What are the maintenance and care methods for fertilizer belt conveyors?

Maintenance and Care Methods for Fertilizer Belt Conveyors: This is a highly practical topic, as proper maintenance can significantly extend the service life of the equipment. The core conclusion is: Fertilizer belt conveyors require attention to four key aspects—daily inspections, cleaning and lubrication, component maintenance, and protection under special working conditions—along with regular standardized operations.

Daily Inspection and Cleaning

Before daily startup, check the conveyor belt tension. Excessive looseness can cause slippage, while excessive tightness may accelerate wear. Adjust to the appropriate state via the tensioning device.

Clean the residual fertilizer on the surface of the conveyor belt and the frame to prevent the accumulation of powdered or granular materials, which could lead to corrosion or jamming of components.

Inspect the rotation flexibility of the drum and idlers, address any jamming or abnormal noises promptly to prevent affecting the conveyor belt operation.

Lubrication and maintenance

Regularly add lubricating oil to the motor and reducer of the drive unit, selecting the appropriate model according to the equipment manual. Generally, replace it every 3-6 months.

For rotating parts such as roller bearings and idler bearings, apply grease monthly to reduce friction wear and prevent rusting or jamming.

After lubrication, remove excess grease to prevent the adsorption of dust and fertilizer particles, which can cause secondary wear.

Maintenance of Key Components

Conveyor belt: Avoid contact with sharp objects. Promptly repair or replace any tears or damages. When edges are severely worn, adjust the belt misalignment to prevent further damage.

Drum and idler: Regularly inspect the surface wear condition. Replace promptly if depressions or rust occur. Maintain drum surface cleanliness to prevent material adhesion and uneven belt tension.

Tensioning device: Inspect the integrity of the lead screw and spring, ensure the adjustment function operates normally, and prevent conveyor belt slippage caused by tension failure.

Special Working Conditions and Long-Term Parking Protection

In humid environments, regularly apply rust-proof paint to the racks and metal components to prevent fertilizer corrosion and moisture erosion.

During long-term shutdown, loosen the conveyor belt, clean all equipment thoroughly, cover with a dust cover, and protect it from sun and rain exposure.

Due to the unique characteristics of fertilizer transportation, regularly inspect the sealing condition of the equipment to prevent material from entering critical components such as motors and reducers.
