Description

Technical Field

[0001] The utility model relates to the technical field of cement grinding, in particular to a cement grinding device. Background Art

[0002] Cement is a powdery hydraulic inorganic gelling material. It becomes a slurry after adding water and stirring. It can harden in the air or in water, and can firmly bond materials such as sand and stone together. Cement is one of the important building materials and is widely used in civil engineering, water conservancy and other projects. At the same time, cement blocks are common construction waste. As people pay more attention to the urban environment, the demand for the treatment of construction waste is increasing. The traditional way to crush cement blocks is to use a hammer to crush them and then transport them. The hammer crushing method not only consumes a lot of physical strength, but also easily causes debris to splash during the crushing process, posing a threat to personnel safety. In addition, the dust generated during the crushing process poses a great threat to the health of workers. The crushing efficiency is very low, and it is impossible to handle a large amount of construction waste. The cement blocks crushed by hammering are uneven in size, which is not conducive to the transportation and recycling of cement blocks. Therefore, it is necessary to crush and grind the cement blocks through a grinding device to facilitate the recycling and reuse of cement.

[0003] Most of the existing cement grinding devices are bulky and heavy, resulting in high costs and are not suitable for individual use. When the cement grinding device crushes cement blocks, a feeding port is generally opened for the convenience of adding materials. However, when the cement blocks are crushed, the open feeding port is affected by the grinding of the grinding device, and the broken cement blocks will splash, thereby causing adverse effects on the external environment and personnel safety, causing inconvenience to the cement block grinding operation and affecting the user's use.
