1. Machine's introduce The structure of clay brick machine is reasonably designed with high extrusion pressure. Compact structure and obvious energy-saving effect. It is suitable for producing various specifications of hollow bricks from shale, high-doped fly ash, clay and other raw materials. The machine has strong practicality, small investment, and is the ideal equipment for technical transformation of brick factory. The whole machine is steel structure, the reducer part is hard gear. The reamer adopts wear-resistant material spray welding process, which is convenient for maintenance and durable.
