Airflow purification production line special for sericite

Abstract

The invention discloses an airflow purification production line special for sericite. The production line comprises a grinding system, a purification system, a grading system, a dust removing system, an iron removing system and an electric control system. By adequately considering a plurality of important links during the production of sericite, the air purification production line special for sericite disclosed by the invention is capable of well guaranteeing the stability of the device and the quality of the products.

Description

technical field [0001] The invention relates to the technical field of sericite powder preparation, in particular to a special airflow purification production line for sericite powder. Background technique [0002] Sericite powder is a functional filler that was discovered and used in coatings and paints in the past 20 years. Now it has been developed and used in cosmetics, electronic insulation boards, refractory fiberboards and other fields. But so far, there is no dedicated production line in sericite production, so each sericite manufacturer can only purchase some equipment and accessories based on experience to install and debug by themselves. Obviously, when such a method is adopted for production, the production equipment is prone to problems, and the production quality cannot be guaranteed. Specifically, the following problems are prone to occur: 1. The grading effect is poor, resulting in uneven product thickness, affecting the stability of product particle size, a...

AI Technical Summary

Problems solved by technology

Specifically, the following problems are prone to occur: 1. The grading effect is poor, resulting in uneven product thickness and affecting the stability of product particle size. The residue on the 400-mesh sieve is about 5%, so that the product can only be used for low-end products.

2. The grading is not clean, the iron content is as high as 2.4% or more, and the impurity content is more than 1.78%, which seriously affects the product quality and cannot be used in the electronic circuit board and cosmetics industries

3. The purity of the product is poor, because sericite ore is a quartz-associated ore, improving the performance of sericite powder can only remove the quartz content, and the separation of quartz by grading equipment is poor, the content of aluminum oxide is up to 18%, and the content of The silicon content is as high as 68%, so that the purity of sericite is low

4. Due to the strong pressure production of the equipment, the excess gas of the blower will be forcibly ejected along the pipeline and some unsealed gaps, thereby generating dust, which makes the dust pollution in the workshop serious and affects the health of workers

5. The specifications of the production products are relatively single, and it is impossible to realize the simultaneous output of multiple products, which wastes a lot of sericite raw ore, electricity costs and labor
