1. 1. Mixing: After strict inspection by the quality inspection department, the raw materials of clay clinker and other additives are uniformly mixed by Kerui fully automatic batching machine and mixing system.
   2. Forming: With 20 units of 60 ton press machines, we efficiently and precisely produce the clay bricks you need.
   3. Drying: The refractory fire clay bricks automatically enter the drying kiln to evaporate excess moisture, preventing subsequent cracking and deformation.
   4. Sintering: Kerui Refractory has introduced two 168-meter-long high-temperature tunnel kilns, where the internal substances of the clay bricks undergo transformation to form a strong structure.
   5. Cooling: The clay bricks release internal stress through natural cooling.
   6. Packing: After passing secondary quality inspection, the finished clay bricks are packed. Kerui uses high-quality plastic film, steel bands, and sterilized pallets for strict packaging to ensure safe delivery to customers.
   7. Shipping: Kerui shipping department collaborates with internationally renowned logistics companies to provide customers with the most cost-effective shipping solutions. We fulfill delivery according to the contract.
