Professional Energy Efficient Slag Grinding Mill Vertical Roller Mill For Slag
Description
【Application field】: grinding and processing of non-flammable and explosive materials with humidity less than 6% and Mohs hardness less than 7 in the fields of building materials, chemicals, metallurgy, coatings, paper making, rubber, medicine, food, etc.
[Applicable materials]: kaolin, barite, fluorite, talc, water slag, lime calcium powder, wollastonite, gypsum, limestone, phosphate rock, marble, potassium feldspar, quartz sand, bentonite, manganese ore and other materials with hardness less than 7 Mohs.
It is an effective way to realize the recycling and reuse of slag to process, grind and pulverize the slag through the large slag vertical mill equipment. The processed slag powder can be used as an important equivalent substitute for cement production, significantly improving the comprehensive performance of concrete and cement products, and significantly reducing the production cost of cement and concrete. At present, it has been used as a new type of admixture for high-performance cement and concrete.
【Working Principle】: the motor drives the grinding plate to rotate through the reducer, the material falls in the center of the grinding plate from the feed inlet, and the hot air enters the grinding plate from the air inlet. Under the action of centrifugal force, the material moves towards the edge of the grinding plate and is crushed by the grinding roller when passing through the circular groove on the grinding plate. The crushed material is carried up at the edge of the grinding plate by the high speed air flow at the wind ring, and the large particles directly fall on the grinding plate for re-grinding. When the material in the air flow passes through the dynamic and static separator, under the action of the rotating rotor, the coarse powder falls on the grinding plate for re-grinding, and the qualified fine powder comes out with the air flow, The product is collected in the powder collecting device. The material containing moisture is dried during the contact with hot gas to reach the required product moisture.

Advantages of HVM slag vertical mill
Low investment cost
HVM slag vertical mill has the advantages of crushing, drying,
grinding, powder separation and conveying, low comprehensive
investment cost, small floor area, 50% of the ball mill, and can be
arranged in the open air, saving construction costs.
Intelligent control
The HVM slag vertical mill production line is equipped with a PLC
fully automatic control system, which can effectively realize
remote control, and is easy to operate and highly intelligent,
greatly reducing labor costs.
Strong drying capacity
The mill can be directly ventilated with hot air, and the moisture
content of the material is up to 15%. No additional dryer is
required, which saves investment costs and energy consumption
costs, and can meet the production requirements of drying and
grinding materials with different humidity.
Reliable operation
HVM slag vertical mill production line can avoid vibration caused
by broken material due to the use of grinding roller limiting
device, and the new grinding roller sealing device is more
reliable, without the need for sealing fan, with better explosion
suppression performance.
Environmental protection and energy conservation
In line with the national environmental protection and energy
conservation requirements, the system is sealed as a whole,
operates under full negative pressure, has no dust overflow, and
the working environment is clean and consumption is reduced, which
is conducive to improving the market competitiveness of
enterprises.
Convenient maintenance, original accessories available
The grinding roller and grinding disc lining plate in the system
are made of special materials. They are produced with original
packaging, with more guaranteed quality, long service life of
equipment, and sufficient supply of accessories in the factory,
which can solve the customer's concerns about the replacement of
accessories in later production.
