Sandvik has launched its second generation of compact horizontal impact (HSI) crushers, and the company said that the CI511/512 crusher combined the ability to configure one base crusher into either a primary or a secondary configuration.

Sandvik said the new HSI crusher possessed a revolutionary chamber design resulting in greater reduction ratios. It claimed the crusher was able to produce products with two curtains, while competitors required three-curtain crushers to produce the same.

The CI511/512 is equipped with an infinite hydraulic curtain adjustment combined with a brake positioning system relieving pressure and setting when uncrushable objects enter the crusher. Sandvik said that no hydraulic power was required during normal operation, saving on operating power and reducing total power consumption.

It added that a key safety interlock system ensured safe maintenance of the crusher, especially in multiple installations.

The ability to raise curtains during operation without stopping the crusher to clear blockages and reset automatically to operating setting, maximised uptime and reduced the need for heavy lifting gear and operator and maintenance intervention, according to Sandvik, which added that it reduced further health and safety risks.
