Hope ginning season is going well for you.
We are not hearing much about little seed being an issue in the USA here this ginning season yet. At least not as far as Vandy Inc is concerned.

Know we make ribs for all models of gin stands. This includes Cherokee stands.  No one can duplicate the way we produce them from a forging to a final CNC machined part from 1018 USA Steel.  Some of our customers have been running the same set of ribs for well over 10 years.  This is pretty cost effective.

Most know we are the pioneer in gin stand conversions. Mr. Vandergriff converted a Continental 161 to a 181 in 1996.  This went largely ignored until the mid 2000's.  Now this saw spacing is becoming the standard.  He set the standard for saw spacings many times over his illustrious career., and the rest of the industry tagged along. We have lots of conversions running around the world particularly in Australia.

This link below is a Lummus 170, souped up by Vandy Inc and associates. It is the first one we have done, and after working through some issues, we have it down if ya want to increase capacity without having to lay down huge chunks of money.  This would include of course  new gin stands (they love to sell you those) over-head, and even more. $$$$$$ (lint cleaning, press)  Conversions are the cost effective way to increase capacity.  They come with Vandergriff precision and the Vandy Gin Rib.

Vandy Inc and Vandergriff American also sell the Jet Dryer.  Its starting to speak for itself with how it reduces moisture in a very cost effective way.  Gets the cotton single locked and ready to enter the inclines warm setting the stage for more trash release.  Mr. Vandergriff always said, get that cotton into the inclines at 175 degrees. Why? Simple. Get better trash release and cleaning.

Our Spider Installations are taking off as well across the cotton belt.

If you have any questions, don't hesitate to call.

External Factors that Affect Cotton Ginners


For at least the last 50 years, many things have come down the pike that have in one way or another affected cotton ginners and the operation of the gin.   I use the word "external" in the title because ginners and gin plant owners usually are involved very little in the discussions regarding these changes, but of course they are heavily involved modifying their gins to accommodate them. By now, I think many of you are getting the drift of this, so I won't go into specific details regarding these types of situations that have come the gins way over the years. I have often wondered just how much "gin people" have been brought into this loop when these types of things start to get discussed. Maybe there are some committees or some "superficial" attempts to get ginner input, but one has to wonder just how well is the ginning side of the equation really represented?  I have seen some bad scenarios come the gins way that led to very costly modifications.  I doubt that the cost was shared in any way, and it fell squarely on the owner or owners of the gin.

Today, there is much R&D and competition among big cotton seed breeders to get seed to the grower and farmer that will significantly increase yield of cotton per acre. We all know who the big players in this game are.  While R&D on this side of the equation has done, and continues to do  much good, it would not be beneficial to have this research backfire on the other side of the equation and cause the gins difficulty. In order to obtain these types of increased per acre yields, in many cases the seed  have become smaller and smaller.   When these small seed cannot be extracted from the fiber at the gin stand, they  pass on through to the lint cleaners.  Here, they are ground up and mixed into the lint.  This will affect the grade of this fiber in a very negative way. This of course will not be well received by the farmer who wants and expects the best grades possible from the gin. It is important to know that some ginning operations are starting to show concern over these little seed, and their ability to gin it.

Gins that use products of Vandergriff Research, more specifically The Vandergriff Gin rib, have a great deal of success in removing the seed from the fiber during the ginning process.  The seed is extracted, cleaned thoroughly and then heads on down the line where it is supposed to go.  Over a 21 year period, Vandergriff Ribs have established a sterling reputation in terms of overall  performance in the gin stand, and preventing the loss of seed of all seed varieties.  We want the ginning industry to know that we are closely monitoring this situation related to these new varieties of seed, and will respond to it in  regions most affected, should this continue to be a problem.   It is important to note and understand, that is possible for the seed to get too small to effectively remove it  by any means from the cotton. Hopefully the ginning industry will have a dialogue with seed breeders about this important issue and monitor it closely, just as we are. The ginning industry is to be commended for the way it has responded to all the challenges that have come its way over the years and will continue to try and meet all new challenges that come its way in the future. We are proud to be a part of that.

