Why we need Slurry Pumps in the Coal Industry
When people get coal directly from the mining area, most of the mined materials are of uneven quality and may be mixed with other ingredients, so we need do another processing. Which is always called coal preparation. It is the process of sorting good coal that meets the quality requirements of users from raw materials.
In terms of technology, coal preparation can be divided into dry coal separation and wet coal separation. Dry separation includes separation by air, screening, and manual separation. Wet coal separation includes hydraulic screening and heavy-medium separation. And coal washing is an industrial process that removes impurities in raw coal, or classifies high-quality coal from inferior coal.
In the coal preparation plant the raw coal will pass a complete set of process system, which is mainly composed of coal receiving system, raw coal preparation system, separation system, dehydration and demineralization system, slime water system and product transportation system. although there may be slight difference in different regions , the Slurry pumps used in this process are for the below purpose
1.Offer the water to the washing system, which is mainly used to wash the magnet powder medium that is together with the coal block and as system water, the conveying the ground water or leaked slurry to the thin medium barrel to finish the water circulation
2.Transfer the mixed slurry composed of coal and qualified medium to different process facilities to complete the separation.
What need to be alert here is that, during the processing,the slurry is changing always, so the order to maximize the advantages. In actual selection, pumps should be picked out according to specific working conditions such as slurry concentration particle composition and the pressure.
