As a kind of high efficiency grinding equipment, vertical roller mill is widely used for grinding various materials with high requirements of fineness and energy efficiency.
The grindability is from easy grinding to difficult grinding, and the grinding
energy consumption is from 4kwh / T to 25kwh / T.
The moisture content of the material ranges from 1% to 25%.
From non abrasive materials to highly abrasive materials.
From non cohesive materials to highly cohesive materials.
Through continuous optimization of structure design, andI company has successfully applied vertical roller mill technology to the grinding system of the following materials, and has accumulated rich practical experience in mill design and grinding system engineering
Preparation and injection system of pulverized coal for blast furnace, rotary kiln
and hot blast stove
Anthracite and coke blending process
Grinding of cement raw materials and clinker
Grinding of granulated blast furnace slag
The material is fed into the center of the rotating grinding plate through the rotary feeder (or sealed weighing feeder) and the feeding trough, and the metal foreign matters are separated from the material before reaching the rotary feeder. Under the action of centrifugal force, the material diffuses to the annular grinding roller table of the grinding plate. After being rolled by the grinding roller loaded by the hydraulic elastic system, it further moves to the edge of the grinding plate. The hot air is evenly distributed around the grinding plate through the air ring, and the milled and to be ground materials are blown up by the air flow at the air ring and dried. During the rising process of the mill, due to the gravity separation, the coarse particles fall back to the grinding plate, and the fine particles are carried to the separator by the air flow.
With the help of the separator blade, the material is divided into coarse powder and fine powder. The coarse powder falls back to the grinding plate for regrinding, and the fine powder flows out of the mill along with the gas and is collected in the powder collecting device of the system, which is the qualified product.
