Stock round bar concaves work reasonable well in that they don’t plug often in good conditions, and therefore can be “universally” used across crops and conditions, but the rotor loss and grain damage in corn is unacceptable. There is more mechanical damage done to grain by round bars than anything else. Our patented RPR Concave System is the best of all worlds, no plugging, no rotor loss, less broken cobs, less fines, more capacity and significantly better sample from running a slower rotor speed.
The Estes RPR Concave System has addressed all of Thrashing-Separating Issues. Our patented round bar with a notch milled in it to restrict the crop flow and force material to rub on material, giving you a cleaner sample. Then the bars are placed progressively open to increase capacity and to ensure more crop is “unloaded” as it flows through the concave system. The flow was increased by 68%. This is all followed up by the placing of the 7 Disrupter lugs into your existing separating grates to finish the separation operation.
R | Restricted Flow Threshing forces more grain-on-grain threshing
P | Progressively Open to increase capacity so grain can be separate quickly
R | Round Bar with our patented notch gives a cleaner thresh yet still prevents plugging
THE MOST TRUSTED NAME
Don Estes invented the disruptor and tested six different sets in 1994 before going into commercial production on the product in 1995. The Disrupter pulverizes the corn shucks that would otherwise flow out the back of the combine, taking a lot of kernels with them. Farmers saw increased yields and Don sold more than 20,000 sets. Farmers were happy but wanted more so Don listened developing the Rotor Loss Kit which he released in 2010. The Rotor Loss Kit cut down on rotor loss by 33% but Don still wasn’t satisfied. He wanted a system that stopped 100% of rotor loss, increased capacity for the farmer and did less grain damage. Over the next several years, after hundreds of iterations and tens-of-thousands of engineering and testing hours, he developed the RPR System. The RPR Concaves system is now the best-selling concave system worldwide, having systems in Australia, South Africa, Italy, Denmark, and New Zealand, to just name a few.
The RPR Concaves System is the culmination of over 30 years of experience and testing. The product speaks for itself and with thousands of RPR Systems installed all around the world, there are many farmers that say the same.
