Kaolin is a non-metallic mineral with kaolin minerals as the main part. Its ground form, kaolin powder, is widely used, ensuring a constant demand. What are the special characteristics, applications, and grinding processes of kaolin?
Hard Quality
– Hardness: 3-4（Mohs）
– Plasticity: after crushing
– Color: Dark gray, brown (high-quality impurities)
Light Quality
– Hardness: Soft
– Plasticity: Strong
– Sand Content: Less than 50%
Sandy Quality
– Hardness: Soft
– Plasticity: Moderate
– Sand Content: Greater than or equal to 50%
Key ingredient for various types of ceramics
Enhances aesthetics and durability of ceramic products
Used as filler and coating
Improves paper smoothness, brightness, and quality
Reduces production costs
Serves as a filler and reinforcing agent
Strengthens rubber products
Increases wear resistance and product lifespan
High whiteness, fine particle size, and good suspension properties
Used in enamel coatings for aesthetic and durable surfaces
Used in the production of refractory materials
Maintains stability at high temperatures
Production of polyaluminum and water treatment
Manufacture of chemical agents like alum and aluminum chloride
All applications of kaolin must be processed into a fine powder before it can be added to other materials to achieve full fusion.
Crushing
The kaolinite is sent to the jaw crusher and broken to a fineness that can enter the mill (15mm-30mm).
Grinding
The small pieces of broken kaolin are sent to the storage hopper by the elevator, and then evenly and quantitatively fed into the mill by the feeder for grinding.
Classification
The ground material is graded by the classifier, and the unqualified part is returned to the host machine for re-grinding.
Collection
The powder that meets the fineness is collected by the air flow through the pipe into the powder collection system, and the finished powder is sent to the finished product warehouse.
