The suction metering mixer is equipped with an activated hopper and a vaporizer at the bottom of the storage bin. During the discharge process, the continuous vibration of the activated hopper and the purging of the vaporizer ensure smooth material descent. Moreover, the eccentric oscillation module can be used to adjust the vibration amplitude to enhance efficiency and the frequency of vaporization purging. When conveying materials, the conveying volume and efficiency can be changed by adjusting the air time and material time of the air knife valve, which is helpful to meet some links with high requirements for the crushing rate. The pulse interval and pulse width can also be adjusted to prevent dust leakage from the receiving bin during the conveying process.

After the weighing mixer reads the data through PLC communication, it then executes the corresponding operation. Meanwhile, the PLC moves the monitoring signals to be collected by the touch screen into the communication storage area. By reading the data in it, the touch screen can monitor it on the PC. The entire system is connected in series through pressure elements, Weighing modules, etc., to achieve industrial automation. This not only improves the conveying efficiency but also effectively prevents dust leakage. It provides good environmental protection for on-site workers.

The powder conveying system is a system that achieves the purpose of powder conveying through vacuum suction, generating a strong negative pressure inside the tank. The powder conveying system achieves the purpose of powder conveying through vacuum suction, and integrates comprehensive factors such as filtration, reverse blowing, discharging, and valve body control. The system is mainly applied to the transportation of powdery materials, granular materials, powder-granular material mixtures and other materials. The system can automatically convey various materials to the hoppers of packaging machines, injection molding machines, crushers and other equipment, and can also directly convey mixed materials to mixers and various mixing reaction tanks, solving the problem of dust during feeding and reducing the labor intensity of workers. It is the preferred system for powder conveying.

Compared with the traditional feeding and conveying methods, the powder air flow conveying system mainly has the following characteristics:

(1) The flexible configuration of the conveying pipelines makes the factory's production process flow more rational.

(2) The conveying system is completely enclosed to prevent dust from flying and escaping, ensuring environmental hygiene.

(3) It has few moving parts, making equipment maintenance and repair convenient and reducing labor intensity.

(4) It has a high efficiency in bulk material conveying, reducing the costs of packaging, loading and unloading, and transportation.

(5) To prevent the conveyed materials from getting damp, contaminated, or mixed with foreign objects such as wires and ropes, thereby ensuring the quality of the conveyed products;

(6) During the conveying process, multiple process operations can be carried out simultaneously, such as mixing, crushing, classification, drying, cooling, dust removal, etc.

(7) It can achieve remote operation of concentrating materials scattered at multiple points to one place or dispersing materials from one place to multiple points. According to the requirements of the formula and process, it can be conveyed in batches to reduce waste.

(8) It can achieve online automatic weighing, with precise weighing and small error.
