Automatic distribution system and method for granular propellant powder

The invention mainly relates to the technical field of automatic material mixing, and provides an automatic distribution system and method for granular propellant powder in order to solve the problems that in distribution of an existing grid type mixer, the granular propellant powder depends on manual distribution, the distribution quantity is uneven, and unsafe production and uneven product quality levels are likely to be caused. The system comprises a granular propellant separator, a plate impact flowmeter, a distributor and a format mixer, and a control system sets the total weight of the granular propellant according to the actual situation and calculates the amount of the granular propellant in each lattice of the format mixer. And after the accumulated flow of the granular propellant powder passing through the granular propellant powder separator plate impact flow meter and the granular propellant powder reaches the granular propellant powder amount of one grid of the grid type mixer, the automatic mate
