Powder automatic feeding system is a complete set of automation equipment to realize dynamic weighing and batching control through electrical control management and visualized man-machine software configuration. The electrical control part of the system adopts Siemens PLC, which is programmed and controlled according to the production requirements; the software adopts man-machine configuration, which controls the weight and flow of the materials loaded into the weighing hopper through the monitoring system and PLC program according to the process requirements, thus realizing the accurate measurement and batching. With strong stability and high cost performance, the system can provide accurate measurement data and control means for production control and management of various industrial sites.

The feeding system adopts Siemens series PLC, circuit breaker, relay, frequency converter and terminals, all of which are famous brands at home and abroad. Compact structure, stable work, full-featured, with overload, short-circuit, phase failure and other protection, can complete the equipment automation and process automation control. The dosage Weighing system can be integrated with existing conveyor weighing systems for warehouse and package picking terminals. TLX Advanced helps you to provide dosage control for revenue, optimized inventory control, cost savings and improved operational processes. At the same time, the configuration control, i.e., data acquisition, uses high-end configuration software as a host computer, through which commands are issued to manage the automation equipment and processes. Standard industrial computer software and hardware platforms are used as the integration carrier to replace the traditional system, which is characterized by strong adaptability and good openness.

The weighing design allows you to build customized configurations, choosing exclusively from automated weighing systems or validation options, allowing the operator the opportunity to enter missing information, TLX can be customized to meet specific customer requirements. Configurable software allows modular design for each customer, data acquisition systems can be customized to meet the needs of each application, and the weighing system features an industrial touch screen with optional image acquisition.

Feeding system due to the role of pressure, the material from the sending tank into the conveying pipe, compressed gas through the solenoid valve a certain frequency of opening and closing the formation of pulse gas flow (gas knife), with the aid of the gas knife pressure is greater than the pressure of the sending tank will be cut into the material bolts, relying on the bolts before and after the difference between the static pressure as the impetus to push the material forward to the separating device for implementation of the separation of the material and gas separation, the material fell into the silo, the gas is discharged into the atmosphere, the realization of the conveyor. Adopt compressed gas as power source as conveying medium. The use of mandatory pneumatic conveying, relying on closed pressure vessel (sending tank) as a sender, the general pressure of the gas source for 0.5Mpa ~ 0.7Mpa, the operating pressure of 0.3 ~ 0.5Mpa, sending tanks can only be taken to intermittent conveying, conveying distance of up to 1,000m or more. Materials in the pipeline at a lower speed, dune state, fluidization or agglomeration state conveying method is called positive-pressure dense-phase conveying. High-pressure Roots fans can also be used. According to the conveying characteristics, the system can also be divided into positive-pressure dense-phase dynamic pressure conveying and positive-pressure dense-phase bolting conveying two ways. Material with low speed dune state or fluidization in the pipeline is called dense-phase dynamic pressure conveying; material with lower speed to the agglomeration state in the pipeline is called dense-phase embolism conveying.

System characteristics:

1) lower flow rate but large conveying capacity, almost no effect on the quality of the material;

2)The system has higher pressure and lower gas consumption;

3) Control system automation, high requirements for various electrical components;

4) Multi-point feeding and multi-point unloading is possible;

5) low wear and tear on pipelines and materials due to low material conveying speed; and

6) the warehouse pump is a pressure vessel, for the mandatory signing of the equipment;

7) The gas source is generally screw air compressor, post-processing equipment must be matched;

8)The system is reliable and less maintenance, but the quality of the operator and technician is required to be high.

9) small amount of conveying gas, material and gas separation is easy to realize

10)Higher working pressure, so it can realize long-distance conveying; the use of boosters can realize ultra-long-distance conveying.
