company news about Do you know how to troubleshoot feed production line malfunctions?

Troubleshooting should be conducted according to the principle of "segmented equipment location." First, check for blockages in the crusher: Open the feed inlet and observe. If the raw material accumulates above the screen, it's likely due to an excessively small screen aperture or wear and deformation. Replace the screen with one of matching aperture (80-mesh screens are commonly used for corn crushing, and 100-mesh for soybean meal). If the blockage is inside the crushing chamber, it may be due to severely worn hammer blades (dulled edges), preventing effective crushing of the raw material. Measure the hammer blade thickness; if the wear exceeds 2mm, replace it immediately. Next, check for blockages in the screw conveyor: After turning off the power, remove the conveyor cover. If the raw material accumulates at the feed end, it's likely due to an excessively fast feed rate exceeding the equipment's conveying capacity. Slow down the feeder speed. If the blockage is in the middle of the conveyor, it may be due to foreign objects (such as corn stalks or plastic bags) entangled in the blades. After cleaning, check for blade deformation; if deformed, correct it.

Blockages caused by different raw materials require targeted treatment. When processing high-moisture raw materials (such as fresh distillers' grains and wet corn), blockages are often caused by material adhesion. A drying process should be added before feeding to control the moisture content to 12%-15%. When processing high-fiber raw materials (such as alfalfa meal and straw meal), blockages often originate from fibers entangled in equipment components. A screen for removing impurities should be installed at the feed inlet, and the equipment cleaning interval should be shortened from once per hour to once every 30 minutes. A beef cattle feed mill reduced the blockage rate by 70% by installing a magnetic separation device at the feed inlet of its straw crusher.

The core of preventative measures is establishing a mechanism of "standardized pretreatment + routine equipment inspection." After raw materials arrive, they are first screened to remove stones, metal, and other impurities. Then, the crushing parameters are adjusted according to the characteristics of the raw materials. The condition of the crusher hammers and conveyor blades is checked before starting the machine daily, and the equipment interior is thoroughly cleaned weekly to prevent residual raw materials from becoming moldy and clumping, leading to blockages.
