Ceramic ball mill is a kind of grinding equipment commonly used in industrial production, and is widely used in ceramics, chemicals, mining, electronics, coatings, medicine and other fields.It is one of the types of ball mills. Ceramic ball mill has become one of the indispensable dressing equipment in many industries with its high efficiency, energy saving and environmental protection.

How to define ceramic ball mill?

Ceramic ball mill is a high-efficiency equipment used for grinding, mixing or dispersing solid materials, mainly used in ceramics, metallurgy, chemical industry, pharmaceutical and other industries. The core feature of ceramic ball mill is that it uses grinding media made of ceramic materials (such as alumina, zirconium silicate, etc.), and crushes and refines the materials through rotation in the horizontal cylinder, which can process the raw materials to micron or even nanometer particles.

Ceramic ball mill is particularly suitable for processing high-purity, high-hardness or metal-sensitive materials due to its corrosion resistance, environmental protection and high efficiency.

Structural composition of ceramic ball mill

4 parts of ceramic grinding ball mill consists

Cylinder: horizontal cylindrical structure, the inner wall is usually lined with wear-resistant rubber or ceramic layer to prevent cylinder wear.

Grinding media: Ceramic balls (such as alumina balls, zirconium silicate balls), with diameters ranging from a few millimeters to tens of millimeters, are mixed and loaded in proportion.

Drive device: A combination of a motor and a reducer drives the cylinder to rotate at a specific speed.

Feed and discharge device: Supports dry or wet operation, equipped with a sealed feed port and discharge valve.

How does a ceramic ball mill work?

The ceramic ball mill is mainly composed of a horizontally rotating cylinder, in which a large number of ceramic balls are installed as grinding media. When the cylinder rotates, the material is lifted to a certain height together with the ceramic balls, and then falls or rolls down along a parabola due to gravity, producing a strong impact and grinding effect, thereby crushing and grinding the material.

4 processes to understand the working principle of ceramic ball mill

1. Material and medium loading:

The material enters the cylinder through the feed port and is filled with ceramic medium at the same time (the filling rate is usually 30%~50% of the cylinder volume). Dry operation directly adds powdered materials; wet operation requires the addition of liquid (such as water or solvent) to form a slurry.

2. Cylinder rotation and medium movement:

The cylinder rotates at 60%~80% of the critical speed (to prevent the medium from sticking to the wall). The medium is brought to the top of the cylinder under the action of centrifugal force and friction, and then falls freely due to gravity, exerting impact force on the material.

The rolling and sliding between the media and the media and the cylinder generate rolling and shearing forces to achieve material refinement.

3. Layered grinding mechanism:

The large diameter medium (such as 10~50 mm) is located at the bottom of the cylinder, responsible for the initial crushing of large particles; the small diameter medium (such as 5~10 mm) is in the upper layer, further refining the particles to micron level.

The material circulates between the media, undergoing a step-by-step grinding process of “crushing → refinement → re-crushing”.

4. Energy transfer

Energy is mainly transferred through collision and friction between the media. The high hardness and wear resistance of the ceramic media reduce its own loss. The ceramic powder produced by wear can be separated by a grading device to avoid contamination of the final product.

What are the characteristics of ceramic ball mill?

Good wear resistance: Since the grinding media and some vulnerable parts of the ceramic ball mill are made of ceramic materials, it has better wear resistance and is suitable for materials with higher hardness.

High product purity: Ceramic materials have good chemical stability and will not pollute the materials, ensuring the purity of the product.

Significant energy-saving effect: The ceramic ball mill adopts advanced design concepts, optimizes the mill structure, and reduces energy consumption.

Easy operation: High degree of automation, easy operation, and easy to monitor and control the production process.

Low noise: Due to the special design and materials, the ceramic ball mill has low noise during operation.

Where is ceramic ball mill used?

Ceramic industry: used for mixing and grinding ceramic raw materials to improve the uniformity and plasticity of raw materials.

Chemical industry: used for crushing and grinding chemical raw materials, such as pigments, dyes, coatings, etc.

Mining: used for grinding ores, improving the fineness of ores, and providing suitable materials for mineral processing.

Electronic materials: used for the preparation of electronic ceramics, piezoelectric ceramics and other electronic materials.

Pharmaceutical industry: used for the crushing of drugs to improve the dissolution rate and bioavailability of drugs.
