Cement separator

Cement Separator

A cement separator, also known as a cement pulverizer or cement cyclone separator, is a kind of equipment used to separate ground cement clinker and ground cement powder in a cement mill system.
Cement Mill Separator is usually installed at the end of the cement mill to receive the material from the mill and separate it from clinker and cement powder.

In terms of structure, the machine adopts inverted feeding and downward air intake, and integrates the plane eddy current classification, force sedimentation classification, and centrifugal sedimentation classification methods, so that the grouping efficiency of the machine is high, and the fineness can be easily adjusted within the range of 200~1000 mesh.
The system configuration is improved, and the energy-saving effect is remarkable.
The products are suitable for production units of ultrafine powder processing such as cement, desulfurization calcium-based powder, kaolin, titanium dioxide, slag powder, ultrafine coal powder, and fly ash separation production units.

Product Description

The cement powder separator is the latest technological product developed on the basis of the most advanced international powder separation principle and by using the aviation aerodynamic analysis method.
This product breaks through the two-separation theory of “coarse and fine powder” in the conventional closed-circuit grinding system, and “divides the material into three”, that is, coarse powder, medium coarse powder, and fine powder. Significantly increase mill output.
Its internal structure is reasonable, and the powder selection effect is remarkable.
It is the first choice product to improve the quality of the grinding system after the implementation of the new cement standard and guides the new trend of powder separator technology innovation.

Cement Mill Separator is a cyclone separator that separates fine powder and coarse particles in cement clinker through centrifugal force and gravity.
It is usually installed at the end of the cement mill to receive the material from the mill and separate it from clinker and cement powder.

The working principle of Cement mill separators can be divided into two aspects, rotation separation, and gravity separation.

Spin Separation

In the process of rotary separation, due to the different gravity of cement particles with different particle sizes, the cement particles with larger particle sizes will be affected by gravity when they move down along the wall of the cylinder in the cylinder, so the heavier particles will be separated during separation.
The bottom of the container is collected and returned to the cement mill through the pipeline for re-grinding.
The fine particles are carried by the airflow to the top of the separator and transported through the pipeline to the next process link, such as a cement storage tank or packaging workshop.

Gravity Separation

The interior of the cement mill separator usually includes a conical cylinder, which is equipped with a set of rotating impellers.
When the cement clinker enters the separator from the cement mill, it will be forced to form in the cylinder through the action of the impellers. swirling airflow.
Due to the small movement resistance of the fine particles, the fine particles are sucked up by the airflow and become the airflow in the center of the cyclone, forming a separation layer in the cyclone, while the heavier bulk materials move down along the wall of the separator cylinder.

Cement Mill Separator Working Principle

In general, Cement Mill Separator realizes the separation of fine particles and coarse particles in cement clinker through the functions of cyclone separation and gravity separation and improves the production efficiency and product quality of cement mills. It is one of the indispensable key pieces of equipment in the cement production line.

Separator in cement mill Structure

The structure of the cement separator is compact and the manufacturing process is relatively complicated.
It is necessary to accurately calculate and design the material, size, and spacing of its various components.
An excellent cement separator needs to have the characteristics of high-efficiency separation, stable operation, and low energy consumption to meet the requirements of the cement production process.

The rotary separator is the core component of the Cement separator, usually in the shape of a cylinder with a certain number of rotating blades inside.
When the high-speed gas flow passes through the rotary separator, the centrifugal force separates the particles from the gas flow, the particles fall into the bottom of the separator, and the gas is discharged from the top.

The guide vane is located on the upper part of the rotary separator, and its function is to control the direction and speed of the airflow so that the airflow has a suitable rotation speed and centrifugal force when passing through the rotary separator.

The air guide plate is located at the lower part of the separator, and its function is to separate the separated particles from the unseparated particles, so as to achieve precise control of the particles.

The drive system is mainly composed of motors, reducers, and transmission shafts, and realizes its rotational motion by driving the rotary separator.

The connection parts include the air inlet, air outlet, inlet bucket and outlet bucket, and other parts, which are used to connect the Cement separator with the cement mill system and other equipment.

cement classifier function

  1. Separation of particulate matter and gas: A cement mill separator separates particulate matter in high-speed airflow through rotating separators and other components, thereby controlling the particle size distribution in the cement mill and making the grinding effect better in the cement production process.
  2. Particle size control: A cement mill separator can precisely control the particles in the cement mill, so as to realize the control of the particle size distribution in the cement mill so that the particles produced by the cement mill meet the required particle size requirements.
  3. Energy consumption control: A cement mill separator can control the energy consumption in the cement production process and reduce the production cost through the control of gas flow rate, separator speed, and other parameters.
  4. Stability: The cement mill separator has stable operation performance, which can ensure the accurate separation and fine control of particles in the cement production process, and ensure the stability and continuity of the cement production process.

cement mill classifier use

The main function of the cement classifier is to separate the fine powders in the cement clinker so that these powders will not re-enter the cement mill, thereby affecting the efficiency and operation of the mill.
At the same time, it can separate the coarse powder and bulk materials in the cement clinker, so that these materials can be returned to the mill for re-grinding.

The design of the cement classifier adopts the cyclone separation technology, that is, the material is introduced into the rotating conical cylinder, and the material is divided into components with different particle sizes through the centrifugal force and gravity in the cylinder.
The lighter fine powder will be sucked into the air stream, enter the top of the separator, and be piped to the storage tank or loading room.
While the heavier lumpy material will be thrown to the bottom of the separator and returned to the mill through another pipeline for re-grinding.

Cement classifier plays a vital role in cement production, it can improve the production efficiency and product quality of cement mills, and reduce production costs.
Therefore, it is widely used in all aspects of the cement production line.

Cement Mill Separators Application

cement mill separator efficiency calculation

First of all, it is necessary to determine the output quality of the separator, that is, the output of the clinker and fineness adjustment material.

It is necessary to measure the feed quality of the cement grinding head.

Measure the separator feed quality, this includes the total amount of clinker and fineness adjustment material entering the separator.

Separator efficiency can be calculated by the following formula: Efficiency = (Output Mass/ Input Mass) * 100%

Wherein, output quality and input quality refer to the output and input quality of clinker and fineness adjustment material respectively.

Finally, it is necessary to analyze and evaluate the calculation results of the efficiency of the separator to determine whether the separation effect of the separator meets the expected requirements.
If the separation efficiency is lower than expected, it is necessary to find out the reason and take measures to improve the performance of the separator.

Cyclone Separator in Cement Industry

Cyclone Separator (cyclone separator) is a common separator equipment in the cement industry.
It separates particles and gases by using the rotational force and centrifugal force of the gas and is one of the important dust collection equipment in the cement production process.

The following is a detailed introduction to Cyclone Separator in the cement industry:

Cyclone Separator guides airflow in a conical device, causing the airflow to generate centrifugal force during rotation.
Centrifugal force separates the particles and collects them at the bottom of the unit.
Clean air is exhausted from the top of the unit.

Cyclone Separator is mainly used for dust separation and collection in the cement industry.
It can be used to collect the dust generated in the cement mill and reduce the emission of dust, thereby improving the working environment and reducing the environmental pollution.
