Four Roller Granulators in Laiyang, Shandong: Key Points for Commissioning

2026-09-08

At the roller granulation production line site in Laiyang, Shandong, four roller extrusion granulators are in the final stages of installation. Technicians are adjusting the gap between the rollers, which needs to be maintained between 0.3-1mm to ensure that the rollers do not collide and can effectively bite into the material. The equipment has specific requirements for the feed particle size, usually not greater than 0.5mm. The material moisture content needs to be controlled within the range of 2%-5% to ensure the dry extrusion molding effect. Currently, construction workers can be seen checking the gear meshing and adjusting the belt tension. The equipment transmission system consists of a motor, pulleys, reducer, and chain sprockets. The reducer is connected to the drive shaft through a nylon pin coupling. Synchronous rotation of the rollers is ensured by open gears, ensuring relative movement between the two rollers. The entire line is still in the electrical wiring and no-load test run stage, with construction cables and tools left on the ground.
