Ball Mill Design. A survey of Australian processing plants revealed a maximum ball mill diameter of meters and length of meters (Morrell, 1996). Autogenous mills range up to 12 meters in diameter. The lengthtodiameter ratios in the previous table are for normal applications. For primary grinding, the ratio could vary between 1:1and :1.
The common types of ball mill used in the mineral processing mainly include cement ball mill, tubular ball mill, ultrafine laminating mill, cone ball mill, ceramic ball mill, intermittent ball mill, overflow ball mill, grid ball mill, wind discharge ball mill, double bin ball mill, energysaving ball mill. But the types of ball mill are also varying according to the different sorting conditions.
The ball mill is a typical material grinder machine which widely used in the mineral processing plant, ball mill performs well in different material conditions either wet type grinding or dry type, and to grind the ores to a fine size. Main ball mill components: cylinder, motor drive, grinding medium, shaft. The cylinder cavity is partial filling with the material to be ground and the metal grinding balls.
Jun 14, 2018#0183;#32;The Function of a Ball Mill . To perform its functions, the ball mill operates on the principle of impact and attrition. This principle entails that the balls are dropped from near the top of the shell in order to bring about size reduction impact. The major components of the ball mill include a shell that is hollow and is suspended on its axis to bring about rotation. The axis of the shell can be suspended
Jun 23, 2020#0183;#32;A ball mill is one of the most common equipment items in a mineral processing plant. Its job, to grind rock by tumbling it in a large metal cylinder loaded with steel balls, is highly energy intensive. In fact, the cost of grinding in a mining operation represents a significant proportion of
Comminution (crushing and grinding). Beneficiation (separation and concentration). Smelting and refining. Ball mills are employed in the comminution stage as grinding machines ( size reduction ). The purpose of grinders in the mining industry is to reduce the feed material size in order to liberate the minerals from the barren rock. Ball mills are the most common grinding machine employed in the mining industry.
What is the common problem of the ball mill . Henan Zhengzhou Mining Machinery Co. Ltd. Technology Development Center pointed out that the socalled ball mill quot;common problem quot; is the wear and tear phenomenon of ball mill parts in the using process.

May 11, 2020#0183;#32;Due to the criticality of the pinions on a ball mill, most companies will have a spare available. And this is where the expertise of CBC Australia is so important to hard rock mining
Ball mills are the most common grinding machine employed in the mining industry. Grinding occurs in a single stage, or multiple stages. Multiple stages may include a rod mill followed by a ball mill (two stage circuit), or a semiautogenous grinding (SAG) mill followed by a ball mill (two stage circuit).
