MTM Medium Speed Trapezium Mill
|
Brief Introduction
MTM Medium Speed Trapezium Mill is a leading-world-level industrial
mill. It is designed by our own engineers and technical workers,
basing on industrial mill research of many years and adopting
world-leading-powder processing technology. Our machine adopts
many advantages from numbers of mill all over the world, such
as trapezium’s working surface, flexible connection, roll linked
pressure boost, etc. It has overcome the traditional mill’s
defect completely in application, capacity, fineness, energy
consumption, service life, etc. And it is the ideal substitute
of the traditional mill, such as Raymond mill, high pressure
suspension mill, ball mill, etc. Nowadays, our products have
been widely used in metallurgy industry, electric power industrial,
chemical, building, steel industry, coal industry, etc. And
it has brought large economic benefits to our customers and
the society.
Application:
It is widely used in many industrial fields, such as building,
chemical, chemical fertilizer, metallurgy, mining, nonmetal,
abrasive, bearing materials, ceramic, steel, thermal power,
bricks & tiles, coal industry, etc. It can grind these materials
which are 9 or less on the Meshes scale, and moisture is below
6%., and they should be non-explosive and non-flammable mining
materials. The final size can be adjusted from 30 to 400 meshes
easily. There are thousands of materials our machine can grind.
The typical materials 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.
Working
Principle
Air is driven into the undersurface of the grinding ring and
flows upward, carrying fines to the classifying section. The
classifier allowed the pulverized material to pass and the oversized
particles are drove back to the grinding chamber for further
processing. The whole mill operates under negative pressure
conditions, which can maximize the service life of major mechanica
components. Thus minimizing mill maintenance and plant housekeeping
problems have been solved.

Technical
Advantage:
MTM Medium Speed Trapezium Mill has lots of matchless advantages,
and it adopts the latest national mill patents. It has features
as follows: new designing, reasonable structure, smaller size,
lower energy consumption, longer service life, and less consumption
of wearing parts, higher performance cost ratio, etc. All its
technical performance has reached leading and international
level. Compared with Raymond mill, ball mill, and high pressure
suspension mill, etc, it has these five technical advantages:
1、The
ladder-shaped rollers and rings improve crushing efficiency
greatly. The rollers and ring are designed in the main machine
of an inverted trapezium, which control the material’s slip
velocity between rollers and rings. They can extend the grinding
time, and enhance the crushing effect.
2、The
press springs with balancing and pressurized function and the
forming resilient connection with steady and vibration reducing
function are invented into our machines. The symmetrical roller
assembly is connected by horizontally-placed spring rod. When
the large materials impact one roller assembly, to keep balance,
the radial force will pass to another roller assembly, which
is on the plane of symmetry through spring rod. Under this condition,
the whole device’s bearing is improved to be 40% on the other
mills; and the forming resilient connection can reduce the vibration
and noise, also it can avoid resonance.
3、The
powder classifier adopts high density impeller, which can increase
precision of powder and capacity. It has been proved that: under
fixed spindle speed, to enhance the density of impeller is to
enhance the fineness of final products. In other words, when
the fineness of final product is fixed, the spindle speed of
high density impeller is lower than the low density one. Thus
under the same power, our machine can reduce resistance of air’s
flow, the capacity can be improved more than 50% over the traditional
one.
4、There
is high-efficiency and energy-saving blower installed on our
machine. The efficiency of prismatic blade equipped on the traditional
machine is only 62%, but the efficiency of the energy saving
blower, whose impeller and blade are both stamping, is 85%.
5、There
is convenient impeller adjusting device. The clearance between
housing and ending of powder classifier’s blade also effects
fineness. Our mill is convenient to adjust the fineness.
Construct
The whole set of MTM medium speed trapezium mill consists of
main mill, powder classifier, speed reducer, blower, jaw crusher,
bucket elevator, vibrating feeder, storage bin, bag filter,
pipe and fitting, cyclone powder collector, electric control
cabinet, electric motor, etc.
