Description
Technical field
The utility model relates to ore sizing technical field, especially relates to a kind of ore reduction screening blending system.
Background technology
Although Mineral Resources in China total amount is enriched, of a great variety, belong to third place in the world mining powers, occupancy volume per person is only world occupancy volume per person's 58%, is in the 53rd.Along with China's sustain economic, develop rapidly, process of industrialization is accelerated, and to the absolute magnitude of mineral resources demand in continuous increase, the imbalance between supply and demand of mineral resources manifested in recent years.China's economic in decades from now on, period that social development is the fastest to mineral resources demand growth, estimate that Mineral Resources in China demand will peak in mid-term in this century, have some important mineral products will sink into critical shortage situation.In the past in 10 years, output and the consumption of Chinese mineral products all maintain positive growth, and pig iron consumption figure increases by 8.1% every year, and steel consumption figure increases by 9% every year, and aluminium consumption figure increases by 11.6% every year.China establishes mineral trade relation with more than 100 countries, and mineral products import increases by 11.7% every year, within 2002, reaches 58,700,000,000 dollars.The first half of the year in 2003, Chinese imported Fe ore increases by 45% on year-on-year basis, and import copper increases by 40% on year-on-year basis, accounts for 20% of import market, world share, and the demand of China and supply directly affect Global Mining Industry and produce.The solid demand of China to mineral resources, has driven the development of World Mining Industry.Chinese Enterprises holds economic globalization opportunity simultaneously, implements global stratege o f resources, goes abroad, set up Strategic Mineral Resources deposit and security provisions system.What World Mining Industry was produced becomes increasingly prosperous, and adds the demand to mining equiment.
Ore, after being broken, often will utilize the working face of porous that mixtures different for granular size is carried out graded operation by its granular size, Here it is screening operation.
