The 10-acre Quarry Garden is located at the center of Shanghai Chen Mountain Botanical Garden. An abandoned rock quarry was transformed into an ecological public garden. A rocky area near the entrance was transformed into a new “biocoenosis” – a self-regulating ecological community.

“Quarries want their primary blasted rock to be optimally fragmented, so that their crushers operate as productively and efficiently as possible. A presentation at the IQSA conference estimated that the added cost of secondary blasting or breaking of large boulders could reach four times the cost of the initial blast.”

Unless you’ve visited or toured a quarry, chances are you don’t know much about what goes on inside one. In the simplest terms, a rock quarry is a place where little rocks are made from big rocks. Although the basic process is the same, each quarry is different and some of the things in Quarry Story may not apply to all operations.

Tsurumi''s choice for quarry applications. Pumps are widely used in three main quarry operations: supplying process water, pumping slurry and mud, and site dewatering. For site dewatering, there are several factors that will determine the proper pump choice, such as vertical and horizontal discharge head and flow requirements.

High-energy explosives enhance fragmentation, which ultimately produces a positive effect on production costs. The degree of fragmentation or movement obtained is directly related to the amount of operation.
