[0027] When in use, first, the materials in each loading bin 1 are metered by the metering conveyor belt 2 and then transported to the primary mixing tank 1 via the grading conveyor belt 3 for initial mixing of water and raw materials. Then, the semi-finished mixture is transported to the secondary mixing tank 2 via the semi-finished product conveyor belt 51. During this transportation process, it will pass through the primary online moisture meter 1, and the monitoring data will be compared with the target data. If water replenishment is required, the variable frequency water pump 1 on the primary mixing tank 1 will be started to make the water adding pipe 10 replenish water. Then, after the secondary mixing tank 2 is fully mixed, the finished mixture is transported to the discharge hopper 6 via the finished product conveyor belt 5. During this transportation process, it will pass through the secondary online moisture meter 2 to make the final water content confirmation. If the water content requirement is still not met, the variable frequency water pump 1 on the secondary mixing tank 2 will be started to make the water adding pipe 10 replenish water until the water content of the finished mixture reaches the target water content.

When the finished product conveyor belt 5 transports the finished product mixture, it will exert a force on the finished product mixture. At the end of the finished product conveyor belt 5, the finished product mixture loses the support of the finished product conveyor belt 5 and falls down along a parabola due to inertia and its own gravity. Since the finished product mixture contains particles of different sizes, under the action of the same force, the larger the mass, the greater the inertia, and the smaller the mass, the smaller the inertia. The parabolic distances of particles of different sizes are different, causing the segregation of the finished product mixture. The utility model sets the discharge end baffle 61 to stop and shorten the parabolic distance of the finished product mixture, thereby avoiding the segregation of the finished product mixture.

[0032] Furthermore, a discharge port is provided at the bottom of the discharge hopper 6 to facilitate discharge.
