The research results of shale crusher

From crushing principle, crushing material is mainly divided into extrusion and collision crushing.From theory and in practice, the extrusion crushing include jaw crusher, cone crusher, not easy to cause excessive grinding, less powder crushing. Collision type crushing, like impact crusher, hammer crusher, vertical shaft impact crusher, crushing ratio is relatively high, the product has good grain type, but easy to produce powder. Based on the above principle, in order to further expand the sand making process of marble, shale, improve the quality of the finished product of aggregate, in particular with the change of grading, dust content and other standards, to improve the yield.

 

                                                                                                    

 

The actual use proved cone crusher produce gravel material,its fineness modulus, dust content, particle size distribution change at different discharge gates, inferred cone crusher can be used as secondary crushing equipment.

 

Under different discharge port and speed, impact crusher produce gravel sand with changed fineness modulus, dust content,particle grading, based on the results of the use as the feasibility of secondary crushing.

 

The whole process proved different speed and feed conditions, the final products has different fineness modulus and dust content. So for marble, regardless of the use of any form of crushing, it is difficult to change the original nature of the sand.It mainly decided due to the performance of its own.
