Application Industry and Economic Reliability Analysis of High Frequency Dehydration Vibration Screen

The problems existing in the slag water separation process or tailings treatment in the beneficiation plant are discussed. The economy and reliability of using high-frequency dewatering screens in the slag water separation process are discussed. This not only solves the problems of waste of mineral resources and high investment in the beneficiation plant, but also helps to achieve resource recovery and utilization in the production of the beneficiation plant. It not only realizes the investment strategy of low investment and high return, but also responds to the government's energy-saving and environmental protection policies, enabling enterprises to achieve a win-win situation.

 

 

1, The application of potassium feldspar ore for dehydration after ball milling

In the production of non-metallic potassium feldspar in a building materials factory in Quanzhou, Fujian, the process involves a ball mill discharging the material and then entering a spiral separator for slag water separation. However, after using a spiral separator for slag water separation, the moisture content of the finished material is too high and cannot be stacked dry. After investigation and experimentation, our company's high-frequency dewatering screen was chosen to replace the spiral separator. The water content of the finished potassium feldspar after dehydration and separation through the high-frequency dewatering screen was less than 15%, fully achieving the dry pile effect. In addition, the fine sand lost during the original use of the spiral separator was also selected, which increased the recovery rate of the finished product. The economic benefits brought by the high-frequency dewatering screen far exceeded those of the original spiral separator.

2, The application of barite ore for secondary beneficiation after spiral separator

In a certain beneficiation plant in Liuzhou, Guangxi, due to the high mud content of barite, it is necessary to first use a spiral separator to mix and wash the mud with water, and then separate the finished barite and mud water. The disadvantage of using a spiral separator for beneficiation is that it can only select large particles of barite ore, and about 20% of the fine ore flows with the mud water, which makes the barite ore unable to be fully recovered and causes resource waste. Later, with equipment updates, a high-frequency dewatering screen was installed behind the spiral separator to allow the effluent to be further processed using the high-frequency dewatering screen. From a daily processing of 12000 cubic meters of sludge, 2400 cubic meters of barite can be extracted, greatly improving economic benefits.

3, Application in the sand washing industry for slag water separation after mixers

A sand and gravel factory in Yulin, Shaanxi Province invested several million yuan in sand washing equipment before, but there was no suitable equipment to select sand, and the benefits could not be generated. Later on, equipment updates were carried out by adding a high-frequency dewatering screen after the mixer. The sand and water were first mixed in the mixer, and then the high-frequency dewatering screen was used to separate the sand and mud water. The cleaned sand was selected, and after the mud water settled, the water was recycled for use. The sand also met the requirements of the construction manufacturer, and economic benefits were immediately generated.

4, The application of vanadium ore for slag water separation in front of filter press

A vanadium mine in Changsha, Hunan Province used a pressure filter to separate slag and water. Due to the high density, large particle size, and strong acidity of vanadium ore, a large model of pressure filter was used, resulting in high investment, high energy consumption, fast wear and corrosion, and short service life of filter cloth during production and operation. During the technical renovation, a high-frequency dewatering screen is installed in front of the filter press. About 70% of the vanadium ore is first discharged using the high-frequency dewatering screen, and the remaining small amount of vanadium ore is then processed by pressing cakes using the filter press. After the process improvement, the load of the filter press was significantly reduced, the area of the filter press used was reduced, the service life of the filter cloth was extended, and the operating cost of the filter press was reduced, as well as the labor cost.

 

 

5, Application of coal washing plants

In the coal washing process, it is necessary to add water to clean the coal slurry and soil on the raw coal, and then separate the washed coal and mud water. High frequency dewatering screens can be used to continuously discharge the washed finished coal, making the finished coal and mud water automatically separate, and allowing continuous production and operation.
