Screw batchers realize the automated dosing and mixing process, the key principle of which is the application of load cells. In the weighing and batching equipment, the weighing module is mainly used to detect the weight change of the material in the hopper, and through the weight change to realize the automated metering and the switching of the material dosage drums in the hopper, which in turn ensures the dosage and mixing accuracy of different granule and powder materials. The equipment realizes the automation and accurate measurement of the material formula through the automated continuous measurement process, and also ensures the consistency and uniformity of the mixing. In order to ensure the accuracy, effectiveness and stability of mixing, the dosage control system needs to formulate relevant control strategies according to process parameters, equipment characteristics and material properties, so as to realize the standardization and normalization of automated production.

Weighing Feeder is composed of modules such as metering module, microprocessor control module, driving motor, weighing control system and actuator, and its working process mainly includes several steps of weighing, metering, mixing and discharging. Firstly, the material enters into the hopper through manual or automatic loading device. Then according to the preset dosage and mixing ratio, the accurate automatic Dosage system measures the required raw material weight from different materials, and controls the switching and toggling of the raw material bucket through the change mechanism, thus controlling the adjustment of the formula ratio and the metering accuracy of the actual dosage. In the process of material feeding, because the density of materials is different, it is necessary to set the number of blocks of the respective Electronic scale for different materials in the weighing process to realize accurate measurement.

According to the recipe setting, the system automatically starts the motor, according to the established process parameters, using the mixer for mixing, mixing time and speed generally according to different material characteristics, specifications, adhesion and subsequent processing process requirements, to set different parameters. When the mixing time arrives, the system automatically discharges the mixed materials through the discharge port to continue the production process of the next batch of materials.
