Weighing and mixing machine including raw material storage body, conveying body, weighing and dosing body, dust removal body, material mixing body and other equipment; dosing mode, according to the characteristics of the industry, the requirements of the production process, mixing machine, specific material characteristics, a reasonable choice of "zero method" or "reduce the amount of the method of weighing" and other ways of weighing, with a single hopper single material, single hopper multi-materials, multi hopper multi-materials and other modes of operation.

The hopper on which the loss of weight bulk is exported to the bulk bag discharger provides sufficient capacity to allow the primary ingredient, which is conveyed at a lower rate, to be reloaded by the small diameter flexible screw conveyor. Conveyed by the weight loss flexible screw conveyor is the secondary ingredient, which is manually dumped in either one or two dumping stations equipped with a vacuum filtration system containing airborne dust. All flexible screw conveyors discharge into a common shoulder weight transition hopper mounted on a load cell, which confirms the accuracy of a batch of fed material prior to passing it through a rotating airlock into the pneumatic line described above.

It enters into the electric arc valve from the material bin, and then sent into the punch plate Electronic scale by the screw Feeder, the flow size is measured by the punch plate electronic scale, and the speed of the screw feeder is adjusted according to the actual need of the electronic scale, so as to realize the normal feeding of the material. Through the measurement of the punch plate electronic scale, it enters into the feeding box of the screw pneumatic conveying pump, and advances forward through the feeding mechanism, enters into the mixing room and is gasified by the air from the fan outlet, and is sent into the conveying pipeline.

In the above process, the screw conveyor plays the role of quantitative flow stabilization, not only can accurately measure the flow of powder and can detect whether the powder in the system is out of material, the screw pneumatic conveying pump plays the role of locking the wind, but also play a role in conveying materials. Control system, our control program adopts advanced bus technology, can easily use ProFibus, MOD-BUS, Ethernet and other communication methods to complete the high-speed communication with the PLC system, with a strong real-time Weighing system, good reliability, flexible configuration, etc., which can conveniently meet the needs of various types of users for weighing and batching.
