Application of Crushing Process Transformation in a Certain Iron Ore Beneficiation Plant in Xinjiang
The crushing section of a magnetite ore beneficiation plant in Xinjiang adopts a three-stage closed circuit crushing and dry magnetic pre selection process,which has the problem of high cyclic load in the crushing system during the production process.To achieve the goal of reducing crushing cycle time,increasing ore crushing volume,reducing grinding particle size,increasing grinding processing capacity and grinding efficiency,it is necessary to optimize the crushing process in the benefici-ation plant.Increase the aperture of the original circular vibrating screen to reduce the fine crushing cycle load;After the origi-nal dry magnetic pre selection,high-pressure roller grinding and vibrating screen are added to reduce the particle size of the grinding material,resulting in more crushing and less grinding;Add a magnetic drum in front of the high-pressure roller sys-tem for waste disposal,allowing for early disposal of gangue minerals.After the optimization of the crushing process,the amount of crushing has increased,the particle size of grinding has decreased,the grade of grinding has been improved,and the production capacity has also been increased.
