Vertical roller mill 1) Introduction to the Vertical roller mill STM Vertical roller mill is a kind of grinding mill with high-effcient and low energy-consumption after years’ design and development by China Mining Equipment Co., Ltd . .And to resolve some technology problem, we company have organized the first-class expert to concentrate on them. And the Vertical roller mill adopt novel powder grinding principle , reasonable structure design ,high anti-abrasion alloy materials and multi-powder grinding mill technology with its every performance over traditional powder grinding mill .And the Vertical roller mill
have better crushing effect to the materials with high-hardness and difficult
processing with two kinds of manufacturing with or without moisture. And with low energy-consumption, low dust emission, simple and solid structure ,convenient maintenance and operation ,the Vertical roller mill is a technology breakthrough in the industrial grinding area, which
can
bring
bigger
economic
benefits
and
realize
energy-consumption .And at present ,the Vertical Vertical roller mill
high-efficient
and
low
have opened up the new era in the
industrial powder manufacturing. manufacturing.
2)
its
working principle princip le of Vertical roller mill
The
reducer
installed on the top of main units will be connected with the central axis to rotate by the couplings .And the central axis will drive
the
grinding
roller cradle to rotate and the roller will be installed
on
the
cradle to proceed the rolling along with the inner grinding mill .And the materials will be entered the feeding hopper from the side top of the machine and then be scattered around the distributing plate rotating with the central axis .And then the materials will be evenly entered the space between the grinding ring and roller and then be discharged out by the outlet after the grinding and crushing.
3) Application of Vertical roller mill
Vertical
The
roller mill is a new kind
of
grinding with
powder equipment
high-efficient
and wide application and can be widely applied in the field of building chemicals, metallurgy,
materials, fertilizer, mining,
nonmetal, abrasive, refractory, ceramic, steel, thermal power, bricks, coal, etc. And the Vertical roller mill can also be used to grind the block materials into the coarse powder( mixture of fine powder, medium and fine sand ) such as cement (raw clinker), quartz, feldspar, calcite, gypsum, limestone, dolomite, graphite, fluorite, wollastonite, rock phosphate, calcium magnesium phosphate, coal gangue, slag, zircon sand, talc, granite, K-feldspar, marble, barite, ceramics,
glass ,etc. And these materials has the Mohs hardness of below 9.5 degree with high, medium ,and low hardness.
4) technical features of Vertical roller mill
The Vertical
STM roller
mill
adopt novel principle of
roller
pressure
powder grinding and the scientific design. And the Vertical Mill have also absorbed multi-pregrinding technology and have the
prominent
advantages than the traditional Vertical roller mill, mill , fine crushing mill, roller pressure and other kinds
of impact
crusher
,which
have
really
realized
the
pregrinding
technology’s
high-efficiency ,energy-saving and environment-friendly environment-friendly.. 1

Vertical roller mill adopts the principle of medium speed and pressure grinding .With the
reasonable design, the materials can freely fall down from top to bottom and the powder materials with high hardness and hard processing will receive the same wearing degree from every part of the grinding roller .With the reasonable design, the Vertical roller mill will receive no harm when some anti-grinding materials enter the machine and these materials are mainly including some bolts and iron blocks. And the Vertical roller mill do not need to be equipped with other cyclone classifier and pipes with the small occupation area. 2
、
The materials the Vertical roller mill have processed will receive the physical properties
change and the grinding advantages will become more prominently. And the grinding materials will appear the irregular multi-rhombus and the inner crystalline lattice have been destroyed and the organizational structure have become loose .And the grinding materials all have slight crack and such materials will produce the crushing burden and the function have tends to be the grinding when the second grinding proceed. So the production of the second powder grinding have been greatly improved . 3
The final products features large crushing ratio and high fineness .And when the large-size
、
materials enter the Vertical roller mill , they will receive the rolling crush to become the fineness and then fall down to the space between the rollers and plates ,which will form the materials bed by the dimple gear of the grinding roller and plate. And during the spring pressure, the grinding roller will make more than 10 times soft extrusion to make the materials become the powder on the materials bed , and the grinding effects is very good. And the fineness of the products can be adjustable, and Vertical roller mill can produce the fine powder of less than 100monyh.And the particle size will receive multi-grinding to produce large slight crack and the biggest size can be controlled at the range of less than 3mm,which is more easy to the second powder grinding. 4
、
With long service life ,small maintenance, Vertical roller mill
has many features .And the
traditional grinding equipment will depend on the high-speed rotating to proceed the forcely cutting to the materials and the wearing parts will produce the direct collision ,thus producing the fast wearing parts ,high consumption and large dust pollution. So all o f these will result in the frequent maintenance and adjustment ,thus influencing the normal production. Vertical roller mill proceed the grinding is the extrusion to the materials layer .And the grinding roller will make the revolution and rotation, thus avoiding the direct collision between the roller and plate .And all of these have not only improved the service life of the wearing parts but also greatly reduce the pollution the mechanical equipments brought to the processing powder . 5
The STM Vertical roller mill features better mechanical performance ,simple operation,
、
convenient maintenance, low wearing parts and long service life and can proceed the manufacturing with or without the moisture. And with reasonable structure , simple structure, convenient installation ,the Vertical roller mill can save the investment cost with low noise and dust pollution ,and better environment-friendly effects. effects.
