Ball Mill

MoleDive, China’s leading manufacturer of ore and mineral ball mills.

MoleDive Ball Mill Manufacturer, this ball mill is of the horizontal type and is used for grinding stone or materials into fine powder or mixtures.

The ball mill consists of main parts including the feeding part, discharging part, rotating part, and the transmission part (reducer, small transmission gear, motor, and electrical control). The hollow shaft is made of cast steel, and the inner lining can be replaced, ensuring excellent performance and high processing capacity of the large gear on the main shaft.

MoleDive ball mills are mainly used in the fields of mining, metallurgy, chemical engineering, and construction materials for grinding ores and material mixing.

FAQ Guide of Magnetic Separator

1. What is the ball mill?

This machine is a horizontal cylindrical rotating device, with external gear transmission, two chambers, and a grid-type ball mill. The material is evenly fed into the first chamber of the mill through the feeding device via the hollow shaft spiral. This chamber is equipped with stepped or ripple liners and contains steel balls of different specifications. When the cylinder rotates, it generates centrifugal force, causing the steel balls to rise to a certain height and then fall, producing heavy impacts and grinding effects on the material. After coarse grinding in the first chamber, the material enters the second chamber through a single-layer compartment board. This chamber is lined with flat liners and contains steel balls for further grinding. The powdered material is discharged through the discharge grating plate, completing the milling operation.

2. What is the difference between a ball mill and a rod mill?

Both ball mills and rod mills are used to grind ores and minerals, but they operate and are applied in different ways.

Abrasive Media:

High-chrome or forged grinding media, which is spherical in shape and offers more surface area for grinding, is used in ball mills.

Long rods are used as the grinding media in a rod mill, which is more efficient in dissolving bigger particles and producing a coarser end product.

Material Size for Grinding:

Ball mills: Frequently used for mixing and fine grinding, they may grind materials down to the nanoscale range.

Rod mills: Typically used for processing bigger materials and coarse grinding, they can grind materials to a depth of millimetres or centimetres.

Application:

Ball mills are frequently used in sectors such glass ceramics, ferrous and non-ferrous metal beneficiation, cement, silicate products, new building materials, refractory materials and fertilisers.

Rod mills are frequently used for coarse grinding or to prepare feed for subsequent processing steps in the mining, metallurgy, chemical engineering, building materials and other sectors.

Operating Theory:

Ball Mill: This device grinds materials by rotating a cylinder that contains grinding media and the material to be ground. As the media strikes the substance, a cascade effect is produced.

When cylindrical rods rotate along the length of the mill, the material is raised up and subsequently broken apart by a cascade of downward forces.

A grinding chamber’s shape:

Ball mills: Generally speaking, they have cylindrical chambers, though there are other variations.

The length to diameter ratio of a rod mill’s longer, cylindrical chamber is typically 1.5 to 2.5.

Discharge:

The discharge end of a ball mill, which often has a grate to regulate the product size, is used to discharge material.

Rod mill: Can produce a coarser output by discharging material via both the end and periphery apertures.

3. What is horizontal ball mill?

A horizontal ball mill is a type of grinder used in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering to grind or blend materials. It operates on the idea of impact and attrition: as the balls fall from close to the top of the shell, size reduction is accomplished by impact. A cylindrical shell that is hollow and rotates about its axis makes up a horizontal ball mill. The shell’s axis could be horizontal or at a little inclination to the horizontal. The material to be ground is placed into the shell, which is then partially filled with balls or other grinding medium. The material is impacted and ground as a result of the shell’s rotational movement of the grinding media. Through a discharge port, the finished product leaves the shell. Horizontal ball mills are frequently used in several industries for material grinding and blending.
