Semi automatic small production line solid clay brick making machinery

Nowadays, the technology of sintered brick enterprises is also becoming mature with the improvement of the level of kiln construction technology, but there is still a common phenomenon in some enterprises that the damage rate is relatively high. In order to further improve the quality of sintered bricks and reduce the damage rate of finished products, we need to start from the following aspects:

1. Raw material selection and matching
The selection of raw materials is basically determined when the kiln is built and the site is selected, so it is a bit impractical to discuss the selection of raw materials after production. If the determined raw materials have low plasticity or too high drying sensitivity coefficient, it is easy to cause more fractures in the finished bricks. At this time, it can only be achieved through the matching of particles, the outsourcing and aging of raw materials, and the pressure of extrusion molding. Make adjustments.

2. Blending of internal combustion
The blending of internal combustion must be accurate and stable. The demand for internal combustion varies depending on the performance of the kiln, the climate, the moisture content and other factors. Therefore, there is no absolute uniform standard in the production process. The trial blending trial firing should be carried out according to the actual situation, and the trial blending should be accurate. According to the record of the fired temperature and the fire color of the finished brick, an accurate blending standard is determined and strictly implemented. If the internal combustion is too low, it will cause a large amount of external combustion input and even produce unqualified products. If the internal combustion is too high, it is easy to cause excessive roasting fire and increase the damage of finished bricks.

3. Moisture control and mechanical damage in production
The requirements in production are also quite strict, and the moisture content is the most important link. If the water content is too high, the hardness of the brick will decrease, and the general tunnel kiln is about 14-18 layers. If the brick hardness does not meet the requirements, it will cause the bottom brick to break and deform, and in severe cases, it may even lead to inverted bricks and affect normal firing. In the production, if the water content is improper or the water content is unevenly mixed, uneven mixing, etc. will cause poor healing of the bricks and bring difficulties to the drying and roasting.

4. Brick drying
Drying is the most difficult part to master. If the moisture content is too high, a large amount of vaporized water is easily produced during drying. If the temperature is too rapid in the initial stage of drying, it will cause cracks when the vaporized water passes through the surface of the body. In severe cases, the bricks will break. . Excessive moisture content can also easily cause the bricks to regain moisture and soften under the influence of the climate environment, which brings great difficulties to the baking work.

5. Cooling of finished bricks
During the firing process of bricks, the temperature in the kiln will generally rise to above 1000 degrees Celsius, and the body will become a solid solution. If it is suddenly cold, it will cause the body to solidify and shrink too quickly and cause fracture. Therefore, a reasonable heat preservation time must be determined according to the change of outdoor temperature, and the heat preservation length is sufficient to effectively control the occurrence of cooling fracture.

6, the code billet force
After the bricks are formed, depending on the hardness and plasticity of the raw materials, the bearing capacity is also the same. If the pressure is too large or the force is uneven, it will cause crushing. This phenomenon generally occurs within six hours after the completion of the bricks. It is already broken when incorporated into the dry. Therefore, it is necessary to ensure that the surface of the kiln car is flat, the stack must be straight and stable, the contact points are in good contact, and the billet is not inclined. Raw materials with too low plasticity can even consider choosing an appropriate amount of additives.
There are many other reasons that cause high damage. According to actual analysis and proper adjustment in all aspects, the problem of high damage rate of sintered bricks can be solved.
