Energy Efficient Vertical Roller Mill For Limestone Slag Grinding Mill
Description
With the further expansion of industrial production scale such as iron and steel and metallurgy, slag, blast furnace slag, steel slag, copper slag, manganese slag, phosphate slag, fly ash, coal gangue, quicklime slag, vanadium-titanium slag, lead-zinc slag, etc. The discharge of waste increases year by year. In order to improve the secondary recycling value of industrial solid waste and help turn solid waste into treasure, Hefei Hengcheng Technology has devoted itself to research and carefully developed HVM series vertical mills for industrial solid waste special mill equipment. , with the advantages of energy saving and noise reduction, production and efficiency improvement, and tailor-made selection schemes, it helps industrial solid waste to be transformed into a gorgeous, and expands the value of recycling.
【Use Of Slag Powder】
80% blast furnace slag is washed into water-quenched slag, and the
slag fine powder processed by the slag vertical mill is mostly used
as the raw material of cement mixture and clinker-free cement, and
a small part is used to produce slag bricks, tiles, etc. Slag can
also be used as road slag, railway slag and concrete aggregate, and
a small amount is used to produce slag wool, expanded slag beads,
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 it passes through the annular groove 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 milled 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.

【Product Advantages】
Low Investment Cost
HVM slag vertical mill has the advantages of crushing, drying,
grinding, powder separation and conveying. The comprehensive
investment cost is low, the floor area is small, which is 50% of
the ball mill, and it can be arranged in the open air, which saves
the construction cost.
Intelligent Control
The HVM slag vertical mill production line is equipped with a PLC
automatic control system, which can efficiently realize remote
control, easy to operate, and has a high degree of intelligence,
which greatly reduces labor costs.
Strong Drying Ability
The mill can be directly ventilated with hot air, and the moisture
content of the material is as high as 15%. There is no need to
configure a dryer, which saves investment costs and energy
consumption costs, and can meet the production needs of drying and
grinding materials with different humidity.
Reliable Operation
The HVM slag vertical mill production line adopts the grinding
roller limiting device, which can avoid the vibration caused by the
material cut off, and the new grinding roller sealing device has
more reliable sealing, no need to seal the fan, and better
explosion suppression performance.
Energy Saving
In line with the national environmental protection and energy
saving requirements, the system is integrally sealed, fully
negative pressure operation, no dust spillage, clean operating
environment and reduced consumption, which is conducive to
enhancing the market competitiveness of enterprises.
