Application of the 3510 flip-flop screen at Yangquan No.1 Mine's Coal Preparation Plant

In order to maintain and improve product quality of the plant, the scheme for washing unsized raw coal after extraction of coal fines with flip-flop screen is proposed following analysis of the raw coal property. Practice shows that when used for dry screening of raw coal at a size of 3 mm, the efficiency of the screen is 67.75%, which can fully meet the in-depth dry screening requirement. The use of the screen has led to reduction of moisture, increase of calorific value, and improved quality of products.
