The new Powerscreen tracked cone crusher is designed to build on the success of the Powerscreen 1000 Maxtrak and 1300 Maxtrak cones. The mid-sized 1150 Maxtrak is targeted at quarry owners and contractors, and incorporates a number of new features, according to the company. It should be available in North America later this year.
The new machine will be offered in two key configurations: a direct feed model and a pre-screen version that enables operators to achieve higher production rates with dirty feed material. With a choice of strokes and four liner options – all compatible with a single upper frame – the 1150 Maxtrak can be easily configured for virtually all applications.
Feed sizes of up to 8.1-in. are possible with the 225kW cone chamber. Power is supplied by a fuel-efficient 331-kW Scania DC 13 engine that complies with the latest Stage IV emission regulations.
The pre-screen model features a patented hydraulic folding system that converts the machine to a direct-feed layout in minutes. A new bypass chute design incorporates a “flop gate” to allow the operator to switch between using the optional side conveyor or sending material to the main belt.
The belt feeder is designed for durability and optimized material flow. A fully lined tapered hopper with a standard capacity of 6 cu. m and a low feed-in height and optional extensions allows the machine to be fed by any primary crusher or directly with a loading shovel.
The cone feed-in box has an ultrasonic level sensor and optional monitoring camera to help ensure the chamber is being continuously choke-fed for optimal throughput and minimal wear. Liner wear rates can be further reduced with an optional anti-spin system for the cone head.
The 39-in.-wide product conveyor with raise/lower function provides easy maintenance and access to the cone underside. It is also designed with self-supporting legs for lowering to ground level and easy removal for service.
