Energy Saving Mining Limestone Grinding With Vertical Roller Mill
Description
【Scope of Application】
calcium carbonate pulverization, gypsum powder processing, power
plant desulfurization, non-metallic ore pulverizing, pulverized
coal preparation, etc.
【Materials】
limestone, calcite, calcium carbonate, dolomite, barite, talc,
gypsum, diabase, quartzite, bentonite, etc.
【Working Principle】
The motor drives the grinding disc to rotate through the reducer,
the material falls into the center of the grinding disc from the
feed inlet, and the hot air enters the mill from the air inlet.
Under the action of centrifugal force, the material moves to the
edge of the grinding disc, and is crushed by the grinding roller
when passing through the annular groove on the grinding disc. The
crushed material is carried by the high-speed airflow at the air
ring at the edge of the grinding disc, and the large particles fall
directly on the grinding disc. Re-grinding, when the material in
the airflow passes through the dynamic and static separator, under
the action of the rotating rotor, the coarse powder falls on the
grinding disc for re-grinding, and the qualified fine powder is
ground together with the airflow and collected in the powder
collecting device, which is product. Moisture-containing materials
are dried during contact with hot gas to achieve the required
product moisture.

Re:The data based on Mohs'hardness 3-4 material
Limestone Bond Index≤13kwh/t
【Characteristics】
1. High efficiency and energy saving: under the condition of the
same fineness and motor power, the output is more than double that
of jet mill, stirring mill and ball mill.
2. Long service life of wearing parts: The roller sleeve can be
turned over for use, which prolongs the service life of
wear-resistant materials.
3. High safety and reliability: because there are no rolling
bearings and no screws in the grinding chamber, there is no problem
that the bearings and their seals are easily damaged, and there is
no problem that the screws are easy to loosen and damage the
machine.
4. High product fineness: The fineness of grinding products can
reach 325 meshes at one time.
5. Environmental protection and cleanliness: The pulse dust
collector is used to capture dust, and the muffler is used to
reduce noise, which has the characteristics of environmental
protection and cleanliness.
