Kaolin Raymond Mill from Liming Heavy Industry – Trusted Technology for Mineral Processing

Kaolin, also known as china clay, is a versatile industrial mineral widely used in ceramics, paper coating, rubber, plastics, paint, and refractories. The value of kaolin increases significantly after fine grinding. Choosing the right grinding mill directly affects product quality, production cost, and profitability. Liming Heavy Industry offers a proven solution: the Kaolin Raymond Mill, specifically designed for processing kaolin with moderate hardness and moisture content.

The Raymond mill, also called a Raymond roller mill, has been a standard technology in the mineral grinding industry for decades. Liming Heavy Industry has modernized this classic design with improved grinding rollers, a more efficient classifier, and a sealed negative-pressure system. The result is a kaolin grinding mill that delivers consistent fineness, low energy consumption, and clean operation.

For kaolin with a feed size up to 30 mm and moisture below 6%, the Liming Raymond mill can produce powder ranging from 80 mesh to 600 mesh (0.18 mm to 0.023 mm). The built-in whizzer classifier adjusts the fineness without stopping the machine. This flexibility allows operators to switch between different product specifications quickly.

One of the key advantages of the Liming Kaolin Raymond Mill is its compact footprint. Unlike ball mills that require separate classifiers and elevators, the Raymond mill integrates grinding, classifying, and conveying into one unit. This reduces civil construction costs and simplifies maintenance.

Liming Heavy Industry has supplied hundreds of Raymond mills to kaolin processing plants worldwide, including in Southeast Asia, South America, Africa, and the Middle East. With a strong service network and readily available spare parts, the Kaolin Raymond mill remains a first-choice equipment for small to medium capacity kaolin grinding lines (1–20 tons per hour).

 FAQs :

1. Q: What is the maximum feed size for kaolin into the Raymond mill?
   A: The recommended maximum feed size is 30 mm. Larger feed sizes may damage the grinding rollers or reduce throughput.

2. Q: What final fineness can the kaolin Raymond mill achieve?
   A: It can produce powder from 80 mesh to 600 mesh (approximately 180 to 23 microns). For finer requirements (e.g., 1250 mesh), Liming recommends the ultra-fine LUM vertical mill.

3. Q: Can the Raymond mill handle wet kaolin?
   A: No. Feed moisture should be below 6%. Wet kaolin will stick to the grinding ring and classifier, causing blockages. Pre-drying is required.

4. Q: What is the typical capacity for kaolin grinding?
   A: Depending on model and fineness, capacity ranges from 1 to 20 tons per hour. Liming offers models from 3R to 6R to match different output requirements.

5. Q: Does Liming provide EPC service for kaolin grinding lines?
   A: Yes. Liming offers complete EPC solutions including mill, fan, cyclone, bag filter, control panel, and installation guidance.
