Final Products and Application Fields:
The powder processed by the calcite vertical mill is called ground calcium carbonate (GCC), an indispensable filler and raw material in many industrial fields:
Plastics Industry: Used to improve the strength, rigidity and surface gloss of plastic products.
Paints and Coatings Industry: As an extender pigment, it enhances the hiding power, durability and fluidity of coatings.
Paper Industry: As a filler and coating, it improves the whiteness, smoothness and printability of paper.
Artificial Stone Industry: Serves as the main base material for producing artificial quartz stone and artificial marble.
Adhesives and Sealants Industry: As a functional filler, it regulates the physical properties of products.
The calcite vertical mill is a large-scale industrial grinding equipment specially designed for processing calcite, a natural calcium carbonate mineral. Its core features lie in its vertical structure and efficient material bed grinding principle, enabling it to grind massive or granular calcite into powders of various fineness to meet the needs of different industrial fields.
Outstanding Technical Advantages
Compared with traditional equipment, the calcite vertical mill has obvious advantages:
High Efficiency and Energy Saving: Its energy consumption is usually 30%-40% lower than that of traditional ball mills, as it crushes materials directly with high energy utilization rate.
Adjustable Product Fineness: By conveniently adjusting the rotation speed of the classifier, it can easily produce different products ranging from coarse powder (e.g., 100 mesh) to ultra-fine powder (e.g., 2500 mesh).
Small Floor Space: The vertical structure is compact, occupying much less floor space than ball mill systems with the same output.
Low Noise and Environmental Friendliness: The entire system operates in a closed manner, generating less dust and lower operating noise.
Low Comprehensive Cost: Although the initial investment may be higher, its low power consumption, low wear and tear, and low maintenance costs result in more advantageous long-term operating costs.
Core Working Principle: Material Bed Grinding
Different from traditional ball mills (which crush materials by steel ball impact), the working method of the vertical mill is as follows:
Crushing: Materials enter from the top and fall onto the rotating grinding disc. Grinding rollers controlled by a hydraulic system press the material layer (material bed) on the disc to crush it.
Drying: While grinding, hot air introduced from the bottom can dry moisture-containing materials, achieving two goals at once.
Classification: The crushed fine powder is carried by the air flow to the classifier at the top. Qualified fine powder is selected and collected, while unqualified coarse powder is thrown back to the grinding disc for re-grinding.
This process integrates grinding, drying and classification, featuring extremely high efficiency.
