The 300 degree swing radius of the unloading auger allows repositioning of the discharge auger from one side of the machine to the other without moving the grinder-mixer.
Mixing Auger
![H&S Manufacturing GM 170 Grinder-Mixer](http://www.donallisonequipment.com/HS-Manufacturing/Grinder-Mixer/6.jpg)
A 14" mixing auger with a 30" base provides superior mixing uniformity.
Slide Door
![H&S Manufacturing GM 170 Grinder-Mixer](http://www.donallisonequipment.com/HS-Manufacturing/Grinder-Mixer/7.jpg)
A slide style door provides easy opening for unloading. The automatic chain oiler system oils the drive chains when the discharged auger is raised.
Hammers
![H&S Manufacturing GM 170 Grinder-Mixer](http://www.donallisonequipment.com/HS-Manufacturing/Grinder-Mixer/8.jpg)
Sixty-six thin, four way steel alloy reversible hammers reduce horsepower requirements, cutting the material - not pounding it. Cutting action occurs against the throat plate while a suction fan pulls the ground feed through the screens. This allows for a more uniform mix for ration control. Twelve screens are available with sizes ranging from 1/8'' to 2'' in diameter to grind the grain to the consistency that you desire. The mill is 21" wide.
Intake Auger
![H&S Manufacturing GM 170 Grinder-Mixer](http://www.donallisonequipment.com/HS-Manufacturing/Grinder-Mixer/9.jpg)
An optional 12" diameter by 7' long hydraulic variable speed swinging intake auger (SIA) moves grain, ear corn, shelled corn, or other miscellaneous grain into the mill with ease, and the hydraulic control allows you to keep the mill at maximum capacity.
Supplement Hopper
![H&S Manufacturing GM 170 Grinder-Mixer](http://www.donallisonequipment.com/HS-Manufacturing/Grinder-Mixer/10.jpg)
A 23" wide x 18" long supplement hopper with a sack cutter is side mounted 35" above the ground.

Magnets
![H&S Manufacturing GM 170 Grinder-Mixer](http://www.donallisonequipment.com/HS-Manufacturing/Grinder-Mixer/13.jpg)
Two heavy-duty 4" x 18" magnets remove any metal that may accidentally mix with the material entering the mill.
