Embodiment Construction

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.

[0024] refer to figure 1 , a preparation method of phlogopite powder, comprising the following steps:

[0025] S1: material selection, manually screen the phlogopite ore, and wash and dry the screened phlogopite ore;

[0026] S2: wet flaking, the selected high-quality phlogopite ore raw materials are wet flaked, washed, removed, soaked, and rolled to form a flaky primary material A;

[0027] S3: Grinding, drying and dehydrating the flake raw material A at low temperature, rolling it with a wheel mill, and then grinding it with a grinder to produce phlogopite particles B;

[0028] S4: Washing and screening, put the phlogopite particles B into the separation sieve, a...

Abstract

The invention discloses a preparation method of phlogopite powder. The preparation method comprises the following steps of selecting materials; artificially screening phlogopite ore; performing flushing and drying treatment on the screened phlogopite ores; peeling the sheets by a wet process; using wet sheet peeling on the picked high-quality phlogopite ore raw materials; performing water washing,impurity removal, soaking and milling to prepare flaky primary materials A; performing grinding; performing low-temperature drying dewatering on the flaky primary materials; performing milling by using a wheel milling machine; next, performing grinding by a grinding machine; preparing phlogopite particles B; performing water washing screening; feeding the phlogopite particles B into a separationsieve; injecting a proper amount of pure water; removing floating impurities. The impurities with small density can be conveniently removed; acid soluble impurities such as calcium carbonate can be removed; the impurities of the phlogopite powder can be favorably improved; the product quality is improved; the recovery is convenient; the yield is improved; the production cost is reduced; the filtering efficiency is improved; the work efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of phlogopite powder, in particular to a preparation method of phlogopite powder. Background technique [0002] Phlogopite is one of the muscovite minerals. It is a monoclinic layered silicate mineral. It is an aluminum silicate containing iron, magnesium and potassium. If the iron in the phlogopite is not too much , it can be used as an electrical insulating material, and it is widely used in chemical industries such as building materials industry, fire protection industry, fire extinguishing agent, welding rod, plastics, electrical insulation, paper making, asphalt paper, rubber, and pearlescent pigments. Pure natural green phlogopite powder can be used directly in pressed powder, BB cream, loose powder, liquid foundation, mask, etc. without adding any pigment, and has received high praise from the industry. The purity of the phlogopite powder produced by the existing production process is not high, the r...
