Study on the Improvement of Fine Deep Screening Process for Steam Coal Raw Coal
In order to solve the problems of large error and low efficiency of deep fine screening of steam coal raw coal,the deep fine screening process of steam coal raw coal has been improved,and its effectiveness has been tested.The results show that under the improved process,the content of fine and deep screening mismatches of steam coal raw coal is at least 3.5%,and the screening efficiency is about 83%.This shows that this method improves the shortcomings of the traditional screening process,reduces the content of screening mismatches,and improves the screening efficiency,which is conducive to promoting the development of coal preparation production technology and meeting the market demand for coal consumption.
