Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of ball mills, and more specifically, particularly relates to a ball milling mechanism for aluminum ash pretreatment. Background Art
[0002] Aluminum ash is mainly composed of metallic aluminum, aluminum oxide, silicon dioxide and a small amount of other oxides. The metallic aluminum contained in it has significant recycling value, and non-metallic components such as alumina can also be further refined or applied to other industrial fields. Aluminum ash ball mill, as a key equipment to achieve efficient crushing of aluminum ash and preliminary separation of metallic aluminum, plays a core role in the aluminum ash resource utilization chain.
[0003] The traditional aluminum ash ball mill is based on the principle of drop grinding, that is, aluminum ash enters the cylinder of the ball mill through the feed port, and the cylinder is filled with steel balls of a certain size as grinding media. When the cylinder rotates, the steel balls cling to the inner wall of the cylinder under the action of centrifugal force and rotate with the cylinder. After reaching a certain height, they fall under the action of gravity, forming an impact and grinding on the aluminum ash. The metal aluminum particles are deformed in the repeated collision and grinding of the steel balls, thereby achieving a preliminary separation from other components. Subsequently, the finer aluminum particles gradually move to the bottom of the cylinder under the action of the feed inertia and are transported to the discharge end through the single-layer partition plate. However, during the movement of the aluminum ash slag to the discharge port, the sieve holes of the single-layer partition plate block the large pieces of aluminum ash slag, resulting in the accumulation of large pieces of aluminum ash slag near the single-layer partition plate. The large pieces of aluminum ash slag cannot be fully crushed and screened, and it hinders the finer aluminum particles from passing through the single-layer partition plate, thereby reducing the processing efficiency of the aluminum ash ball mill.

The inclined surface of the single-layer partition plate 7 makes the large pieces of aluminum ash slag move back along the inclined surface under the action of gravity and feed inertia. The moved back aluminum ash slag is impacted and crushed by the steel balls again, ensuring that the grinding process of the aluminum ash slag inside the first cylinder 4 is fully and evenly ground. The large pieces of aluminum ash slag are gradually refined in the process of repeated impact, return and re-impact until they reach the particle size standard set by the single-layer partition plate 7, thereby improving the crushing efficiency of the aluminum ash slag and the processing efficiency of the ball mill body.

Two T-shaped sliding grooves 13 are provided in an annular manner on the inner wall of the ring 71, and the two T-shaped sliding grooves 13 are symmetrical to each other. The T-shaped sliding grooves 13 are arranged in an arc shape, and a sliding ball 12 is slidingly arranged in the T-shaped sliding groove 13, which limits the sliding ball 12 to move only along the direction of the T-shaped sliding groove 13 to prevent the sliding ball 12 from falling out, thereby ensuring the stability of the plurality of U-shaped fixing seats 91 during the telescopic process. The sliding ball 12 is connected to the connecting column 11 through the connecting column 11 The plate 10 is connected, and the connecting column 11 has its own elasticity.
