Figure 10.1 shows the difference in energy efficiency between a laboratory ball mill and a stirred mill grinding a gold ore using 6 mm diameter alumina balls as media. At a fine grind size there is a clear advantage in energy consumption for a stirred mill over the tumbling mill. However, as the grind size coarsens, the difference in specific energy required to achieve the grind lessens.
A 10 MW cement mill, output 270 tonnes per hour A cement mill (or finish mill in North American usage  ) is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement .
Rod mills are very similar to ball mills but instead of using grinding balls they use long steel rods to do the media grinding. Some miners believe that rod mills are more efficient than ball mills and that the desired product result is obtained at a lower cost per ton.
The Flat Die Pellet Mill: The image to the right depicts the basic design and process of the flat die pellet mill. A solid metal plate sits below a series of compression rollers. Material enters from above and falls between the rollers, which is then compressed through the die.
The fine grinding mills are classified often into five major groups: (1) impact mills, (2) ball media mills, (3) air jet mills, (4) roller mills, and (5) shearing attrition mills from the viewpoints of grinding machines.

Sep 05, 2018· A grinding mill is a large tubular machine with a crown gear driven by a pinion, which is driven by a reduction gear and electric motor. Some large SAG mills have what we call a "wrapped" motor drive, which is the motor fields are installed surrounding the entire circumference of the mill, with the mill itself being the stator.

A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().
In the last five years, grinding units have increased considerably in capacity, resulting in a trend toward fewer comminution machines per grinding line. Today, 40 ft. diameter SAG mills and 30 ft. diameter ball mills, both with motor powers of more than 22 MW, are commonplace as mine operators look for even larger equipment to achieve greater economy of scale.
Grinding in ball mills is an important technological process applied to reduce the size of particles which may have different nature and a wide diversity of physical, mechanical and chemical characteristics.
A ball mill is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints. Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium.
S. Ramachandra Rao, in Waste Management Series, 2006 220.127.116.11 Recovery of Iron and Iron Concentrate. The first step in slag processing is size reduction to liberate metallic iron and iron-bearing minerals. This is done by crushers or by autogenous grinding, that is, the slag is ground on its own in the grinding mill without any balls.
