The application
layer crushing mechanism of higher Pressure Roller
grinding machine created on the planet at present is employed in nonferrous
mine, oxidation pellet broken grinding common equipment, it truly is in current
years within the cement with roller machine according to improvement of new
grinding gear. Given that it has higher efficiency,Mobile jaw crusher energy
saving substantial investment, hassle-free upkeep, province and the benefits of
working environment, the globe recognized as the advanced crushing grinding
gear, and all through the world to acquire the swift promotion application.
1 higher
pressure roller structure
Higher Pressure Rolls
grinding machine is mainly by the following parts: two level set and at the
synchronization extrusion roller device of 4 extrusion vice, a single of which
is the fixed roller, the other by way of hydraulic method and to supply the
hydraulic cylinder pressure promote activities just before and right after
roller small scope mobile, the roll and bearing the composition in the two sets
of extrusion roller, by means of the orientation device installed within the
box kind structure are composed of three frame, each extrusion roller have
their very own independent structure from the identical transmission
device,Magnetic drum separator and through the universal shaft coupling, and
hydraulic coupler or security clutch and planetary gear reducer drive technique
composed of 1 to transport the energy rolls, material through the adjustable
feeding device into two rolls of 2 between material cavity. Central for the
gear, the automatic lubrication method of the bearing the technique to provide
the grease. Higher pressure roller manage part mostly in line with the test the
system to supply the signal, the automatic handle method for monitoring gear,
the handle can be divided in to the machine, web site, central handle three
manage mode.
2.1 units
grinding low energy consumption,Magnetic drum separator high production
efficiency due to higher stress roller make full use of the laminated broken
functioning mechanism, the power utilization rate is extremely high, with all
the standard extrusion type super finely crusher and compared grinding machine,
crushing probability and grinding characteristics has improved, mainly may be
the get in touch with point amongst particles and forces far more strong.
2.2 it can
handle high water content of material grinding method or traditional finely
crushing wet material should 1st will dry material, or use wet ground. Drying
is really a large power consumption of the method along with the wet grinding
goods have to precipitate and filtering. But for high pressure roller grinding
machine for, roller components containing a few of the top in the water (much
less than 10%), not just can make a better because birth roller fabric cushion,
but also increase the operating life of extrusion roller. The at present employed
hard alloy column nail roller surface not only tiny abrasion, and roller
surface life can attain 7 000 ~ 30 000 h.Magnetic drum separator
two.3 increase
follow-up function solution grade and recovery
In high stress
beneath the function of grain of group on the supplies inside the particles in
the interior, and mineral and the waste rock about the interface in between the
local pressure produced numerical range, particle components in the bear the
potential of these stress, decided to it have been shattered or happens only
deformation. In the therapy from the diamond, the difficult mineral take these
tension and diamond about the rock is shattered. In coping with the mine,
ZhouYan were shattered, and gold content fundamental integrity or create a little
deformation. For sulfide ore deposits or, due to the nature on the differences
between the mineral composition of the interface come about pieces, and boost
the mineral disintegrate degrees.Shaking concentrator In oozy homework,
particle surface and particles of cracks and crevices inside exudate can
infiltration, so as to improve the product grade and helpful mineral recovery.
2.4 covers an
area of less, the investment province
High pressure
roller grinding machine since the structure is compact, gear light weight,
characteristics of modest size, its installation position covers an region of
less. Because of the grinding effects mainly within the interaction amongst the
two rolls of pressure, produced mostly by the impact extrusion frame, assume,Shaking
concentrator around the basic in the load is small, so the grinding machine
with compared, can save a large number of standard investment.
two.5 production
environments is great
From high
pressure roller principle of work can see, the usage of laminated crushing
mechanism, and also the material is sealed in rolls and feeding device in the
enclosed space, broken by static stress, general will not influence and
material splash, so gear vibration and noise is low,Shaking concentrator
enhance the operating atmosphere.
3 high stress
roller application
The early 1990
s, the world sector developed countries, like Germany, the Usa, Brazil, Russia
and other countries within the mineral processing industrial region, for
example higher pressure roller study and application, has effectively with high
stress roller grinding machine for diamond disintegrate, valuable metals ore
dressing, base metal ore dressing and preparation material, the pellet
projects, and have accomplished outstanding economic and social rewards.
Higher pressure
roller used in pellet feeding of iron concentrate grinding approach technique,
regardless of in the production efficiency and production high quality,
financial benefit and social benefit on appear, than the embellish is superior
a great deal, so, in the processing market, higher pressure roller grinding
machine replace embellish will will be the trend in the Times
