The batching precision of the energetic material weighing and batching system is an important measurement standard of a feeding system, but agglomeration easily occurs among powder particles under the action of adhesion, cohesion and the like, so that arching often occurs in the feeding process to block a storage bin, so that powder cannot be continuously and uniformly fed downwards, and bridging and material breaking are caused.

The gravity blanking of the hopper is that powder depends on dead weight, directly enters the receiving device below from the discharge port, controls the blanking amount by controlling the opening of the valve body of the discharge port, has simple structure, but cannot ensure the control precision due to the agglomeration of the powder, and stops feeding when the discharge port is blocked, needs to adopt a manual knocking or hole tamping method to dredge the discharge port, not only influences the production efficiency, but also has potential safety hazards. The screw discharging device is characterized in that the screw rotates under the driving of external force, powder enters a spiral gap on the screw, and the powder is conveyed along with the rotation of the screw. The spiral feeding device has the advantages of high feeding speed, easiness in manufacturing the feeder, simplicity and convenience in installation and controllable feeding process, is suitable for various powder materials, including powder materials with poor flowability, but has poor stability of a feeding system due to instability of a filling coefficient; in addition, when the screw device rotates, a larger friction force and a larger extrusion stress are easily formed in the gap, so that potential safety hazards are caused. The electronic belt scale type discharging device is characterized in that an electronic belt scale is arranged below a storage bin, the storage bin discharges materials to the belt scale, the belt scale weighs the discharging mass and feeds the discharging mass back to a discharging mechanism to control the material mixing speed; the electronic belt scale type weighing batching system has no stress on powder, and the belt is made of antistatic material, so that the method is safe, but in order to solve the dust problem, the belt is placed in a dustproof outer cover, the mechanism in the dustproof outer cover is complex, a large amount of dust is still accumulated, and the method is only suitable for places with large batching range and low precision requirement. The vibration conveying and discharging means that the vibration feeder performs reciprocating motion under the action of a vibration motor, electromagnetism or pneumatics to realize the throwing movement of powder; the method has no extrusion to the powder, has good safety, but has poor precision to the powder with poor fluidity and easy agglomeration.
