Ball mill（Dry/Wet）:Crushing

Main specifications

Type	Average particle size	Operation system
Dry	～ 5μm	Batch milling
Wet	～ 5μm	Batch milling

A fine milling, applicable to a wide range of fields

Features

A fine milling machine in which raw material and ball media such as ceramics are fed into a
horizontally rotating drum, and milling is carried out by collision with ball media and by crushing
and its impact with the media and drum inner wall surface.
Various types of lining materials are available, making it possible to suggest the most suitable
specifications for raw materials.
We also suggest milling media depending on the purpose of use.
Simple structure and easy to maintain.

Rotating speed

Rotating speed (N) differs, depending on the size of mill and meling media, whether or not there are
inner lifting bars, type of milling; dry or wet. In general, optimum speed is represented by the
ratio (N/Nc) for critical speed (Nc). Critical speed (Nc) is a rotating speed of the time when milling
media is crimped on the wall of the mill by centrifugal force while mill speed is being increased.

Rotating speed：
N<<Nc（Surging condition）

N<Nc
（Cataracting condition）

N＝Nc
（Critical condition）

Calculate rotating speed at milling media ⌀30mm, Dry type 75%. Wet type 65%.
●for dry type……N ／ Nc×100＝70 ～ 80％ ●for wet type……N ／ Nc×100＝60 ～ 70％

Milling type

Dry milling

Only material and milling media are
fed into the drum.
Less contaminant from liners and
milling media.

Wet milling

Material and milling media are fed
into the drum with water or organic
solvent.
Suitable to mix and compound
materials.
