Vertical roller mill manufacturer - SMMVIK
What are vertical roller mills?
Vertical roller mills are industrial milling machines that are used to break down material into smaller pieces. There are several different types of vertical roller mills, each with its own unique design and features. Although they may look similar on the outside, they function differently on the inside.
The most common type of vertical roller mill is the ball mill. Ball mills use a rotating cylindrical shell filled with steel balls to crush the material. The material is fed through a hole in the shell and grinded by the steel balls as they rotate. The ball mill can be used for both wet and dry grinding, and can be very effective for breaking down tough or hard materials.
Another type of vertical roller mill is the rod mill. Rod mills use long metal rods to grind the material. The material is fed through a hole in the center of the rod and ground by the rotating rods. Rod mills are less common than ball mills and are not as effective for breaking down tough or hard materials.
Vertical roller mills are very versatile and can be used for a variety of applications. They are commonly used in cement plants, but can also be used in other industries such as mining, power generation, and chemical processing.
How do vertical roller mills work?
Vertical roller mills are frequently used in the cement industry and power generation, because they are capable of achieving high rates of production while using less energy than other types of mills. How do vertical roller mills work?
The material to be ground is fed into the mill from the top and falls onto the grinding table below. The rotation of the grinding table causes the material to be drawn up through the rollers and crushed as it passes around them. The material is then blown out of the mill by a fan and collected for further processing.
The benefits of using a vertical roller mill
Vertical roller mills offer many benefits over traditional ball mills. Including:
1. Increased grinding efficiency – thanks to the unique design of the mill, material is fed into the grinder at a constant rate, meaning that there are fewer complaints of inconsistent grind size.
2. More energy-efficient – vertical roller mills use up to 50% less energy than ball mills, meaning that operators can save on their energy bills.
3. Low noise and dust pollution – because the vertical roller mill grinds material using a completely enclosed system, there is very little noise or dust pollution generated during operation.
4. Reduced maintenance costs – thanks to the simple design of the vertical roller mill, there are fewer moving parts requiring regular maintenance and servicing.
The different types of vertical roller mills
Vertical roller mills are classified into three main types, according to their source of energy:
1. Thermal power plants: These use coal or other fossil fuels as their source of energy. The advantage of these mills is that they can be easily integrated into existing power plants.
2. Geothermal power plants: These use the heat from the Earth's interior as their source of energy. The advantage of these mills is that they have a very low environmental impact.
3. Hydroelectric power plants: These use waterfalls or other moving water sources as their source of energy. The advantage of these mills is that they are very efficient and have a very small environmental impact.
