Factors to Consider When Choosing Perfect Crushers
Whether to use hammer crusher or construction waste crusher is up to the abrasiveness of the materials that need crushing. When the magnesian content in the limestone exceeds 4%, it shows that the limestone has very strong corrosive effect. The corrosivity of the loose stones will obviously become stronger as the sand quantity increases.
There lies no fixed relation between the abrasiveness and compressive strength of the materials, and there is no clear and direct relation between the quartz content and corrosivity. On the contrary, the particle size and distribution of the quartz of the limestone will have great effect on the abrasiveness. Lime stones with little abrasiveness consist of very tiny quartz particles that are scattered loosely which can be observed through the optical microscope. Instead, among those high abrasiveness lime stones, the quartz granule has the size of 0.1-0.05mm.
When choosing the ideal crushers for the machinery industry, we should consider the following factors:
1.To select perfect crushing machine means to perform a series of material performance testing. For example, when there exists too much fracture soil and hill-skin soil mixed in the lime stones, we should first consider using the construction waste crusher, namely the mobile impact plate type which can work as the wet clay crusher. When dealing with the high moisture coal bulks, we shall not apply the hammer crusher and its grid section will work as the superfine crusher.
2.For the same type of lime stones, different compressive strength and contents of SiO2gO will result in the application of construction waste crusher.
3.When manufacturers design the crushing equipment, they should not only consider the differences lying in the performance and structures of the same materials, but also think about the feed particle size and reduction ratio.
