What makes Sandvik impact crushers market-leading? With patented chamber design, flexible configurations, and high-quality wear parts, Sandvik impactors are an excellent choice for high-impact production.
The patented Prisec™ crushing chamber has been designed by Sandvik to enable the base crusher to be easily switched between primary and secondary mode, thereby giving the customer virtually two machines from one unit. The two hydraulically assisted curtains can be readily adjusted to allow the production of a wide range of high-quality product sizes.
ENERGY EFFICIENT OVERLOAD PROTECTION
Sandvik Prisec™ impactor chambers are equipped with an infinite hydraulic curtain adjustment combined with a brake positioning system that 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. Both first and second curtains are infinitely adjustable via Sandvik’s patented adjustment/braking system which is located on the cross beams of the crusher. This system gives hydraulic adjustment of both curtains, via the standard supply electric hydraulic power pack.
DEALING WITH CRUSHER BLOCKAGES
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™ crusher. Due to the exceptional features of the crushers, no stopping of the crusher is necessary, with no operator intervention inside the crusher, and no heavy lifting gear required, all resulting in maximum uptime and reduced health and safety problems.
ROTOR AND HAMMER DESIGN
The rotor and hammers can be considered the heart of the crusher; this is why those used on the Prisec™ range are both robust and efficient. Rotors 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.
EASY & SAFE MAINTENANCE
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. It also allows the ability to raise curtains during operation without stopping the crusher to clear blockages and re-set automatically to the operating setting. This maximizes uptime and reduces the need for heavy lifting gear and operator/maintenance intervention, thereby reducing further Health & Safety risks.
MAXIMUM UPTIME, MAXIMUM BREAKAGE
Through the modularized nature of the Prisec™ range, wear parts can be turned for maximum life/usage with the same size being used across the whole range of crushers. In addition, Sandvik’s world-leading technology in the hammer and liner material composition provides options far surpassing the old industry standards of manganese, resulting in even lower operating cost per ton and the ability to operate efficiently in a variety of materials, especially recycling applications.
