Heavy supply vacuum extruder Fuyuan good quality stable production and practical use of clay brick products in order to solve the problem of waste of land resources, Henan 巩义富 source Heavy carefully decades of research, development and production of coal gangue latest vacuum brick, double stage vacuum brick clay brick goodbye to the use of history, began using shale, coal gangue, construction waste and other brick-making journey. I am in the digestion and absorption of foreign advanced technology, based on the combination of conditions, to develop a new generation of energy-saving compact brick-making equipment, two-stage vacuum brick structure and technology have greatly improved and breakthroughs, with the same model portfolio type or compact vacuum brick compared to 35% of investment savings, the device itself 30% reduction in power consumption, output can be increased by 20%, can be applied to fly ash, cinder, slag, coal gangue, shale and other materials, more compact, affordable, easy operation and maintenance. Old brick technical innovation need to update a host, without replacement power transformers and ancillary equipment installed on the original foundations 3-5 days to reach production of high-grade red brick and hollow brick production purposes.
