Determine the necessity of pre-screening and ore washing
April.28,2025
When the ore has a high moisture content and a lot of powder ore, pre-screening can avoid crusher blockage and is beneficial to the operation of the crusher. However, when the ore contains a lot of water and mud, it will block the screen holes, making pre-screening ineffective.
Therefore, we should weigh the pros and cons and make careful choices. , Pre-screening of some fine particles is meaningful for reducing the load of the crusher, improving the working conditions of the crusher and saving energy. The disadvantage is that it increases the height of the plant and increases the infrastructure investment. Therefore, if the production capacity of the coarse and medium crushers is surplus, pre-screening can be ignored. When the large gyratory crusher uses full feeding, pre-screening is not set.
