Kaolin is widely used in ceramics, paper, plastics, and coatings. Building an efficient processing plant requires careful planning, from raw material handling to final product packaging.

1. Know the Material

Kaolin typically has 10–15% moisture and a Mohs hardness of 1–2. Processing targets fineness between 325–2500 mesh, depending on application. Brightness, particle size, and impurities determine downstream value.

2. Core Processing Steps

Crushing: Jaw crusher reduce raw ore to <50 mm.

Grinding: Raymond or vertical roller mill achieve fine powders.

Classification: Air classifiers ensure uniform particle size.

Additional steps may include magnetic separation for iron removal and calcination for brightness improvement.

3. Equipment Selection

Key factors include desired output (1–100 t/h), energy efficiency (vertical mill cut power use by up to 50%), automation level (PLC systems for easy control), and dust collection (bag filters for clean operations).

4. Layout & Design

Efficient workflow reduces handling costs. Plants should be designed with logical material flow, proper space for maintenance, integrated dust suppression, and room for future expansion.

5. Operating Best Practices

Regular maintenance, quality monitoring, and staff training are essential. Energy audits and process optimization further improve efficiency.
