Feeding system is a kind of production equipment used in industry for processing different powder or liquid materials in certain proportion automatically and accurately, which usually consists of Weighing system, weighing control instrument, PLC system and upper computer. Weighing system includes raw material storage body, conveying body, weighing and dosing body, dust removing body, material mixing body and other equipments; the dosing method can be reasonably selected according to the characteristics of the industry, the requirements of the production process, the specific characteristics of the material, such as "incremental" or "decremental" weighing method, with a single hopper single material, single hopper multi-materials, multi hopper multi-materials and other modes of operation.

The feeding system utilizes PLC as the central control area to complete the whole process of weighing and feeding. The PLC central control area sends out a signal to start the corresponding solenoid valve to inject the liquid into the reaction kettle, and at the same time, the weighing module starts to work. When the amount of liquid in the reaction kettle increases to the same value as the weight set by the quantitative setting finger, the central control area receives the action signal from the weighing module, and immediately closes the solenoid valve for adding liquid and stops adding liquid. Automatically start the stirring switch, the control area sends out the instruction to start the corresponding solenoid valve of the mixer and the timer set by the program starts to time, the mixer stirs the solution evenly; when the timer time reaches the set value, the control area sends out the instruction, the solenoid valve closes and the stirring stops.

Dosing equipment performance characteristics:
