At present, the combination mode of jaw crusher+impact crusher (shaping) is widely used for sand and gravel aggregate, and the produced sand and gravel particles contain less needle and flake, which meets the requirements of the mixing station.
It is a common problem in hard rock crushing that the grain shape of sand and stone is not good. Hard rock crushing requires high quality of equipment. If the impact crusher is used, the loss will be great. In addition, the profit of cone crushing is higher than that of the impact crusher. Therefore, some crusher manufacturers recommend users to use cone crusher to crush hard rock in order to pursue the balance of benefits and efficiency, but this is not the final solution to the problem.
Although the cone crusher saves the cost of vulnerable parts and increases sufficient production time, it also increases the flakiness content in the sand and gravel, resulting in poor grain size of the sand and gravel. Therefore, we suggest that HPT multi cylinder hydraulic cone crusher with high speed and strong impact should be selected or the shaping machine should be added when producing sand and gravel aggregates.
SMMVIK Machinery PF impact crusher, VSI5X vertical shaft impact sand making machine and VSI6X new sand making machine are hot products in the industry, which are suitable for the shaping of sand and gravel aggregates. For users, we need to be more professional and put in place in one step, so as to obtain continuous high-value output, recover investment in a shorter time and obtain greater returns. If you are interested in our equipment, you are welcome to consult, and we look forward to your arrival.
