[Abstract]:With the development of mining, cement and other industries, high efficiency, energy saving, superfine grinding equipment demand is exuberant. The maintenance of vertical spiral stirred mill is increasing continuously. It is imminent to develop a large vertical spiral stirred mill with independent intellectual property. Based on the development of a large vertical spiral stirred mill, the following research work has been carried out. (1) In the test rig of spiral stirrer mill, the test of no pulp mill was carried out, the discrete element model of mill was established and simulated. The experimental and simulation results showed that the simulation of the discrete element model of the mill coincided with the actual operation, and the difference of the performance of the spiral stirrer mill, the rod type stirrer mill and the grinding mill's grinding mill were analyzed. The ore efficiency is better than that of the rod mill. (2) the test of the pulp mill was carried out in the test bench of the spiral stirrer mill, and the computational fluid dynamics - discrete element coupling model of the mill was established. The experiment and simulation analysis of the grinding effect and the change law of the resistance moment of the spiral agitator were of guiding significance to the design of the large vertical mill. (3) the use of the separation was used. The discrete element method, the discrete element model of the 320t mill is established, the performance analysis is carried out, the resistance moment of the spiral agitator is obtained, the finite element model of the spiral agitator is established, the resistance of the spiral agitator is applied, the structural strength of the spiral agitator is analyzed, which provides the basis for the design and manufacture of the mill, and the starting time of the agitator and the grinding machine The influence of the structure strength of the agitator is analyzed, which provides the basis for the selection of the mill reducer and the selection of the medium. The research work has passed the acceptance of the enterprise experts, and provides the theoretical basis for the development of the large mill. The large mill can be manufactured according to the plan, the outlet, the installation and use, and the actual measurement of the structure strength of the large mill. It is basically consistent with the research in this paper.
