The premier equipment line of Jordan Reduction Solutions is our Hog Mill Industrial Grinders. No other grinder on the market has the versatility of application and ruggedness of design as do these reliable and dependable units. Many installations of these grinders are still in operation after over 50 years from original start up and continue to perform at an exceptional capacity. Suited for both wet and dry grinding applications, the JRS Hog Mill Grinder is the perfect choice when demands are somewhat complex in nature. These units continue to serve in applications from organics grinding, rubber grinding and even into ordinance and energetic material (explosive) applications.
With a unique feed system, the Jordan Reduction Solutions Rubber Grinder has been servicing the rubber industry for decades. Our specialized rubber bale feeder, located in the throat of the unit can take whole rubber bales and reduce them to as small 1/4 or below with out without a screen assist (material dependent). Additionally, the rubber bale design reduces the amount of recycle time in the chamber giving greater through-put with minimal horsepower requirements. These grinders also integrate either the ability for a fluid or dry powder partioning agent to enhance the grinding operation and help prevent agglomeration of the ground product.
Designed for high-speed and high-inertia operation, these industrial grinders can power through multiple materials with significantly lower required running horse power ratings yielding and higher production capacities at lower operational costs. Rotors are cast in carbon steel or stainless steel, depending on the application requirements and are a closed-rotor design which is ideal for reducing large heavy infeed materials down to a particle size of 1/8 to 3/8.
We stock a complete inventory of our OEM Hog Knives, knife clamps, and high-strength bolts. Additional replacements parts include throat bars, throat plates, and most screen. We also offer on-site or in-house service and maintenance on all JRS machine and installation of our replacement parts.Learn more about our Parts and Service Department.Please have your machine model number and serial number when calling or inquiring about replacement parts.

The Rubber Chopper reduces bales of synthetic and natural rubber to small particles through a combination of low speed and high torque. The resulting particle size ranges between 0.5-1 inch (1.2-2.5 cm) which expedites dissolution prior to blending and compounding. Low-speed operation keeps product temperatures low, preventing melting prior to dissolution and excessive wear, as can often be seen in high-speed grinding applications.
Rubber or polymer bales enter the feed hopper, typically by gravity from a feed conveyor. Slow rotating claw-like hammers cut into the bales, shearing them into smaller chunks. Internal adjustable anvils, or resistor bars, provide internal resistance to better control energy input which determines heat input and final particle size. The ground material continues forward to the discharge where it is forced through an orifice plate. Upon exiting, the extruded rubber is sheared by the cutoff knife assembly, producing a consistently sized granule, or crumb size. This rubber crumb often discharges by gravity directly into a dissolution tank.
Depending on the material being processed, or the downstream operations, Bepex has provided dosing equipment to meter in anti-sticking agents such as talc either in the grinding chamber or at the discharge. A specially designed hydraulic ram feeder may sometimes be necessary to force-feed bales into the grinding rotor.
The Rubber Chopper bale grinder is just one of the size reduction technologies we employ to develop industrial process systems that meet your application requirements. At Bepex, we are committed to developing the best size reduction process systems using the right technology. Between our proven industrial process equipment and decades of experience serving the industry, we are able to design a grinding solution that is right for you.

Tire grinding for recycling was first developed in Minnesota in 1985. It began as a mechanical process to break down the tires and separate the useable rubber from the metal and fabric components of the tire. Similar to the way an office paper shredder destroys documents, these shredders cut the rubber into smaller pieces. By weight, a typical tire is 70% recoverable rubber. The rest is steel, fibers, and fillers. When recycled, a standard passenger tire will yield 10-12 pounds of rubber after filtering out the other materials.
Regardless of the final method used, all three primary grinding processes start the same way. Mechanical, ambient temperature grinding is the only method that can take a full-size tire and break it down into smaller pieces that can be fed into other machinery for further processing. After this initial break down step, there are three primary grinding methods that tire recyclers use.
Each grinding method requires different equipment and materials and produces a slightly different product, giving each advantages and disadvantages. The process that is best to use is the one that will provide the product that the customer wants. In many cases, contractors may not care as much about the type of rubber that they are buying as they do about its cost.
When rubber is ground at ambient temperatures, it still maintains the characteristics of rubber. Being somewhat pliable as it passes through the shredders, the edges of the cuts are rough. These rough edges affect the properties of the rubber. For example, for use in Rubber Modified Asphalt, ambient cut crumb rubber is preferred. The rugged edges of the rubber crumb give it more surface area to bond to the asphalt with which it is mixed.
When using the cryogenic process, recyclers spray the rubber or submerge it in liquid nitrogen. At temperatures below -112F, the rubber no longer acts like rubber. It acts more like glass. When hit in the hammer mill, the rubber shatters along smooth, straight lines.
These smooth particles that appear shiny are less prone to hold air bubbles when submerged in water. These particles are also better for mixing with sand as infill. They form a more stable connection and foundation with the silica sand. For this reason, cryogenically ground rubber is preferable for use in athletic fields. When rain falls on the artificial turf, ambient ground rubber has a tendency to float and move around in the water. This movement can create an uneven playing surface that may even contain potholes, creating a dangerous situation for players using the field.
Cryogenic grinding comes at a cost, however. Liquid nitrogen, while common and easily attainable, can cost a recycling company 2 to 6 cents per pound of rubber, depending on the desired rubber particle size and the quantity purchased.
With the many varied uses of rubber crumb, it is clear that no one grinding method is best for every situation. For many companies and applications, the best product will be the one that is the cleanest, highest quality rubber that fits in the project budget. There are not currently industry standards governing rubber crumb quality. However, there are the key components to look at when determining the best crumb rubber for any job. Rubber with low metal, fiber and moisture content is best.
At EcoGreen Equipment, we offer tire shredding equipment that can grind rubber to all different sizes and specifications to help you produce the best product. From our Eco Green Giant that produces 2 to 6 inch shreds to our Eco Krumbuster, which can produce rubber crumb or powder smaller than 850 microns that is 99.9% free of wires and fibers, we have your needs covered.
