Maintenance of Drum Screen

As an efficient screening device, the stable operation of a drum screen is crucial for grain quality and production efficiency. This article focuses on the maintenance of drum screens, exploring how scientific maintenance measures can ensure their efficient operation.

Daily Cleaning and Inspection

Cleaning the Screen Mesh and Drum

During use, the screen mesh and drum surface of the drum screen can easily accumulate grain residues and impurities. This not only affects the screening effect but may also cause screen blockages and drum wear. Therefore, regularly cleaning the screen mesh and drum is fundamental to the maintenance of the drum screen.

Choosing Cleaning Frequency and Methods

Determine the appropriate cleaning schedule based on the frequency and type of grain processing. For drum screens handling damp grain or sticky materials, daily cleaning may be necessary. For those processing dry grain, weekly cleaning is sufficient.

Inspection and Maintenance of Key Components

Inspect Fasteners and Drive Components

Regularly check the fasteners of the drum screen, such as bolts and nuts, to ensure they are not loose. Also, inspect and maintain drive components like belts, chains, and bearings. Add lubricating oil or replace worn parts in a timely manner.

Implementation of Lubrication Maintenance

For rotating components of the drum screen, such as bearings and motors, follow the equipment manual for regular lubrication maintenance. Typically, clean and lubricate the bearings every 200 - 300 working hours.

Monitoring Operating Conditions and Storage Management

Monitoring Equipment Operation

If abnormal phenomena are detected, such as high motor current, unusual operating sounds, or excessive drum vibration, stop the machine immediately for inspection. Identify and resolve the issue to prevent more serious equipment faults.
