AI Technical Summary
Traditional calcium carbonate slurry mixing devices cannot achieve all-round, multi-level mixing, causing the slurry to accumulate at the edges and bottom of the mixing tank, which easily leads to clumping and affects flowability and product quality.
The material lifting component uses a rotating shaft and spiral blades to lift and circulate the bottom slurry, and the crushing roller of the extrusion component breaks up the clumps. Combined with the screen at the bottom of the mixing tank to filter out the incompletely crushed clumps, it achieves all-round mixing and screening.
It effectively prevents slurry clumping, improves mixing uniformity, ensures smooth production processes, reduces production costs, and improves product quality.
