Brief Introduction of Vertical Roller Mill
CLUM Vertical roller mill is a new type of milling equipment that
includes grinding, grading, conveying, secondary powder selection,
and finished product packaging.
It is a large-capacity ultra-fine grinding and separation equipment
developed by SBM, based on its 30 years of research and operation
experience in the grinding industry.
CLUM Vertical roller mill is suitable for the production of fillers
and coating calcium carbonate in large paper mills and the
processing of other large-volume ultra-fine powders.
Applications of Vertical Roller Mill
Vertical roller mills are widely used in chemical, metallurgy,
non-metallic mining, and other industries. It suitable for huge
capacity producing, widely used in grinding non-flammable and
non-explosive materials under 7(the Moh’s hardness). Such as
quartz, feldspar, calcite, talcum, barite, fluorite, iron ore,
copper ore quartz, especially for slag, cement clinker, zircon
sand, fly ash and carborundum, coal, etc.
Features of Vertical Roller Mill
1 High production capacity
2 Advanced control system
3 Special wearable alloy materials
4 Strong drying capacity: drying and grinding raw materials with a
moisture content of up to 15%.
5 Environmental protection
Vertical Roller Mill Working Principle
The grinding wheel is driven by a motor through a reducer. The
material is fed into the main machine of the vertical roller mill
through the feed screw and falls into the center of the grinding
Under the action of centrifugal force, the material spreads from
the center of the grinding disc to the surroundings and is rolled
into fine powder.
The powdery material continues to move to the edge of the grinding
disc until it is taken away by the strong airflow from the air
inlet and enters the high-efficiency classifier. The qualified dust
is collected by the integrator, and the unqualified dust is sent
back for regrinding.
Advantages of Vertical Roller Mill
1. Good quality of finished products: Finished products have high
whiteness, fine particle size, narrow particle size distribution,
and good particle sphericity. The fineness D97 of the finished
powder can reach 3000 meshes, and the content of 2m can reach up to
2. High grinding efficiency: save 20~30% power consumption compared
with the ball mill.
3. Strong drying capacity: dry and grind raw materials with
moisture content as much as 15%.
4. Multifunction: crushing, drying, grinding, separating, and
5. Low noises and little dust: no direct contact between the
grinding rollers and grinding disc, so metallic impact is avoided,
and its noises are 20~25 decibels lower. Totally closed negative
pressure operation has been employed by this vertical grinding
mill, so there is little dust during the operation.
6. Low wear rate and little metallic pollution: its metal wear is
only 5~10g/t.Low wear rate and little metallic pollution: its metal
wear is only 5~10g/t.
Industrial ultrafine vertical roller mill customer case
-calcium carbonate ultrafine powder production line
CLUM series ultrafine vertical roller mills have a large capacity,
stable operation, low wear, long life, environmental protection and
energy saving, simple operation, intelligent control system, easy
maintenance, and the fineness can be freely adjusted between
The fineness of the calcium carbonate powder produced can reach
3000 meshes. The finished powder has high whiteness, good powder
ball shape, high 2um fine powder content, and more fine powder
content. It is a high-end powder without iron, especially suitable
for high-end coatings, papermaking, and other fields.
