The homogenized weighing and feeding system is a metering device that continuously weighs and controls various solid material silos, material tanks, liquid tanks and other materials. Through processes such as weighing and feeding, formula control, mixing and homogenization, and material conveying, it is an integrated automated system that combines microcomputer control and data management. A high-performance control platform is built by using Mitsubishi or Siemens series PLCS and industrial control microcomputers. For the design of an automation system for production control, it is necessary to achieve stable and reliable operation, simple and practical operation, as well as superior cost performance.

The feeding system is composed of main components such as a mechanical scale frame, feeding mechanism, stainless steel weighing module, speed sensor, weighing instrument, drive part, frequency converter, and control cabinet. It is a production measurement equipment that controls the feeding, dynamic measurement, and continuous transportation of powdered materials. A balanced Weighing system that mixes and measures several substances in the object being weighed according to a pre-given mass ratio. The weighing system is divided into single-tube single-layer and double-tube double-layer types. The single-tube single-layer structure simultaneously completes measurement and transportation, while the double-tube double-layer structure has the upper layer for flow stabilization and transportation, and the lower layer for measurement and transportation. It has a better flow stabilization effect and saves space.

The DCS control system is adopted, and the pneumatic, stop and operation of the entire system are controlled and monitored in the control room. The entire equipment is equipped with a fault detection system. When the back-end equipment malfunctions, the front-end equipment will automatically stop and display the location and cause of the fault. The system's operating status will be indicated by alarm lights. The three-level control mode is adopted. The weight signal from the material in the silo is transmitted to the microprocessor controller, which automatically calculates the actual weight of the material or the height inside the silo. Convert the weight or height of the material into a 4-20MA transmission signal. The upper and lower limit values of materials can be set, and the feeding and discharging equipment can be controlled to keep the actual materials within the set range.
