The centralized feeding system is an overall solution capable of realizing centralized feeding and control so as to realize the unattendedcontinuous forming operation of the whole plant. It is designed according to the placing conditions of machine stations on the customer site and the consumption of site raw materials as well as the combination of unique auxiliary equipment. Industrial computer is adopted in this system to conduct centralized control over all machine stations automatically, thus realizing thecontinuous feeding operation (24 hours) of all consuming units. It can perfectly realize the special requirements of raw materialdehumidifying, drying, deliver, dosing, and mixing after matched with special functions of each machine station within the system. Thecentralized feeding system is equipped with multiple monitoring and protection functions. The operation is safe and reliable. It is the core precondition for the enterprise to realize an unattended factory.
