For example, in the industries of biomedicine, chemistry and chemical engineering, superhard diamond, powder metallurgy, rare earth permanent magnet and the like, so that the improvement of the uniformity of powder mixing is always the field which is continuously pursued by cumin in the powder preparation industry.

The powder mixing method is roughly classified into two types, namely a gravity convection diffusion type and a forced shearing stirring type, and the powder mixing equipment mainly adopts a certain mixing method to realize the mixing function.

The gravity convection diffusion type mixing method is a mixing method which enables powder to repeatedly flow, diffuse, impact, fold and other movements by constantly changing the weight center of the powder in a mixing bin and utilizing gravity, and has the function of enabling the powder to be blended and permeated in a macroscopic view, so that the aim of uniform mixing is achieved; the defects are that the change speed of the local space between the adjacent particles on the microcosmic scale is slow, the mixing uniformity is low, and the requirement of fine mixing can not be met, and the mixing equipment using the mixing method comprises the following steps: three-dimensional mixers, v-mixers, double cone mixers, etc., which are typically used in mixing operations requiring less uniformity of mixing, such as batch mixing.

The forced shearing stirring type mixing method is a mixing method for forcibly stirring and shearing powder repeatedly by utilizing a moving blade in a fixed mixing bin, and has the functions of breaking up the adjacent relation between the powder on a microscopic level, enabling the powder to move and exchange fully and achieving the purpose of uniformly mixing the powder; the disadvantage is that the integral uniformity of the powder in the container in the upper, lower, left and right macroscopical directions can not be realized, because the powder which can not be contacted by the blade is mixed only, and the powder which can not be contacted by the blade is in a relative static state and does not participate in the mixing, the mixing efficiency is lower, and the requirement of industrial mass production can not be met, and the mixer utilizing the principle has the following advantages: the method and the device are generally used in mixing working links with low requirements on mixing efficiency, such as long mixing working time or small-batch production.

In addition, the chinese intellectual property office discloses a powder high-efficiency mixing container and a powder mixing method thereof, wherein the publication number is CN 111068554 a, and the container and the powder mixing method thereof provide a powder high-efficiency mixing container and a powder mixing method thereof, which improve the powder mixing efficiency by improving the inner wall shape of the container, so that the container wall generates disturbance effect on the powder flow, and the probability of relative movement between the powder is increased. Although the application generates disturbance effect on powder flow by improving the inner wall form of the container, the disturbance is very limited, the local space change speed is very slow, the adjacent relation between the powder cannot be quickly broken up, and when the powder meets sticky powder or powder with overlarge specific gravity difference, the mixing equipment and the mixing method cannot solve the problem.

The efficient powder mixer comprises a machine base, a hopper cylinder, a motor and propellers, wherein the hopper cylinder is fixedly supported on the machine base, the hopper cylinder is in a conical body, the side wall of the hopper cylinder is provided with a feed inlet, the bottom of the hopper cylinder is provided with a discharge outlet, valves are arranged at the feed inlet and the discharge outlet, the top of the hopper cylinder is fixedly provided with a cover plate, the motor is arranged on the cover plate, the bottom surface of the cover plate is fixedly provided with three bearing supports, each main shaft is arranged on the cover plate and the bearing supports through bearings, the output shaft of the motor is in transmission connection with the main shaft, the lower end of each main shaft is provided with the propellers, the three propellers are uniformly distributed in the material box along the circumference, the three propellers are arranged at the positions from top to bottom in the material box, the propellers are three-blade symmetrical wing-shaped propellers, the rotating directions of the three propellers are the same and are the right rotating directions, the, the height of the top surface of the paddle is gradually reduced from the center to the two sides. The utility model discloses a although set up multiunit stirring vane, can improve the intensity of mixing, nevertheless it can't make all treat that mixed powder is done all-round, the high-speed of large-span flows in a hopper section of thick bamboo, so it still can't solve the problem that the mixing efficiency is low, the degree of consistency is general.

It can be seen that the powder mixing apparatus and method in the current market have disadvantages, and cannot meet the requirements of the powder mixing apparatus and method that the market urgently needs to improve the mixing uniformity and mixing efficiency.
