Multi-cylinder hydraulic cone crusher adopts lamination crushing principle and can realize selective crushing to some degree and satisfy the technical requirement of “more crushing and less grinding”, so that it has very application in many industries such as mine, coal, metallurgy and chemistry. In its design process, there are many problems needing attention, which will be analyzed here by experts of Henan Hongxing Mining Machinery Co., Ltd.
As for single-cylinder cone crusher, to produce small-sized products, the discharging mouth should also be small, which will greatly reduce the output to and cause blockage to the crusher equipment, especially tertiary crusher. The means of solving this problem is to increase the discharging mouth, lengthen the pendulum stroke and improve the rotating speed of the movable cone. As for a tertiary crusher, it is advisable to lengthen the pendulum stroke when the compaction is not excessive but the degree of density is still sufficient. The longer that the pendulum stroke of the movable cone is and the higher the compaction degree is, the larger the discharging mouth will be, which can not only increase the output of the crusher, but increase the content of fine particles in the final products.
To sum up, when compressing the materials inside the crushing chamber of cone crusher, there should be sufficient compaction and high compression ratio to gain high output and significantly increase the content of final particles. To ensure high compression ratio, there should be reasonable cavity shape and reasonable structural parameters and motion parameters matched with the cavity shape, and there should be sufficient ores inside the chamber. Adopting high pendulum frequency and big pendulum stroke can make the movable cone go back to the final point and scatter the materials it meets in the returning process, thus carrying out lamination crushing. This idea has been realized in HP series crusher machine.
Seen form the complicated structure of cone crusher, single-cylinder hydraulic cone crusher has the simplest structure and the lightest weight and multi-cylinder hydraulic cone crusher, especially HP series multi-cylinder hydraulic cone crusher has the most complicated structure, for this reason, we should pay more attention to the design issue of multi-cylinder hydraulic cone crusher.
