The following key points need to be paid special attention when installing the drum screener machine to ensure the safe and stable operation of the organic fertilizer equipment and achieve the expected screening effect:

1. Select the installation position: Ensure that the installation position is smooth, strong, and can withstand the weight and vibration of the screen. You need to consider the surrounding space and ensure that there is enough space for operation and maintenance.

2. Foundation preparation: The screening machine usually needs to be installed on a concrete foundation to ensure that the foundation is smooth and stable, and can support the weight of the equipment and vibration during operation.

3. Level adjustment: Before installation, use a level to adjust the levelness of the screening machine to ensure the horizontal position of the screen frame and drum to avoid unnecessary vibration and uneven screening effect.

4. Fixing and connecting: Ensure that the various parts, bolts and connectors of the screen machine are firmly fastened, especially the connection of the drum and the transmission system. Install and adjust the drive system correctly according to the installation instructions provided by the manufacturer to ensure the tension and correct operation of the belt or chain.

5. Test run and commissioning: Before formal use, test run and commissioning are carried out to check whether the organic fertilizer production line is running normally, whether the transmission is smooth, and whether the components are working well. Adjust the clearance and vibration amplitude of the screen or drum to achieve the desired screening effect.

6. Safety protection: Ensure that the necessary safety protection devices are installed around the equipment, such as protective covers, safety switches, etc., to avoid the operator's contact with the moving parts and avoid accidental injury.
