Continuous batching and feeding integrated system for cement production

Abstract

The invention provides a continuous batching and feeding integrated system for cement production. The continuous batching and feeding integrated system comprises a conveying unit, four raw material batching stations and a feeding control unit. The feeding control unit is used for synchronously controlling intermittent feeding and discharging of the four raw material batching stations, it is guaranteed that the crushing process of materials entering the raw material batching stations is smoothly carried out, and material blockage caused by material accumulation is avoided; a screening pre-crushing unit, a secondary crushing assembly and a crushing unit in the raw material batching stations are used for carrying out three-stage crushing on materials, so that the size consistency of particlesflowing out of the materials is improved, and it is guaranteed that the weights of the materials flowing out in unit time are equal; and by means of a hopper unit and a vibration motor which are designed in a split mode, materials are prevented from being accumulated on the inner surface of a discharging hopper, the discharging effect is prevented from being affected, it is guaranteed that the mass of the materials falling per unit area is equal during continuous discharging, and therefore it is guaranteed that the final proportion meets the technological requirement, the yield of cement clinker is increased, blocking is reduced, and production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of cement production equipment, in particular to a continuous batching and feeding integrated system for cement production. Background technique [0002] The main production process of cement is crushing, homogenization, blending, and grinding to complete the production of raw meal powder; the raw meal powder is calcined to obtain slaked lime. Among them, in the blending process, limestone, iron powder, shale, clay, etc. are blended in a certain proportion and then transferred to the ball mill for grinding. The blending ratio has an important impact on the quality of the subsequent cement. [0003] The batching and feeding system of the existing blending process is that several feeding bins transfer the materials to the conveyor belt at the same time, and the conveyor belt transfers the materials on the conveyor belt to the ball milling process. During feeding, other material bins continue to feed materials...

AI Technical Summary

Problems solved by technology

[0003] The batching and feeding system of the existing blending process is that several feeding bins transfer the materials to the conveyor belt at the same time, and the conveyor belt transfers the materials on the conveyor belt to the ball milling process. During feeding, other material bins continue to feed materials, resulting in the final ratio unable to meet the process requirements, so that the kiln raw material stability coefficient (KFUI) is seriously high, which has an adverse effect on the calcination of the kiln, and the strength of the kiln clinker is unstable. , affecting the consumption of cement clinker, and when the silo is blocked, it is difficult to clean up, the workload is heavy, and the shutdown affects production
