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

Embodiment 1

[0051] Such as figure 1 , 14 As shown, a raw material batching station with stable batching function, including:

[0052] Hopper unit 2; the hopper unit 2 is an upper and lower split structure, which includes an upper hopper 21 and a lower hopper 22; the lower hopper 22 is hoisted below the upper hopper 21 through a flexible part 23; the upper hopper 21 The top is provided with a feed hopper 26; wherein the flexible member 23 can be selected from nylon belts, belts, chains, etc., preferably chains; Dust is prone to occur at the place and causes the problem of poor working environment on site; wherein the inner wall of the lower hopper 22 is provided with a polyethylene plate 25, which reduces the friction of the inner wall of the lower hopper, improves the smoothness of the passage of materials, and avoids the phenomenon of material blockage;

[0053] Two groups of screening pre-crushing units 3 symmetrically arranged in the upper hopper 21, such as image 3 , 4 A primary ...

Abstract

The invention provides a raw material batching station with stable batching function, which includes a hopper unit, a pre-crushing unit and a secondary crushing component. Primary crushing effect: When the material is transferred to the secondary crushing space, the secondary crushing component is used to cooperate with the screening of the concave and convex tracks set on the mounting frame during the descending process, so that the bulk material is crushed by the secondary crushing multiple times. The crushing unit below the crushing space crushes the uncrushed material three times to ensure that the particle size of the outflowing material is uniform; the split-type hopper unit and the vibration motor on one side of the hopper effectively solve the problem of material accumulation. Ensure that the quality of materials falling per unit area is equal during continuous discharge, so as to ensure that the final ratio meets the process requirements, improve the yield of cement clinker, and improve production efficiency.

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...
