[0002] Cement raw meal is a material that is ground to a certain fineness and is made of lime raw materials, clay raw materials and a small amount of correction raw materials in proportion. Its chemical composition varies with the type of cement, quality of raw materials and fuel, production method, kiln type and other production conditions. After the raw materials of cement raw meal are proportioned, they need to be transported and the materials need to be proportioned.

[0003] In the existing cement raw material manufacturing process, different raw materials need to be weighed through a batching device to ensure the accuracy of the ratio of different raw materials. At present, the existing batching method is that the staff pours the raw materials into the mixing barrel, and then weighs the raw materials inside the mixing barrel. The weighed raw materials are poured into the mixing tank again for mixing. However, after the mixing barrel pours out the raw materials, a small amount of raw materials will still be attached to the inner wall of the mixing barrel and have not been poured out, thereby reducing the accuracy of the raw material ratio, which is not conducive to the accurate ratio of cement raw materials. Utility Model Content
