What are the Precautions for the Use and Operation of Granulators?

What precautions should be taken when using and handling Plastic Granulators? Let's have a look!

Precautions:

1. After the machine is installed according to the requirements, before using the machine, you must refer to the instruction manual in detail to be familiar with the structure of the machine and the functions of the switches and buttons of the electric box. It should be operated by those who are familiar with the technological process so that measures can be taken in time to prevent the occurrence of accidents in the event of an accident during the commissioning process.

2. Before starting the machine, check whether the lines are connected correctly, and check whether the supply of water and electricity is normal.

3. Gear lubricating oil must be added to the reduction box (generally, the company has added it when it is produced). The amount of oil added is based on the oil that can be seen by the liquid level gauge. It cannot be too little or too much; check whether the oil pump is working properly.

4. When using the new machine, first heat the machine to the required temperature.

5. When the machine is out of use, first open the waste valve to drain the stored materials in the box. After the pressure of the box drops, turn off the scraper switch and the waste switch, then turn off the motor of the hydraulic station, and turn off the switches of each heating zone. Turn off the main power switch.

6. When the machine is restarted, first heat it to the required temperature (to melt all the plastic in the cavity), open the waste discharge, and after the plastic flows out, then start the scraper, close the waste valve, and enter into production.

7. When the output is reduced during production, it may be that the holes of the stencil are blocked. The extruder should be stopped first, the waste valve should be opened, and the stencil should be replaced after the pressure of the box body drops.

8. When replacing the screen plate or scraper, the waste valve must be opened first. After the pressure of the box body drops, the cover plate screw is removed, and finally the screen plate or scraper is replaced.
