[0019] The first sorting machine 6 lower end discharge end is equipped with the coal belt conveyor 26 for transporting the clean coal;

[0020] The second sorting machine 7 lower end discharge end is equipped with the pyrite belt conveyor 27 for transporting the pyrite.

[0021] Working principle:

[0022] The storage bin 1 is used for storing the coal gangue raw materials to be processed, and the raw materials are preliminarily piled and arranged to prepare for subsequent processing.

[0023] When the coal gangue raw materials in the storage bin 1 reach a certain amount, the feeder 2 is started to continuously and uniformly convey the coal gangue raw materials to the breaker 3.

[0024] The breaker 3 is used for receiving the coal gangue raw materials from the feeder 2 and crushing them into smaller particles through strong crushing force.

[0025] The crushed coal gangue is conveyed to the first elevator 4 through the first belt conveyor 5, the first elevator 4 lifts the coal gangue to a certain height through the lifting mechanism, and then sends the coal gangue into the first sorting machine 6 through the discharge port.

[0026] The coal gangue is preliminarily sorted in the first sorting machine 6, and different quality materials are separated according to particle size and density and other characteristics. Some of the separated materials may contain valuable components such as clean coal, which is transported out by the clean coal belt conveyor 26, and the remaining materials enter the second sorting machine 7 for further sorting to remove more impurities and unqualified particles. The second sorting machine 7 is provided with a pyrite belt conveyor 27 at the discharge end for transporting out the separated by-products such as pyrite;

[0027] The qualified coal gangue particles after sorting are lifted to the coal gangue storage bin 10 by the second elevator 9 for temporary storage, providing stable raw material supply for the subsequent sand making process;

[0028] The coal gangue in the coal gangue storage bin 10 is transported to the sand making machine 11 by the third belt conveyor 12. The sand making machine 11 further crushes and shapes the coal gangue particles into required sand particles by impact and shearing principles;

[0029] The sand particles produced by the sand making machine 11 are transported to the vibrating screen 13 by the fourth belt conveyor 14 for screening. The vibrating screen 13 classifies the sand particles by particle size using the vibration principle. The qualified products fall into the collection device below the screen, and the unqualified products are returned to the sand making machine 11 for reprocessing by the return belt conveyor 15, ensuring the uniformity of particle size and the stability of quality of the finished sand;

[0030] The screened finished sand is transported to the third elevator 16 by the fifth belt conveyor 17. The third elevator 16 lifts the finished sand to a certain height and then sends it into the finished sand storage bin 18 through the discharge port for storage;

[0031] The sand particles in the finished sand storage bin 18 are accurately metered and controlled by the metering screw 19. The metering screw 19 adjusts the speed and discharge amount according to production requirements to ensure the accuracy of raw material ratio in the subsequent mixing process;

[0032] The metered finished sand and other ingredients such as cement and water are sent into the mixer 21 through the metering hopper 22 for mixing and stirring. The mixer 21 uses the rotation and shearing action of the stirring blades to fully mix and uniform various raw materials, forming the required dry-mixed concrete;

[0033] The mixed dry-mixed concrete is packaged by the packaging machine 23. The packaged concrete products are transported to the palletizing robot 25 through the conveying line 24 for automatic palletizing according to the preset program and parameters. The palletizing robot 25 neatly stacks the concrete products on pallets or shelves for outbound or transportation.

[0034] In summary, the coal gangue preparation dry mixing concrete production device realizes efficient conversion of coal gangue and production and preparation of dry mixing concrete through a series of orderly process steps and equipment cooperation. The entire production process has high automation degree, high production efficiency and stable and reliable product quality.