Ribs and Miscellaneous

Ginning season is right on us, and some of you have already started, especially in South Texas.  Some of the crops may come in earlier than expected in the southern states as well.  Vandergriff Inc is already running ribs for export right now.  We have big orders to fill.  As soon as we complete this run, we will jump right in to making ribs for the USA market.  Most of you know that to make a Vandergriff Rib is very time-consuming.  From forgings we acquire (From 1018 USA steel) to CNC Machining each rib.  This is why its important to get your orders in as soon as possible. Even now  is not too early for the USA market.  When we order forgings, we can include your order and you will get yours in early spring.  Orders placed right after the first of the new year also have a good chance of delivery in early to mid-spring as well.  We now manufacture several models of ribs for different type of gin stands and this adds to time of production.  If we were running one particular model of rib, we could just let it roll.

We make ribs for:

Consolidated Gin Stands
Lummus Gin Stands
Cherokee Gin Stands
Continental Gin Stands

Our ribs are made in the USA.  Our competitors are for the most part, made in China, India or Pakistan.  There is no comparison in performance. Don't let your huge investment in a gin stand have its performance affected by inferior gin ribs.

We have a lot of our Jet Dryer installations running this season, along with many others that have been running for many years now. Cost effective drying.  I have written other blogs on this. Check them out.

We have a couple of other products hitting the ginning market soon.  Keep your ears to the ground and check here every so often. You will be hearing about them. :)

Ribs, Misc


Consolidated 164 Gin Stand

"A Product of Vandergriff Research"

These Consolidated Stands are "Built Tough." There are still a lot of them on the market ginning.  Not only 164's but 198's and 116's.  Our rib can most certainly can help this stand, and has helped it.
Don't tolerate ribs that are not straight, that tag and cause rib fires.  That misery alone will quickly pay for a set of Vandergriff Ribs.  Ours are CNC machined from 1018 steel.  Accurate. Straight. Vandergriff design.  Proven.  Purchase ours and let that stand gin. Worry about other issues in your gin plant.  We also have Vandy Ribs for their 184 and 222 saw models.  They have run. They have ginned. They are proven.  If you want some Vandy ribs get on the list ASAP. It is never too early to call.  This is the same for all models of our ribs. It is never too early to call and get on the list.

We hope your season gets off to a great start.  Gin that cotton! Hope to see you down the road.

Late Summer Updates

Cotton is planted, and on a still night if you listen close enough, You can hear it growing.


Does this dryer look familar?


Continental Gin Company Counterflow Dryer 1950's
Note Cylinders at Bottom.

There seems to be a renaissance for this type of dryer, followed by large amounts of cylinder cleaner arrangements. This is a little history of this type of drying and why it ultimately faded. This information is taken from "Ginning Cotton, An Entrepreneur's Story," By A.L. Vandergriff. Pages 209-210.

Continental Introduced a counterflow dryer in the 1950's. It  was a unit consisting of a vertical box with spiked cylinders mounted inside in a vertical row, along the centerline of the box or chamber.  Adjacent to the cylinders on each side were long metal strips mounted on the wall of the box, spaced so that air could flow between them.  The cotton entered to top of the box by gravity onto the first cylinder, which knocked it onto the metal strips. These metal strips were sloped downward so the cotton could slide down them to the next cylinder. This process was repeated from one cylinder to the next. I believe there were four of these cylinders in the stack. Heated air entered the bottom of the box and traveled upward against the flow of cotton, thus the name counterflow.  Once I began increasing the capacity of the plants, it became necessary to split the flow and in doing this I added Tower Dryers, placing the counterflow dryers in series and following the Towers. This was done to primarily make use of the three cylinder cleaner under the counterflow dryers.  Currently, it is important to note deficiencies with the counterflow concept here and why and actual dryer had to be added prior to.  These dryers were never efficient. The fiber to fiber exposure to heated air was not as good as that in the Tower Dryers.  It seems that none of the drying efforts that tumbled cotton in bulk were efficient.  

