60 tph River Stone Crushing Plant
This client wanted to purchase a river stone crushing line. The feed material is approximately 400 mm, and the client required it to be crushed into three sizes: 0–5 mm, 5–19 mm, and 19–38 mm, producing both gravel and fine sand. These construction aggregates are to be used in the construction of a hydropower plant. Additionally, the client requested that, based on production needs, the 19–38 mm output material could be recrushed to obtain the other two sizes: 0–5 mm and 5–19 mm.
Based on the client’s overall requirements, MR selected a jaw crusher for the primary crushing stage and a spring cone crusher for the secondary crushing stage. For the 19–38 mm material that required further crushing, a sand making machine was provided. The complete system has been in continuous operation for over three years, and the client is very satisfied with both the production output and the particle shape.

Concerns and Solutions
Concern 1:
Do you provide the cables for these equipment?
MR Solution 1:
The cables are to be purchased locally by the client. We will provide the cable specifications:
Question 2:
If we want to adjust the output by recrushing the 19–38 mm material to increase the production of 0–5 mm and 5–19 mm materials, how can this be addressed?
MR Solution 2:
Add another VSI sand making machine along with a corresponding hopper and vibrating feeder. Feed the 19–38 mm output into this sand making machine, then screen it through a vibrating screen to obtain 0–5 mm and 5–19 mm materials.
Equipment Delivery
During loading, for equipment with a high center of gravity such as jaw crushers, sand making machines, and cone crushers, MR places the equipment upright first and then secures it by diagonally tensioning steel wire ropes from the base. For critical parts of the equipment, MR’s workers carry out separate packaging or apply a protective film over the equipment to prevent rust on key components.
After-sales service
Upon arrival at the client’s project site, MR’s engineers provide full guidance to the client’s workers throughout the equipment installation process. Special attention is given to the foundation work—the engineers and workers verify the dimensions, position, and height of the foundations before proceeding with pouring. Prior to installing the belt conveyors, the angle and installation position of each conveyor are also confirmed. The involvement of MR’s engineers ensures the smooth progress of the project installation.
Customer Comments
MR is very professional! When we communicated the project plan to MR, they recommended a jaw crusher for primary crushing and a cone crusher for secondary crushing based on our 60 tph output requirement and the three required sizes. When they learned that we needed to recrush the 15–39 mm output according to actual production demands, MR promptly recommended a sand making machine for this purpose. The overall solution was very well-designed and perfectly met our needs.
The installation of the entire equipment went very smoothly as well. The production line has now been in continuous operation for over three years, and the equipment quality is excellent!
