The weighing mixer takes the weighing module as the core to control other equipment to complete the batching. The particles are driven by the screw conveyor to fall from the silo into the hopper. There are a total of 6 channels, each conveying different materials. The running speed of the screw conveyor is adjusted by the frequency converter according to the output voltage of the weighing module. When actually batching, the formula and batch of batching are set through the keyboard of the weighing instrument. The Weighing system automatically selects the required silo, sends instructions to drive the screw conveyor motor, and makes the material fall into the hopper. The weighing module on the hopper outputs the weighing signal, which is then controlled by the weighing module to adjust the speed of the screw conveyor and control the feeding amount, so that the end value reaches sufficient accuracy. When the batching is completed, the door opens automatically, and the materials enter the mixer for mixing. The weighing module automatically calculates the mixing time. After the mixing is completed, the finished materials are discharged. To achieve the automated production of the weighing mixer, weighing systems are respectively designed and installed in the mixing silo and the buffer silo to precisely control the weight ratio of each component of the particles and conduct analysis to meet the best daily ratio requirements. To achieve remote control of the above-mentioned equipment and facilitate users to view and manage the equipment anytime and anywhere, an Internet of Things gateway is adopted. The wireless gateway collects data from the weighing system and then transmits the data wirelessly to the user's mobile device, thus realizing the monitoring of the equipment's operating status and data.

The particles coming from the weighing mixer enter the mixing silo through the feeding pipe. After being pre-dried by the bypass air, they fall into the upper inlet of the screw conveyor through the discharge pipe. The materials are sent into the rotating silo by the rotational movement of the screw conveyor device. The mixer is driven by the main motor to rotate the cylinder through a reducer and open gear transmission. The particles are lifted to a certain height through the rotational movement of the silo. During the free falling and throwing process, the particles impact and mix the materials until the materials are ground and mixed into powder. Before entering the mixer, it is divided into two paths, one of which is the side path air. The side path air has two functions. On the one hand, it mixes with the particles in the mixing bin to pre-dry the materials. On the other hand, maintain sufficient wind speed for conveying the powder in the powder pipeline. Another path is the human mixing air, which enters the mixer's chamber to convey and dry the powder inside. The air-powder mixture is carried out of the mixer through the annular channel between the central pipe and the hollow pipe of the screw conveyor. The powder material, the incoming mixed air and the side air are mixed together in the screw conveyor and then enter the separator. The separator is equipped with blades that can adjust the fineness of the powder material, and the fineness of the powder material can be adjusted as required. The coarse-grained substandard powder material is returned to the particle tube through the return pipe by gravity and mixed with the particles for re-grinding and mixing. After being separated by the separator, the qualified powder material is conveyed to the burner through the powder material outlet and the powder feeding pipeline, and then sent into the reactor for batching.
