Product Description
MTW series European technology trapezium mill can be used to
process limestone, calcite, marble, talcum, barite, gypsum, lime,
coarse whiting, attapulgite, dolomite, coal, feldspar, quartz,
graphite, coal gangue, fluorite, slag, cement clinker, bauxite,
kaolin, cement, activated carbon, petroleum coke, coal ash, iron
oxide red etc. OBM series European technology trapezium mill is the
lastest grinding mill, which absorbs the European advanced
technology and many engineers’ ripe experience.
Features
1.Bevel gear overall drive: traditional grinding mill is driven by
speed reducer and coupling. It is hard to be installed. And there
will be too much noise, and the efficiency is lower. OBM series
mill is driven by bevel gear, so its structure is compacter, more
efficient and easier to be installed.
2.Inner automatic Thin-Oil lubricating system: the traditional mill
adopts grease lubrication, so the lubricating resistance is
stronger, the temperature will become high soon, the service life
of the bearing is shorter. OBM series mill adopts inner L.O.pumps,
so the main shaft bearing and bevel gear can be lubricated without
additional lubrication system with good stability and
reliability
3.Arc air channel: all air channel of traditional grinding mill is
upright board type. In this case, there will be stronger resistance
when the air impacts the air channel board, and the energy of
collisions of air molecules loss heavily, as a result, the air
channel will be jammed easily because of the eddy air flow. OBM
series mill adopts a cambered air channel, the tangential air goes
into air channel easily because there is little resistance. And the
inner outlet is very good for the grinded material to spread around
and avoid grinding material being jammed.
4.Cambered shovel with renewable edge: The traditional shove is
integral and the edge is always worn out quickly, so you have to
replace it in short time, which affects the working time and wastes
too much steel. The shovel edge of OBM series mill adopts high
wearable limit alloy, its life will be longer. You only want to
change the edge, not the whole shovel. so the steel material is
saved. In addition, because the traditional shovel is plane type,
the grinded material stacks on the same plane when it is scooped
up. So the middle parts of the roller is worn out heavily. But the
cambered shovel can scoop up the grinded material in the same
vertical plane, which makes the rollers and ring worn equally. At
the same, the grinding efficiency is higher and capacity is higher
with good product particle size
5.No resistance snail shell (small checking door so that there is
not an eddy air flow): In the traditional grinding mill, the
checking door of snail shell is prominent, which means the checking
door and snail shell are not on the same plane. So there will be
eddy air flow easily come into being. As a result, the energy waste
is bigger. OBM series mill make the inner surface of checking door
stay with the inner surface of snail shell on the same plane, so
the eddy air flow is avoided efficiently;
