Analysis of Technical Transformation of Final Coal System in Coal Preparation Plant
Aiming at the problems that exist in the final coal system of coal preparation plant,such as the mixing of high sulfur and low sulfur final coal,and the mixing of some final coal products into power coal for sale,resulting in the failure of final coal products to give full play to the economic benefits,etc.,we have reasonably determined the transformation process and the transformation technology scheme in accordance with the site conditions.Mainly through the super heavy-duty cyclone to increase the processing capacity of the final coal system and to achieve high sulfur and low sulfur final coal separate sorting,at the same time,make full use of the advantages of super heavy-duty cyclone sorting efficiency,large processing capacity and other advantages of washing low sulfur final coal,increase the output of blown coal;using the original jigging system to separate high sulfur final coal,to meet the needs of the power coal allotment.After the transformation of the final coal system is completed,the final coal system of the coal preparation plant can produce about 177,500 t of blown coal,and the annual economic benefit is increased by about 28,500,000 yuan,and the technical transformation has achieved a good effect.
