriff Research"

As most of you know, we have converted 2 Continental 161 Gin stands to a 180 saws and 181 Ribs.  This conversion took place at Moseley's Gin & Warehouse, Abbeville, Alabama.  Ed Berry is the gin manager there.  We now have some tangible results to report from these conversions. Our goal was to increase the capacity of the gin stand in the most cost efficient way, and to provide an option to the ginning community to increase their plant capacities without spending ridiculous amounts of money on new gin stands.  We have now proved that this can be done, by converting 161's to 181's.

What is the process?

For now, you can send us the middle part of your front where your rib rail is located, and we will remove it, and install a new rib rail accurately drilled and tapped with 181 holes. This will be a solid, stout rail that will handle increased loads.  We will make the space blocks and also provide end plates.  This conversion does not use end ribs.  We will also provide the "game changer" 181 ribs. We call this the game changer because of some profile modifications we made to the rib to let the seed out of the roll better, making an increase in capacity more achievable.  We will ship all this back and you just put your front back on get your saw stacked and trained using our space blocks, and then install the 181 ribs.  You will be ready to gin at higher capacities.  We recommend a 200 HP motor for maximum results.

First Reports on Conversion Performance.

161-181 Conversion

Two Continental 161 Gin Stands were converted by Vandergriff Inc. to 181 Gin Stands we are choosing to call "The Game Changer."  Very early on in this new season they have ginned 38 bales per hour on this two stand plant, meaning each stand is ginning at a rate of 19 bales per hour.  They are capable of ginning at even higher rates, but we will see if this plant can handle those type of capacities.  These conversions now are starting to meet our expectations, and we will begin to offer these to the ginning industry.  Please read other blogs here to see what we have done to these stands to get these types of capacities.

Vandergriff Inc. is the only company that can convert Continental Gin stands using the precision machining required to get optimum performance from these stands and of course along with narrower saw spacings,  the Vandergriff Game Changer 181 rib is an integral part of the conversion.

Updates. Let's Gin

Let's Gin!

Many of you have cranked up by now. Hope all is going well. Once again, we will be running two conversions in Alabama that will be of great interest if you have a Continental Gin Stand.  We have converted 2 - 161 saw gins to 180 saws.  This added amount of saws and ribs of course will allow "more ginning, " and will contribute to the seed roll having a greater density and running tighter. To off set this, we modified the profile of the rib to a little steeper slope to let the seed discharge easier. We know this modification works.  This rib (game changer) has run in Australia for 3 years now, and in a couple of gins in the USA this past season.  If you are interested in getting more capacity out of your Continental Gin Stands, we can help you, and do so in a very cost efficient manner.  We should have some good data on these conversions within a month, so check back here for updates.  You can get in touch with Loyd Vandergriff soon after if you are interested in discussing these conversions, and how they could help you.  Also, we are using this "game changer," profile on our new 161 rib.  They have performed well and helped customers ginning with 161's increase their capacities and keep those little seed from escaping though the ginning point and popping out behind the stand or worse, getting into the lint cleaners and getting ground up contaminating the samples. Ugh.

Remember, once gin season is over to get your orders in ASAP.  We make alot of ribs and wearplates, but it takes time and when we enter into a second run, this places delivery dates close to summer. It's much better to get your orders in and have them filled from our "first run."

We will provide precision end plates. There are NO end ribs in this conversion. But the contour of the end plate will fit snuggly over the last rib.  Again, note rib rail. Quality. Precision.
