Latest company news about How to solve the problem of wind cracks in the drying process of bricks?
  1. Strengthen the weathering and humidification of raw materials. Various raw materials and internal fuels should be mixed evenly. Impurities in the raw materials should be removed in time to ensure uniform drying and shrinkage of the blanks.
  2. Timely repair the raw material preparation equipment to meet the process and technical requirements to ensure the quality of raw material crushing and mixing. Prevent uneven crushing, mixing, extrusion and other processes due to equipment problems, which may cause cracks in the blanks.
  3. Timely repair and replace the extruder auger to prevent cracks caused by excessive wear of the auger, unbalanced raw material extrusion speed, inconsistent blank density and inconsistent drying shrinkage.
  4. Keep the strip cutter flat, repair or replace the extruder mouth to prevent the mud strips from being bent when passing through the strip cutter due to unevenness, causing cracks in the blanks; prevent cracks caused by uneven water (oil) paths at the four corners of the extruder mouth. When water is discharged from the blank, a large capillary force will be generated, and its value can reach 70kg/m3. Only by providing a homogeneous and healthy green body can the occurrence of drying cracks be avoided.
