Since reforming and opening,rapid growth has accelerated the construction of socialism with Chinese characteristics. There was a great consumption of construction building products in the town planning and construction, one of which is cement. Cement production can hardly do without the participation of crushing machine , it was widely used in cement industry, and has played a decisive role in the comprehensive utilization of mine resources.
Crushing, solid material was shattered to small pieces, while grinding is to have coarse particles became powder. You can check different particle size after crushing as below:
Crushing | primary crushing | Diameter below 300mm |
Crushing | middle crushing | Diameter below 80mm |
Crushing | fine crushing | Diameter below 8mm |
Grinding | ordinary grinding | Diameter below 0.08mm |
Grinding | fine grinding | Diameter below 0.05mm |
Grinding | superfine grinding | Diameter below 0.01mm |
Let us take cement production as an example, raw material limestone diameter range from 300-500mm to 1000-2000mm when it was being mined. Every production of 1 ton cement, about 3-4 tons materials need to be crushed,electricity consumption during this crushing process is about 60%-70% of the whole plant.Therefore, a reasonable choice of the crushing machinery ,, can help to simplified crushing process, to improve the traditional grinding operations,and get the goal of high quality, low consumption security to a cement industry.
Suzhou (Zhangjiagang) YaoYu Wear Resistant Company developed high hardness chromium carbide overlay plate for crushing machine, components of of crusher is welded high chromium alloy abrasion resistant plate, the hardness can reach up to HRC58-62 or more, also have enough impact toughness.
