[0046] The crushing stage: after the sealing is completed, the PLC controls the crushing motor 2 to work, drives the crushing roller 3 to rotate, realizes the preliminary crushing of the raw materials, and the crushed raw materials are gradually discharged from the gap between the crushing rollers 3 and fall on the screening mesh plate 5 in the processing cylinder 4.

[0047] The grinding stage: as the crushed materials are gradually discharged, the PLC controls the hydraulic push rod two 42 to work, drives the hollow connecting frame 8, the hollow ring 9 and the grinding roller 11 on the mounting seat 10 to move, controls the grinding gap between the grinding roller 11 and the screening mesh plate 5, and at the same time, the PLC controls the driving motor 6 to work, drives the rotating seat 7 to rotate, drives the grinding roller 11 to rotate synchronously, realizes the full crushing treatment of the raw materials, and avoids the different particle sizes.

At the same time, when exhausting, the air is discharged through the dust-proof mesh cylinder 26 to ensure smooth airflow and isolate the material.

[0049] Weighing stage: When the raw materials enter the weighing bucket 23, the PLC controls the electric guide rail 25 to drive the sealing ring 27 and the dustproof net cylinder 26 to move upward in the cylinder 24, so that the sealing ring 27 is separated from the weighing bucket 23, ensuring that the weighing sensor 22 can accurately weigh the raw materials in the weighing bucket 23.

When the entire equipment is closed, the air flow circulates to fully discharge the material in the weighing bucket 23, and the raw materials are transported to the mixing equipment through the mutual connection between the conveying pipe 30, the L-shaped tube 31 and the feeding cover 32.

[0051] Residual material cleaning stage: After the raw materials are discharged, the PLC controls the hydraulic push rod 40 to drive the scraper 41 to move, scraping the residual raw materials in the conveying pipe 30 and pushing them into the mixing equipment for unloading, ensuring the accuracy of weighing materials and ensuring sufficient unloading of raw materials after weighing.
