Vertical roller mill is a powder grinding equipment with mature technology superior performance. It integrates to crush, dry, grind and classifiy with high production efficiency. It can grind the massive, granular and powdery materials into fine powder.
Vertical roller mill is widely used in cement, coal, electric power, GGBS plant and other industry. It is used to grind steel slag, blast furnace slag, fly ash, cement, clinker, coal, calcium carbonate, barite, calcite etc.
Applicable materials: Stone crusher is used for crushing over 120 kinds of rocks, such as limestone, granite, quartz, basalt, river stone, gold ore, iron ore, coal, gravel, aggregate etc. Different final output size could meet your different needs.
High grinding efficiency, larger capacity, low energy consumption. Compared with ball mill, energy consumption is 40%-50% lower.
The whole vertical roller mill system has small vibration and low noise.It is sealed and operated under full negative pressure without dust spillover. So it could realize dust-free workshop.
The vertical roller mill can directly through hot air. Hot air in the vertical roller mill directly contact with material, and dry ability is strong. It doesn't need another dryer to save cost.
The slag material stays in the mill for a shot time. It is easy to detect particle size distribution and chemical composition. The grinding roller can be turned out by hydraulic device to make convenient maintenance operation.
Vertical roller mill is mainly composed of powder concentrator, grinding roller device, grinding disc device, pressurizing device, reducer, motor, shell, etc. The separator is an efficient and energy-saving powder separation device. The grinding roller is a component used to roll and crush slag materials. The grinding disc is fixed on the output shaft of the reducer, which is the place where the grinding roller rolls materials. The pressurization device is a component that provides grinding pressure for the grinding roller and provides sufficient pressure to the grinding roller to crush materials. After being crushed by hammer crusher, the large material becomes smaller and is sent to the storage hopper by elevator, and evenly sent to the distribution board on the steering board through vibrating feeder and inclined feeding pipe. The grinding disc is driven by a motor through a reducer. The material falls from the feed opening onto the grinding plate. The material is driven to the edge of the disc by centrifugal force and crushed into fine powder by roller. Then, the hot air of the nozzle converts the fine powder into efficient classification. The qualified powder is brought to the powder collector through air for collection, and the unqualified powder is sent back for regrinding.