We at Vandergriff American like to expose the cotton to drying and conditioning before getting into any type of cylinder arrangement, and we like to keep fiber exposure to any mechanical action (cylinders) to a minimum.  The action in our Jet Dryer requires no cylinders or any type of mechanical action. We create what we call a natural dynamic.  The cotton is conveyed to the top of the dryer in a  single stream and hits the top of our Jet, which is cylindrical. It then fans out in a 360 degree arc and begins its descent down the sides engaging the upspream flow of cotton. This dynamic creates turbulence and a swirling action that begins to single lock the fibers to allow warm air to flow through, and trash to begin to separate out.  It then exits out to the inclines or cylinder arrangement most gins currently have.  We get a nice even flow and even bat that allows the cotton to spread nicely across all the cylinders.  There is no need to add a horizontal cleaner arrangment with this. You can use what you have. If you are installing Jets in a new plant, the horizontal cleaner will work fine if this is the route you choose to go. There is mimium static drop with our system compared to a large number of cylinders that the cotton would be exposed to with a counter-flow/vertical flow type system. Remember, these systems start the drying process with cylinders involved.  All are in agreement that it is not desirable from a fiber quality point of view to let cotton be exposed to lots of cylinder's and too much aggressive mechanical action to dry and clean. Also note that with these counter/flow, vertical flow type "dryers," followed by a large number of cylinders, there is a real danger of roping and trash being embedded if this 1950's approach does not get the moisture content of the cotton down enough prior to entering the cylinders. Big risk here.  How much do you want to "slow down," on wet cotton to keep fiber quality up?  Our Jet's will work with your existing 8', 10' and even 12" cleaners in both stages of your operation. So, what you get with our system is a good drying dynamic without excessive cylinder exposure. It preps and conditions the cotton nicely and allows your existing cylinder cleaner arrangement to work more efficiently in terms of fine trash removal.  

"Don't let your cotton fiber be exposed to an excessive amount of cylinders, and then be run through 2 stages of "Shredders," (lint cleaners) before getting to the press.  The Fiber and the mills will appreciate you.

Ginning Season on the Horizon


We hope the repair season has gone well. It was another good year for Vandergriff Gin Ribs, we appreciate all our loyal customers, and those that have installed our rib for the first time. You won't be disappointed.  Gin ribs are what we do and take pride in, from 1018 USA Steel that are forged into an accurate forging by a process that is hard to duplicate, and finally to the extreme precision of our CNC Machining.  And it is this precision in key areas that makes all the difference. We have been doing this for 21 years now and have the formula down especially in vital areas of the rib design. If smaller seed are becoming a consistent issue for you, we can take our existing design that is proven over time and slightly modify it to what we call for now, a Vandergriff "Extreme." This will most certainly deal with littler seed varieties.  If you are running even narrower saw spacings, our design will run smoother, not damage seed or cause rib fires, and you will not have to pull out the stand to blow out or clean ribs on a frequent basis.

There was some very bad information that spread through the industry about the need for a good rib for gin stands with narrower saw spacings. Our rib, unfairly got lumped into the category.  The source of all this did have huge issues with  ribs, but had never tried a Vandergriff Rib in their gin stand to try and remedy this issue. Statements like this are unfortunate for the industry.  Our rib for  gin stands that went to narrower saw spacings (Vandergriff 1996)  have been running and are running in  gin stands across the cotton belt and in Australia as well. Vandergriff Research was and is the catalyst behind the industry's move to narrow. We developed gin ribs to accommodate this. It is inconceivable that with so many of them running successfully in the industry (8,000+) that they would lose seed.  Again, if small seed are becoming troublesome, we can apply our Extreme design feature for you.

If you currently  ginning with Consolidated Gin Stands, we can help you.  164. 198. 184. 222.  We have ribs for you. They run good. They don't tag or start rib fires. You don't have to pull out the stands and clean them out.  Don't let gin ribs hamper the performance of your Consolidated Gin Stand.  It is a very good, well designed piece of ginning equipment. (A Product of Vandergriff Research)

Our Game Changer Ribs for Continental Gin stands are the Cadillac of Ribs for your Continental  gin stand.  Competitors talk a good game, but we always get calls and end up replacing them with ours.  Tagging, Fires. Breakage.  Just things you should not have to put up with from gin ribs.

We of course also provide Vandy ribs for Lummus 158, 170 and other model gin stands. Same Vandergriff Design and production process that has made it the Cadillac of ribs for 21 years. Many of these have been running in gin stands for 10 years or longer.  They simply change out the wearplate when necessary. The accuracy, strength and precision of this model rib has ruled the day since its inception.

Cherokee Gin Stand Owners?  We have Vandy Ribs Running in your stands as well. We can provide help for you too.  If you are going to wider gin stands up to 12 feet and have extreme horsepower on your roll box. You need a Vandergriff Rib to deal with these difficult stresses and strains put on the gin rib.   Don't let inferior ribs hamper performance of your gin stand. You have way too big of an investment for this to happen.

The Jet Dryer is also a product of Vandergriff Research and ginners are finding all about its unique drying features, energy efficiency and cost savings.  Not to mention good drying that continues on into the cylinder cleaners promoting more efficient trash release.
