With the rapid development of modern breeding industry, the use of feed processing equipment is becoming more and more widespread. Among them, feed extruders have become the preferred equipment for many farms due to their advantages of high efficiency, energy saving and improved feed quality. However, the stable operation and service life of the equipment depend largely on scientific and reasonable maintenance. This article will systematically introduce the maintenance methods of feed extruders to help breeding companies reduce equipment failure rate and improve production efficiency.
The feed extruder is mainly composed of a feeding system, a spiral extrusion mechanism, a heating system, a cutting device, an electronic control system and a transmission part. Its working principle is to use the rotation of the spiral shaft to extrude, heat and expand the raw materials, and extrude them through the mold to form finished feed. When the equipment is running, the mechanical and electrical components are subjected to greater pressure and temperature, and maintenance is particularly important.
Ensure the normal operation of equipment: Regular maintenance can reduce equipment failures, improve production stability, and avoid production interruptions caused by equipment downtime.
Extend the service life of equipment: Good maintenance can effectively reduce mechanical wear, extend the service life of core components, and reduce the frequency of replacement.
Ensure product quality: The equipment is in good condition, which is conducive to stabilizing the feed extrusion effect, improving the feed expansion degree and nutritional value.
Reduce production costs: reduce maintenance costs and production stoppage losses, improve energy utilization efficiency, and save operating costs.
Daily maintenance
Cleaning work: After work every day, the surface and residual raw materials inside the equipment should be cleaned in time to prevent agglomeration and corrosion. Focus on cleaning the extrusion screw, die mouth and feed port to avoid blockage.
Check the lubrication system: Lubrication is the key to reducing mechanical wear. Check the grease of each lubrication point daily to ensure that the grease is sufficient and free of pollution. Screw bearings, gear boxes and other components should add or replace lubricating grease according to the instructions.
Tightening inspection: Regularly check each connecting bolt and fastener, and tighten them in time if they are loose to prevent components from falling off or being damaged due to vibration.
Electrical inspection: Observe whether the electric control cabinet and motor are running normally, whether there is abnormal noise or heating, and ensure the safety of electrical components.
Periodic maintenance
Mold inspection and replacement: The mold is a key component that determines the quality of feed molding. Check the degree of mold wear regularly. If the mold aperture becomes larger or the shape is abnormal, it should be replaced in time to ensure uniform pellets of finished feed.
Screw wear inspection: The screw works under high temperature and high pressure, which is prone to wear. The screw should be disassembled and inspected at regular intervals to determine whether it needs to be repaired or replaced.
Drive belt adjustment: Check the tightness and wear of the drive belt to avoid slippage affecting power transmission. If the belt is loose or severely worn, it should be adjusted or replaced in time.
Cooling system maintenance: If the equipment has a cooling system, check whether the cooling water pipe and radiator are unobstructed, whether there is blockage or leakage, and ensure the cooling effect.
Quarterly and annual maintenance
Comprehensive overhaul: It is recommended to conduct a comprehensive equipment overhaul every quarter or at the end of the year. Including disassembly and inspection of key components such as main bearings and gearboxes, cleaning, overhaul or replacement of damaged parts.
In-depth inspection of the electrical system: Insulation test the electrical components, check the working condition of the terminals and relays, and prevent leakage and short circuit accidents.
Thoroughly clean the equipment lubrication system: replace all lubricating grease, clean the oil system, and prevent impurities from clogging and causing poor lubrication.
Correction and adjustment: Correct key moving parts to ensure the concentricity of the screw rotation, accurate mold installation, and uniform extrusion.
Strictly follow the equipment manual: The maintenance details of different models of feed extruders are different, and should be carried out in accordance with the technical manual provided by the manufacturer.
Train operators: Strengthen the equipment maintenance knowledge training of operators, improve their maintenance awareness and skills, and reduce man-made damage.
Use appropriate lubricating materials: Lubricating grease should meet the equipment requirements, and avoid using inferior grease to cause accelerated wear of mechanical parts.
Regularly record maintenance logs: Establish equipment maintenance files, record the time, content and replacement parts of each maintenance in detail, and facilitate tracking of equipment status.
Introduce intelligent monitoring systems: Use sensors and Internet of Things technology to monitor equipment temperature, vibration and lubrication status in real time, give early warnings, and reduce sudden failures.
Formulate scientific maintenance plans: Combine the frequency of equipment use and operating conditions to reasonably formulate maintenance cycles to avoid excessive or insufficient maintenance.
Purchase high-quality accessories: Choose original accessories supplied by regular manufacturers to ensure equipment performance and compatibility.
Keep the working environment clean: The equipment should be placed in a dry and ventilated environment to avoid dust and moisture affecting mechanical properties.
