With 10+ years of development, the R+ package combines the very best in engineering and innovative design to equip a typical “high speed” Peterson horizontal grinder into a “medium speed” machine, utilizing the production of a typical high speed grinder, and the protection of a slow-speed shredder. With performance nearly doubling the output of typical slow speed shredders, R+ equipped Peterson horizontal grinders offer a solution that has high output, and superior machine protection against ungrindable materials.
The R+ package uses a specially designed rotor with high and low bits, that turns at half the speed of our standard units. This processes material through a specialized heavy duty grate, with the high and low bits passing through the fingers, providing extensive fracturing surfaces for superior product reduction.
The R+ package utilizes Peterson’s patented Impact Release System, and Impact Cushion System to protect your investment against an ungrindable object, but has additional modifications such as a heavier duty cushion block to prevent nuisance openings, and an upgraded Impact Release System designed to perform in the harsher environment.
Other mods include more space for ground material to exit the machine, and a heavier duty discharge belt.
Already own a Peterson grinder? Your 4700, 5700, or 6700-series machine may be able to be upgraded as a package so you can take on the difficult jobs that you may have passed by before. Likewise, if you no longer need the protection of the R+ package, and your grinder is going into other applications, the R+ specific parts can be removed and replaced with standard units to change the machine back to a standard “high speed” grinder– no other machine on the market can do that!
Decreases the operating speed, and increases the horsepower. Allows the rotor to sustain less damage with each impact and improving bit wear by 100%. Increased Drive to Driven sheave ratio creates more torque to efficiently power through heavy impacts.
The asymmetrical pattern combined with alternating HIGH/LOW bits creates a much more aggressive and uniform exposure to the contaminated material being processed.
The comb grate is set in the #1 position and the 3’’ cutouts add to the “comb” feature, increasing the cutting surface of each low bit. Allows the rotor more opportunity to process contaminated material.
This baffle sees the full force of all material ejected from the rotor because of it’s placement in the #2 position of the grate supports. The standard ¾’’ steel plate has been strengthened with an additional supporting piece of ¾’’ hardened, Grade 80 steel, for heavier impacts.
Increased thickness of discharge belt to ½’’ provides longer wear life compared to the standard (3/8’’). Overall tinsel strength of 440PIW is double the standard to create a more puncture resistant surface for heavily ejected material.
Facilitates a heavier loading of the belt and allows the system to carry away a larger sized material more efficiently. Dashed line indicates standard conveyor clearance; Red line indicates improved R+ conveyor clearance
Increased durometer allows the Impact Release System to absorb a harder hit without releasing.
