Double tube spiral quantitative feeder
The double tube spiral weighing feeder is also a dynamic measuring instrument suitable for conveying powdered, granular or small materials. Unlike the single tube spiral scale, the double tube spiral scale has a two-layer structure, with the upper layer mainly responsible for stabilizing flow and conveying, and the lower layer mainly responsible for dynamic measurement. The stable flow effect is good and space saving, and the process layout is flexible, easy to install, disassemble and move. Widely used in industries such as cement, feed, chemical, food, medicine, papermaking, and environmental protection.

Speed sensor
Speed sensors with cast aluminum armor thrive outdoors – rain or shine. Brushless DC pulse generator design = zero upkeep.
Working Principle
The material is transported by a screw conveyor from the feeding port to the measuring cutter connected below, and the fully weighed weight of the measuring screw is sent to the controller through three tension sensors installed on the measuring cutter as a voltage signal proportional to the weighing load, along with the preset cutter speed data (when measuring with double pipes, the measuring cutter runs at a constant speed to advance the material, that is, the speed signal is the design value of the measuring cutter).
At this time, the weight and speed signals are calculated to obtain the instantaneous flow rate and cumulative weight value. The control system of the spiral quantitative feeding scale compares the actual flow rate signal with the set flow rate signal, and outputs the control signal to the frequency converter through PID adjustment. The speed of the feeding cutter is dynamically adjusted to achieve quantitative feeding.
