How do stone breaking & rock breaking differ from blasting?

Simplex is a cartridge based on a blasting powder specially developed for breaking stones. The powder in the cartridge has a burn speed of approximately 350 m/s, which can be compared with the approximately 6,000 m/s that dynamite has. This low burn speed of the powder results in a minimum of vibration being created. Earlier cartridges manufactured by Power Tools had the electrical igniter integrated into the cartridge. The company has continued development of its cartridge to increase safety, leading to today’s Simplex cartridge. The Simplex system consists of a cartridge and a separate electrical igniter. These are united, and the cartridge then becomes “live” just before the breaking operation. This increases safety not only during handling of the product, but also during transport and storage.
