Vertical Mill and Talc

Talc, a common silicate mineral with magnesium silicate as its main component, has diverse appearances and crystal forms, endowing it with properties such as lubricity, heat resistance, and chemical stability. It is widely used in industrial fields such as papermaking, plastics, coatings, cosmetics, medicine, ceramics, and rubber. Traditional talc grinding relies on equipment like ball mills, which have drawbacks including high energy consumption, low output, limited fineness adjustment, weak drying capacity, and significant noise and dust pollution. However, vertical mills effectively address these shortcomings.

Advantages of Vertical Mills in Grinding Talc

High Grinding Efficiency

Based on the material bed grinding principle, it has high energy utilization efficiency, saving 30%-50% more energy than ball mills and reducing costs for enterprises.

Flexible Particle Size Adjustment

The dynamic classifier can precisely adjust the fineness of talc powder within the range of 80-600 mesh by adjusting the rotation speed, meeting the needs of multiple industries.

Integrated Drying and Grinding

Equipped with a hot air system, it realizes simultaneous grinding and drying, simplifying the process and improving efficiency.

Compact Structure and Small Footprint

Integrating functions such as crushing and grinding, it covers an area of approximately 50% of that of a ball mill, saving costs and time.

Environmentally Friendly and Low Noise

Operated under negative pressure and equipped with a pulse bag filter, it ensures that dust emissions meet standards. It runs stably, with noise 20-30 decibels lower than that of ball mills.

Low Metal Loss

The grinding rollers and grinding disc do not directly contact, resulting in little wear and low metal loss. This improves the whiteness of the product, enhances competitiveness, and reduces operating costs.

Process of Grinding Talc with Vertical Mill

Crushing

Jaw crushers are used for coarse crushing, and hammer crushers for medium and fine crushing, reducing talc to below 30mm to meet subsequent processing requirements, improve grinding efficiency, and ensure product quality.

Feeding

Bucket elevators vertically lift the talc, and quantitative feeders uniformly and continuously feed it into the vertical mill to ensure the continuity and stability of production.

Grinding and Drying

The grinding disc rotates, and the grinding rollers crush the talc, while hot air dries it simultaneously, realizing the transformation from raw materials to dry talc powder, improving efficiency, and simplifying the process.

Classification

The dynamic classifier accurately screens the talc powder, controlling the product fineness by adjusting the rotation speed to ensure product quality and particle size uniformity.

Collection and Finished Products

The pulse bag filter collects the talc powder, which is then transported to the finished product warehouse by conveying equipment and packaged according to market demand for convenient transportation and sales.
