Kaolin milling line for Indonesia fine powder

Introduction to Kaolin Processing in Indonesia

Indonesia is one of the world’s largest producers of high-quality kaolin, a naturally occurring clay mineral widely used in papermaking, ceramics, paints, rubber, plastics, and cosmetics. The demand for ultra-fine kaolin powder with particle sizes below 10 microns (1250 mesh) has been growing rapidly, especially in the export-oriented Indonesian mining and processing industry. To achieve consistent fineness, high purity, and energy-efficient production, a well-designed kaolin milling line is essential. Shanghai Zenith Machinery Co., Ltd., as a leading Chinese manufacturer of ore grinding equipment, offers comprehensive solutions for Indonesia’s fine powder producers, combining advanced technology with robust after-sales support.

Key Considerations for a Kaolin Milling Line

A typical kaolin milling line consists of crushing, grinding, classifying, and packaging stages. Since raw kaolin often contains moisture and impurities, pre-drying and beneficiation may be required. For fine powder production (325 mesh to 2500 mesh), the choice of grinding mill is critical. Factors such as feed size, desired fineness, capacity, and energy consumption directly affect the project’s profitability. In Indonesia, where power supply can be unstable, selecting mills with high reliability and low operating costs is paramount.

Recommended Grinding Mills for Indonesian Kaolin

Based on years of field experience and technical innovation, Shanghai Zenith recommends two core grinding mills for Indonesia’s fine kaolin powder lines: the LUM Ultrafine Vertical Mill and the MTW Trapezium Grinding Mill.

1. LUM Ultrafine Vertical Mill – For Ultra-Fine Powder (5-30 μm)

The LUM series integrates grinding, drying, classifying, and conveying in one compact unit. Its unique roller-and-table design, combined with a high-efficiency classifier, can produce powder with a D97 of 5-30 microns (approximately 500-2500 mesh). This makes it ideal for high-value kaolin applications such as paper coating and high-gloss paints. The mill is equipped with an intelligent control system that automatically adjusts parameters, reducing operator intervention. Key parameters include main motor power from 220 kW to 400 kW, capacity ranging from 1.6 to 15 t/h, and low noise operation. For Indonesian clients seeking to maximize profit from high-grade kaolin, the LUM1525 or LUM1632 is an excellent choice.

2. MTW Trapezium Grinding Mill – For Medium to Fine Powder (0.045-1.6 mm)

When the target fineness is between 0.045 mm (325 mesh) and 1.6 mm (10 mesh), the MTW Trapezium Grinding Mill offers outstanding efficiency and durability. Its patented multi-stage sealing design prevents dust leakage, which is particularly important in tropical humid climates. The MTW175G model, for example, can process up to 25 t/h of kaolin with a feed size of up to 40 mm, requiring only a main motor of 160 kW. This mill is also suitable for drying kaolin with a certain moisture content as the hot air can be introduced into the grinding chamber. Many Indonesian kaolin producers have adopted the MTW138Z for its balance of capacity and precision.

Complete Milling Line Configuration

For a typical Indonesia fine powder plant targeting 600 mesh (D97 = 20 μm), a recommended configuration includes a jaw crusher (primary crushing), a bucket elevator, a vibrating feeder, the LUM1632 Ultrafine Vertical Mill, a pulse dust collector, a screw conveyor, and a product silo. The entire system is controlled by a PLC panel, ensuring smooth automatic operation. Below is a simplified flow diagram:
