Reliable Performance Raw Ball Mill Grinder Simple Structure With
Large Drying Capacity
Ball Mill 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
Working Principle:
The working principle of the two is different. The grinding
principle of the ball mill is that the large particles are crushed
into small particles by the impact between the large steel balls,
and then the small particles are ground by the relative movement
between the small balls To achieve the purpose of grinding, the
ball produced by the ball mill has a better sphericity and a
smoother surface. The working principle of the vertical mill is to
crush and grind large-grain materials directly into fine powder by
the extrusion and shear between the grinding roller and the
grinding disc. The powder produced by the vertical mill is in the
form of flakes under the microscope, and the sphericity is
relatively difference.
Due to the different methods and principles of the ball mill and
the vertical mill, the energy consumption of the ball mill is
generally higher than that of the vertical mill, but this also has
certain limitations. When the particle size of the mill is> 13
μm (about 1000 mesh), the vertical mill is used. The energy
consumption of the mill is lower. When the particle size of the
grinding is less than 13μm, the energy consumption of the ball mill
will be lower. The main reason is that when the vertical mill is
ground, the material is only rolled once by the grinding roller and
the grinding disc. The medium-sized powder produced after rolling
is more, the fine powder is less, and the unqualified by the
separator Because the fine powder is relatively light, it is
difficult to fall onto the grinding disc for secondary grinding, so
the output of ultrafine powder with vertical grinding is lower and
the energy consumption is higher; while the principle of the ball
mill is just the opposite. The number of crushing and grinding is
multiple and uncertain, and there is a certain amount of
over-grinding. Therefore, the proportion of fine powder produced by
the ball mill is also high, and the output is relatively high when
grinding fine powder, and the energy consumption is low.
