Aggregates Washing Water Consumption


Aggregate washing is the process of cleaning and removing impurities in sand and gravel. It mainly uses freshwater to wash and dilute and remove impurities such as soil and stones contained in the sand and gravel. The more mud in the gravel, the greater the water consumption. So the aggregate washing water consumption has become a concern for many customers. How much water is needed to wash a ton of aggregate?

In the actual process of aggregate washing, the water consumption needs to be determined according to the processing capacity and the soil content of the material. And for different types of sand washing equipment, water consumption also varies greatly. Excessive water supply will cause rapid water flow and excessive loss of fine sand. If the mud content of the material is too large, the correct method is to increase the number of sand washing machines, thereby increasing the number of sand washing and water consumption, rather than directly increasing the amount of water on a sand washing machine. The ratio of sand to water in the spiral sand washer is about 1:1 or 1:1.5, while the ratio of sand to water in the bucket sand washer is about 2:1 or 4:3. It can be get from this ratio that the bucket sand washer is more water-saving and the spiral sand washer is more water-consuming. Of course, this is not fixed, just as a data reference. The specific water consumption needs to be determined according to factors such as the particle size, mud content, powder content, and processing capacity of the sand.

Taking LZZG spiral sand washer as a reference, the processing capacity of LSX920 is 30-80t/h, the water consumption is 50-120t/h. The processing capacity of LSX1120 is 100-150t/h, the water consumption is 120-200t/h. Generally, a large amount of water is required for aggregate cleaning, so the sand washing production line should be set close to the water source to facilitate the nearest water intake.
