Ceramic tile roller kiln common problems and solutions:

1. The temperature control is unstable: Check the temperature sensor, controller, and the connection line to ensure that the connection is stable and the sensor is not damaged. Adjust the controller parameters to ensure that they work within a reasonable and accurate range.

2. Poor ventilation in the kiln: check whether the kiln door and vent are blocked, and whether the fan and air valve are working normally. Clean up the debris of the kiln door and vent, such as the failure of the air valve and fan, which should be replaced in time.

3. Improper kiln pressure of the firing belt: check the firing of products in the kiln, adjust the opening of the air valve according to the actual situation, and adjust the length of the roller kiln or replace the length of the firing belt if necessary. At the same time, check the kiln pressure regularly to ensure that the pressure at all points in the kiln is uniform.

4. Insufficient cooling belt: Check whether the equipment of the cooling belt works normally, such as fans, water pipes, etc. In case of failure, the equipment should be repaired or replaced in time. In addition, clean the water pipe of the cooling belt regularly to prevent blockage.

5. Product defects: Check whether the formula of raw materials and production process are correct. Adjust the formula or production process to ensure that the raw materials are fully mixed, extrusion, sintering and other processes are fully carried out to avoid cracks, deformation and other defects in the products.

6. Product frosting: Ceramic tile glaze frosting is mainly because the brick body expands slightly after moisture absorption, destroying the glaze and white frost. In order to prevent the occurrence of this phenomenon, the glazes with wear resistance, low bending strength and high porosity are used as far as possible. Reasonable adjustment of mineral composition of brick and glaze to improve its permeability resistance; Try not to use zirconium silicate as a glaze component to reduce the chance of crystallization; Control the firing temperature and time to avoid crystallization of the glaze; Improve the oxidizing atmosphere in the firing atmosphere.

The above are only some common ceramic tile roller kiln problems and solutions, and specific problems need to be analyzed and processed according to the actual situation. When handling problems, be sure to pay attention to safety and follow the operating procedures.
