Why do Clay Bricks Crack?

The majority of people who own brick factories put in a lot of time and effort to start them, but not all of them succeed. This is because before starting their clay brick factories, they didn't do enough research and service. In order to prevent investment losses in the production of Clay Bricks, we have compiled the following summary of the frequent occurrence of low-quality bricks and the frequent mistakes made by new factory owners.

1. Adobe is deformed and appears to have large cracks. In more dire circumstances, Adobe will separate as a whole.

Reasons: The pug has almost no plasticity and a low plasticity index.

Solution: to raise the plasticity index of the raw materials, like clay, coal slime, and clay agent, among other things.

Raw materials with a low plasticity index can also be improved by aging, watering, stirring, rolling, extruding, and other processes.

2. There are no horns or flutes, and the body of the adobe is uneven, with obvious particles and additional sand pits.

Reasons: The raw material shatter does not meet the requirements for making bricks due to the abundance of large particles.

Solutions: When necessary, acquire equipment for fine grinding to reduce the raw materials to particles no larger than three millimeters.

For raw material pretreatment, roller crushers and double shaft mixers are two pieces of equipment that are out of reach for some kiln owners' budgets. There are a few kilns that only have two rollers, some that only have mixers, and still others that have neither. How can we make high-quality bricks if the mud raw materials contain bricks, tile, stone, and other debris? despite the difficulty of sending someone to clean them up. Utilizing auxiliary equipment is a fundamental strategy for resolving the issue.

3. Adobe's nature is unstable, at times excellent, and at other times poor.

Reasons: uneven mixing of raw materials 

Solutions: Boost the mixer and feeder 

Some brick factories don't have rollers or mixers, and even if they do, a shovel is used to feed the brick machine artificially. Two major drawbacks arise from this: First, there isn't enough soil between the raw materials. This is demonstrated by the inability to evenly stir the inside fuels, such as coal, coal gangue, slime, and others, in the Yellow River sludge. The plasticity of raw soil is not exactly the same. The two different approaches will unavoidably cause Adobe's quality to become unstable.

4. as soon as the adobe and malformed mud column are cut, they will spread.

Reasons: Answers for the vacuum chamber's disappointment: a, enhance the technology for maintaining, servicing, and repairing brick machines to ensure the machine's properties continue to function normally. b, carry out the necessary technical transformation 

Solutions: Another factor that contributed to the vacuum chamber's failure is the sand-based raw material; The vacuum failure and the adobe's inability to mold are a result of the upper auger's closed mud layer being too thin and easy to pass through. The best approach to this problem is to alter the raw material ratio in order to raise the raw material's plasticity index. Alternatively, you can reduce the superior auger's front end by 2-10 centimeters, depending on the soil's material properties (do not attempt this on your own; You need to collaborate with technical experts).

5. Numerous Wall Bricks cracks on the two sections of the adobe that split, additional wastes after sintering 

Reason: Because raw materials contain an excessive number of viscous ingredients, their plasticity index is too high.

Solutions: alter the raw material ratio and reduce the plasticity index. Clay can be used to thin coal ash, slag, fly ash, or brick powder waste because it has a plasticity index of up to 25.

6. Adobe that is flexible and does not fracture when cut.

Reason: inadequate moisture control in the mud.

Solution: Sludge's excessive water content is demonstrated by adobe that is soft and simple to deform. If the mud section breaks or splits quickly after embellishment, which is caused by too little water in the mud, it could possibly be fixed by adding more water.

7. Block creation limit is unsteady

Reason: Not outfitted with a container feeder to set aside cash 

Solution: Some block manufacturing plant proprietors don't utilize box feeders and on second thought feed the dirt physically. As a consequence of this, the amount of soil fed varies; at times, it is greater than what the extruder requires, while at other times, it is less than what the extruder requires. This has a significant effect on the capacity for production.
