Description

Technical Field

[0002] Limestone's main component is calcium carbonate. Lime and limestone are widely used as building materials and industrial raw materials. Limestone can be directly processed into stone and burned into quicklime. Quicklime absorbs moisture or adds water to become slaked lime, also known as calcium hydroxide. Slaked lime is then mixed into lime slurry and lime paste, which are used as coating materials and brick and tile adhesives.

The grinding core, grinding seat and bracket are all arranged in the grinding chamber. The grinding seat is an annular structure, which is fixed to the bottom of the grinding chamber. The grinding core is arranged on the bracket, and a slider is provided on the side of the bracket. The slider is installed on the wall of the grinding chamber. The annular inner groove of the grinding seat is set to a cone. The grinding core cooperates with the conical inner groove, and a turntable is provided on the bracket, which is fixedly connected to the grinding core through a rotating shaft. When in use, the limestone to be ground is put into the guide groove of the guide block and enters the grinding chamber through the feed trough. The motor of the turntable is controlled by the controller to drive it to rotate, and then the grinding core is driven to rotate through the rotating shaft. The grinding core and the grinding seat rotate relative to each other, thereby grinding the limestone between the grinding wall and the gap of the grinding core. The ground limestone powder falls along the gap under the action of gravity and finally falls on the bottom of the grinding chamber. After being collected for a certain period of time, it is taken out in batches through the discharge trough.
