AI Technical Summary

⚠Technical Problem

The existing vertical cement raw material mill spraying structure results in poor material dispersion, causing concentrated falling and affecting grinding quality and efficiency.

⚗Method used

A material spraying device was designed, which includes a feeding pipe, a first disc, and a second disc. The second disc rotates and achieves uniform distribution of raw materials through a long material trough and baffles. Combined with high-pressure gas-assisted diffusion, it ensures that the raw materials fall evenly in the radial and circumferential directions.

🎯Benefits of technology

It improves the uniformity and flowability of raw materials in the raw material mill, enhances grinding quality and efficiency, avoids raw material accumulation, and achieves more efficient raw material processing.

Abstract

The present application relates to the technical field of bulk material structure, and particularly relates to a vertical cement raw material mill spraying material device, which comprises a feeding pipe, a first disc and a second disc, the first disc and the second disc are arranged in an up-down distribution, and the first disc and the second disc are coaxially arranged, a space between the first disc and the second disc is set as a material uniformizing space, the feeding pipe is vertically installed on the top of the first disc and is used for feeding material into the material uniformizing space, a baffle ring is arranged at the edge position of the second disc, and the first disc is in contact with the baffle ring; the second disc is designed to rotate and spread the raw material outward, combined with the annular distribution of the plurality of bulk material long groove plates, so that the raw material is not only evenly scattered in the circumferential direction, but also achieves more extensive distribution in the radial direction, and the "planar" falling mode greatly improves the distribution uniformity of the raw material in the raw material mill, which is beneficial to improve the grinding quality and efficiency.
