Silex lining bricks for ball mills are widely used in industrial applications due to their tight texture and high hardness. The Mohs hardness of silex typically ranges between 7.0-8.0, with a silicon content of up to 99%. This type of lining bricks is ideal for ball mill interiors due to their exceptional wear resistance and durability, with a service life of 3–5 years, depending on the properties of the material being ground.

Classification by Manufacturing Method:

• Hand-made Silex Lining Bricks

During the hand-made process, fragile and less wear-resistant parts are gradually removed through striking. This results in stable properties, reduced fragility, and excellent wear resistance, making hand-carved silex lining bricks highly popular among customers.

• Machine-Cut Silex Lining Bricks

Machine-cut lining bricks are manufactured from silex ore by using large water saws. These bricks feature smooth surfaces, minimal dimensional errors, and are easy to install. They can be secured using adhesives or cement.

Classification by Customization:

• Preformed Silex Stones

Standard silex stones are uniform in size, with thicknesses typically ranging from 11–20 cm. Our standard blocks offer superior flatness, high silicon content, and high whiteness, and are more cost-effective compared to custom-fit silex lining bricks for ball mills. Customers can perform secondary processing as needed before installation.

• Finished Silex Lining Bricks

Custom-fit silex lining bricks are precision-engineered based on the dimensions of the customer’s ball mill. We provide detailed drawings, theoretical weight calculations, and precise processing of components such as feeding inlets. Minimal dimensional errors ensure easy installation according to numbered sequences.

Classification by Shape:

• Standard Silex Blocks

Standard silex blocks are typically delivered as rectangular bricks unless specific customer requirements dictate otherwise.

• Special-Shaped Lining Bricks

Special-shaped lining bricks can be manufactured according to specific customer requirements. For example, trapezoidal lining bricks feature smaller gaps between bricks and the mill wall during installation, extending service life and simplifying the installation process.

Normal Dimensions of Silex Lining Bricks:

Length: 20–35 cm

Width: 15–22 cm

Thickness: 11–20 cm

Other dimensions can be customized according to customer requirements.

By understanding these classifications, customers can select the most suitable silex lining bricks to optimize the efficiency and longevity of their ball mill operations.
