Application
of vertical
roller grinding mill: Vertical
roller mill are
suitable for huge capacity producing, widely used in grinding
non-flammable and non-explosive materials under 9.3(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.
Working Principle
of vertical roller grinding
mill: The grinding disc is
driving by motor through reducer. The material falls to grinding
disc from the feed opening. The materials are driven to the edge of
disc by the centrifugal force and crushed into fine powders by
rollers. Then, the hot air from the nozzle take the fine powder to
high effiency classsifer.The qualified powder are taken by the air
to the powder collector to be collected, while the unqualified
powder are sent back for
regrinding.
Advantages
ofvertical
roller grinding
mill:
1. High grinding efficiency: save 20~30% power consumption compared
with the ball mill. With the increasing of moisture content, it can
save more and more electricity.
2. Strong drying capacity: dry and grind raw materials with
moisture content as much as 15%.
3. Mutifunction: crushing, drying, grinding, separating and
conveying.
4. Low noises and little dust: no direct contact between the
grinding rollers and grinding disc, so metallic impact is avoided
and its noises is 20~25 decibels lower. Totally closed negative
pressure operation has employed by this vertical grinding mill, so
there is no dust during the operation.
5. Low wear rate and little metallic pollution: its metal wear is
only 5~10g/t.
