Cone crusher has become the first choice for crushing high-hardness cobblestones due to its unique laminated crushing mechanism. This mechanism can effectively cope with the high hardness of cobblestones and achieve a more ideal crushing effect. The cone crusher is superior in the design of wear-resistant parts, which not only improves the crushing efficiency, but also significantly extends the service life and reduces maintenance costs. When processing hard materials such as pebbles, the cone crusher shows higher applicability performance and economic benefits.

The cone crusher is used to process cobblestones. Its large-diameter main shaft, reinforced main frame design, and independent thin oil lubrication automatic control system not only improve the robustness and operational stability of the equipment, but also perfectly meet the crushing needs. The independent lubrication system realizes multi-point precise control, double guarantees bearing lubrication, and integrates automatic safety protection mechanisms to significantly reduce maintenance costs and frequency of repairs. This configuration not only ensures crushing efficiency and effectiveness, but also saves users investment and operating costs in the long run. It is the preferred solution in the field of cobblestone crushing.

The impact crusher (sand making machine) re-crushes the stone (usually 30-60mm) that has been processed by medium and fine crushing (usually a cone crusher) until it reaches 0-5mm, which is commonly known as machine-made sand. In addition to being used to produce 0-5mm machine-made sand, the sand making machine also has an important shaping function. Modern high-quality commercial concrete aggregates have strict requirements for aggregate particle shape. The aggregates produced by conventional primary crushing plus medium crushing and fine crushing operations are generally not very round. At this time, in order to improve the grain shape, it is necessary to use a sand making machine to shape it.

To sum up, you can choose cone crusher and impact crusher (sand making machine) for cobblestone sand making. These two are ideal cobblestone sand making equipment.
