5 Motor Classifier Ultrafine Grinding Mill For Precise Powder
Structure of 5 Motor Classifier Ultrafine Grinding Mill:
The reducer of the ultrafine grinding mill system makes the
grinding table rotate. And raw material is delivered into the
grinding house by the belt feeder through the air-block device. As
the grinding table rotate, there will be centrifugal force, which
will move the raw material towards the edge of grinding table. And
the raw material will be ground between rollers and grinding table.
Motor power is transmitted to the ultrafine grinding mill reducer
via coupling. The reducer outputs torque, which makes the grinding
disc rotate circumferentially. It constitutes an important part of
a vertical grinder. Ti is equipped with independent lubrication and
cooling stations, and automatic protection system of oil pressure
and oil temperature. Please refer to its instructions for its
working principle and application method.
With the pressure of the roller, the materials are smashed by
extrusion, grinding and shearing. At the same time, the airflow
will blow the powder up through the classifier, and the coarser
powder will be blocked by the turbine classifier and falls down
onto the grinding table to be reground. And the fine powder will be
collected in the pulse-jet collector. This step repeats until qualified fine powder is discharged. These
constitute the entire grinding process.
The ultrafine grinding mill, with static and dynamic separator, can
produce powder with a fineness range of 325mesh(40μm) to 2500
mesh(5μm). This ultrafine grinding mill can be widely used in
chemical, metallurgy, non-metallic mining industries for grinding
limestone, calcite, marble, calcium carbonate, kaolin, barite,
bentonite, pyrophyllite etc. Ultrafine grinding mill is capable of
providing high qulity filers and additives used in the papermaking,
segments, plastic, rubber, pigment,printing ink, PVC and so on.
Rollers of Ultrafine Grinding Mill:
The ultrafine grinding mill roller device is a pair of
self-aligning roller bearings. Its design has included calculations
of the life of bearing seats. The bearing seal cavity extends the
outside of the shell and has no not with dust-laden gas. Therefore,
a simple skeleton seal can guarantee no entrance of dust into
roller bearings. Grinding rollers are designed with slope
installation and wedge-shaped ring compression; so it is quite
convenient to replace roller sleeves.
Ultrafine grinding mill roller device is mainly composed of fuel
tank, accumulator and connecting pipes and other components. The
pressure device may control the pressure of ultrafine grinding mill
roller automatically or manually during operation and can adjust
the pressure automatically based on material grind ability and wear
conditions of the rollers and disc. By doing so, it can both reduce
consumption and extend the service life of roller sleeves and
liners. At the same time, the buffer effect provided by the
accumulator allows the pressure imposed by the hydraulic cylinder
to have great flexibility and automatic adjustability. If large and
hard debris encountered, the roller may jump to avoid damage to it
caused by excessive load.
Special Features of Ultrafine Grinding Mill:
1. Strong product diversity. Ultrafine grinding mill is equipped
with multi-motor air classifier, which can produce a wide range of
product sizes. There are 30%~70% in the 2μm range, D97=4~45μm;
2. Lower power consumption with advanced design.
3. Narrow particle size distribution and precise 2μm powder content
4. After being improved, rollers, grinding table, diversion systems
and internal circulation systems can greatly improve the grinding
efficiency and improve output by 15%~30% compared to the same type
of domestic products, and can save electricity by 30%~60% compared
to ball mills, etc.
5. With leading grinding equipment technology, the improved grinder
can be operated at low vibration.
