Now your Country Living Grain Mill can be even more versatile! Use the large auger to mill corn, beans, and coffee. To use, simply replace the standard spring auger with this larger auger. The large auger is cast from stainless steel.Note: There are thousands of corn hybrids and not all of them grind equally well. The Country Living Mill does best with hard corn with a low moisture content. Soft varieties of corn, or corn with a soft or chalky interior tends to clog and grind poorly.
