Embodiment 1

[0021] A mica powder dry powder granulation process comprises the following steps:

[0022] S1, put the mica powder into the pulverizer for pulverization;

[0023] S2. Preparation of mica powder screening equipment: select a shell, connect a hose to both sides of the shell, and install two vertical filters inside the shell, and the filters are parallel to each other , and the apertures between the filters are not the same;

[0024] S3. Install the induced draft fan: connect the hose close to the filter screen with smaller aperture to the inlet end of the induced draft fan;

[0025] S4. Use the mica powder screening equipment and the induced draft fan to attract the pulverized mica powder in the pulverizer. When attracting, extend the hose away from the induced draft fan into the inside of the pulverizer. After the suction is completed, collect it between the two filter screens mica powder, after the mica powder inside the pulverizer is completely absorbed, connect the inlet ...

Abstract

The invention discloses a dry powder granulation process for mica powder. The process includes the steps of: S1, putting mica powder into a crusher for crushing treatment, S2, preparation of mica powder screening equipment; S3, installation of an induced draft fan; S4, screening treatment of mica powder; S5, ball-milling treatment of the mica powder in S4 in a ball mill to obtain dry mica powder;and S6, granulation treatment on the dry mica powder by a dry powder roller granulator, thus obtaining dry mica powder granules. The dry powder granulation process for mica powder provided by the invention is simple in operation method, the prepared mica powder granules have high purity, and the production cost is low, therefore the process is suitable for popularization and use.

Description

technical field [0001] The invention relates to the technical field of mica powder, in particular to a mica powder dry powder granulation process. Background technique [0002] Mica powder is a non-metallic mineral containing various components, mainly SiO 2 , the content is generally around 49%, Al 2 o 3 The content is about 30%. Mica powder has good elasticity and toughness. Insulation, high temperature resistance, acid and alkali resistance, corrosion resistance, strong adhesion and other characteristics, it is an excellent additive. It is widely used in electrical appliances, welding electrodes, rubber, plastics, papermaking, paints, coatings, pigments, ceramics, cosmetics, new building materials and other industries, and has a wide range of uses. Most of the mica powder is in the form of powder. During use, the mica powder is easy to fly and will cause dust pollution to the air. [0003] Therefore, we propose a mica powder dry powder granulation process to solve t...
