The new Powerscreen 1150 Maxtrak tracked cone crusher, designed to build on the success of the Powerscreen 1000 Maxtrak and 1300 Maxtrak cones, is undergoing extensive hard testing in Europe prior to its worldwide launch and is performing up to expected high levels, the company said. The mid-sized 1150 Maxtrak is targeted at quarry owners and contractors, and incorporates a number of new features. It should be available in North America later this year.
At a quarry test site, a Powerscreen system consisting of a jaw, two 1000 Maxtrak cone crushers and a Chieftain 2100 screen were used for crushing gritstone to produce 1/4-, 3/8- and 9/16-in. products. Since a 1150 Maxtrak replaced the first 1000 Maxtrak unit the system’s high production output has surged by an additional 30 percent.
In a second test application, the 1150 Maxtrak performs alongside a 1000 Maxtrak in producing a 6N hardcore crusher run product. The 1000 Maxtrak is producing 1,200 to 1,300 tpd. The 1150 Maxtrak is producing 2,100 tpd.
In both tests the crushing action of the 1150 Maxtrak is delivering the same exceptional product shaping and versatility for which the other Powerscreen cones have become known worldwide.
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 331Kw Scania DC 13 engine that complies with the latest Stage IV emission
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 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. Self-supporting legs for lowering to ground level and easy removal for service.
A highly compact transport envelope and two-speed tracking provide for quick, easy transport and on-site moving. Weight is about 48.25 tons without options. An intuitive control panel allows machine settings to be changed easily and provides diagnostics for fault-finding if required.
