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.

Rumors and misinformation about Vandergriff Ribs that run in gin stands with narrower saw spacings are proving costly for those that took the bait.


"We were told your rib lost seed."

Mid Summer 2017

Summer is flying by.  We have been rocked by brutal heat in the Central Valley of California.  This has caused what was already an abnormal amount of snow in the high Sierra's to melt at a higher rate and rush down rivers and streams into reservoirs that simply can not handle this volume.  The only alternative was to "let it out," into the streams below. This of course has caused flooding down below in many areas.  Fortunately, the fertile Tulare Lake bottom has survived.  There were many bleak scenarios related to this, some as bad as 1969 that actually made the cover of Time Magazine.  But now, huge acreage of cotton will be planted, the biggest crop in years.  The entire cotton crop around the central valley looks as good as I have seen in many years.



The 1969 Flood was so serious that old cars were hauled in to place along the levee's to prevent erosion that could lead to serious compromise. A picture similar to this made the cover of Time Magazine.

1968 El Rico Gin

J.G Boswell's El Rico Gin had to be completely dismantled and hauled into the town of Corcoran and stored until the threat of the flood was over. Then, rebuilt.
This gin had many first for the industry.

World's First 40 BPH Gin plant.
First to have bales strapped naked at press.
First to have Automatic Trailer dump
First 10 foot cleaning equipment.
First drying systems to handle these types of capacities.
Design Engineer. A. L Vandergriff

We are glad the that things did not reach this level of seriousness with the heavy snowpack of 2017. This will allow companies like J.G. Boswell and other central valley farmers to plant as much cotton acreage as they like. Good news indeed.  

More news:

Vandergriff Inc has several projects going now that give cause for some excitement as the gin season approaches. On the gin rib front, we were thrilled we could help out a couple of gins that had ordered and  received new gin ribs that were not straight, making it all but impossible to even get them installed.  We happened to have enough in our inventory to supply them and solve this issue for them. You all know that Vandergriff Ribs will never show up to a gin with issues related to straightness.  We have pretty much sold out of all models of our ribs now.  That's usually the case when it gets to be this time of the year.

We got many of our Jet Dryers in some nice gin plants this spring and summer as well. In an environment where energy costs are a real factor, these dryers are extremely efficient to operate.  Lots of natural single locking action going on in the dryer that prepares the cotton to do a better job of releasing trash when it hits the incline cylinder cleaners.  More and more ginner's are seeing the benefit of switching over to Jet Dryers to dry and condition their cotton while saving money on energy costs as well.

We hope as gin season fast approaches, that it will be a good season for everyone.  Don't hesitate to give us a call.

More Gin Rib Updates.

There continues to be discussions and debate on design of gin ribs, especially when it comes to relief sections for ribs running in stands with narrower saw spacings,  I will again emphasize that Vandergriff came up with the current spacings in 1996.  Along with this, he developed a rib to go with it.  In doing so, he chose not to abandon the type of relief section that he had used in all ribs Vandergriff Inc. had manufactured up to this time.  The Vandergriff Rib was already well on its way to becoming the standard in the industry. This relief section, coupled with the skilled use of CNC Machining from a 1018 steel forging contributed heavily to the success and performance  and reputation of Vandergriff Ribs.

There continues to be emphasis by some that this relief section needs to be narrowed, or closed up more to deal with seed loss. This argument is presented by competitors that have had serious issues in this area.  We have not had these issues with the Vandergriff  Rib and see no need to change our current arrangement.  Please take note of the following.


Vandergriff 181 Gin Rib for Continental Gin Stand


This Gin Rib is used on the 161-181 saw spacings established by Vandergriff in 1996. We worked with Namoi Cooperative in converting their 161-181 saw gins. Ultimately they ended up with 20 converted gin stands, all running the Vandergriff Game Changer rib with our standard relief section.  They are not losing any seed with our design. Overall, there are a total of 26 gin stands overseas and in the USA  with narrow saw spacing's running the game changer with this relief design. None. Zero, report any seed loss.

Given this type of success,  it was only natural that we apply this same relief design to our Vandergriff  Rib for Consolidated 184/222 saw gin stands. These stands use the same narrow saw spacing's as the Continental 181. (Vandergriff, 1996 spacings)

Given all the talk through-out the industry related to this, I decided to make some inquiries on how our Ribs are currently performing this season.

Chris Veness at Southern Ginning in Australia is running our rib in all 4- 222 saw gin stands in one of his plants.  When I enquired how the ribs are performing he said: "The new seed varieties make it more difficult to clean the seed, so we are having to gin at a slightly lower ginning rate, but we are not seeing an issue with seed loss." We continue to be very happy with the ribs, and all 4 gin stands run non-stop."

I called Jackson Hammack at Early Country Gin in Georgia.  He has two of his three 184 gin stands running our rib. He said, "We have no issues with the Vandergriff  Rib. We certainly have no issue with seed loss.  We push these stands up to 20 bales per hour plus and they just gin.  We most certainly can not do this with our other gin stand that is running conventional gin ribs.

All Vandergriff Ribs use this Vandy Relief design.  This, coupled with precision CNC work from 1018 steel forgings allow ours to perform at high levels. From Lummus 158-170. To Continental 141-161-181. We have them running in Cherokee Stands as well. Their performance in all these stands over time has helped establish the rib as the premier rib in the industry.  But even with this well earned reputation, there can be exceptions to the rule when it comes to performance.  These exceptions are difficult to understand or explain. It could be as simple as the ginning point being off, tooth lead not in proper location, or the rib rails themselves not located or installed accurately.  Other gin stand issues and settings could come into play.  I would only comment from a Vandergriff perspective that any issues such as seed loss and performance are extremely rare with our rib and most often  caused by issues that are not rib related.
