More Information
Summary:The invention discloses a paste preparation method based on vacuum filtration thickening and dehydrating and a preparation system. The preparation system comprises a vacuum filter, a mill tailings conveying belt, a cement bin, a micro-powder scale, a horizontal mixer and a vertical mixer. The vacuum filter is used for vacuum-filtering mill tailings as a filter cake. The mill tailings conveying belt is used for conveying the filter cake to the horizontal mixer. The micro-powder scale is used for quantitatively conveying a cementing material in the cement bin to the horizontal mixer. The discharging end of the horizontal mixer is connected with the feeding end of the vertical mixer. The preparation method is capable of processing all mill tailings and thickening by using a vacuum filtrationmode, and overcoming problems in a current paste filling technology that a rake is easily pressed, and the mill tailings is graded and the like, and has the characteristics of good thickening effect,good continuity, and effec
