With the improvement of modern manufacturing capacity and the development of various scientific research technologies, the automatic Dosage system is also constantly improving and developing. The automatic Batching system adopts the configuration system combining full sealing, pneumatic conveying and batch quantitative feeding. For dozens of materials, according to the corresponding process formula, rapid selection of batching and conveying, to a large extent, improve the efficiency of work, reduce the waste of resources, reduce the labor expenditure and save the cost of production.

Automatic feeding system in the use of PLC control programming, computer technology, automatic control technology, communication technology as one of the weighing device. PLC in the application of material mixing is also very wide, in the material configuration, production by the application of the outstanding. Among them, the production of materials in the precise proportion and mixing of the fullness of the material is particularly important. Fully automatic batching system in accordance with a variety of production needs, the production of fully automatic batching control of multiple materials programmed to achieve sequential control and cyclic control. The design is to choose a double conveyor, so that different materials into the mixing bin at the same time, in the machine before the start of mixing, the material has been mixed with a certain specific gravity, thus shortening the mixing time, reducing energy losses.

Weighing and batching system includes equipment for storage, transportation, weighing and batching of raw materials, dust removal, mixing, etc. It involves powder, solid bulk, liquid and other materials. According to the industry characteristics, production process requirements and specific material characteristics, can independently choose a reasonable batching mode, saving a lot of time and cost expenditure. Through specialization and weighing and batching, it can not only help users to improve product quality, but also provide a strong guarantee for the scientific management of user production.

Feeding system calibration in accordance with the given, weighing, speed measurement and speed regulation, feedback, after carrying out the fixed degree, the dosage of 0.5% accuracy can be absolutely guaranteed. Due to many factors affecting the accuracy of dosage, mechanical, electrical, control, equipment factors, there are human factors, so the accuracy of the dosage operation to determine whether the range of 1 %, that is, how to calibrate the dosage of accuracy is a lot of production needs to be concerned about the problem. Here are a few points on the use and control of dosage equipment: 

1. Formula bar code and material input bar code management to match, in order to avoid errors in the late formula error, bar code scanning system can be used to prevent the misplacement of the formula.

2. The material in the bulk bag unloader is conveyed via a flexible screw conveyor to a weighing hopper on a weighing module mounted on a mezzanine. The weighed batches are automatically discharged through a rotary airlock into a pneumatic conveying system that conveys the pre-weighed batches to the mixer.

3. Weigh batching is critical to be able to move material at high rates of speed for fast batching cycles and consistent delivery conveyor speeds for high accuracy weighing and to provide formulations that are not exposed to potential contaminants without having to separate the blended material.

4. Batch materials from bulk bags, silos, manual dump stations, process equipment or all materials purchased materials; weigh batch materials through filling containers and/or transport them to process containers, packaging lines or any other destination that may require equipment for a comprehensive weigh batch solution.

5. Automatically, accurately, and economically transport batches directly to common hoppers, mixers, conveyors, shipping containers, or processing containers. This loss-in-weight system is mounted on a weighing module that transmits the lost weight to the controller, which stops the conveyor once the target batch weight is reached.
