Cobblestone is a collective name for all kinds of rocks that are impacted by the river bed and washed by rain, and wading quietly in the river body. Cobblestones are stones that are made up of various rocks. The hardness of pebbles is different, and its Mohs hardness is greater than 6.5 to 8. It can be seen that pebbles are a kind of river stone with high hardness, and it also has strict requirements for pebbles sand making machines.

Cobblestone also has certain processing and utilization value. Common cobblestone deep processing and utilization include:
1: Deep-processing cobblestones into oval stones for paving roads in gardens.
2: After the cobblestone is further processed by crushing → fine crushing → screening and other processes, it is formed into cobblestone machine-made sand, which is used for building filling aggregates.

Today, I will mainly introduce the technology and equipment for deep processing cobblestone into cobblestone machine-made sand. Cobblestones are processed into cobblestone sand making equipment usually include: jaw crusher (coarse jaw crusher and fine jaw crusher), impact crusher, roller crusher, third-generation sand making machine, circular vibrating screen and auxiliary equipment (vibration Feeders, belt conveyors, silos) and other mechanical equipment.

Because the cobblestone is hard, the cobblestone crusher must use a cobblestone sand making machine such as a jaw crusher. According to customer experience, the cobblestone is processed into machine-made sand generally first with coarse jaw crusher for coarse crushing, and then fine jaw crusher for fine crushing. , it is best to use the combination of coarse jaw crusher and fine jaw crusher. Here, Shanghai Shanmei recommends the choice of coarse jaw crusher: PE-400×600 jaw crusher model, and the fine jaw crusher model: PE-250×1200 jaw crusher model, because the output of these two models is consistent, just enough The crushing operations that make up the cobblestones.

Expert advice: The cobblestone has high hardness, and the cobblestone crushing equipment must choose the best crushing scheme combining coarse jaw crusher and fine jaw crusher, otherwise, the cobblestone will cause great loss to your cobblestone crushing equipment.

So why must the jaw crusher equipment be chosen as the cobblestone sand making machine?

This is determined by the working principle of the jaw crusher. The ore material is crushed mainly by the squeezing, pressing and rubbing of the dynamic and static jaws. For details, please refer to the following demonstration diagram:
