Introduction of square concrete spacer machine: This is an automatic cover block making machine production line. The whole line includes the host machine, conveyor belt, mixer, stacker. 1. Function This machine can produce various different hollow blocks, solid blocks, pavers and curbstones by changing its mould. 2. Mould The moulds adopt precise line cutting technology and carburizing treatment technology to assure longer mould life span and increase the block mould precision, so the brick moulds have better performance and longer service time. 3. Material The raw materials of the blocks can be cement, concrete, crushed stone, sand, Fly ash, dust, cinder and other industrial wastes. 4. Molding technology Hydraulic technology is adopted by this machine. And the pressure can reach up to 21MPa. So the blocks are strong and durable.
