The importance of innovation in brick machine industry
A senior manager of an equipment factory once called out loudly: the ancient sintered bricks and tiles have endured wind and rain for hundreds of thousands of years, but now the bricks that people burn can last for decades?
A boss of a sintered brick enterprise once kept asking why the output of a modern large section production line built with so much money is not as good as that of a simple small section tunnel kiln.
A leader saw the beautiful sintered blocks abroad and asked: when can we produce such products?
These problems are worth pondering by every practitioner: sintered bricks are not simple. What we have done is too rough. If we really want to produce sintered blocks according to European and American standards, there is still a lot of work to be done from process to equipment.
In the past decade, the mechanical equipment in the industry has developed greatly, and the degree of automation has been greatly improved, but there are still areas that need to be improved. Simply copying foreign technologies based on different national conditions and raw materials cannot solve domestic problems. There are not enough high-quality minerals in China to burn bricks. Instead, we need to digest industrial waste, construction waste and urban sludge. We need to develop machinery and equipment suitable for such raw materials.
Most of the foreign fired bricks are fired by external combustion, which is not in line with China’s national conditions. At present, we mainly use internal combustion bricks. Even if we popularize sintered blocks in a large area in the future, it is unlikely to completely use external combustion bricks. Therefore, we need to make more efforts in combustion and hydrodynamics to overcome the differences between internal and external combustion bricks, not only to reduce production costs, but also to ensure product quality.
