Description

Technical Field

[0001] The utility model relates to the technical field of mineral powder external admixture devices, and particularly relates to a device for evenly externally admixing mineral powder in a cement mill. Background Art

[0002] The device for evenly externally admixing mineral powder in a cement mill is a device used to directly admix mineral powder into the finished cement. This device can increase the volume of cement without affecting the quality of the cement, thereby reducing the cost of the cement. During the operation, according to the different admixing times of the mineral powder, the external admixture can be divided into early external admixture and late external admixture. Early external admixture means grinding the mineral powder and clinker together into cement clinker, while late external admixture means admixing the mineral powder into the product made into cement. When the device for evenly externally admixing mineral powder in a cement mill conducts external admixture, since the external admixture port is static, the mineral powder will accumulate at a certain place when added, which is not easy to mix quickly, resulting in low efficiency and having certain deficiencies.
