AI Technical Summary

Problems solved by technology

from figure 1 It can be seen from the figure that the frequency distribution curve forms two peaks, and the fine particles smaller than 10 μm still account for nearly 40%, and these unextracted fine particles return to the mill for regrinding, making the material overgrinded. As a result, the content of fine particles smaller than 2 μm in the final product is relatively high, and its frequency distribution curve is thus formed as follows figure 2 The two peaks shown
Because of this, in the actual production process, the amount of grinding aids is large, the comprehensive power consumption of products remains high, and the final product structure is not reasonable, etc., which affects the overall operating efficiency of the enterprise.

Embodiment Construction

[0017] see image 3 , same as the prior art, the system of this embodiment consists of the raw material bin 5, the ball mill 7, the classifier and the collector according to the direction of the raw material.

[0018] The improvement to the existing technology is that the classifier in the system of this embodiment is at least two stages of multi-pole series connection, the output of the ball mill is used as the input of the first stage classifier, and the coarse material output of the previous stage classifier is used as the post-stage classifier. For the input of the first-level classifier, the coarse material output of the last-level classifier is used as the feedback input of the ball mill, and the fine material collector of the corresponding level is independently set at the fine material output port of each classifier.

[0019] exist image 3 In the present embodiment shown, the classifier is a two-stage series connection, including a first-level classifier 9 and a seco...

Abstract

A system for producing the superfine powder of heavy calcium carbonate is composed of raw material cabin, ball grinder, multi-stage classifying machine with feedback output to ball grinder, and the collectors respectively for each stage of said classifying machine.

Description

Technical field: [0001] The invention relates to a production system of heavy calcium carbonate (ie, heavy calcium) superfine powder, in particular to a production system using ball milling and superfine powder classification. Background technique: [0002] At present, in the heavy calcium superfine powder production system that uses ball milling and superfine powder classification, a closed-circuit circulation system is used. In order to ensure reasonable apex cutting and fineness requirements of the product, its cycle load often reaches more than 300%. As a result, the material has been researched in the mill, and the comprehensive power consumption of the product is relatively high, and the content of fine particles is relatively high. When this product is used as an additive in downstream manufacturers, there are defects such as poor feeding, increased usage of plastic particles, and prolonged activation time. [0003] The existing system is a single-stage classificatio...
