The working method and characteristics of loss-in-weight feeder

The weightlessness scale is composed of a hopper, a feeder (single and double-shaft screw feeder), a weighing system and a regulator. In operation, the hopper, material and feeder are jointly and continuously weighed. After the material is sent out, measure the true weight loss rate and compare it with the required weight loss rate (set value). The weightlessness scale automatically corrects the deviation from the set point by adjusting the feeder rate. Thus, the material can be continuously fed evenly and accurately. The suitable range of weightless scale includes plastic granules, powder, calcium carbonate, talcum powder, resin film powder, flour, starch, etc. Among them, there are various solutions for different raw materials, which can solve the existing production process. The problem that occurred in. The company's weightlessness scale has core technology and independent research and development strength, and has rich engineering application experience in many fields and industries. This weightlessness scale has the following unique functions and advantages: (1) Wide application range, particles, powder, calcium carbonate , Talcum powder, resin film powder products, flour, starch, etc.; (2) The original mechanical parts of the weightlessness scale such as screws are easy to decompose, simple to assemble and easy to clean; (3) Strong technical strength, professional pre-sales guidance Service team; (4) Stable cutting performance, high accuracy, and a large range of optional conveying capacity; (5) The static accuracy of the weightless scale system reaches 0.1%; the linear and repeatable dynamic accuracy reaches 0.3%; (6) The weightless scale control The instrument uses a high-precision weightlessness scale controller, which has the advantages of high accuracy, strong anti-interference, and good real-time performance; the sensor adopts a high-precision sensor module, and the sensor adopts laser welding, which has the advantages of high accuracy and good reliability, and is especially suitable for Application sites with harsh working conditions; (7) The control system of the weightlessness scale is flexible: the control system of the weightlessness scale can realize manual and automatic control of feeding and replenishment processing, and can realize manual and automatic conversion
