[0002] A brick blank, also known as a green body or raw brick, refers to an intermediate product formed by shaping clay into a specific shape, size, and strength using external force and a mold, and ready for firing. Undried brick blanks are called wet blanks, dried ones are called dry blanks, and bricks that can be used directly after forming without firing are called unfired bricks. In refractory material production, the quality technical indicators of brick blanks include their dimensions and shape, unit weight, density, porosity, and strength.

[0003] Existing brick blank dryers can dry brick blanks, but uneven heating often occurs during the drying process. In addition, the size of the trays for placing brick blanks in the dryer is fixed according to the size of the mold, which makes it inconvenient to adjust when drying brick blanks of different sizes.
