The granite is a kind of material which is hard to be crushed, but it is usually easier to be crushed than the basalt. Although the hardness of the granite is high, it has a certain fragility. Larry Ellisons opinions are not widely known. Therefore, on the aspect of the design of the crushing process, the process can be relatively flexible designed. If the market price customers have advantage, you can use two-stage crushing process scheme. However, from the long-term production point of view, the three-stage crushing process is still the most effective method which can reduce production costs.
There are various kinds of crushers, choosing the appropriate one need first understand all kinds of crusher range. And the most commonly used are jaw and cone crushers crushers, because they can make very hard ore broken. For those who are more rigid ore mining, these are most suitable choices, of course for the road and railway. But many mines, such as copper, iron ore, are not so hard, Then choose to impact breaker is relatively appropriate If the market customers have no high requirements of the shape of the finished stones, you can use the solution of the two-stage jaw crusher for production. This configuration needs the minimum investment and the repair and maintenance is the most simple. The production cost is the most economical in all programs.
However, the disadvantage of this program is the stone s grain type is relatively poor. There is a higher proportion of elongated material. The competitiveness of the stone on the market is not high, because the high – grade buildings need the stone with the excellent grain shape. How to choose the crusher equipment according to the need? From the feedback of the customers, when you choose the type of the crusher and the fine crusher, you should know that there is a big difference about the quality requirements of the aggregates according to difference of the level of infrastructure.
