Parts List and Exploded Views
The QCG 4E Electric Disk Grinding Mill is used in fine testing labs around the world. The 4E
electric grinding mill head construction is made of sturdy, durable cast iron. The 4E head is
heavily coated with a special TIN coating acceptable for food grade and pharmaceutical
materials and makes clean up between batches relatively simple and complete as the surfaces
of the mill and auger are very smooth.
The 4E grinding mill head can be easily removed and disassembled for cleaning without the use of any special tools.
The grinding plates are made of a hard iron alloy designed for clog resistance and long life. A new, special acicular iron grinding plate has now been introduced as an up-charge. The acicular plates offer a stronger plate that “work hardens” as they are used in service.
Plate to plate clearance is easily adjusted by hand in order to change the mesh size range
desired. Generally these mills, with a one pass effort and fine plates installed, yields ground
material between 20-80 mesh with some yield down to 100 mesh. Instituting a second pass
thru the grinding mill increases yields in the finer mesh sizes.
A rigid cast aluminum base and bearing support minimizes overall weight. 3 point rubber pads or feet are present on the base for stability.
Low current requirements, needs no special wiring. Just plug it in and hit the switch after mounting the grinding head to the base. The complete unit ships in two boxes.
The customer has the choice of either 4B Plates for fine grinding or 4CS Plates for coarser grinding.
The customer has the choice of either Tooth Feed auger for dry grinding or Worm Feed auger for wet or oily grinding.
