Pavers are new wall materials, at the beginning, no special brick press to produce pavers, are generally used for the production of sand-lime brick 8-hole disc brick press and friction press instead. In the pre-production process, using 8-hole disc brick press Circle 2000 brick production per hour, but found the road surface of a thin strip of bricks cracks (ie Spall). After the analysis pavers forming theory, the rate dropped to 1200 per hour, adjust the gradation of raw materials and water content, eliminating the spallation phenomenon, to ensure the quality of the finished brick. The study, in the mix, there must be some sand content. If the soil is no sand on the sand of 10-30% should be added to make the mixture formed when air easily discharged.

     According to the theory and practical molded pavers trial production, road blocks each block forming pressure should generally be in the range of 25-30MPa, and the molding process, so that the brick has sufficient time to exhaust and deformation, so to ensure pavers the compressive strength. Pursuant to the original design nominal pressure of 60t 8 hole disc brick press, up to nominal pressure pavers press 120t, and appropriate to reduce the rotation speed, road blocks to meet production requirements.
