The selection of gear oil for pet food extrusion equipment machines should revolve around three core factors: equipment type, workload, and ambient temperature. Different scenarios require significantly different gear oil models. First, clarify the core indicators of gear oil: viscosity grade and extreme pressure anti-wear performance. Extrusion pellet mills often have heavy-duty gearboxes, requiring extreme pressure industrial gear oil to avoid lubrication failure due to the inability of ordinary machine oil to withstand heavy load impacts.
Small cat food making machines (motor power 2.2-7.5kW) have lower transmission loads and relatively stable operating temperatures (40-60℃). A viscosity grade of 150# extreme pressure industrial gear oil is recommended. These machines have small gearboxes with oil chamber capacities typically of 1-2L. 150# gear oil offers a balance of fluidity and lubrication, forming a stable oil film under light load conditions, and is easy to add and change. For example, mini fish feed extrusion pellet mills have simple transmission systems; 150# extreme pressure gear oil is sufficient for lubrication needs. Using a higher viscosity 220# gear oil would result in insufficient lubrication during low-temperature starts due to its poor fluidity.
Single-Screw pet food extrusion machines (motor power 15-30kW) operate under medium loads, with gearbox temperatures reaching 60-80℃ during continuous operation. 220# extreme pressure industrial gear oil is recommended. These machines are often used in small feed mills, running continuously for 6-8 hours daily. 220# gear oil has a higher viscosity and stronger extreme pressure anti-wear properties, maintaining oil film stability under medium loads and higher temperatures, effectively reducing gear wear. If the production environment is cold in winter (below 0℃), 150#-220# multi-grade gear oil can be used, balancing low-temperature fluidity and high-temperature lubrication.
Twin-Screw fish feed extruder machines (motor power 30kW and above) experience heavy transmission loads, with gearbox temperatures often reaching 80-100℃. 320# high viscosity extreme pressure industrial gear oil is required. These machines use large gearboxes that bear the enormous torque of the high-speed screw rotation. 320# gear oil possesses excellent extreme pressure anti-wear, anti-oxidation, and heat dissipation properties, enabling long-term stable operation under heavy loads and high temperatures. For some imported brand extrusion pellet mills, it is necessary to strictly follow the recommended type of special gear oil in the equipment manual to avoid affecting the equipment warranty due to incompatible oil quality.
