Colloid mill installation, use and maintenance precautions

1. **Installation and Setup**

- Place the milling mill on a flat concrete foundation, horizontally.

- Secure with anchor screws if required by operating conditions.

- Tighten all fastening screws, especially the rotor center screw (M12 left-hand screw).

- Rotate the rotor with a dedicated wrench to check for contact with the stator or jamming before use.

2. **Power and Cooling Setup**

- Connect to a three-phase AC power supply (380V) with proper grounding.

- Ensure the rotor rotates clockwise as indicated by the arrow on the base.

- Turn on the cooling water supply, following the inlet and outlet markings.

3. **Startup and Operation**

- Start the motor and check for noise or vibration. Shut down immediately if abnormalities occur.

- Clean residual material from the stator and rotor while the machine is running, rotating the large chuck counterclockwise by at least 90° before cleaning.

4. **Stator/Rotor Clearance Adjustment**

- Adjust clearance while the machine is running:

- Loosen handles, rotate the large chuck clockwise to decrease clearance (finer particles), or counterclockwise to increase clearance (coarser particles).

- Tighten handles simultaneously after adjustment.

- Use limit screws to set the desired clearance based on material particle size.

5. **Maintenance and Cleaning**

- Regularly oil the oil cup.

- Clean the machine interior after use or non-use periods to prevent corrosion.

- Use appropriate cleaning agents without damaging nitrile rubber seals.

- Ensure seals are not damaged, misplaced, or lost during disassembly and assembly.

6. **Material Processing Requirements**

- Only process wet materials; dry solid materials are not allowed.

- Remove debris and ensure particle size is less than 1 mm and hardness does not exceed HV309.

- Avoid hard objects like iron or stone to prevent machine damage.

7. **Pulley Replacement**

- Loosen the nut on the motor cover and adjust the motor to loosen the triangular belt.

- Replace the pulley by gently tapping it with a hammer.

- Secure the new pulley, tighten the belt, and replace the motor cover.
