Bauxite Ore Milling Equipment

-- Steady & Reliable Manufacturer --

Introduction

Bauxite milling is the first step in the Bayer process for alumina production. The goal is to create a fine, consistent slurry that allows for efficient, low-temperature digestion. Our bauxite milling equipment is designed to reliably grind this often sticky and variable ore to the required fineness. We focus on delivering a system that offers high availability, low maintenance, and a consistent particle size distribution, which are critical factors for optimizing the efficiency and cost-effectiveness of your entire alumina refining operation.

Applications

  • Alumina Production: Grinding bauxite ore as a precursor to the Bayer process for producing alumina (Al₂O₃).
  • Cement Manufacturing: Used as a source of alumina in the production of special cements.
  • Refractory Materials: Processing of calcined bauxite for the manufacturing of high-alumina refractories.
  • Abrasives: Grinding calcined bauxite to produce abrasives.

Advantages

  • Handles Moisture: Our vertical mills can effectively grind and dry bauxite with high moisture content in a single pass, simplifying the process flow sheet.
  • Consistent Product Fineness: The high-efficiency classifier ensures a stable particle size distribution, which is crucial for predictable and efficient downstream digestion.
  • Robust and Reliable: Designed for the challenging conditions of a refinery, with heavy-duty construction and highly wear-resistant grinding elements.
  • Lower Specific Energy: Our grinding technology provides a lower kWh per ton of bauxite processed compared to older technologies, reducing your operational expenditure.

Payment & Shipping

We accept standard international payment methods, including T/T (30% deposit, 70% before shipment) and confirmed L/C. We partner with leading global freight forwarders to offer reliable and cost-effective shipping options (CIF, FOB, EXW) to all major seaports. All machines are securely packed in export-standard containers for maximum protection.

Frequently Asked Questions

  • Q: Bauxite can be very sticky. How does your equipment prevent blockages?
  • A: Our vertical mills have an optimized internal design with a more vertical material flow path, which inherently reduces the chances of material build-up. Additionally, the integration of hot gas for drying helps to reduce stickiness before grinding, ensuring smooth operation.
  • Q: Is dry grinding or wet grinding better for bauxite?
  • A: Dry grinding, especially with our vertical mills, is increasingly preferred. It is more energy-efficient as it eliminates the need to add water and then evaporate it later. It simplifies the circuit and gives precise control over the particle size before it enters the digestion tanks.
