At the top of a mill the big pieces of rock, sometimes the size of a soccer ball, were fed into a giant metal jaw that would crush them up until the smaller pieces fell between a metal grating called a "grizzly"; socalled because the spacing between the grating was about the width between the claws of a grizzly bear (about 2 inches).
The diameter of ball used will vary between 12 mm and 125 mm W o r k i n g The ball mill is used for the grinding of a wide range of materials and it copes with feed up to about 50 mm in size. The material to be ground may be fed in through a 60 degree cone at one end and the product leaves through a 30 degree cone at the other end.

The length of each core run should be limited to 3 m ma ximum. Core run lengths should be reduced to m (5 ft), or less, just below the rock surface and in highly fractured or weathered rock zones. Shorter core runs often reduce the degree of damage to the core and improve core recovery in poor quality rock.

The tale of our hard rock mill build continues. We knew the RP4 Shaker Table can separate gold 1 micron in size. For those who would like a comparison a micron is .000039 inches. The average human hair (we're talking head hair not my grizzled beard) measures approx. .0035 inches. So, 1 micron is around 2,000 times smaller than a human hair. Wow!
