RLM Ring Roller MillLarge output and high production
efficiencyWidely used in calcium carbonate (calcite, marble,
limestone, chalk), barite, kaolin, dolomite, magnesite, alumina,
superfine cement, slag, steel slag and other industries.Features
and Advantages:Available D50:1.5~45μmRelying on the grinding roller
orbital revolution and rotation on the grinding ring track to
finish grinding.Compared with Raymond mill or ball mill, the
production efficiency is more than doubled under the same dynamic
conditions,lower operating cost.Large output: grinding calcium
carbonate, the fineness is 10μm, the output can reach 3 tons / hour
or moreGood product fineness index: can reach the fineness of
fluidized bed jet mill, D97: 3 ~ 45μmBuilt-in classifying wheelIt
is equipped with classifying wheel frequency control, which can
adjust the granularity of the product without stopping the
machine.Unique structure of classifying impeller, favorable
classifying effect and no particle pollution.Favorable product
granularity and stability,Ideal equipment for current dry grinding
method to produce non-metallic mineral fine powder such as calcium
carbonate.The complete set of equipment is easy to install and does
not require large civil works.Fine powder can be completely
recycled without polluting the environment.Compact structure and
small occupation.easy to disassemble and cleanLower installation
power, wide application, high cost-performance.Grinding is in
closed system, low dust and noise, clean and environmentally
friendly production process.PLC control system, easy
operation.Particle sizes can be adjusted as needed.Could produce
powder of D97: 3-8μm, and also produce ordinary powder of D97:
10-40μm.Can be used in series with multi-stage classifiers to
produce products with multiple sizes at one time.Explosion-proof
design can be selected to meet the requirements of ultra-fine
grinding processing of flammable and explosive oxide
materials.Working Principle:Roller mills(micro powder roller
mill,fine roller mill,ring roller mill,roller grinding
machine,automatic roller mill,three/four roller/rolling mill) are
mills that use cylindrical rollers, either in opposing pairs or
against flat plates, to crush or grind various materials, such as
grain, ore, gravel, plastic, and others. Roller grain mills are an
alternative to traditional millstone arrangements in gristmills.
Roller mills for rock complement other types of mills, such as ball
mills and hammermills, in such industries as the mining and
processing of ore and construction aggregate; cement milling; and
recycling.Transmission device connects with main shaft. The top of
shaft connects with rotor structure. The rotor structure has
peripheral shaft. Peripheral shaft is installed with roller. When
the main shaft starts to rotate, peripheral shaft rotates too,
which would make the rollers revolve around main shaft and also
rotate round peripheral shaft. The roller would create strong
centrifugal force during the rotation and revolving, and grind
material with stator. The ground material would fall down to the
distribution plate. The distribution plate and the main shaft would
rotate at the same time, and bring material to the round ring.
Under negative pressure, it would go along the distribution ring to
the classifier chamber. Qualified fine powder would go through the
classifier wheel and into the collector, while coarse powder would
fall down back to the milling chamber for further grinding.ALPA is
a rolling mill manufacturer that produces various types of
mills.Technical
