The invention discloses an improvement of a nutation centrifugal ball mill mechanism and a mounting method. The improvement comprises (1) a flexible limiting and adjusting device and a mounting method, (2) an improvement of a winnowing method and an air replenishing port, and (3) a wear cavity wear-resistant liner shape and a mounting method. In the flexible limiting and adjusting device and the mounting method, a rubber ring on an adjusting ring achieves a recoil effect on tipping force load of a cross bearing; in the improvement of the winnowing method and the air replenishing port, the airflow is smooth, the powder separation efficiency is high, and fresh air replenished by air introduced from the external of a wear cavity achieves a cooling effect on the wear cavity; and a wear-resistant liner is a wear-resistant liner body consisting of upper and lower liners, is larger in material selecting space, and can effectively reduce the wear consumption.
Description
technical field [0001] The invention belongs to the technical field of powder grinding, and in particular relates to a high-efficiency ball mill or self-grinding or semi-self-grinding powder without the limitation of "critical speed" for media balls and materials to obtain high-strength three-dimensional centrifugal force acceleration through mechanical nutation motion grinding equipment. Background technique [0002] Existing powder grinding equipment, such as traditional cylindrical ball mills, autogenous mills, and semi-autogenous mills, are limited by the "critical speed", and the grinding media (balls or rods) and materials can only be thrown at a relatively low acceleration of gravity. The material is ground by falling or leaking. The equipment cannot effectively transmit kinetic energy to the medium and materials, so the energy consumption is very high. Compared with the traditional barrel ball mill, the nutating centrifugal ball mill can be regarded as a ball mill ...
