Abstract
Description
Technical Field
[0001] This utility model relates to the field of calcium powder production technology, specifically a pulverizing device for calcium powder production. Background Technology
[0002] Calcium powder, commonly known as limestone or stone powder, is mainly composed of calcium carbonate. It is weakly alkaline, sparingly soluble in water, but soluble in acid. It is a common substance on Earth, found in rocks such as aragonite, calcite, chalk, limestone, marble, and travertine. It is also a major component of animal bones or shells. Calcium powder can be classified into: heavy calcium powder, light calcium powder, activated calcium powder, flue gas desulfurization calcium powder, and ultrafine calcium carbonate. In the production of calcium powder, the raw materials need to be pulverized.
[0003] For example, utility model patent CN213669538U discloses an ore crusher for producing calcium carbonate powder, including a housing. A drive motor is fixedly connected to the right side of the back of the housing via a bracket. A shaft is welded to the output end of the drive motor. The front of the shaft passes through the housing via a bearing and extends into the inner cavity of the housing. The drive motor drives the shaft to rotate, and the shaft drives the driven gear to rotate via a drive gear, which in turn drives the crushing roller to rotate, crushing the calcium carbonate raw material. A rotary motor drives a vibrating block to rotate, which in turn drives a vibrating plate to vibrate up and down. The vibrating plate drives a screen frame to vibrate up and down, and also drives the support column to squeeze the compression spring, thus screening the crushed calcium carbonate powder to avoid the presence of large-particle calcium carbonate powder. By setting the above structure, it has the advantage of better crushing effect, solving the problem of poor crushing effect in existing crushing devices, thereby reducing the product quality of calcium carbonate.
[0004] However, when using this invention, after screening the crushed powder, it is unable to further crush the larger particles, resulting in poor performance. Utility Model Content

[0009] Beneficial effects
[0010] This utility model provides a pulverizing device for calcium powder production, which has the following beneficial effects:
[0011] 1. The material can be crushed by the rotation of the crushing roller, and the powder can be screened by the vibration of the screen plate.
