摘要
小型顶装焦炉利用原有生产工艺的破碎机对贫瘦煤进行预粉碎到3 mm以下,分别测试了六次焦炭质量,结果表明在相同配合比例下对贫瘦煤预粉碎可以提高焦炭抗碎强度2%左右;在保持焦炭抗碎强度前提下可以多配入贫瘦煤5%～7%,耐磨强度略有降低。
Small top-loading oven using the original production process of the lean coal crusher to crush the pre-3 mm below the quality of coke were tested six times,the results showed that the coke mechanical strength can improve 2% at the same proportion with the lean pre-grinding process.In maintaining the premise of crushing strength of coke can be blended with lean coal more than 5% to 7%,but abrasion resistance slightly lowered.
