Ball mills scale up well and in fact improve in performed with increasing size. Ball mills are available in sizes from laboratory scale (also called milling jars) of 0.1 usg to large 5,000 gallon mills. Ball mills are available in various contact materials to accommodate contamination and wear requirements.
11-01-2016 Several types of ball mills exist. They differ to an extent in their operating principle. They also differ in their maximum capacity of the milling vessel, ranging from 0.010 liters for planetary ball mills, mixer mills, or vibration ball mills to several 100 liters for horizontal rolling ball mills.
Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.-% ore and 25% steel. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones.

Tumbling ball mills or ball mills are most widely used in both wet and dry systems, in batch and continuous operations, and on a small and large scale. Grinding elements in ball mills travel at different velocities. Therefore, collision force, direction and kinetic energy between two or more elements vary greatly within the ball charge.
A ball mill, a type of grinder, 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. Different materials are used as media, including ceramic balls, flint pebbles, and stainless steel balls.

A ball mill for use in mechanical alloying and grinding comprising a plurality of ferromagnetic balls (22) within a spherical or generally cylindrical chamber or cell (20) of a paramagnetic material. The cell has a substantially horizontal axis of rotation (21). At least one magnet (24) is mounted outside the chamber to produce a magnetic field within the chamber.

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 ().
ball mill is used. ... Size reduction or comminution is among the most comprehensively used unit operation of widespread application in chemical and other related industries.
Vibration mills are similar to ball mills in that particles of the materials are crushed between porcelain or metal balls and the mill body. Drugs and excipients are readily ground to less than 5 mm, the grinding time being considerably less than is required in normal ball milling.
Ball Mill Operation. Ball mills ride on steel tires or supported on both ends by trunnions. Girth gears bolted to the shell drive the mill through a pinion shaft from a prime mover drive. The prime movers are usually synchronized motors. During rotation, a portion of the charge is lifted along the inside perimeter.

Method of Operation. The mill incorporates a yoke and locking mechanism to facilitate easy access to the contents of the mill. An appropriate ball or rod charge is provided with the mill. The motor incorporates a solid-state controller to accurately control the drum speed of up to 70 RPM. This controller has an internal overload protection.
