In the sand and stone production process, we will inevitably encounter some “hard bones” that is, stones with high hardness, then if you blindly choose the equipment for crushing treatment, it is easy to have equipment failure or accelerate the loss of equipment, then how to break the hard stone, which crushing equipment is more suitable? How much for one? The following will give you a detailed introduction.
First, hard stone’s Nemesis – cone crusher
Cone crusher is a kind of crushing equipment, which is widely used in sand and stone production line, and often does two level of medium and fine crushing processing. Cone crusher is more suitable for crushing and processing of hardness materials with compressive strength not exceeding 350MPa. Therefore, hard stones such as broken granite, basalt, river pebbles, marble and so on are completely no problem.

Second, the advantages of hard stone crushing equipment
Why is the cone crusher the ideal equipment for hard stone crushing? What are the performance benefits? Because there are more cone crusher models, the performance characteristics of different models are slightly different, so the next is to analyze the Sandro CHS single cylinder hydraulic cone crusher as an example:

1. High production efficiency and strong carrying capacity:
   The operation of the equipment depends not on the optimal design of the individual components or the improvement of the quality of the materials of the individual components, but on the coordination of the overall structure. CHS series single-cylinder hydraulic cone crusher achieves high efficiency and high quality by matching the crushing chamber type, eccentricity and motion parameters.
   2, easy to maintain and low operating cost:
   The structure of the equipment is simple, and all maintenance work can be completed after taking off the upper frame, which not only makes the inspection and maintenance more convenient, but also makes the maintenance cost lower. The positive pressure dust-proof system ensures that the internal pressure of the crushing chamber is always higher than the external pressure, effectively reducing the dust or other small particles entering the crusher, reducing the damage to the bearing, thereby reducing the maintenance workload, and extending the service life of the lubricating oil and equipment. In addition to the above features, CHS series single-cylinder hydraulic cone crusher overall compact design, crusher installation space is small, easy to move.
   3, fully automatic control of production side:
   Automatic control system provides manual control, constant discharge port control, constant power control and other operating modes for users to choose.
   It can continuously monitor the actual load inside the crusher and automatically adjust the equipment, so as to optimize the utilization rate of the crusher, so that the crusher can play its performance at any working time.
   Can automatically monitor and provide alarm, display various operating parameters, real-time understanding of crusher operation. For example, when the liner is worn to the replacement period and can no longer be used, it will automatically display and alarm on the control panel.
   4, multi-cavity type to meet a variety of process needs:
   The equipment has two models of medium and fine crushing, each model has a variety of standard cavity types to choose from, and the eccentricity can be adjusted by replacing the eccentric sleeve. According to different production processes, equipped with appropriate production cavity and eccentricity.
   The CHS series single cylinder hydraulic cone breaker is suitable for two-stage crushing after coarse crushing, and is also the choice of three and four stage crushing.

There are significant differences in price between different models and configurations of cone crushers. The price range of cone crusher on the market ranges from tens of thousands to hundreds of thousands of yuan, the specific price depends on the type of equipment, configuration and brand. In general, the higher the configuration, the more comprehensive the function of the cone crusher price will be higher. If you want to know the specific price of the crusher, welcome to call or online consultation, message, Leitos machinery will send professionals according to the needs of the configuration of your equipment and quotation.
