To ensure the uniform mixing of raw materials, the discharge rate from the lower part of each weighing screw of the weighing screw machine is controlled by frequency conversion adjustment. Due to the time lag in the flow of materials to the next silo caused by the distance between each silo, it is necessary to ensure that each ingredient is evenly and continuously covered on the material layer, which is accurately and error-free achieved through the automatic control system. After various raw materials are continuously mixed in the proportion set by the process, they are conveyed to the feeding position of the batching tank.
020-34563445The lower part of each storage bin of the weighing screw machine is equipped with a discharge screw, which sends the raw materials to the lower hopper scales respectively for various raw material measurements. The lower part of each hopper scale is equipped with a feeding screw, and frequency conversion control is adopted. According to the process setting, the raw material weight is uniformly and continuously discharged once. The discharge volume is calculated and controlled by the weight difference of each hopper scale. To ensure the accuracy of each discharge quantity; All kinds of raw materials are sent from the hopper scale to the summary mixing screw conveyor through the feeding screw for uniform mixing. They are then conveyed by the bucket elevator to the mixing screw conveyor and finally sent to the batching tank. The start and stop of batching in each tank are manually controlled, and the batching process is fully automated. The batching process is mainly controlled by the PLC control system, which uses the difference method to control the output volume through the reading of the weighing module. Each raw material is accurately and evenly discharged in the quantity set by the process.

After various raw materials are continuously mixed in the proportion set by the process, they are conveyed to the feeding position of the batching tank. Dust removal facilities are required at each dust-raising point in the mixing process. To ensure that operators can have an excellent working environment. The weighing accuracy during the process can reach +0.5kg. The batching process is fully automatically controlled according to the set parameters of the process, ensuring safe, stable, accurate and reliable operation.
