How can we solve the problem of inconsistent pellet size caused by other auxiliary equipment in a feed pellet production line?

 

 

In Animal Feed Pellet Production Line, the problem of uneven pellet size is sometimes attributed to the pellet mill itself, while the influence of auxiliary systems (such as raw material conveying, screening, and dust removal systems) is ignored. Blockage in the raw material conveying pipeline leads to uneven feeding, and malfunctions in the screening system result in the failure to separate the fragments. Problems with these auxiliary systems can indirectly affect pellet uniformity. If the auxiliary systems are not checked, it is difficult to solve the problem at its root.

 

 

1.Raw material conveying system blockage or uneven feeding

 Causes: Local blockages in the raw material conveying pipeline (such as augers or elevators) due to raw material agglomeration (e.g., corn clumps exceeding 10mm in diameter) cause inconsistent feed rates; wear on the elevator buckets (creating holes) leads to partial material leakage, resulting in unstable actual raw material entering the pellet mill; fluctuations in the conveying system's motor speed (e.g., inverter malfunction) cause uneven raw material conveying speed, fluctuating raw material filling volume in the mill, and uneven pellet size.

 

 Solutions:Inspect the raw material conveying pipeline. Gently tap the pipeline with a hammer and listen for a clear sound to determine if it is blocked. If blocked, disassemble the pipeline and remove the agglomerated raw material. Install a vibrating screen (10mm aperture) at the pipeline inlet to prevent agglomerated material from entering. Replace worn elevator buckets and check the connection between the buckets and the conveyor belt for secure feeding to prevent leakage. Overhaul the conveying system's motor inverter to ensure stable motor speed (fluctuation range ≤ ±1 r/min). Install a flow sensor at the pipeline outlet to monitor raw material flow in real time and ensure uniform feeding.

 

 

2.Screening System Malfunction

 Causes: Damaged screens (cracks or holes) allow large, substandard particles or debris to mix into the finished feed; improper screen mesh selection (too dense a mesh prevents qualified particles from passing through and causes them to accumulate on the screen surface, while too sparse a mesh fails to effectively separate substandard particles); abnormal vibration frequency of the screening machine (e.g., a faulty vibration motor) leads to decreased screening efficiency and some particles not being fully screened.

 

 Solutions: Regularly inspect the screens and replace any damaged ones promptly. Select screens with mesh sizes that meet feed particle standards (e.g., 1.5-4mm aperture screens are commonly used in livestock and poultry feed production); calibrate the vibration motor parameters of the screening machine to ensure a stable vibration frequency (generally 800-1200 times/minute); install a photoelectric particle size analyzer at the screening machine outlet to monitor the particle size after screening in real time and automatically reject substandard products.

 

 

3.Insufficient Dust Collection System Efficiency
 Causes: Dust collector filter clogging (e.g., excessive dust accumulation due to lack of cleaning) leads to decreased suction, preventing the timely removal of fine powder generated during granulation. This fine powder re-mixes into the granules, causing inconsistent particle size. Abnormal fan speed (loose belt or motor malfunction) affects airflow, leaving fine powder residue. Air leaks in the dust collection duct reduce dust collection efficiency, allowing some fine powder to escape and adhere to the particle surface, altering particle size.

 

 Solutions: Establish a regular filter cleaning and replacement system (clean every 200 hours of operation and replace the filter every 6 months); check the fan belt tension and adjust it to a suitable level (the belt tension should allow it to depress 15-20mm when pressed); inspect the fan motor to ensure stable speed; seal the joints of the dust collection duct using sealant or flange gaskets; install a dust concentration detector at the dust collection system outlet to monitor dust collection efficiency in real time and ensure effective separation of fine powder.
