磨机运行时筒体内部负荷是工艺人员进行决策的重要参数,是工艺系统优化的基础。SINO铁矿φ12.2 m×11.0 m自磨机采用Loadcell传感器测量磨机负荷,存在稳定性差、数值漂移等问题。通过对现场试验数据进行分析,研究磨机转速、油温等因素对轴承油压的影响,以及滑履轴承油压不均对负荷的影响,最终建立了由滑履轴承油压计算磨机负荷的数学模型;将由此模型计算的磨机负荷与现场Loadcell测量的磨机负荷进行对比和修正后,相对误差小于3%。该方法具有实施成本低、精度高和稳定性好等优点,便于现场应用与推广。
The internal load of the cylinder during the operation of the mill is an important parameter for the process personnel to make decisions and is the basis for the optimization of the process system. SINO iron ore φ12.2 m × 11.0 m Self-mill Loadcell sensor measuring mill load, there is poor stability, numerical drift and other issues. Through the analysis of the field test data, the influence of mill speed, oil temperature and other factors on the bearing oil pressure and the influence of the oil uneven pressure on the load of the shoe bearing were studied. Finally, the load of the oil- The relative error is less than 3% when the mill load calculated by this model is compared with the mill load measured by Loadcell on-site. The method has the advantages of low implementation cost, high precision and good stability, and is convenient for field application and promotion.
