Bricmaker automatic brick making plant could produce bricks from raw materials like clay, waster soil, river silt, shale, construction wastes, tailings, fly ash, gangue, life sludge, loess, etc.
Comprehensive raw materials analysis is the basis of brick making production process design, equipment selection, kiln structure, firing features design, fired bricks quality, and other factors of the brick plants. Raw materials analysis includes chemical composition analysis and physical performance analysis.
Loss on ignition: Caused by organics in raw materials. If higher loss on ignition, more hole rate on the products.
Chemical composition of brick's raw materials:
|Item||Suitable content %||Available content %|
|Loss on ignition||/||3-15|
|Calcareous content <0.5mm||0-25||/|
|Calcareous content 2-0.5mm||/||0-2|
Usually measure particles composition, plasticity, shrinkage, drying sensitivity and sinter ability.
|Particle category||Particle diameter||Reasonable composition|
Plasticity: When plasticity index in 7 ~ 15, most suitable for middle plastic mud extrusion.
Relationship of forming moisture content and drying sensitivity:
|Green brick molding moisture||20||26|
|Critical water of green bricks||14||10|
|Drying sensitivity coefficient||0.76||1.10|
