[Abstract]:Horizontal grinding machine is widely used in paint, dye, paint, ink, medicine, magnetic powder, ferrite and other non-metallic mineral industries. By analyzing the development status and trend of horizontal sand mill at home and abroad, and comparing various kinds of grinding machines, a new horizontal sand mill is designed in this paper. This paper takes horizontal sand mill as research object, synthetically uses finite element numerical simulation, mechanical design and optimization theory to complete the overall design of horizontal sand mill. Finite element simulation analysis and parameter structure optimization design of key components. The specific research contents and conclusions are as follows:. The overall design of horizontal sand mill is completed. The machine is mainly composed of power system, transmission system, grinding device, spindle, cooling system, control system, material feeding system, By analyzing the grinding mechanism of the grinding machine, the dynamic parameters, motion parameters and main working parts of the grinding cylinder are determined. Through the analysis of the working environment characteristics of each part of the grinding device, the best material is selected, and the ceramic material structure is determined in the contact part between the grinding tube and the material. Through the simulation of ANSYS software, the spindle model of horizontal sand mill is established in ANSYS software. The static analysis of the spindle and the grinding disc driven by the spindle is carried out, and the force of the spindle is obtained. The simulation results show that the designed structure meets the requirements of strength and stiffness and has the feasibility of practical production. The modal analysis of the model shows that the frequency of resonance is easy to be produced during the operation of the equipment. The dimension structure of the main transmission shaft is optimized and the optimal scheme is determined by genetic algorithm and the main shaft size is serialized.
