Vertical mill can help pyrophyllite powder making

20/10/2023

Pyrophyllite is a clay mineral with low hardness. It has the characteristics of high temperature resistance, chemical corrosion resistance, poor electrical 

conductivity and plasticity. It is widely used in ceramics, refractory materials, glass fiber and other industries. Pyrophyllite powder is hydrated aluminum

silicate fine powder, which is also widely used in emerging industries such as high-end equipment manufacturing, new energy, and biotechnology.

When pyrophyllite is used in fields such as fiberglass and refractory materials, it needs to be ground to a certain fineness before it can be used. 

At present, the vertical mill has become the mainstream equipment to promote the large-scale production of pyrophyllite. As an expert in powder 

equipment manufacturing, Liming Heavy Industry's LM series vertical mills have strong adaptability to pyrophyllite. The equipment is efficient and 

energy-saving, and the finished products are of high quality. Enterprises have reported very good results from the use of the equipment.

Technical advantages and features:

1. Integrated design, one machine for multiple purposes

It integrates crushing, drying, grinding, grading and conveying, with a compact layout; it can be used for grinding a variety of materials, reducing 

investment costs.

2. High grinding efficiency and good discharge quality

It has high classification accuracy and high grinding efficiency; the finished product has uniform particle size distribution, good quality, good fluidity

 and high activity.

3. Easy maintenance and high degree of automation

The PLC fully automatic control system can realize remote control, reduce labor, improve work efficiency and reduce maintenance costs.

4. High yield, wear resistance, energy saving and environmental protection

The wear-resistant surfacing roller sleeve is used, which has low wear and high single-machine production capacity; the whole machine system

 has small vibration and low equipment failure rate. The entire system is sealed and operates under full negative pressure, with no dust spillage.

Vertical grinding pyrophyllite process flow:

1. Crushing: Large pieces of pyrophyllite are transported to the raw material warehouse by special vehicles, and then the materials are sent to the 

jaw crusher by a forklift for crushing until they are smaller than the maximum feed size of the grinding mill.

2. Grinding: The crushed pyrophyllite small pieces are sent to the storage hopper through the elevator, and then sent to the grinding chamber of 

the mill uniformly and quantitatively through the feeder for grinding.

3. Classification: The ground materials are classified by the classification system. Qualified products are screened by the screening system and then 

enter the pulse collector through the pipeline. Unqualified products fall back into the grinding chamber to continue grinding.

4. Collection: Powder that meets the fineness enters the dust collector with the air flow through the pipe for separation and collection. The collected 

finished powder is sent to the finished product silo by the conveyor through the discharge port, and then unified using a powder loading tanker or 

automatic baling machine. Package.

With more than 30 years of production experience, Liming Heavy Industry continues to provide customers with a variety of series of grinding mills, builds professional 

and high-quality grinding production lines for customers with high-quality products and high-quality services, helps customers create huge value, and

wins a large number of customers. favor.

In the next step, Liming Heavy Industry will continue to improve its grinding equipment technology, provide higher-quality grinding equipment for pyrophyllite 

grinding enterprises, help the development of the pyrophyllite grinding industry, meet the needs of industrial scale, refinement, and intensive 

grinding, and provide a good foundation for the pyrophyllite industry. Provide guarantee for green transformation and development!
