It is inevitable that man-made or mechanical failure will cause production stoppage or idling in the process of brick production. The temperature of the empty kiln rises sharply because of the temporary idling, that makes a large area of technology defects occurred in the firing of the brick in the kiln. This compensator can be filled with bricks when large number of bricks producting,and discharge the stored bricks when the kiln is idling, so that the above production problem can be solved.
