Raw material batching station with stable batching function

Abstract

The invention provides a raw material batching station with a stable batching function. The raw material batching station comprises a hopper unit, pre-crushing units and secondary crushing assemblies.When materials are located in a primary screening and crushing space, the screening and pre-crushing units are used for lifting and screening the materials, so that the primary crushing effect is achieved; and when the materials are conveyed to secondary crushing spaces, the secondary crushing assemblies are used in cooperation with concave-convex tracks arranged on screening mounting frames in the descending process, large materials are subjected to secondary crushing multiple times, crushing units arranged below the secondary crushing spaces are used for crushing the materials which are notcrushed in a tertiary mode, and it is guaranteed that the particle size of the flowing-out material is uniform and consistent. Due to the split design of the hopper unit and a vibration motor on oneside of the hopper, the problem of material accumulation is effectively solved, it is guaranteed that the mass of the materials falling per unit area is equal during continuous discharging, thus, it is guaranteed that the final proportion meets the technological requirement, the yield of cement clinker is increased, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of cement production equipment, in particular to a raw material batching station with a stable batching function. 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] Chinese invention patent 202010306565.8 discloses that the invention relates to a hopper anti-blocking and anti-accumulation system, including a hopper, a frame is provided on each side of the inner wall of the hopper, and several vertical planes on the inner wall of the hopper are arranged between one side of the frame and...

AI Technical Summary

Problems solved by technology

[0004] However, in this technical solution, the anti-blocking effect of large limestone and clay mixed materials is poor, which affects the final material ratio, makes the kiln raw meal stability coefficient (KFUI) seriously high, and adversely affects the calcination of the kiln. , the strength of the clinker out of the kiln is unstable, which affects 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
