Description

Technical Field

[0001] This utility model relates to the field of horizontal sand mills for processing modified heavy calcium carbonate for coatings, and more specifically, to horizontal sand mills for processing modified heavy calcium carbonate for coatings. Background Technology

[0002] A horizontal sand mill uses a pump to feed a solid-liquid mixture, which has been pre-dispersed and wetted by a mixer, into the mill body. The material and the grinding media inside the mill body are agitated by a high-speed rotating disperser, resulting in stronger collisions, friction, and shearing between the solid particles in the material and the grinding media, thereby accelerating the grinding of particles and dispersing aggregates. In existing conventional horizontal sand mills, such as the one disclosed in patent publication number CN220759439U, a horizontal sand mill with a stepped dispersion disc is included. This includes a sand mill tank, with a horizontal sand mill body fixedly connected to one end of the tank. A cooling water tank is located at the bottom center of the horizontal sand mill body, and a semiconductor cooling chip is fixedly connected to the front center of the cooling water tank. Flow pipes are fixedly connected to both ends of the cooling water tank and the sand mill tank. Support legs are fixedly connected to the four corners of the bottom of the horizontal sand mill body, and casters are fixedly connected to the bottom of the threaded rod. With the above structure, the main body of the horizontal sand mill is started, causing its rotating rod to rotate. After rotation, it drives the first and second step dispersion discs to rotate. The step-decreasing method allows the material to be subjected to different dispersion forces during processing. The movement mode of the grinding zircon beads and coating in the horizontal sand mill will also change multiple times, increasing the processing effect of the sand mill.

[0003] The aforementioned patents employ a decreasing placement grinding method, which complicates the grinding mechanism, increases costs, and makes assembly and disassembly inconvenient. The sand mill has a simple and complex structure, resulting in high mechanical costs. Utility Model Content
