Description

  • 1/5 horsepower (150 Watts) motor develops a torque of 2.2 kg-cm (30 oz-inches) at 12,000 rpm
  • Temperature is maintained by means of built-in heat exchangers
  • Control panel has an overload protection reset button and a pilot light
  • Tubing connections 6.4mm (1/4") on the cover and housing accept tubes for circulating water or slurry
  • Cover, grinding assembly and milling blade head are removable for cleaning
  • Stainless steel chamber is 54mm diam x 25mm deep (2-1/8 x 1") inside an aluminum housing with an epoxy finish and non-skid rubber feet

FEATURES:
The Micro-Mill Grinder consists of three separate assemblies:
1. The base which houses the controls and driving motor.
2. The lower grinding chamber which contains the cutter assembly and mounts on top of the base.
3. The upper grinding chamber which encloses and locks to lower grinding chamber.

NOTE: Both the upper and lower grinding chambers have a built-in heat exchange for cooling or heating.

OPERATION:
If the Micro-Mill Grinder is clean and completely assembled, the operation proceeds as follows:
1. Remove upper grinding chamber by releasing the latches and lifting it off.
2. Place test sample into the lower grinding chamber. A sample must have a volume between 20mL and 50mL. Lesser or greater amounts will not result in adequate milling. Note: Samples must be dry if they are to be milled. Moist or oily substances will build up on the blade. Freezing such samples will permit them to be ground. Cooling the chamber is recommended for the frozen samples. In many instances, pieces of dry ice placed in the grinding chamber with the sample will suffice.
3. Replace upper grinding chamber by inserting the pins through the holes in the back plate on the lower grinding chamber. Fasten latches, left one first.
4. If heat-exchanger facilities are to be used, make the necessary connections to the hose ends on the grinding chambers.
5. Set timer to any desired milling interval up to 5 minutes. When machine stops, open the chamber and check the results. Reassemble and restart the unit if more grinding time is required. Use the continuous position of the timer for grinding intervals over 5 minutes. The model which does not have a timer is equipped with a hold-down type switch. It is necessary to keep this switch depressed for the length of time sample is to be milled.
6. Remove upper grinding chamber, lift off lower grinding chamber and pour out milled material. Brush out particles with a soft camel hair brush.
7. After cleaning all parts, reassemble and place on the base. when placing lower grinding chamber on the base, make certain the drive coupling and alignment pins engage and seat. DO NOT FORCE; if in line, the chamber will drop in place.

CAUTION:
1. Do not restrict or block air flow into the base assembly.
2. Do not leave unit on if motor stalls or runs slowly.
3. Before cleaning cutting head, disconnect mill from power source.

AVAILABLE ACCESSORIES:
