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.
