HGMring roller mill is distinct in its structure. The core grinding area consists of a circular assembly of 18 to 44 grinding rollers, typically arranged in 3-4 layers.

These rolls grind materials against a central ring, a setup that enables consistent, efficient grinding.

This configuration not only provides stability during operation but also optimizes the grinding process, allowing for a high-quality powder output.

HGM ring roller mill excels at producing fine and ultrafine powders, with particle sizes ranging from 150 mesh to 3,000 mesh (where a higher mesh count indicates finer powder).

Tips: 150 mesh equates to particles roughly 100 microns in size, while 3,000 mesh results in particles as small as a few microns.

Specifically, HGM ring roller mill can produce powders with a particle size distribution in which D97 (97% of particles) measures less than 5 microns. Additionally, as much as 60% of particles can reach sizes as fine as 2 microns, which is ideal for specialized applications requiring ultrafine consistency.

Another important capability of HGM ring roller mill is its high production output. Certain models can process up to 30tons of material per hour, making it an excellent choice for industries with high-volume needs.

This combination of fine grinding capacity and robust throughput positions the ring roller mill as one of the most versatile and widely-used options in the powder processing industry.

Applications of the Ring Roller Mill

One of the primary uses of the ring roller mill is in processing non-metallic minerals, especially those with a Mohs hardness rating of 7 or below. This includes materials such as:

Bentonite

  • Calcium Carbonate (CaCO₃): Widely used in industries like construction, paper, and plastics. Heavy calcium carbonate, a finely ground form of calcium carbonate, is particularly well-suited to the ring roller mill due to its relatively low hardness.
  • Limestone (CaCO₃): Similar to calcium carbonate, limestone is used in cement, paint, and agriculture. The ring roller mill enables fine and consistent grinding, making limestone a key application.
  • Dolomite (CaMg(CO₃)₂): Often used in ceramics and glass manufacturing. Its balanced chemical composition and moderate hardness make it a good candidate for processing in ring roller mills.
  • Calcite (CaCO₃): This mineral is prized for its whiteness and is commonly used in paints, coatings, and plastics.
  • Barite (BaSO₄): Known for its high density, barite is often used in drilling fluids for oil and gas, as well as in paints and coatings.
  • Bentonite: This clay mineral is used as a binder, thickener, and absorbent. The ring roller mill can achieve the fine particle sizes needed for bentonite’s role in construction and environmental applications.
  • Carbon Black: Used in inks, paints, and tires, carbon black benefits from the ring roller mill’s ability to produce ultrafine particles.

In particular, the mill is renowned for its efficiency in grinding groundcalcium carbonate, a critical material for industries requiring high-purity and fine-powder calcium carbonate for various end products. With its high capacity and fine-tuning abilities, the ring roller mill meets the diverse needs of these industries and provides a dependable solution for consistent powder production.

Advantages of the Ring Roller Mill

The ring roller mill offers several advantages that contribute to its popularity in the fine and ultrafine powder industry:
