Dewatering screen is one of the indispensable equipment in sand and gravel manufacturing. Except for sand and gravel sites, where else can the dewatering screen be used? This article takes everyone to understand the application scenarios of the dewatering screen.
1. Application of dewatering screen in potash feldspar mine
In the potash feldspar production process of potash feldspar mine, the dewatering screen is used for the dewatering operation after ball milling. The product discharged from the ball mill enters the spiral classifier for solid-liquid separation, but the product after the spiral classifier has a higher water content, which does not meet the dry pile standard. After investigation and testing, a dewatering screen is selected instead of the spiral. In the classifier, after the finished potash feldspar is dehydrated, the solid water content is no more than 15%, which fully meets the dry pile standard. Moreover, the fine sand lost by the previous spiral classifier is selected, which increases the recovery efficiency of the finished product.
2. Application of dewatering screen in barite ore
The dewatering screen is used for the secondary beneficiation of barite ore after the spiral classifier. Before selecting the barite with a higher mud content, you need to use a spiral classifier to separate the barite from the mud. However, the spiral classifier can only select barite with larger particles, and smaller ones. Then it slipped away with the mud, causing nearly 20% of the fine stone to be lost. Later, the equipment was very new, and a dewatering screen was installed after the spiral classifier so that the mud flowing out of the spiral classifier would enter the dewatering screen for secondary beneficiation. Among the mud with a daily processing capacity of 12000m3, a finished product of 2400m3 of barite was proposed. Greatly improve economic efficiency.
3. Application of dewatering screen in sand washing plant
The dewatering screen is used to separate the slag and water after the mixer in the sand washing plant. The initial investment in sand washing equipment is as high as several million, but there is no suitable equipment to sort out the sand, which is simply unprofitable production. Later, the sand field was studied and discussed, and the equipment was very new. After the mixer, a dewatering screen was installed. The sand and water were first sent to the mixer for mixing and then dewatered by the dewatering screen to separate the sand from the muddy water and select the washed sand. Moreover, the muddy water can be recycled.
4. Application of dewatering screen in vanadium mine
The dewatering screen is used in the solid-liquid separation before the filter press in the vanadium mine. A dewatering screen is installed before the filter press to discharge 75% of the vanadium ore water, and then the filter press is used for cake pressing. Through the improvement, the load of the filter press is significantly reduced and the service life of the filter cloth is extended. Moreover, the operating cost of the filter press has been reduced, and the labor cost has been reduced.
