The specialized classifier for fly ash is a device used for processing fly ash, mainly used to classify the coarse and fine particles in fly ash for subsequent utilization and processing. Its main working principle is to use the separation effect of particles of different masses under different centrifugal forces to separate fly ash into different grades of specifications through an air flow separator. Graded fly ash can be used in different application scenarios, such as concrete admixtures, cement production, etc.

Working principle

The working principle of the specialized classifier for fly ash is based on the differences in centrifugal force and aerodynamic resistance of particles in the airflow. After being uniformly atomized by the air ash mixer, the fly ash is sent to the sorting machine through negative pressure. In the grading cylinder, fly ash particles are subjected to centrifugal force and aerodynamic resistance, and particles of different diameters will move along different trajectories to achieve grading. After separating coarse and fine particles, coarse particles can be further processed or recycled, while fine particles can be used in building materials such as concrete.

Application scenarios

The specialized classifier for fly ash is widely used in industries such as cement, electricity, and building materials. Its main function is to separate and screen fly ash that meets precision requirements through the action of airflow, and then produce fly ash bricks or other building materials. Graded fly ash can replace some cement, increase the fluidity and pumpability of concrete, reduce hydration heat and shrinkage cracks, especially suitable for large volume concrete and underground and hydraulic buildings.
