Molding Technology of Vacuum Brick Machine
Generally considering, the forming of vacuum brick machine is easily in, which has no technique for brick machine factory. But with the development of the reform of wall materials, brick factory produces a variety kinds of bricks, in addition to the common hole rate of 25% porous brick, and the hole rate of 30% - 50% hollow brick.
In recent years, the structure of high rate of holes is more complex for sintering block. The general trend of sintering block reflects in more complex shape, much higher requirements for performance and technology. And there is a big change in raw materials for brick factory. Many brick factories start to use materials like shale, coal gangue, fly ash and other poor formability as raw material to make bricks. Therefore, vacuum brick machine molding technology should be paid more attention by people in the brick and tile industry.
Now a lot of brick factories use shale, coal gangue, fly sah as raw material to make bricks, so the wear resistance requirement of mud cylinder liner is higher and higher. Some brick factories have adopted high chromium cast iron liner, and the wear resistance improved several times.So this kind of practice is worth promoting. its wear resistance and high chromium cast iron is also very similar. To ensure the good working condition of extruder, the choice of mud cylinder bushing materials is an important problem, it should be paid full attention.
