摘要:
针对海口磷业有限公司选矿厂碎矿和磨矿作业综合电耗高、磨矿作业台时处理量低等问题,提出了可行的技术改造方案. 根据选矿厂“多碎少磨”的技术原则,优化破碎作业工艺流程,调整各段作业破碎比和筛网规格,降低破碎粉矿产品粒度,从而提高磨机单位生产能力,提高了选矿厂的产能. 通过技术改造,实现了在保持磨矿最终产品细度-0.074 mm粒级含量达到88%以上的前提下,磨矿台时处理能力由137 t/h提高到168 t/h,并将碎矿、磨矿作业综合电耗由18.89 kW·h/t降低到15.95 kW·h/t.
Abstract:
Aimed at the low grinding productivity and high electrical input in particle size reduction operation (including crushing and grinding) at Haikou phosphate plant, we proposed feasible technical modification methods. Based on the technical principle of more crushing and less grinding to save energy consumption, the particle size of crushed product was decreased by optimizing crushing operation process, and the performance of grinding was improved by controlling the crushing ratio and screen size at every operation step. After technical modification, the productivity of grinding processing increases from 137 t/h to 168 t/h, while the mean power consumption of crushing and grinding collophanite reduces from 18.89 kW·h/t to 15.95 kW·h/t when the content of particle size -0.074 mm in the final product is more than 88%.
