Several Steps of Fire Clay Brick Production

Our company mainly produces fire clay brick, has advanced technology, strong technical force, complete detection equipment. Fire clay brick production has several steps:

1. Borrow earth. The soil bake brick uses taking from two feet deep of the ancient soil under the earth’s surface. The layer of soil color is slightly deeper than the overburden，it formed in eighty thousand to about eighty thousand years ago. At that time, the earth’s climate is warm and moist, rich biological role makes this period of the formative soil soft and sticky, is good material of fire brick.
2. Dig out of clay, in the process of passing about half a year of open air accumulation, let sunshine illuminate, snow and rain frozen erosion, make its internal decompose and loose, then by manual crushing, sieving, leaving only fine pure soil.
3. Add water into pour soil, make it moist, and then repeatedly refine, or use the cow power trample, make it become thick mud, human through mud and refine need five to  six times, the process plays a crucial role in the quality of the brick.
4. Fill soil into wooden blocking mode, after compaction, use iron wire to scrape off the excess sludge and become blank shape. Before blocking, need to sprinkle a layer of fine sand under wooden underground, in case of mud and ground adhesion.
5. After stripping the brick, need to place sun back to dry in the shade, to prevent exposure to make brick bad and appear crack and deformation.
6. After waiting for adobe completely dry (about one to two months), then into the kiln, the process is one of the most important link in the whole process of brick, common brick uses coal as fuel, while compactness higher feed slurry brick uses wheatgrass, pine slowly burn, etc.
