A continuous batching and feeding integrated system for cement production

Abstract

The invention provides a continuous batching and feeding integrated system for cement production, which includes a conveying unit, four raw meal batching stations and a feed control unit, and the feed control unit is used to synchronously control the four raw meal batching stations. Intermittent feeding and discharging ensure the smooth progress of the crushing process of materials entering the raw material batching station and avoid material blockage caused by material accumulation; use the screening pre-crushing unit, secondary crushing components and crushing The unit performs three-stage crushing on the material, so that the particle size consistency of the material outflow is improved, and the weight of the outflow material per unit time is guaranteed to be equal; the use of the split-type design of the hopper unit and the vibration motor prevents the material from accumulating on the inner surface of the lower hopper, which affects the discharge. The effect is to ensure that the quality of the falling materials per unit area is equal during continuous discharge, so as to ensure that the final proportion meets the process requirements, improve the yield of cement clinker, reduce the occurrence of clogging, and improve production efficiency.

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
