Sandvik launches third generation impact crusher
By Leila Steed23 November 2021
Sandvik Mobile Crushers and Screens has launched its new 3-Series equipment line, starting with the release of the third generation QI353 impact crusher.
The third-generation Q1353 is a mid-sized tracked machine that has been designed for the recycling and contractor sectors.
It can process up to 400 t of material an hour and includes PRISEC crushing technology, which enables it to be used of both primary and secondary applications.
Sandvik said: “Its feed arrangement includes a new feed hopper with curved heavy-duty sides for greater capacity and tapered feed arrangement to reduce blockages and ensure continuous crushing. It also features a new pan feeder with geared drive and a larger pre-screen with improved access to replace media.”
“At the core of the QI353 is a new mid-size Prisec impact crusher, which boasts the largest feed opening 1,170 x 730 mm (46 x 29 in) and largest rotor diameter 1,150 mm (45 in) within its class, for higher capacity & greater energy efficiency,” said the manufacturer.
“Adjustable apron curtains and tip speed ensure a wide range of product gradations can be achieved. Also, all plant conveyors have larger discharge heights for increased stockpiling capacity.”
According to Sandvik, the mobile machine is “particularly useful for contractors who change jobs frequently” and has been designed for easy operator use.
It features an automated control system that incorporates the manufacturer’s new Optik interface. Optik comprises a colour display that integrates troubleshooting, diagnostic and support capabilities, as well as the My Fleet telematics system.
Unlike the manufacturer’s second generation models, the 3-Series QI353 has been equipped with a new access platform located under the feeder and pre-screen, and a three-sided 270-degree service and maintenance platform.
The 3-Series model is available with optional belt scales for tph (tonnes per hour) monitoring of fines and stockpile conveyors. Fitted to the machine’s conveyor, the scales allow productivity data to be displayed on the main user interface.
The QI353 also comes factory ready to accept Sandvik’s new HS323 hanging screen module, which enables operators to use the crusher in an open or closed circuit.
Sandvik said: “The HS323 enhancements include; prepared to accept belt scales for tph monitoring on fines and stockpile conveyor belts, subframe enhanced for improved screen media access and tensioning and an updated mid-size stockpile conveyor.”
“The unique design enables set-up in less than 30 minutes and can be fitted without the use of additional lifting equipment.
It added: “The patent pending hanging screen option delivers multi-functionality as a one, two or three-way split screener, as well as a highly productive and efficient impact crusher.”
