Using computer automatic batching, the batching accuracy is good, the quality is stable, the effect is good, the speed is fast, the economy is practical, and the mechanization and automation degree are high. The microcomputer controller adjusts the belt speed according to the size and direction of the calculation deviation to achieve the set target value, thereby achieving quantitative feeding. After the measurement of each material is completed, it enters the mixing machine to evenly mix various materials, and then enters the automatic packaging scale for packaging and storage of finished products
