tin tức công ty về Why is my fish food extruder machine experiencing abnormal load?

Three reasons

1.

Feeding speed too fast (overload noise)

Cause: The feeder is running too fast, feeding too much raw material at once. The pellet mill's rollers and screw can't keep up, causing material to clog the machine, leading to motor overload and a muffled "humming" sound (much louder than usual). The motor will also overheat and may even trip.

Solution: The feeding speed should match the pellet mill's capacity. Don't try to feed too fast—for example, if the pellet mill produces 1 ton per hour, adjust the feeder to feed 1 ton of raw material per hour (check the feeder's scale or flow meter). If you notice the motor overheating or the noise increasing, slow down the feeding speed and gradually increase it back once the machine returns to normal. Don't push it too hard.

2. Ring Die Blockage (Pressure Stagnation Noise)

Causes: Raw materials that are too wet, have too coarse a particle size, or have excessive wear on the die holes can cause material to clog the ring die, leading to pressure stagnation – the pressure rollers cannot rotate, the motor is overloaded, producing a muffled "clunking" sound, and may also result in broken material or no material output.

Solutions: Immediately stop the machine, remove the ring die, and use a drill to remove the material blocking the die hole (do not use hard objects to smash it, as this will deform the die hole); if the die hole is too worn, replace the ring die. Regularly control the moisture content and particle size of the raw materials to prevent blockage, as blockage not only causes noise but also delays production.

3. Unstable Voltage (Volatile Noise)

Causes: Rural power grid voltage sometimes fluctuates (e.g., low voltage during peak electricity consumption). When the motor operates under unstable voltage, its speed will fluctuate, producing a "humming" noise, and may also cause motor overload and shorten its lifespan.

Solution: Install a voltage regulator on the pellet mill (choose one that matches the motor power, for example, a 20 kW voltage regulator for a 15 kW motor) to stabilize the voltage at 380 volts (three-phase). During peak electricity usage, try to avoid using it simultaneously with other high-power equipment (such as welding machines or water pumps) to reduce voltage fluctuations.
