Pyrophyllite and Wollastonite Milling

-- Steady & Reliable Manufacturer --

Introduction

Pyrophyllite and wollastonite are high-value industrial minerals used as functional fillers in plastics, ceramics, and paints. Their value comes from their unique particle shapes—pyrophyllite is platy, and wollastonite is acicular (needle-like). The challenge in milling is to reduce the particle size while preserving these unique shapes. Our specialized milling systems are designed for this purpose, using controlled grinding and classification to produce powders that provide maximum reinforcement, dimensional stability, and other benefits in your final product.

Applications

  • Plastics & Polymers: Used as reinforcing fillers in polypropylene and nylon to improve stiffness, HDT, and scratch resistance.
  • Ceramics: Pyrophyllite reduces thermal expansion and firing shrinkage. Wollastonite improves strength and reduces crazing in glazes.
  • Paints & Coatings: Improves mechanical strength, crack resistance, and scrub resistance.
  • Refractories: Pyrophyllite is used in refractory compositions due to its low thermal expansion.

Advantages

  • Particle Shape Preservation: Our mills are configured to favor delamination and breakage along natural cleavage planes, which helps to maintain the high aspect ratio (length-to-width) of the particles.
  • High Fineness & Purity: Capable of producing ultrafine powders while offering options for ceramic lining to ensure high brightness and purity for demanding applications.
  • Precise Top-Size Control: The integrated classifier is crucial for removing any oversized particles that could act as defects or stress points in a polymer or ceramic matrix.
  • Cost-Effective Production: An energy-efficient dry grinding process that provides a high-value functional filler at a competitive production cost.

Payment & Shipping

We offer secure payment terms via T/T and L/C. The machinery is carefully disassembled, protected, and professionally loaded. We provide a detailed packing list that corresponds with our assembly manual, making re-installation at your site clear and efficient.

Frequently Asked Questions

  • Q: Why is preserving the needle-like shape of wollastonite so important?
  • A: The long, interlocking needles of wollastonite act like microscopic reinforcing bars (rebar) inside a plastic or ceramic matrix. This is what provides the significant increase in stiffness, impact strength, and dimensional stability. If the needles are broken into small, blocky particles, this reinforcing effect is lost.
  • Q: What is "aspect ratio" and how does your mill control it?
  • A: Aspect ratio is the ratio of a particle's length to its width. For these minerals, a high aspect ratio is desirable. While no mill can perfectly preserve it, our system's combination of gentle grinding force and rapid removal of fine particles by the classifier helps to minimize breakage across the short axis of the particles, thus maintaining the highest possible average aspect ratio in the final product.
