High throughput crushing: the Sandvik QI442 Mobile Impact Crusher.
The QI442 is a heavy-duty, self-contained track mobile impact crusher which features the unique Sandvik CI621 Prisec impact chamber. This offers unparalleled flexibility through the ability to work in both primary and secondary applications.
This newly developed impactor comes with a host of innovations for improved efficiency and greater safety during maintenance. This includes a new patented rotor locking and positioning device for controlled rotor movement during maintenance.
Key Benefits Include:
- The Sandvik Prisec impactor is the most flexible impactor currently available on the market designed to meet end-product specifications.
- The machine is fitted with a pre-screen to extract any undersized material from the feed passing through the impactor, thereby maximizing throughput and reducing wear costs. A further sellable, sized product can be produced using the natural fines conveyor.
- The pre-screen has a choice of grizzly or punch plate top deck and mesh bottom deck providing the flexibility to suit any application.
- Heavy-duty underpan feeder with wear-resistant liners transfers both the bypassed material from pre-screen and high-velocity material from the rotor onto the product conveyor in a controlled manner.
- Two hydraulically adjustable apron curtains can be positioned to produce a wide range of material, product sizes, and specifications.
- The above combined with the variable engine speed gives a tip speed range of 34 m/s to 42 m/s resulting in a wide range of product gradations being achievable.
- Capable of operating in the most hostile environments with a 50°C ambient temperature capability without any oil changes.
- Modular double deck hanging screen available to provide a 1, 2, or 3 way split.
- The modular double deck hanging screen can be quickly detached to operate in an open circuit.
- Fitted with My Fleet remote monitoring system as standard for live monitoring of plant, hours, location, etc.
