Brief Introduction
STM Vertical Mill is a new mill of high efficiency
and low consumption, studied by numbers of our
engineers, for solving the difficulty of high
energy consumption in mill industry. It adopts
new grinding principle, new structure, strong
bearing materials, and absorbing lots of technical
essence of mill. Therefore the performance of
our mill indicators are over traditional mill’s
greatly. Especially, it is very efficient for
crushing high hardness and hardworking materials
and it can work under both dry and wet condition.
Our machine has these characteristics: small
metal worn, little dust, simple and firm structure,
and easy maintenance. It is a revolutionary
technical changing in mill industry. It can
bring higher economic benefit to our customers
and it really fulfills the desire of industrial
fields --- high efficiency and low consumption.
It is invented for powder making in the new
time.
Application
|
| Our machine is a widely-used new grinding equipment
of high efficiency and low consumption. It is
mainly used into these areas, such as building,
chemical, chemical fertilizer, metallurgy, mining,
nonmetal, abrasive, bearing materials, ceramic,
steel, thermal power, bricks & tiles, coal
industry, etc. It can chemical fertilizer, metallurgy,
mining, nonmetal, chemical fertilizer, metallurgy,
chemical fertilizer, metallurgy, mining, nonmetal,
abrasive, bearing materials, ceramic, steel, thermal
power, bricks & tiles, coal industry, etc.
It can grind lump materials into coarse powder
(here coarse powder means the mixer of fineness
powder, fineness sand, and medium sand.). There
are thousands of materials can be grinded by our
equipment, and here are some of them and they
are just for you consultation. They are cement
(raw meal and cement clinker), quartz, feldspar,
calcite, gypsum, limestone, dolomite, graphite,
fluorite, aedelforsite, phosphate ore, fused calcium
magnesium phosphate, car amide, electrolytic manganese
metal, ferromanganese, coal, gangue, slag, zirconium,
steatite, granite, orthoclase, marble, barites,
ceramics, glass, etc. All the materials whose
moth’s hardness is under 9.5 grades can be grinded.

Working Principle:
The speed reducer installed on the upper of the main
machine makes central axis rotate through shaft coupling,
and roller hanger rotates with central axis, and rollers
on the hanger roll around the inside of ring. The
materials come into inlet from upper side of machine,
and they fall down onto the dispersing materials plate,
rotating with central axis in two ways, then the materials
are sent into passage between rollers and rings, after
they are grinded into pieces, they are discharged
from the discharge lip.
Technical Advantages
STM Vertical Mill adopts new plaiting，grinding principle
and scientific structure, also it absorbs numbers
of preparing grinding technology. Compared with traditional
machines, such as roller mill, fine crusher, plaiting
device, kinds of impact mill, etc, it has very remarkable
advantages. Really it realized higher efficiency,
lower consumption and environmental protection of
preparing grinding technology
1. New design and new structure.
Our mill adopts medium speed and pressure, repeated
plaiting principle, and its design is unique in mill
industry. The materials fall down by the force of
gravity. When the materials are too hard, all the
parts of rollers and ring will be worn evenly. So
the capacity will not change greatly. Because of this
ingenious design, when the unprintable materials,
such as bolts, pig iron, etc, come into machine, they
would not worn machine. Because it is unnecessary
to equip with cyclone and many other pipes, small
space it will take.
2. After materials are grinded by
STM Vertical Mill, their physical characteristic is
changed greatly and so their grind able characteristic
is improved greatly. The grinded materials become
irregular multiple-unit, and their inside lattice
are already broken. The structure of the organization
is loose, and the final sizes all have haircuts. Thus,
when the materials are grinded for the second time,
the machine is mainly do grinding work not crushing
work, so the capacity of second grinded is improved
greatly.
3. The crushing ratio of final products
of STM Vertical Mill is large. So is the fineness
size. When the large materials are put into STM Vertical
Mill and through sculptured roller and plate, they
are grinded into fineness size by rolling crush, and
then they fall down into space between roller and
plate, and form a material bed. Under the spring device’s
pressure, rollers do numbers flexible extrusion to
material bed and make them become fineness, and the
result is very ideal. The fineness of final products
can be adjusted. Expect producing large quantity fineness
which is smaller than 100 meshes, this mill also can
make materials, which have large haircuts, by numbers
of grinded. The max final size is below 3mm, so it
is easy for second-time grinding.
4. Long service life of easy worn
parts and small quantity maintain. Depending on high
speed rotation, the traditional grinding equipments
do forcing-crush to materials, and the connection
between easy worn parts is direct. Therefore the consumption
of these parts is fast and high. Also there are large
numbers of dusts. As a result, adjustment and maintenance
is frequent, and speed of production is influenced.
This mill’s grind drove to the material bed, which
located between plates and rollers, thus this avoids
direct connection between roller and plate. Not only
can this improve service life of easy worn parts,
but also can reduce pollution to materials greatly
in the grinding process.
5. This machine has these characteristics:
good mechanical property, easy to handle, convenient
maintain, lower consumption, lower working-cost, producing
of both wet and dry materials; new design feature,
simple structure, easy-installed equipment, lower
cost of base equipment and good environmental protection.
