River pebbles crushed for sand making is one good investment project, but the problem is that this kind of materials cannot be easily crushed like the other mineral ores. The hardness of river pebbles is very tough, which is one excellent raw material for the building construction, and whose hardness can catch up with that of the granite, so that is the reason why it has the higher requirement for the crushing process, and there are only several manufacturers who have the power to produce this kind of mining equipment.
This kind of sand making production line should be considered carefully, and our experts introduce the jaw crusher for the coarse crushing process and the cone crusher for the secondary crushing process, and the following equipment will be the circular vibrating screen, and the last certainly will choose the vertical shaft impact crusher. The reasons why our company chooses this combination and integration of the machine mentioned above on can be explained in the following: choosing jaw crusher for the coarse crushing is because of the lower cost, and choosing cone crusher for the secondary crushing is because of its bigger crushing ratio, higher working efficiency, lower consumption and its laminated crushing principles, and the vibrating screen has the better performance characteristics, simple structure and the competitive price, and the reason why choosing VSI sand making machine is that the granularity of the finished products made by this machine can be closer to the size of the natural sand while its working efficiency is higher at the same time.
The configuration of sand making production line not only can be accepted in theory, but also can be realized in the practical operation. There is one of our customers whose production line chooses the following configuration: GZD-960×3800 vibrating feeder +PE-600×900 jaw crusher +YZS-1860 circular vibrating screen +CSB-1321 cone crusher +VSI-1140 sand making machine +XSD-3016 sand washing machine.
