Mining refers to the use of artificial or mechanical resources of the value of the use of natural mineral resources. According to the requirements of the different and technical and economic rationality of the buried depth of the ore deposit, mining is divided into two ways of open pit mining and underground mining. Mining, the most critical is the ore crushing, processing of refined ore for metallurgy, construction, chemical and other industries. Economic crisis, expanding domestic demand, infrastructure construction, making the use of sand stone, in addition, the national policy on the construction of the requirements to improve, artificial sand stone can be changed at any time to change the size of the finished product, to a certain extent, can meet the requirements, therefore, gravel investment opportunities. Diversified investment refers to investors (enterprises) in different areas, different industries (industry) to carry out investment business, or in the same industry to invest in the production of different products, to expand the scope of business, to carry out diversified business. Diversified business investment is the only way to increase revenue opportunities, and also a trend of modern enterprise management. quarry crusher is currently mainly exported to Southeast Asia, Africa and the Pacific and other regions. China is a big country in the production of quarry crusher, because the products of our country have some advantages, it is necessary to break into the international market. The next few years, we believe that our products exported to Southeast Asia and Africa more opportunities: first, relatively fast economic development in Southeast Asia and Africa, increase the investment on transportation infrastructure, mineral resources exploitation strength increase, especially in Africa, the quarry crusher demand increases; secondly, Southeast Asia and Africa, and other countries of quarry crusher development has lagged behind, the need to import; our products have a price advantage to greater into the scope of a range of options with Asian and African countries. At present, China's high-end products and supporting the export of products are mainly rely on imports, domestic development is relatively weak, so the enterprise in the basic technology and basic components of investment opportunities is relatively large.
