Of course, it is to replace the crushing equipment that is not conducive to particle shape optimization with the crushing equipment that is conducive to particle shape optimization, or to add a molding link. For example, the granite gravel sand production line of Wally Sand Maker adopts PYF cone crushing and medium-fine crushing of impact sand making. Even if PYF series cone crusher is full of ore, it can't guarantee good particle shape, so impact sand making machine is used for further sand making and molding. Not only the one-time sand forming rate is high, but also the sand mold is beautiful. This is just a simple example, which shows that the problem of stone particle shape can be completely overcome, and it is not a intractable disease.
