Sinoma Bangye (Hangzhou) Intelligent Technology Co., Ltd. and Tianjin Cement Industry Design and Research Institute Co., Ltd. jointly developed ICE Intelligent Optimum Control Platform. The platform adopted advanced control technology with model predictive control as the core, and complicated processes modeling technology with neural network, by collecting real-time production data of DCS system and combining quality data of laboratory, to realize the process optimal control of key manufacturing links in cement production process, and to achieve automatic control effects with safety, stability and optimization. This could improve output, reduce energy consumption, guarantee product quality, meet environmental protection requirements, and maximize the economic benefits of cement production enterprises.

The paper briefly introduced a type of roller presses whose roller surface installed with column nails. The operating cycle and lifetime had been improved by this type of roller press. The maintenance frequency of roller surface and entire cost were also reduced. However, with the more application of this type of roller press, some new problems had arisen. The paper focused on introducing and analyzing the failure modes of the roller surface, including the breakage and drop of nails and crack and drop of roller surface. The solutions were proposed for these issues by simulation results.

The ATOX50 raw material mill adopts the three-fans process system, and the supporting circulating fan installed power is 3 800kW, and its aerodynamic efficiency is low, resulting in relatively high power consumption of the circulating fan. In actual operation, it is basically full-load operation and becomes the most energy-consuming production process unit in cement clinker production. Therefore, after actual investigation and research, it is decided to adopt high-efficiency energy-saving fan to replace the circulating fan with the whole machine, so as to satisfy the existing production. The requirements also take into account the extreme production capacity. After the transformation, the air leakage inside the fan is greatly reduced, the resistance of the inlet and outlet pipes is reduced, and the efficiency of the whole machine is greatly improved.
