Abstract
Description
Technical Field
[0001] This utility model relates to the field of ball mills, and more specifically, to a raw ore ball mill for calcium carbonate production. Background Technology
[0002] Calcium carbonate is an inorganic compound. During processing, the raw ore of calcium carbonate is ground and pulverized into powder using a ball mill. However, in existing ball mills, the calcium carbonate powder tends to adhere to the inner surface of the mill during grinding. The ball mill's cylinder is typically cylindrical, making it difficult for workers to clean the inside and affecting the grinding efficiency.
[0003] Application CN 221693818 U relates to the field of calcium carbonate ore processing technology and discloses a calcium carbonate ore ball milling device that is easy to clean. The device includes a ball mill and support bases. The two ends of the ball mill are rotatably connected to the inner sides of two sets of support bases. A cleaning mechanism is provided on one side of the ball mill, and a cooling mechanism is provided on the top of the ball mill. The cleaning mechanism includes a support frame, a hydraulic cylinder, a connecting rod, a push plate, and cleaning sponges. The support frame is welded to the outer side of one set of support bases, the hydraulic cylinder is located on the outer side of the support frame, one end of the connecting rod is fixedly connected to the output end of the hydraulic cylinder, and the end of the connecting rod away from the hydraulic cylinder is rotatably connected to the outer side of the push plate. Two sets of cleaning sponges are adhered to the inner side of the push plate. This easy-to-clean calcium carbonate ore ball milling device allows the ball mill to easily perform self-cleaning by adjusting the position of the push plate, which in turn drives the cleaning sponges to brush the calcium carbonate powder inside the ball mill. This makes the calcium carbonate ore ball milling device convenient to use.
[0004] The aforementioned structure lacks a fixed support cylinder connecting the mill cylinder and the water outlet pipe, resulting in a high drainage position that cannot drain water from the lowest point, leading to poor adaptability. Furthermore, the cleaning structure is not conducive to independent installation and control for telescopic adjustment, and the complex structure affects the flushing and cleaning effect, which needs to be improved. Utility Model Content
[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a raw ore ball mill for calcium carbonate production. The mill is connected to a support ring and a grinding cylinder via a support cylinder on the bottom plate. Combined with a water outlet pipe on the side, it can support rotation and facilitate drainage from the lowest point, ensuring stability and efficiency. Furthermore, an adjusting pipe is installed via a fixed pipe, connecting to an annular pipe and a cleaning brush. Combined with surface nozzles and notches, the brush can be individually extended and retracted for water spray cleaning, which is convenient, quick, avoids mutual interference, is simple, efficient, and easy to use.
