Description

Technical Field

[0001] The utility model relates to the technical field of ball milling devices, in particular to a ball milling device for producing silicon carbide powder. Background Art

[0002] The production of silicon carbide powder usually involves the process of crushing silicon carbide raw materials to finer particle sizes. A ball mill is one of the commonly used equipment to complete this process. The ball mill uses grinding balls loaded in a rotating cylinder to crush the materials through collision and grinding between the grinding balls and the materials. In the production of silicon carbide powder, the selection and operation parameters of the ball mill have an important impact on the particle size, purity and production efficiency of the final product. Publication No. CN219943042U discloses a ball mill including an inner cylinder, a sphere, an outer cylinder and a driving mechanism. A plurality of spheres are arranged in the inner cavity of the inner cylinder. The inner cylinder is arranged in the outer cylinder. The outer wall of the inner cylinder is spaced from the inner wall of the outer cylinder to form a receiving cavity, and the outer wall of the inner cylinder is partially in contact with the inner wall of the outer cylinder. The outer wall of the inner cylinder is provided with a plurality of sieving holes connecting the inner cavity of the inner cylinder and the receiving cavity. The outer wall of the outer cylinder is provided with a plurality of discharge holes, which are connected to the receiving cavity, and the driving mechanism is connected to the outer cylinder in a transmission manner. The ball mill device of the utility model connects the driving mechanism only with the outer cylinder, and the driving mechanism only needs a small rotational force to drive the outer cylinder, which can effectively reduce the output power of the driving mechanism, reduce energy consumption, and thus reduce production costs, and the material in the accommodating chamber can be further ground by rolling on the outer wall of the inner cylinder and the inner wall of the outer cylinder, further improving the grinding quality of the material. The ball mill device has a simple structure and high grinding efficiency. Although the product has good grinding efficiency and quality, it is impossible to screen the material after discharge, and the material cannot be directly screened according to the required size. Workers are required to collect the material and then transport it to a suitable screening device for screening, thereby reducing the efficiency of material screening processing, and the practicality is poor, and improvement is needed.
