Precautions for colloid mill installation and use

What are the precautions for colloid mill installation and use? SIEGMA will elaborate here.

1. Connect the feed hopper or feed pipe and discharge port, then connect the discharge circulation pipe, and then connect the cooling water and drain pipe.

2. After installing the electric starting device, after connecting the power supply, pay special attention to the direction of the start-up operation to determine whether the motor rotates in the normal direction. You can observe whether the rotation direction is consistent with the 'rotation direction arrow' from the feeding point. Idling and reversing are absolutely prohibited.

3. When leaving the factory, the adjusted limit screws have been installed on the block of the equipment outlet, and the gap between the grinding discs is at a standard distance. To adjust the gap between the grinding discs, first loosen the upper limit screw of the block of the discharge port, loosen the two handles on the adjusting disc 'counterclockwise' without turning on the machine, and then turn the adjusting disc 'clockwise'. Stop immediately when there is resistance. The scale of the adjustment dial is 0.01mm for each advance and retreat. Generally, under the condition of meeting the requirements of the fineness of the processed materials, the gap between the grinding discs should be kept as large as possible, and at the same time, the handle should be locked to the adjusting disc, and then the upper limit screw of the feeding port block should be adjusted to ensure the normal operation of the machine.

4. After the cooling water is connected, add about 1-2Kg of liquid material or other liquids related to the processing material, and keep the wet material in the state of returning through the circulation pipe. Then the colloid mill can be started, and the material will be put into the colloid mill for processing and production immediately after the operation is normal.

5. Before shutting down, add an appropriate amount of water or other liquids related to the processing materials in the hopper or in the cavity, and keep the wet materials in the state of returning through the circulation pipe. When starting up, it is necessary to keep a certain amount of wet material in the hopper in a state that can be returned and put in the material immediately, otherwise it will damage the hard combined seal and even cause leakage and burn the motor.

6. Pay attention to the motor load for processing materials, and reduce the feeding if overload is found.

7. When the colloid mill is in action, the discharge valve must not be closed, so as to avoid leakage caused by excessive pressure in the grinding chamber.

8. The colloid mill is a high-precision machine, with very little gap between the grinding discs and fast rotation speed. The operator should strictly abide by the post, work according to the rules, stop the machine in time when the fault is found, and then start production after troubleshooting.

9. After using the colloid mill, it should be thoroughly disinfected and cleaned in the body, so that the material does not stay in the body, so as not to damage the machine due to hard mechanical bonding.

Special precautions: Hard substances such as quartz sand, broken glass and metal chips are not allowed to be mixed with the processing materials. There must be water or liquid material in the colloid mill before and after startup, shutdown and cleaning, and idling and reversal are prohibited. Otherwise, improper operation may seriously damage the static grinding disc and the moving grinding disc, or cause malfunctions such as leakage of the mechanical seal and burning of the motor.
