Embodiment Construction

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

[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] In the present embodiment shown in Figure 3, the classifier is a two-stage series connection, including a first-stage polarizer 9 and a second-stag...

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...
