焦炭的细磨是在干磨球磨机和棒磨机中进行的。细磨过程的调节,要在给定研磨细度条件下保证磨机的最大生产率。焦炭的研磨质量按磨碎产品中粒级为0.08毫米的含量(阳极车间为65±5％,电极厂为85±5％)进行控制。运行实验表明:手动控制过程时,控制粒级含量的均方误差为6.3～8.2到20～23％。电极工业和铝工业的各企业里,在推广声 Fine coke grinding is carried out in a dry grinding mill and a rod mill. Adjustment of fine grinding process, to ensure that the maximum mill production rate given the grinding fineness. The grinding quality of the coke is controlled by the grain size of 0.08 mm in the ground product (65 ± 5% for the anode plant and 85 ± 5% for the electrode plant). The running experiments show that the mean square error of control grain size is 6.3 ~ 8.2 ~ 20 ~ 23% when the manual control process is used. Electrode industry and the aluminum industry in various enterprises, the promotion of sound
