4R3216 Raymond Mill for Ultra Fine Powder Grinding

Unlocking Precision in Ultra Fine Powder Production with 4R3216 Raymond Mill

In the demanding world of industrial powder processing, achieving consistent ultra-fine results requires robust and sophisticated equipment. The 4R3216 Raymond Mill stands as a proven workhorse in this sector, engineered to deliver reliable performance for a wide spectrum of materials. Its design philosophy centers on creating a perfect balance between grinding efficiency, operational stability, and final product quality.

The core of the 4R3216’s effectiveness lies in its grinding assembly. The “4R” denotes four grinding rollers, which work in conjunction with a grinding ring to pulverize material through a combination of crushing and grinding actions. The 3216 specification refers to the diameter and height of the grinding ring, providing a substantial grinding surface area. This configuration ensures that materials are ground uniformly, resulting in a narrow particle size distribution that is critical for high-value applications.

Key Applications and Material Versatility

The versatility of the 4R3216 Raymond Mill is one of its most significant advantages. It is adept at processing non-flammable and non-explosive materials with a Mohs hardness of less than 9.3 and humidity below 6%. Common applications include:

  • Minerals: Efficiently grinding limestone, calcite, dolomite, barite, talc, and gypsum.
  • Industrial Materials: Processing activated clay, activated carbon, and bentonite.
  • Chemical Industry: Producing fine powders for paints, coatings, and various chemical compounds.

The final product fineness can be adjusted within a range of 80 to 425 mesh (approximately 180 to 40 microns), making it suitable for many industrial standards where a fine, consistent powder is required.

When to Consider an Advanced Alternative

While the 4R3216 Raymond Mill is an excellent solution for many fine powder applications, production demands are constantly evolving towards even finer specifications and higher efficiency. For operations requiring powder fineness between 325 and 2500 meshes, a specialized ultra-fine grinding mill becomes necessary.

For these advanced needs, we highly recommend our MW Ultrafine Grinding Mill. This machine is specifically engineered for customers who need to make ultra-fine powder with superior efficiency. It is equipped with an efficient pulse dust collector and muffler, ensuring that the entire production process has minimal impact on the environment. With an input size of 0-20 mm and a capacity ranging from 0.5 to 25 tph, the MW Series represents the next step in grinding technology.

The MW Ultrafine Grinding Mill boasts several groundbreaking features. Its newly designed grinding curves for the roller and ring enhance grinding efficiency significantly. With the same fineness and power, its production capacity is 40% higher than that of jet mills or stirred grinding mills. Furthermore, its innovative design includes no rolling bearings or screws in the grinding chamber, eliminating common failure points and allowing for external lubrication without shutdown, enabling continuous 24/7 production.

Frequently Asked Questions (FAQ)

What is the main difference between the 4R3216 Raymond Mill and the MW Ultrafine Grinding Mill?

The primary difference lies in the fineness range and technological approach. The 4R3216 is ideal for fineness up to 425 mesh, while the MW Ultrafine Grinding Mill can produce powders between 325 and 2500 meshes, utilizing more advanced powder selection and grinding curve technology for higher efficiency in the ultra-fine spectrum.

Can these mills handle high-moisture materials?

The standard 4R3216 and MW mills are designed for materials with humidity below 6%. For materials with higher moisture content, integrated drying systems can be considered as part of a custom solution. Our LUM Ultrafine Vertical Grinding Mill, for instance, integrates drying and grinding effectively.

How is the final product fineness controlled?

Fineness is primarily controlled by the built-in powder separator. In the MW Ultrafine Mill, a multi-head cage-type powder selector allows for precise adjustment of the product fineness. The speed of the classifier rotor can be adjusted to control the cut-point, allowing only particles of the desired size to leave the grinding chamber as product.

What kind of after-sales support do you offer?

We offer comprehensive after-sales support, including installation guidance, operational training, technical consulting, and a reliable supply of genuine spare parts. Our global service network ensures that professional assistance is available whenever needed.
