Description

Technical Field

[0001] The utility model relates to the technical field of powder grinding devices, in particular to a light calcium carbonate powder grinding device. Background Technique

[0002] Light calcium carbonate is prepared by calcining raw materials such as limestone to produce lime and carbon dioxide, then adding water to digest the lime to form lime milk, then introducing carbon dioxide to carbonize the lime milk to form calcium carbonate precipitate, and finally dehydrating, drying and pulverizing by a lime pulverizer. It is a widely used chemical substance, mainly used as a filler and thickener in industries such as plastics, rubber, coatings, and papermaking.

[0003] In the Chinese utility model patent application number: CN202121954757.6, a light calcium carbonate pulverizer is disclosed. Through the setting of the grinding groove and grinding balls on the inner side of the outer shell, the driving mechanism can drive the grinding balls to rotate inside the grinding groove, and with the setting of the inner grinding head and the outer grinding head, the grinding effect of calcium carbonate blocks during processing can be ensured, solving the problem that the existing device has poor grinding effect on calcium carbonate blocks, resulting in low efficiency.

[0004] Although the above patent realizes the function of grinding light calcium carbonate, however, the above patent has the following disadvantages in use: the above light calcium carbonate pulverizer does not set a sieve plate vibration assembly during use, which is not conducive to the screening of calcium carbonate. During the screening process of calcium carbonate, it is easy to cause blockage of the sieve plate layer, which in turn affects the subsequent screening effect and is not convenient to use. Therefore, we propose a light calcium carbonate powder grinding device. Content of the Utility Model

At the same time, the rotating shaft 17 can drive the rotating rod 14 to rotate, so as to further grind the light calcium carbonate through the second grinding heads 10. Through the setting of the sieve plate 13, the ground light calcium carbonate can be screened. The rotation of the transmission shaft 11 drives the knocking rods 20 to rotate, so as to knock the sieve plate 13 through the rubber balls to prevent blockage.

[0026] Furthermore, a feeding frame 5 is opened at the top of the housing 1, and a collecting frame 12 is slidably connected inside the housing 1. Through the setting of the collecting frame 12, it is convenient to collect and process the screened light calcium carbonate.
