Common Faults and Troubleshooting Methods for Granular Organic Fertilizer Production Line Equipment:

Fault 1: No particle output when the mold hole is blocked while driving.

Possible causes:  1. Template hole corrosion.  2. Template hole corrosion with poor surface finish.  3. Excessive clearance between the template and the roller.

Exclusion methods: 1. Remove residual particles from the mold hole. 2. Grind with high-oil-content powder. 3. Adjust the gap to 0  1-0.  3 ㎜

Fault 2. Excessive powder content or failure to form granules.

Possible reasons:  1. The material has excessively low moisture content.  2. The material has excessively high moisture content.  3. The material contains a high proportion of coarse fibers.

Exclusion methods: 1. Increase moisture content. 2. Decrease moisture content. 3. Add viscous powder

Fault 3: Output gradually decreases.

Possible causes: 1. Excessive gap between the template and roller. 2. Template blockage.

Exclusion method: 1. Adjust the template and roller clearance. 2. Clean the template

Fault 4: Particles become hard and shiny.

Possible causes: 1. The material has a low moisture content.

Exclusion method: 1. Increase the moisture content of the powder material

Fault 5: The particles become soft, with a rough surface.

Possible causes: 1. Improper moisture content. 2. New formwork in initial use.

Exclusion methods: 1. Reduce or increase moisture content. 2. Use oil-containing powder for extrusion and grinding

Fault 6. The granulator suddenly dies.

Possible causes: 1. Hard materials or metal objects have entered between the template and the roller.

Exclusion method: 1. Remove foreign objects
