During the actual utilization process of ring die pellet mill, situation that the machine can operate normally without any fault is the premise for high working efficiency and continuous production. However, failures are inevitable. As long as the failure is carefully analyzed and quickly resolved, the time for production will not be delayed.

1. The evident productivity decrease of ring die pellet machine

Fault cause: High water content in raw material; The falling off or damage of inner parts; Severe abrasion of hammer; Uneven feeding; Excessive slowness of rotating speed or belt slip

Handling method: Drying the material in the sun; Overhauling the motor; Adjusting the angle or changing new hammers; Even feeding and full load in operation; Ensuring the revolving speed of ring die pellet mill and tightening the belt.

2. Oversize finished products

Fault cause: Severe abrasion of sieve or holes in the sieve; Loose connection between sieve and sieve holder

Handling method: Mending or changing the sieve; Halt for examination

3. Strong vibration of ring die pellet mill

Fault cause: Wrong installation order for hammers; Swing-out failure of some hammers; Damaged bearings; Shaft distortion; The looseness of foundation bolt

4. Reverse spraying of feeding mouth

Fault cause: Congestion in fan blower or delivery pipe; Over-wet material or congestion in sieve hole; Overfilling in powder collector or excessive feeding

Handling method: Cleaning the congestion and examining the abrasiveness of fan blower; Drying the material in the sun or widening the sieve hole; Timely discharging or reducing feeding; Changing the powder collector according to the required size. Enhancing the maintenance work for ring die wood pellet mill is also an effective way to prevent the machine being damaged. Thus the maintenance work is indispensable to the high performance of ring die pellet machine.
