Vertical Roller Mill
Roller mills are also used for grinding of lignite and hard coals in the systems for pulverized coal mixture preparation at thermal power plants and boilers.
Vertical Roller Mill Manufacturer
The Strommachina brand roller mills are a very reliable, powerful and efficient type of the milling equipment. The unique feature of the roller mills is their multi-functionality: three process operations are combined in this unit, in particular: drying, milling, separation. The roller mills are a 3-in-1 unit. The manufacture of this mill type was mastered by the Strommashina plant rather recently - in early 2000s. However, over the past decade the Strommashina roller mills combined both quality traditions of our plant and gained popularity both in Russia and abroad.
Advantages of roller mills:
- high capacity
- continuous operation
- reasonable price
The application field of the roller mills is rather wide and consists of the intensively developing sectors and industries. This type of mills is used for producing the raw material in cement industry, and for producing fuel for thermal electric power station.
The roller mills produce a coarser product than the ball mills, and usually they operate at a lower sped. Such mills are suitable for both wet and dry milling and are designed for milling different metallic and non-metallic minerals and construction materials of medium hardness.
The main application of the roller mills with a gravitational separator is dust milling of different coal types. The system features the preliminary drying function.
You may reckon on the long-term and efficient operation of our roller mills: they meet the highest requirements. The use of this mill type will simplify the production tasks you set and will allow obtaining excellent results.
Roller mill consists of:
- grinding rolls;
- grinding table;
- electric motor;
- lined body;
- drive shaft.
Roller Mill Working Principle
The process of crushing and grinding of raw materials in a raw material mill occurs due to the pressure and shear forces generated between the rolls and the rotating table.
The rolls are driven via the gearbox and the electric motor, the raw material and hot flue gases are simultaneously fed through the hopper to the mill.
Rotating rolls crush material, the air flow brings the product to the classifier which separates the coarse fraction, which is sent to regrinding.
By configuring the classifier, you can obtain the product which meets the customer requirements. Rolls wear parts segments are made of the heavy-duty crack-free material. They are perfect for hard metal facing.
Segments can be rotated, which means their full width could be used to maximize the service life.
Roller mill power consumption is less than that of other types of mills by 20-50%.
Roller mills combine drying, grinding, and separation processes in the same unit, simplifying the line design. Since a mill operates at a low noise level, it can be installed outdoors. It significantly reduces installation costs and improves working environment.
