Sandvik Construction offers the all-new CI531 primary and CI532 secondary Prisec 3 Horizontal Shaft Impact (HSI) crushers. These new-generation crushers provide customers with a low capital cost solution, optimum performance and good cubical shape, while ensuring the lowest operating cost per ton for a wide range of materials and applications.
The latest additions to the CI500 Prisec Horizontal Shaft Impactor (HSI) range of crushers have been developed to deliver exceptional rates of productivity and efficiency. As with the rest of the Prisec range these new HSI crushers possess the ability to be configured into either a primary or secondary crusher operating mode and with this unique, exclusive to Sandvik, patented design, providing customers with unparalleled adaptability. Additionally single-stage crushing is also a possibility with the ability to recirculate material to the primary versions of the crushers.
Sandvik’s design of crushing chamber ensures even greater reduction ratios than have been previously obtainable. Furthermore the Prisec 3 crushers are able to easily produce impressive reduction ratios through the use of two uniquely designed curtains, which have traditionally required a three-curtain configuration crusher. As well as enhanced productivity, this means fewer wear parts and reduced maintenance.
The CI531 and CI532 Prisec 3 are equipped with an infinite hydraulic curtain adjustment combined with a brake positioning system which relieves pressure, and setting, when un-crushable objects enter the crusher. No hydraulic power is required during normal operation, thus saving on operating power and reducing total power consumption.
Crusher blockages have always historically been a problem, especially when operating in a primary mode. Removal of the blockage, with the combined downtime and health and safety risks encountered, are now eliminated with the new generation Prisec 3 crusher. No stopping of the crusher is necessary, with no operator intervention inside the crusher and no heavy lifting gear required.
The rotor and hammers have superior weight and design, essential for delivering the high inertia required for optimum crusher performance, thus ensuring stability and smooth operation during production. The unique “banana” shaped self-sharpening hammer design helps to keep the contact heads sharper during operation, resulting in more effective shearing of the incoming material, and hence improved production.
A unique key safety interlock system ensures safe maintenance of the crusher and prevents accidental opening of the crusher and inspection doors even in multiple installations.
