Pyrophyllite Industrial Powder Grinding Mill

19/10/2021 admin

The pyrophyllite industrial powder grinding mill can grind pyrophyllite into coarse powder or fine powder as required. Pyrophyllite mills include ultrafine grinding mills, vertical grinding mills, high-pressure grinding mills, coarse grinding mills, etc., which are used in production lines with different grinding requirements.

Ordinary pyrophyllite powder (80-325mesh) is usually ground by a high-pressure mill or Raymond mill; medium and high-end pyrophyllite powder (150-3000mesh) is usually ground by a superfine powder mill or vertical roller mill, and pyrophyllite coarse powder (less than 8mm) is usually ground by a coarse grinding machine.

About pyrophyllite:

Pyrophyllite is an aluminosilicate mineral. The color is generally white, slightly yellowish or greenish, with white streaks. Glass luster, with a pearl-like halo. The hardness is small (1~1.5 or 1~2), with a smooth feeling. It has stable chemical properties, good heat resistance, and insulation, and is a dielectric material for sealing and transmitting pressure.

Used as: It is widely used in ceramics, metallurgy, building materials, chemical industry, light industry, and other industrial sectors.

Adding pyrophyllite to the ceramic blank can reduce the firing temperature, shorten the drying time, increase the firing strength, reduce glaze defects, and make the ceramic perfect.
Production fineness: about 200 mesh

Pyrophyllite contains silicon dioxide and aluminum oxide, does not melt when heated, and is a raw material for the manufacture of aluminum silicate refractory materials.
Production fineness: 3mm
Refractory materials, refractory bricks

Pyrophyllite processing technology:

The crushing and grinding of pyrophyllite have two purposes: one is to prepare for the beneficiation and purification operation, to prepare the pyrophyllite powder raw material that dissociates from the impurity mineral monomer. The second is to directly process pyrophyllite powder products for pyrophyllite whose purity can meet the requirements of the application field.

Pyrophyllite processing process:

1. Crushing stage: Large pieces of material are crushed by the crusher to the fineness (15mm-50mm) that can enter the mill.

2. Grinding stage: Small pieces of material that meet the conditions for entering the mill are uniformly and quantitatively fed into the grinding chamber of the mill through the conveying and feeding system, and pulverized in the grinding cavity.

Main production equipment for ultra-fine pyrophyllite (dry production)
HGM ultrafine grinding mill can produce medium and high-end pyrophyllite powder of 150-3000 mesh, simple operation, convenient maintenance, and fineness can be adjusted freely.

CLUM ultra-fine vertical roller mill can produce high-end pyrophyllite powder of 150-3000 mesh, with high fine powder content, good powder shape, high whiteness, and fineness that can be adjusted freely.

The high-pressure suspension roller mill can produce ordinary pyrophyllite powder of 80-325 mesh, with stable operation and low investment.

Pyrophyllite wet purification (wet production)
After flotation or wet magnetic separation, the ultra-fine crushing process can be carried out, and the wet process can be used. After the wet crushing reaches the required fineness, it is dehydrated (filtered and dried).

3. Classification stage: the ground material will be classified by the classifier along with the airflow of the system, and the unqualified powder will be classified by the classifier and returned to the main machine grinding cavity for re-grinding.

4. Powder collection stage: The powder that meets the fineness enters the powder collection system with the airflow through the pipeline, and the gas and powder are separated. The finished powder is sent to the finished product silo by the conveying device and then is packaged by a powder tanker or an automatic baler.

Coarse flour process:

Crushing stage: Large pieces of material are crushed by the crusher to the fineness (15mm-50mm) that can enter the mill.

Pulverizing stage: the small pieces of material that meet the conditions of entering the mill are uniformly and quantitatively fed into the mill by the conveying and feeding system and can be formed at one time.

Intro of pyrophyllite industrial powder grinding mill:

Pyrophyllite powder is a product of pyrophyllite that is collected, selected, analyzed, ground, and mixed evenly according to the needs of the application. The powder has a creamy feel and is used as an additive to mix with other pigments or to adjust pigments.

Commonly used crushers for pyrophyllite include jaw crushers, cone crushers, and impact crushers. Commonly used mill equipment mainly includes a high-pressure grinding mill, super fine powder mill, vertical roller mill, wet mill, and so on.

When pyrophyllite is used in papermaking, plastics, rubber, high-performance refractory materials, and other fields, it must be super finely crushed. At present, there are two processes for ultrafine pulverization of pyrophyllite: dry method and wet method. The dry process mainly uses high-pressure mills, ultra-fine grinding, etc.; the wet process mainly uses grinding and stripping machines and stirring mills.

The following introduces the equipment required for the more important milling link in the dry production line:
