Introduction to Fiber Natural Grading of Brick Machine Fiber Tray

It is completed simultaneously during the paving process. This method mainly utilizes the different electrical quantities of coarse and fine fibers themselves, and then uses mechanical or wind pressure to classify the centrifugal force or buoyancy generated by fibers of different weights. Therefore, the use of different paving heads results in different functions of natural grading, which can be divided into three categories:

① Natural grading of mechanical paving: Using the reset difference between coarse and fine fibers for grading, the heavier coarse fibers on the brick machine fiber support plate are thrown far away by centrifugal force, while the lighter fine fibers fall nearby by centrifugal force.

② The natural grading of airflow paving: fine fibers are lightweight and have high buoyancy, and can be blown farther by air masses. Heavy coarse fibers have lower buoyancy and can be thrown closer and fall.

③ Mechanical air flow mixed pavement natural grading: Due to the overly strong grading of the first two types, it is not conducive to the product structure. Therefore, by utilizing the two opposing grading principles, an appropriate synthesis can be made to adjust the ratio of coarse and fine fibers.

In short, this grading is naturally formed during the molding process. The fiber support plate of the brick machine creates a gradual transition structure from coarse to fine from the middle layer to the surface layer of the slab. Its advantages are the elimination of specialized sorting equipment, simplified process flow, and reduced power consumption, but the product cannot freely control the thickness and ratio of the surface and core layer fibers as in pre sorting.
