High Frequency Screening Procedure

Here is a table summarizing the procedure for high frequency screening:

| Step | Procedure |

| ---  | ---       |

| 1    | Prepare the material to be screened and ensure it is evenly distributed on the feed tray. |

| 2    | Adjust the inclination angle of the screen and lock it in place. |

| 3    | Turn on the high frequency screening machine and adjust the amplitude and frequency settings according to the material being screened. |

| 4    | Begin feeding the material onto the screen surface at a controlled rate. |

| 5    | Monitor the screening process and adjust the amplitude and frequency settings as required to ensure high screening efficiency. |

| 6    | Collect the screened material into designated containers based on the particle size. |

| 7    | After screening is complete, turn off the machine and clean it carefully. |

| 8    | Analyze the screened material and repeat screening if necessary. |

It's important to follow the manufacturer's guidelines and user manual when operating the machine to ensure safe and efficient screening operations.
