The natural sand resources shortage, low quality, mechanism sand as the only industrial recycling of resources, play an important role in alternative, investment sand production equipment become in the production of building materials a striking new type of \"green project\". In the process of project construction, the need to be cautious about the market demand is not clear, the choice of the mine is not comprehensive, equipment procurement is not reasonable, the three major risks.
Risk One: market demand is not clear
Sand aggregate is a kind of basic construction raw materials, in the investment sand production equipment, to consider the national economic development, regional construction, investment and other macro level risk factors, forecast economic development trend, to understand the local construction projects and the subsequent project size, and then according to the engineering quantity calculation of aggregate size, mechanism sand quality acceptance and quality standards, and combined with the above factors, reasonable to make market positioning, and to continue the mine resource exploration, equipment selection and preparation. Once market demand for positioning is not clear, is not accurate, will cause the sand product unsalable, equipment capacity had left or saturated, mine resources waste and finished products manufactured sand quality unqualified, equipment use high cost serious risks.
Risk two: mine selection is not comprehensive
Mine resource selection is very important, but also the most easily overlooked, but also the most not comprehensive. Mine directly determines the type and composition of the rock you choose, and the source rock and the material source are closely related to the crushing efficiency, the quality of the finished product, the abrasion of the equipment and the utilization of the byproducts. Followed by the reserves of mines and mining difficulty, mines position is also very important, or because reserves enough, lead to mine soon broken mining or rock taste decline, to draw on the management experience of some foreign aggregate mines, long-term, orderly and sustainable mines use planning. For example, consider some green mine construction and mine green policies and regulations, especially in the air quality of the environment in high pressure areas to prepare for a rainy day, as early as consideration. Once again is the approval of the mine, the use, the EIA and other relevant policies and procedures to understand clearly, complete, to avoid due to non compliance with laws and regulations to stop the project, equipment and other risks.
Risk three: sand and gravel equipment process and type selection unreasonable Sand is the key equipment in the equipment selection, selection also faces multiple risks, first of all to avoid the market demand, mining selection risk lead to two types of equipment, process risk aggregate unreasonable, for example, can not adapt to the ore rock crushing equipment, equipment capacity is not enough, the expansion ability is limited; the third is to consider the development trend of sand production process and equipment, can not use backward or obsolete products, such as grinding mechanism of sand, water sand, roll crushing mechanism of sand is relatively backward as far as possible not to use, or will cause the risk of equipment rapidly eliminated; and sand production equipment should pay attention to the quality of the products, try to choose brand products, reduce the risk of the frequency and the probability of equipment failure. Is the so-called \"reasonable equipment, worry not from you\". In the investment sand production equipment, we must take full account of the above risks, and more understanding of the situation, a number of consulting industry experts or technical personnel, to achieve the scientific, rational and efficient sand production equipment.
