Understanding The Wash Plant Process

After the filter pressing process, clear water enters to realize the recycling of clean water and create zero discharge of the whole process. ● Stones and sand are screened, washed and dewatered in the plant while the muddy water can be recycled use. There are plenty of advantages to this entire process.

PQ University Lesson 9- Washing Classifying :

10-09-2015  Washing and classifying of aggregate can be considered in two parts, depending on the size range of material. Coarse material: Generally above 3/8 in. (sometimes split at 1/4 in. or #4 mesh). In the washing process it usually is desired to remove foreign, objectionable material, including fine particles. Fine aggregate: From 3/8 in. and smaller.

How much water does that wash-plant consume?

08-07-2012  So presumably that’s 20 tons of water per hour (of wash plant operation) leaving the mine site (5% of 400 tons/hour). Or, converting that to gallons (at 8.33 lbs of water per gallon, which translates to 240 gallons/ton) about 4802 gallons of water per hour of operating the wash plant. Or 115,246 gallons of water per day
