Description

Technical Field

[0001] This utility model relates to the field of calcium carbonate processing technology, and in particular to a lightweight calcium carbonate base material grinding mill. Background Technology

[0002] With the rapid development of my country's economy, light calcium carbonate, as an important non-metallic mineral material, has been widely used in various industries such as plastics, coatings, rubber, papermaking, pharmaceuticals, and food. Light calcium carbonate possesses excellent dispersibility, filling properties, and stability, effectively improving product quality and performance. To meet market demand, the production technology of light calcium carbonate is constantly being optimized. As a key piece of equipment in the production process, the performance of the grinding mill has a crucial impact on product quality. A search revealed Chinese patent CN218654830U, which discloses a light calcium carbonate bottom material grinding mill, belonging to the field of calcium carbonate processing technology. The mill includes a main body, inside which, from top to bottom, are arranged an inlet, a crushing chamber, a feeding channel, a grinding chamber, and an outlet. A cover plate completely covers the top wall of the main body. The inlet is located below the cover plate, with both ends connected to the inner side wall of the main body. The crushing chamber contains two cooperating crushing rollers. The grinding chamber contains a grinding cone driven by a motor. A grinding plate with the same shape as the bottom surface of the grinding cone is located inside the main body and below the grinding cone. This light calcium carbonate bottom material grinding mill, with its crushing chamber, feeding channel, grinding chamber, and collection box, can effectively grind the bottom material, solving the problem of unsatisfactory grinding effects in existing devices.

[0003] The light calcium carbonate base material grinding mill in the aforementioned patent has the following shortcomings: When the equipment is in use, the qualified base material is collected through the first collection box, and the unqualified base material is collected through the second collection box. The user needs to put the base material in the second collection box back into the equipment for grinding again, which is inconvenient to use and increases the user's workload. Therefore, a light calcium carbonate base material grinding mill was designed to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a lightweight calcium carbonate base material grinding mill.
