Cement is an indispensable building material in the construction industry, and the production of cement is inseparable from a series of processing equipment. Among them, the Hanging Roller Mill plays a vital role in cement production. Next, let’s delve into the role of the Hanging Roller Mill in the cement production process, its working principle and its criticality in improving production efficiency and quality.
Hanging grinding mill
Hanging Roller Mill, also known as vertical mill, is a common cement grinding equipment. Compared with traditional horizontal mills, suspended mills use vertically arranged grinding discs and drums that operate by hanging on a shaft. This design makes the Hanging Roller Mill more adaptable and productive in cement production.
Working process of Hanging Roller Mill
The first step is to feed. The first step in cement production is to feed raw materials into an overhead mill. These raw materials usually include limestone, earth, iron ore and other auxiliary raw materials. This process also requires the use of some auxiliary equipment, such as belt conveyors, feeders, etc.
In the second step of the grinding process, the stone raw materials are placed on the grinding disc from above, while the rolling roller exerts pressure on the grinding disc. Due to the action of the high-speed rotating grinding discs and rollers, the raw materials are compressed, rubbed and ground in the vertical direction.
In the third step, hot air enters. In order to speed up the grinding process, hot air is sprayed into the grinding mill from the bottom, making it easier to grind the raw materials in a high temperature and high pressure environment.
The fourth step is separation after grinding. The ground materials enter the separator through air flow. The separator separates the ground fine powder through aerodynamic principles to ensure that it meets the particle size requirements required for cement production. This process requires the use of vital auxiliary equipment, vibrating screens, etc.
The final step is to produce the finished product: the fine powder separated by the vibrating screen enters the dust collector and is collected, while the remaining larger particles return to the grinding disc for secondary grinding. Ultimately, the raw material processed through the suspended mill becomes the key component of cement.
Advantages of using Hanging Roller Mill for cement production
Advantage one: efficient grinding. The vertical arrangement design of the Hanging Roller Mill helps to make full use of gravity and improves grinding efficiency.
Advantage two: save energy. The design of hot air entry reduces the additional energy required in cement production and reduces production costs.
Advantage three: small footprint. Compared with traditional horizontal mills, the vertical design of the suspended mill reduces the floor space and is suitable for production plants with limited space.
Advantage four: Accurate powder separation. Through the precise operation of the separator, the particle size distribution required for cement production is ensured and product quality is improved.
Development Trend of Suspension Mill
In the future, the application of Hanging Roller Mills in cement production is expected to occupy a place among intelligent, automated green grinding equipment. Sensors and automatic control systems can be combined to achieve highly automated production. Improve the working efficiency of the Hanging Roller Mill and promote production capacity.
