Descriptions:

The vertical cement mill, also known as a vertical roller mill (VRM), is large-scale cement grinding machine. It sets crushing, drying, grinding, and grading transportation in one.

What Is a Vertical Cement Mill?

A vertical cement mill, also known as a vertical roller mill (VRM), is a large-scale grinding machine to grind the cement clinker. As a typical type of mill, the vertical cement mill sets crushing, drying, grinding, and grading transportation in one, and it grinds bulk, granular, or powdery materials into powdery material as required.

Unlike traditional cement ball mills, which operate horizontally, vertical cement mills are set up vertically. Vertical roller mill has the advantages of energy-efficient and stable quality. It is designed to achieve high grinding efficiency and reduce energy consumption.

What Is Vertical Cement Mill Used For?

CFTC vertical cement mill is used for various grinding applications in various industries, including clinker grinding and raw material preparation. Its efficient, integrated design makes it essential for modern, energy-efficient cement production.

What Are the Features of Vertical Cement Mill?

1. Adopt the sealing of jointing arc board, simple and reliable in structure with good sealing effect.

2. Resorting to the roller turning equipment can conveniently turn the roller out of the mill for overhauling.

3. Perform grinding, drying, and classifying in one integrated operation, reducing the complexity of the grinding process.

4. Compound separator improved powder selection efficiency. Has an automatic function of roller uplifting and down falling and can realize idling startup.

5. Mechanical limiting structure can avoid direct metal friction and collision between roller and millstone, increasing the use security.

6. The operation pressure is low in the hydraulic pressure system, decreasing the oil leaking failure and vibration of the mill, which is conducive to operation and management.

What Are the Parts of Vertical Cement Mill?

A vertical cement mill is a type of vertical roller mill. The structure of the vertical milling machine is mainly composed of the grinding roller, grinding table, separator, swinging arm, gearbox, stand, hydraulic system, and other parts. 

The main components of a vertical cement mill are grinding rollers, lining plate, and swinging arm. Roller bearing adopts the concentrated cycle lubricating of thin oil, guaranteeing the running of the bearing under the conditions of low temperature and pure grease and effectively prolonging the longevity of the bearing.

How Does Vertical Cement Mill Work?

The raw material falls to the center of the grinding disc through the feeding pipe. The rotating grinding disc uses the centrifugal force to evenly disperse the raw material outward to form a material bed of a certain thickness. In this process, the material is crushed and broken by multiple grinding rollers on the grinding disc.

Driven by the continuous centrifugal force, the material continues to move toward the outer edge of the grinding disc. The material leaving the grinding disc encounters the hot gas entering the mill through the air ring, and rises and enters the separator. In this process, the material exchanges heat with the hot gas, and the water is evaporated quickly. Powder concentrator controls the granularity of finished product at the exit of roller mill.
