Raw Ball Mill Grinder Introduction:
As an industrial raw material, powder is widely used in cement
industry, building materials industry, metallurgy industry,
chemical industry, electric power industry, paint industry, rubber
industry, plastic industry, cosmetics industry, etc. The particle
size of conventional industrial powder is 1 ~ 10μm, and 0.1 ~ 1μm
for fine powder, 1 ~ 100nm for ultrafine powder or nano powder. The
particle size by ball mill or vertical mill equipment both can
reach 1 ~ 10μm, each of which has advantages and disadvantages.
Applied Materials:
Copper, magnetite, molybdenite, zinc ore, iron ore, gold, hematite,
fluorspar, lead & zinc, manganese, tungsten, marble, granite, slag,
cement, limestone, clinker, coal etc
The most widely used in the classification of mills, and the most
classic is the ball mill. Ball grinding mill (ball grinding mill)
is the key equipment for crushing materials and then crushing. It
is mainly used in cement, silicate products, new building
materials, refractory materials, fertilizers, ferrous and
non-ferrous metal beneficiation and glass ceramics production
industries. The ball mill can be divided into two types: lattice
type and overflow type according to different ore discharging
methods. It can be divided into dry and wet grinding methods. It is
suitable for grinding various ores and other materials, and is
widely used in mineral processing, building materials and chemical
industry. And other industries.
Working Principle:
Vertical Raw Mill
Vertical raw mill uses pressure and shear generated between the
rollers and the rotating table to crush and grind raw materials.
Feed material is directed onto the grinding table by the feed
chute. The rotation of the grinding table accelerates the material
towards the grinding track and passes it under the rollers. Coarser
material and bigger lumps drops through the nozzle ring – and is
eventually recirculated into the feed material inlet. Moisture
evaporates almost immediately as the gas stream carries the finer
portion of material to the separator. The separator allows material
that has reached the required fineness to leave the grinding mill
and sends oversized material back for further grinding.
Horizontal Raw Mill
The raw mill is a horizontal rotating device transmitted by the
gear. The materials are transferred to the grinding chamber through
the quill shaft uniformly. There are ladder liner and ripple liner
and different specifications of grinding media in the chamber. The
centrifugal force caused by rotation of shell brings the grinding
media to a certain height and impact and grind the materials. The
fine materials are discharged through the outlet, thus the grinding
process is finished.
