Do not use low-quality recycled materials with metal impurities or silt, and no metal objects that may fall in shall be placed near the feed port of the foam plastic grinder, so as to prevent the wear and tear of the screw and barrel from being aggravated or In the event of jamming, damage, and foam pulverizer operation, use hydraulic oil with cleanliness, viscosity and other indicators that meet the requirements, and provide sufficient flow of cooling water for the oil cooler in accordance with regulations, so as to prevent hydraulic components and pipelines from being damaged by oil. Damage phenomena such as blockage and oil leakage caused by liquid pollution or high temperature. The extruder should fill the reducer with lubricating oil that meets the requirements, and the operation of the foam pulverizer must strictly follow the requirements of the operating procedures, and no illegal operations should be performed at non-operating stations. To ensure the safety of the device, do not damage the safety protection measures of the machine for the pursuit of efficiency. When the foam pulverizer is operating, the material temperature does not reach the set temperature, and when the heat preservation time is not enough, it is not allowed to start and run the screw. Trained and familiar with the foam The operator of the pulverizer’s structural performance and operating procedures operates.
