In 1989 the powder processing construction waste crusher and coal ash emissions up to 29500000 T, utilization rate of 15%. In the construction waste crusher process research and development, focus on building materials products, such as over the years invested considerable strength, is committed to the comprehensive utilization of coal ash and construction waste crusher aerated concrete development research powder, have a higher level in the material, process and mechanical equipment facilities, the annual use of ash is about 1000000 t.
Research on sintering and expanding type construction waste crusher ceramsite area is also very distinctive and depth.Through industrial pilot production obtained ceramisite, cylinder compressive strength is 1.512316; 2.0MPa, water absorption rate of 7% ~ 10%.
Because of Poland's lack of bauxite ore, so much attention is paid on the extracting aluminum oxide from construction waste crusher sintering of Professor Grazsu J, Krakow Institute of mining and metallurgy decomposition method has been applied for patent in 1966 built adult experimental factory produces alumina 5000T, also can produce 60000 t cement.
For the research of construction waste crusher building materials and natural radioactive elements in the problem, like Europe of the Federal Republic of Germany, Norway, Sweden did in twentieth Century 70's have a clear conclusion, have provided the content of radioactive elements limit, and also some phosphogypsum, construction waste crusher and other common building materials can to meet the requirements. birder2525 mary / Mining & Crushing Equipment |
