The design principle is: when sieving slurry containing fine-grained materials, the width of the screen surface is more important than the length or area. As long as the proper feeding and slurry concentration are maintained, multiple feeding can ensure the high-efficiency classification effect of the high-frequency vibrating fine screen.
The high-frequency vibrating fine screen uses the combined effect of continuous water flow and high-frequency vibration to realize the classification of fine-grained materials. A washing tank lined with wear-resistant rubber is arranged between the two screens. According to needs, each screen is equipped with 1 to 3 washing tanks. For example, the high-frequency vibrating fine screen manufactured by Yantai Xinhai Mining Machinery is lined with Contains patented wear-resistant rubber, wear-resistant and corrosion-resistant, and has high classification efficiency. In order to make the product on the screen that has been dehydrated by the previous screen re-slurry in the washing tank, the spray device directly sprays water to the washing tank, so that the screened material can be re-pulped in the washing tank, and the solid particles are completely overturned and formed. The agglomerated ore mud is broken up and then sieved to separate coarse and fine materials. Through multiple washing, screening, and repeated pulping, the particle size specifications required for the production of ferroalloys can be fully met.
