Secondary splitting - large rocks reduced economically and rapidly
The Job:
In Danderyd, Sweden, a recycling plant performed the task of reducing large rocks from building sites in the surrounding district.
The Requirements:
Many of these boulders were so large that the recycling plant was unable to handle them itself. Explosives were therefore used to demolish them on a factory site. The problems presented in this case were as follows:
Explosives could only be used after stringent safety regulations.
It was necessary to move people, machines and vehicles into positions of safety.
When explosives were being used, even the recycling plant itself was at risk.
The Solution:
Instead of explosives, a Darda type C 3 N splitting cylinder and an electric motor unit was used to reduce the large pieces of rock. Advantages:
One worker could split 60 - 70 pieces of rock in an eight-hour shift.
The splitter could be used at any time. No safety measures were required.
The factory could operate uninterrupted resulting in substantial savings in costs and time.
