What are the specials of large twin-screw extruders?

After extruding the mature size of a large twin-screw extruder , the same material is cut into granular materials, translucent materials, etc., to reduce the degree of tension formed by the pre-dryer and dry surface of the material after drying. Co-adhesion also facilitates smooth compression, improves the palatability of food, changes or improves the nutritional value of pet food, and improves the digestion and absorption rate of food. The large twin-screw extruder uses advanced pelletizing structure and can The material is arbitrarily cut into the required length, the design is novel, unique, simple in structure, easy to install and easy to disassemble, easy to operate, and the oil removal adopts frequency conversion speed regulation, and is suitable for all products with low oil content and high oil content.

The feeding system, drive system and rotary cutting system of large twin-screw extruder have adopted variable frequency speed regulation, strong power, stable operation, automatic lubrication, forced cooling, ensuring safe operation of the machine, for different raw materials, choose single, double Screw feeding system, the screw is processed by special process, wear-resistant, anti-fatigue, long service life, the casing bearing should be filled with lubricating grease in time. After running for 500 hours, all the lubricating grease, screw, screw sleeve and other wearing parts should be replaced. It is strictly forbidden to use heavy hammers during the disassembly process. It is strictly forbidden to place heavy objects or stand on the expansion chamber. The expanded raw materials should be cleaned to prevent metal and other foreign materials from entering the large twin-screw extruder . The wearing parts at the material inlet wear relatively fast, and the wearing parts near one end of the feeding port wear less. Therefore, when replacing the wearing parts, they should be replaced from the discharging end in turn, and it is not appropriate to replace various parts at one time.
