Description

Technical Field

[0001] The utility model relates to the technical field of ball mill discharging, and specifically relates to a ball mill discharging device. Background Art

[0002] Ball mills are widely used because they can process a wide range of materials, from fragile to hard, and from small to large particles. They are used in industries such as mineral processing, metallurgy, and chemicals. Their primary function is to grind and mix materials. They mix and crush materials through high-speed rotation and grinding, thereby achieving changes in the particle size distribution and properties of the materials.

[0003] When a ball mill has too much grinding media or the material is too fine, overflow may occur, meaning some material overflows from the discharge port. This not only wastes material but also hinders subsequent cleanup. Overflow and material that does not reach the required particle size must be reprocessed or discarded, increasing the cost of raw materials. Therefore, we propose a ball mill discharge device to optimize the discharge process. Utility Model Content

[0009] Compared with the prior art, the beneficial effects of the present invention are: when the ball mill is in use, a discharge structure is set at the discharge pipe of the ball mill, so that the discharge pipe is closed, which effectively prevents overflow when the ball mill is working, avoids the problem of polluting the working environment and wasting materials, and without the interference of overflow, the operation of the ball mill will be more stable. At the same time, the discharge structure has a disassembly function, which can be removed when discharge is required and can be easily disassembled as needed, which makes maintenance and overhaul work more convenient and reduces unnecessary waste of time.

[0021] Working principle: Before using the ball mill body 2, a discharge structure 4 and a discharge pipe 3 are pre-set. The cylindrical ring 41 in the discharge structure 4 is fixed in the inner cavity of the discharge pipe 3. The inner cavity of the cylindrical ring 41 is conical, and the inner ring wall has a certain inclination to facilitate subsequent discharge. At the same time, a rubber ring 42 is set on one side of the cylindrical ring 41, and a circular plate 44 is sleeved in the inner cavity of the discharge pipe 3, and the clearance with the discharge pipe 3 is matched. The circular plate 44 can be pushed by the pull rod 45.
