Creating the"ningmei special excellent"brand for clean coal system process renovation
The cleaned coal products from the Zaoquan Coal Washing Plant in the Washing and Selection Center have the characteristics of low ash,low sulfur,and low volatility.In the past,cleaned coal was mainly sent to coal to oil and coal chemical industry for fuel coal,but the deep utilization of the products has not been achieved.By exploring the market and tapping the inherent potential of the products,the Xinzaoquan Coal Washing Plant has undergone technological transformation and internal tapping,producing high-quality raw coal that can be used as coking coal.The original process flow of Zaoquan Coal Washing Plant can only produce"Ningmei Special You-3"clean coal products by improving operational skills and reasonably matching mine raw coal.In order to improve economic benefits and achieve brand benefits,necessary process flow transformation must be carried out to achieve the production of"Ningmei Special You-2"or"Ningmei Special You-1"clean coal products.Combined with the original process flow and coal quality characteristics,the transformation scheme is proposed to change the two product process flow of thefine coal system to the three product process flow,and separate the middling coal and coarse slime from the original clean coal product.The newly added middling coal and the coarse slime of the original system after the transformation are mixed into the final product,which can reduce the ash content of the clean coal product and meet the process requirements of the final coal system for producing super fine series of clean coal products.
