Electronic quantitative packaging weighers by weighing unit, trolley, FengBao conveying device, pneumatic system, dust removal system, quantitative packaging control instrument and so on, the whole process is controlled by computer, weighing automatic.
Proportion to stone machine is working, the materials come into inlet from constantly into people go to the central stone on the surface of the screen. As a result of the vibration sieve surface and airflow through the material layer, increase the intergranular porosity, materials in the fluidized state, promoted the automatic grading, than big stone sink bottom and sieve surface contact, the proportion of small food float to the top, under the impetus of the gravity, inertia and continuous feeding, falling to the net grain exports; Under the influence of inertia force and airflow of the vibration system of the screen surface, the gravels, which are more important than the gravels, slide relative to the screen surface and move to the selected area through the aggregate area.
As a metal detection device, it is composed of metal detector and automatic elimination device, in which the detector is the core part. The system can use the alarm signal to drive the automatic elimination device and so on, so as to remove metal impurities from the production line.
Color picker is a process of using CCD optical imaging technology to screen different color particles and impurities in color picker. After the materials to processing site to determine the proportion of different color particles and impurities (a) the impurity rate, the rate of impurity in the material directly affect the color of separator color accuracy, the higher the rate of impurity color choose the lower precision. Therefore, before starting up the machine, relevant parameters such as the operating mode of the color picker are set according to the heterogeneity, output and type of the material.
