What is a ball mill?

Core Definition: A ball mill is a large, industrial-grade grinding machine. Its core principle is to use grinding media (such as steel balls or ceramic balls) contained within a rotating cylinder to impact and abrade the material, thereby grinding it into an extremely fine powder.

Main Applications: TONTEN ball mills are the most core and versatile grinding equipment in modern mineral processing, building materials, chemical, power generation, and metallurgical industries. Whether grinding metal ores like gold, copper, and iron, or producing cement, silicate products, or even fly ash, ball mills are indispensable.

Core Structure:
1. Cylinder: This is a large, rotating cylinder where the grinding process takes place. It is made of rolled steel plates with hollow journals at both ends. Wear-resistant liners are placed inside to protect the cylinder from wear and to elevate the grinding media (steel balls), adjusting their trajectory to improve grinding efficiency.
2. Feed and Discharge Sections:
Feed Section: The ball mill delivers the initially crushed material via a chute or feeder.
Discharge Section: This is where the ground product is discharged. Ball mills are categorized as either "grid" or "overflow" depending on the discharge method.
3. Main Bearing: This supports the enormous weight of the entire ball mill cylinder and the material and media within it. Sliding bearings (Babbitt bearings) are typically used, along with a complex lubrication system. This bearing is the lifeline for stable operation.
4. Drive System: Motor: This provides power and is typically a high-voltage, high-power motor.

5. Reducer: This reduces the high motor speed to the lower speed required by the drum (usually around 10 to 20 rpm).
6. Pinion and ring gear: The reducer drives the pinion, which in turn engages the ring gear mounted on the drum, driving the drum's rotation. This is the most common transmission method.
7. Grinding media: Primarily steel balls of varying diameters, although steel segments are also used. For special requirements (such as avoiding iron contamination), ceramic balls and pebbles may be used.
