Maintenance of Drum Screen

This article will explore key points for maintaining drum screens to help optimize equipment management and enhance grain silo operation efficiency.

Daily Cleaning and Inspection of Drum Screen

Regular Cleaning of Screen Mesh and Drum

During use, regularly clean the screen mesh and drum of the drum screen in the grain silo. Use tools like soft-bristled brushes, water, or compressed air to remove impurities from the mesh and drum surfaces, ensuring normal equipment operation.

Choosing Cleaning Frequency and Methods

For drum screens handling damp grain or sticky materials, daily cleaning may be necessary. For those processing dry grain, weekly cleaning is sufficient. Avoid using hard brushes or corrosive cleaners during cleaning to prevent damage to the mesh and drum surfaces.

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 to ensure smooth operation of the drive system and prevent equipment failure due to loose fasteners or damaged drive components.

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. Proper lubrication ensures smooth operation of these components, reduces wear, and extends the equipment's service life.
