Manually rotate the mill’s yoke in the horizontal position. Lock the milling chamber by engaging the Locking Bar, part 44. Loosen the mill’s locking T-screw in the yoke’s side and let it swing vertically. Remove the lid and rotate the milling chamber upside down to remove the ground media. Reverse the operations once the milling chamber is refilled with new media.

Warning: Remember to retract the Locking Bar, part 44 before closing the doors and starting the motor. Failure to retract the Locking Bar will cause damage to the machine and/or serious injury.

Grinding Chamber Rotation:

Note that the grinding chamber must always rotate counterclockwise to prevent any loosening of fasteners. To check the chambers direction of rotation, run it at the maximum rpm setting while empty, then open the door quickly to check the rotation direction.

Operational Instructions

Procedure for loading samples and grinding media:

1. Open both front doors and slide main door all the way back.
   
2. Rotate grinding chamber (RBM005-1322) by hand to locking position. Pull and rotate locking bar (RBM044) 90 degrees and release slowly into the locating hole, making sure that the tapered end of the locking bar has fully entered the hole. If necessary you may have to jog the chamber by hand to ensure the locking bar is fully engaged.
   
3. Remove the locking handle (RBM015) by turning counter clockwise.
   
4. Tilt the grinding chamber so that the lid is facing upwards.
   
5. Turn the screw handle (RBM009) counterclockwise on the yoke (RBM008-1322) until the yoke is loose enough to slide left or right and be removed.
6. Remove the lid (RBM007-1322) and place grinding charge (balls/rods) in the chamber. The charge should occupy approximately 40-45% of the chamber.
   
7. Place the sample material inside the grinding chamber. The chamber should be approximately 50-60% full with the charge and the sample material loaded.
   
8. Place the lid back on the chamber.
9. Slide the yoke (RBM008-1322) back in place and retighten it with the screw handle (RBM009).
10. Tilt the grinding chamber so the lid is facing forwards and screw the locking handle (RBM015) back in by turning it clockwise.
11. Pull and rotate locking bar (RBM044) 90 degrees and release it slowly into the unlocked position so the chamber can rotate freely.
12. 
13. Slide the main door all the way forward and make sure that both front doors are latched closed.
14. Set the timer on the control panel and press start to begin grinding operation.

Procedure for unloading samples and grinding media:

1. Open both front doors and slide main door all the way back.
   
2. Rotate grinding chamber by hand (RBM005-1322) to locking position. Pull and rotate locking bar (RBM044) 90 degrees and release slowly into the locating hole, making sure that the tapered end of the locking bar has fully entered the hole. If necessary you may have to jog the chamber by hand to ensure the locking bar is fully engaged.
   
3. Remove the locking handle (RBM015) by turning counterclockwise.
   
4. Tilt the milling chamber so that the lid is facing upwards.
   
5. Turn the screw handle (RBM009) counterclockwise on the yoke (RBM008-1322) until the yoke is loose enough to slide left or right and be removed.
   
6. Remove the lid (RBM007-1322) and remove all milling media (balls/rods) from the chamber.
7. Set your collection container/bucket beneath the chamber.
   
8. Grab the handle on the back of the milling chamber and tilt it forward to pour out the sample.
