Ball mills are widely used in the mining industry for grinding various ores
and other materials. They consist of a horizontal cylinder that rotates on its axis and is partially filled with grinding media such as balls. The material to be ground is fed into the cylinder through a hollow shaft at one end, and the rotation of the cylinder causes the grinding media to fall and impact the material, crushing and grinding it to the desired size. Ball mills can be operated either wet or dry, and are capable of producing fine particles as well as coarse materials.

Rod Mills

Rod Mills use long steel rods to do the grinding. The rods grind the ore by tumbling within the mill, similar to the action of a rotating drum. Rod mills are typically used in mineral processing applications where the ore has a low level of hardness and soft to medium density. They are often used as a primary grinding stage in a larger processing circuit. The product size from a rod mill is typically coarser than that from a ball mill, and is suitable for downstream processing such as flotation.

SAG Mills

SAG (Semi-Autogenous Grinding) mills are large grinding mills that are used in the primary stage of mineral processing. They rely on the use of large steel balls or rods within the SAG mill to grind the ore. The material is fed into the mill through a feed chute and is then ground by the steel balls or rods as they tumble within the mill. The ground material is then discharged from the mill through a discharge screen. SAG mills are often used in conjunction with ball mills, with the ball mill being used to grind the SAG mill overflow material.

Hammer mills

Hammer mills are machines used in material size reduction processes such as grinding and crushing. They consist of a series of rotating hammers mounted on a central shaft within a cylindrical chamber.

The spiral classifier can also be used to wash and remove impurities from ore materials before further processing. The spiral classifier has a simple structure, reliable performance, and easy operation.

Hydro cyclones

Hydro cyclones are a type of classifier that separates particles based on their size, shape, and density using centrifugal force. They consist of a cylindrical chamber with a tangential inlet that generates a swirling flow pattern. As the mixture of particles and water enters the chamber, the heavier particles are thrown to the outside wall due to centrifugal force, while the lighter particles stay near the center and are carried out through the overflow. Hydro cyclones are commonly used in mineral processing operations to classify and concentrate ore and to remove unwanted fines.

Agitation tank

Also known as a mixing tank, is a container used to mix various components in a liquid.

Gravity Separators


Jigs are a type of mineral processing equipment that are commonly used to concentrate ore by separating valuable minerals from the waste rock. The principle of jigging is based on the differences in the specific gravity of the particles being separated. The material to be processed is fed into a jig, where it is stratified by pulsing water, causing the heavier minerals to settle to the bottom and the lighter materials to rise to the top. Jigs come in many different designs and sizes, depending on the specific application and desired outcome.


Shaking tables

Shaking tables are gravity separation devices that use shaking motion and specific gravity differences to separate minerals or other granular materials. They consist of a riffled deck on which the material to be separated is placed, and a shaking motion is applied in a lateral direction. As the material is shaken, the heavier particles are trapped in the riffles while the lighter particles are washed away. The result is a concentration of heavy minerals at one end and lighter minerals at the other. Shaking tables are commonly used in mineral processing to concentrate gold, tin, tungsten, chromite, and other valuable minerals.

Flotation Machine

Flotation machines are devices that are used to separate minerals from each other through the use of flotation, which is a process of separating minerals from each other based on their surface properties.
