1. The equipment is horizontally installed on a flat concrete foundation and fixed with anchor screws (it may not be fixed according to working conditions).
2. Check if all fastening screws are tightened (the rotor center screw is an M12 left-hand screw).
3. Before use, use a special wrench to rotate the rotor and check for contact with the stator and any jamming. If the above situation occurs, do not start the machine.
4. Check and connect the power cord (three-phase AC, voltage 380V, body protective grounding) and ensure that the direction of rotor rotation is consistent with the arrow on the base (clockwise rotation).
5. Connect the cooling water and pay attention to the inlet and outlet signs of the water nozzle.
6. When starting the motor, first tap the switch to check for any noise or vibration. If the situation is abnormal, the machine should be stopped immediately, the fault should be eliminated, and then the operation should be tried again.
7. When cleaning residual materials inside the stator and rotor after work, it should be carried out in the running state. First, rotate the large chuck counterclockwise by no less than 90 ° before cleaning.
8. Method for adjusting the clearance between the stator and rotor (adjustment should be carried out during operation):
a. Loosen two handles b, move the handle to drive the large chuck to rotate, adjust the gap, and rotate the positioning disc clockwise to reduce the gap, resulting in a finer particle size of the material. Turning counterclockwise increases the gap, resulting in coarser material particle size.
c. After adjusting the clearance between the stator and rotor, both handles should be tightened simultaneously (clockwise).
d. According to the particle size and batch requirements of the processed materials, the optimal clearance between the stator and rotor can be selected to adjust the limit screw to achieve the limit purpose.
9. The butter cup should be filled with oil regularly.
10. Requirements for processing materials:
a. Cannot process dry solid materials, can only perform wet processing.
b. Before grinding, debris should be removed. The particle size of the material should be less than 1mm, and the hardness of the material should not exceed HV309. It is strictly prohibited for hard objects such as iron and crushed stone particles to enter the grinding head to prevent damage to the machine.
11. According to the material processing requirements, one or more grinding can be carried out, and several experiments should be conducted before grinding to ensure the optimal clearance and flow rate.
12. Always pay attention to the grinding operation and running time before use. If there is any abnormal situation, the machine should be stopped immediately and disassembled for inspection.
13. Dismantling of stator assembly (please note that stator assemblies 1, 2, and 3 must not be disassembled). First remove the hopper and remove the inlet and outlet nozzles, loosen the cap screws, remove the dial, hold the handle, rotate counterclockwise to remove the large chuck, and lift the grinding head cover upwards to remove the stator assembly.
14. Dismantling of the rotor assembly (please note that the first and second stage rotors of the rotor assembly must not be disassembled). After removing the stator, remove the discharge port and unscrew the left-hand screw to remove the rotor and impeller. The assembly of the rotor and stator can be carried out in the opposite order as above, and each part should be cleaned thoroughly before assembly. During installation, it is necessary to apply lubricating oil that meets the requirements on all contact surfaces and threaded parts before assembly.
15. After the colloid mill is used or not used in the short term, the inner cavity should be cleaned well to prevent corrosion, and it is best to dry it with high-pressure air. When cleaning, choose appropriate cleaning agents based on different materials, but ensure that the sealing components are not damaged (using nitrile rubber as the sealing material).
16. During disassembly and assembly, attention should be paid to ensuring that all sealing rings are not damaged, misplaced, or lost.
17. When replacing the pulley according to the required number of revolutions, first loosen the nut on the motor cover end, push the motor horizontally towards the grinding head direction to loosen the V-belt, lay down the machine, then unscrew the nut on the main shaft and the sturdy screw on the motor shaft, and remove the original pulley. When replacing the required pulley, you can gently tap it in with a hammer and do not use heavy force to avoid damaging the pulley and damaging the accuracy of the machine. After replacement, tighten with nuts and screws, and then gently stand the machine up. After the machine is erected, push the motor horizontally to tighten the V-belt, and then install the cover plate.
