Then 5 g portions of the powder were placed in a locally built ball mill (Forziati et al. 1950) running at 1750 rpm. The approximately one liter steel jar was chromium plated and 500 mL of stainless steel balls in. (~ 6 mm) in diameter were employed. This is considered to be a "vibratory" ball mill in contrast to the planetary type.

These are planetary, tumbling, vibratory, and attrition mills. Planetary ball mill. Planetary ball mills are simple and efficient in producing ground/pulverized material.
A mill is a device, often a structure, machine or kitchen appliance, that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many are many different types of mills and many types of materials processed in them. Historically mills were powered by hand or by animals (, via a hand crank), working ...
The thick bowl can handle steel media and heavy loads. These machines keep parts in constant motion for faster finishing than tumbling machines. The clear lid lets you see work in progress and the drain makes cleanup easier. Fill with media and run wet or dry to finish multiple parts at the same time. Machines can be filled to 100% capacity.
Vibratory mills consist of cylindrical or troughlike elastically suspended grinding pipes, which by means of a balanced mass system, are excited to circular vibrations with accelerations Rω 2 (R the radius of the vibratory circle of motion and ω the angular velocity of the unbalanced mass) of up to approximately 10 g — rarely above that. Inside the grinding pipes are grinding media (balls ...
The FRITSCH Vibratory Micro Mill PULVERISETTE 0 grinds your sample through impact and friction by which the mortar vibrates electromagnetically and the grinding material transfers the vibrations to the grinding ball. At the beginning of the grinding, the comminution of the coarse particles is achieved by the impact effect of the grinding ball.
In vibratory ball mills the vessels are subjected to a horizontal, vertical or elliptical arc. Due to sudden changes in the direction the balls inside the vessel are colliding with the wall and each other. In this type of mill usually only a few balls (one to four) and rather simple and small milling jars are utilized. ...
