Study On Production Process Of New End Raw Coal Washing System In Coal Preparation Plant Of GJL Coal Mine

In the past two years,there will be a lot of market pressure when raw coal does not increase heat and reduce sulfur content.In order to adapt to the fluctuation of coal quality in mine mining,to stabilize the quality of products,improve the value of existing raw coal products,reduce ash and sulfur,improve the heat of products,enhance the adaptability of the market,adapt to the improvement of the quality requirements of the commodity coal and meet the requirements of the quality of the products of the product railway.Coal mine end coal washing waste,reducing ash and reducing sulfur,improving the calorific value,improving product value,providing clean coal energy to society,improving economic and social benefits of enterprises,and reducing the invalid transportation of gangue.This paper studies the production process of the new coal washing system in the coal preparation plant of GJL coal mine,and achieves the following results:(1)in-depth analysis of coal quality data,accurate calculation of various process links to provide reliable guarantee for equipment selection,the process can adapt to various changes in the actual production needs.(2)according to the coal quality characteristics of the washing raw coal in the factory,the overall situation of coal washing and processing in the nearby mining area has been considered as a whole,and the technological process has been designed.The process is simple and practical,the control of the process is flexible and smooth,the quality control is efficient and simple.(3)the equipment selection fully considers the compatibility,universality and consistency with the existing equipment.The recommended equipment has the characteristics of strong reliability,high stability,strong applicability,advanced technology,overall matching,high efficiency and low consumption and strong operability.The operation and maintenance of the equipment are convenient and flexible,and the operation cost and maintenance cost are low during the operation cycle.(4)the process and link setting is advanced,reasonable,reliable and highly efficient,and the design of coal mud water system is perfect,which can ensure the closed circulation of water washing,reach zero discharge and meet the requirements of environmental protection.(5)with high automation and precise control and adjustment system,the whole process monitoring and monitoring can be realized.The washing and processing of the raw coal in Gao Jia Liang colliery is in line with the national coal industry policy.When the sulfur content of the coal in some coal seams in Kao Jia Liang coal mine is high,it is necessary to wash and reduce sulfur to meet the policy needs of the national environmental protection and sustainable development strategy.After the raw coal washing and processing,the added value of the product is large,and the quality is stable.It can establish good supply relationship with the users and improve the economic efficiency of the enterprises to a large extent.
