Description

Technical Field

[0001] This utility model relates to the field of screening and grinding technology, specifically to an integrated grinding and screening device. Background Technology

[0002] The quality of calcium hydroxide slurry produced by quicklime digestion directly affects the quality of calcium carbonate powder. High-purity calcium hydroxide slurry with uniform particle size is beneficial to improving the particle size uniformity and whiteness of the finished calcium carbonate product. Therefore, during the production of calcium hydroxide slurry, it is screened by filtration, and then the slurry with larger particle size is ground.

[0003] For example, Chinese patent CN220376997U discloses a slurry screening machine. When in use, the slurry is poured onto an ultrasonic vibrating screen. Larger particles in the slurry are retained on the screen, while the slurry and smaller particles fall through the screen into a collection box, completing the filtration and screening.

[0004] However, after screening, the device cannot automatically re-grind larger particles; therefore, it is inconvenient to grind larger particles during use.

[0005] Based on this, the present invention designs an integrated grinding and screening device to solve the above problems. Utility Model Content
