Limestone Grinding Vertical Roller Mill For Slag Coal Clinker Cement Pet Coke
Description
Introduction to Limestone Vertical Mill:
Vertical mill is an efficient, energy-saving, and environmentally
friendly drying and grinding equipment widely adopted by Hefei
Hengcheng both domestically and internationally. Based on years of
practical experience, it is researched, designed, and manufactured.
It integrates drying, grinding, powder selection, and
transportation, and has advantages such as wide adaptability, high
grinding efficiency, low power consumption, low wear, large drying
capacity, convenient product fineness adjustment, simple process
flow, low noise, low dust pollution, reliable operation, and
convenient maintenance. In recent years, it has been widely used in
many fields such as cement raw material and coal powder
preparation, power plant coal grinding and desulfurization stone
powder preparation, slag grinding, chemical industry bentonite and
phosphate ore grinding, metallurgy industry, ultrafine grinding
industry, and so on.
The HVM vertical mill is increasingly favored by users for its
excellent quality, advanced process technology, good performance,
and excellent service.
Limestone powder for desulfurization requires a particle size of
250 mesh or 325 mesh (45 μ m) 325 mesh limestone powder has better
desulfurization effect.
Characteristics of HVM type vertical mill
(a) The HVM vertical mill is equipped with a slag discharge port on
the lower shell, which allows difficult to grind foreign objects to
be discharged from the machine at any time. After shutdown, all
remaining materials can also be emptied.
(b) The grinding roller can be flipped out of the mill for
maintenance with the help of a hydraulic flipping roller device,
and replacing easily worn parts only takes three shifts, improving
the operation rate of the mill.
(c) The curved plate sealing structure is used between the grinding
roller and the shell, which has better sealing effect and
durability compared to traditional structures.
Limestone Vertical Grinding Mill Working principle:
The electric motor drives the grinding disc to rotate through the
reducer, and the material falls into the center of the grinding
disc from the feeding port. At the same time, hot air enters the
grinding chamber from the inlet. Under the action of centrifugal
force, the material moves towards the edge of the grinding disc and
is crushed by the grinding roller when passing through the circular
groove on the grinding disc. The crushed material is carried up by
the high-speed airflow at the wind ring at the edge of the grinding
disc, and large particles directly fall onto the grinding disc for
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 onto the grinding disc for re
grinding, and the qualified fine powder is discharged with the
airflow, Collecting in the powder collection device is the product.
Materials containing moisture are dried during contact with hot
gases to achieve the required product moisture.
