Powerscreen expands cone crusher range

November 2014

Powerscreen, one of the world’s leading providers of mobile crushing and screening equipment, has added a new member to its cone crusher range with the new mid-sized Powerscreen 1150 Maxtrak.

Targeted at quarry operators and contractors alike, the 1150 Maxtrak builds upon the success of the 1000 Maxtrak and 1300 Maxtrak models offering high performance, production and versatility. 

The crushing action of the 1150 Maxtrak model also delivers the same superb product shaping for which the other Powerscreen cones have become world-renowned, says a spokesman for Powerscreen.

Commenting on the new launch, Powerscreen Global product director Damian Power says: “Packed full of new features, the 1150 Maxtrak crusher will continue to push the boundaries in the crushing and screening industry. Due to the feedback we have received during testing, we have every confidence that this machine will be a success.”

The machine will be offered in two key configurations: a direct feed model and a pre-screen version which enables customers to handle dirty feed material and achieve higher production rates.

With a choice of strokes and four liner options, which are all compatible with a single upper frame, the 1150 Maxtrak cone crusher can be easily configured for all applications. Feed sizes of up to 205 mm are possible with the 225-kW cone chamber, which is driven directly by a fuel-efficient 331-kW Scania DC 13 engine that complies to the latest Stage IV emission regulations.

Power says one of the most impressive features of the pre-screen model is the patented hydraulic folding system, which converts the machine into a direct feed layout in minutes, delivering unparalleled flexibility to the end-user.

Along with the pre-screen, a new bypass chute design incorporates a ‘flop gate’ to allow the operator to switch between using the optional side conveyor or sending the material to the main belt.

The robust belt feeder is designed for durability and optimised material flow. Thanks to a fully-lined tapered hopper with a standard capacity of 6 cu m, and a low feed-in height and optional extensions, the machine can be easily fed by any primary crusher or directly with a loading shovel.

The cone feed-in box incorporates an ultrasonic level sensor and an 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 the optional anti-spin system available for the cone head.

The 1,000-mm-wide product conveyor includes a hydraulic raise/lower function to provide easy maintenance and access to the cone underside. It is also designed with self-supporting legs so that it can be lowered to ground level and easily removed for service.

“The 1150 Maxtrak cone crusher is designed with transport in mind, boasting a highly compact transport envelope which translates into savings on shipping costs and times. It weighs approximately 43,770 kg without options and features two-speed tracking for excellent mobility. An intuitive control panel allows machine settings to be changed easily and provides excellent diagnostics for fault finding, if required,” says Power.

The machine is being put to the test in the UK by Crush, a quarry operation, in preparation for its launch soon. While on site at its quarry in Wales, Crush has been primarily using the 1150 Maxtrak unit for the crushing of gritstone to produce 6-mm, 10-mm and 14-mm chips on final products.

Ben Sherratt from Crush says: “Typically, we had been using a crushing and screening train consisting of a jaw, two 1000 Maxtrak cone crushers and a Chieftain 2100X screen. When the 1150 Maxtrak cone crusher was substituted for the first 1000 Maxtrak unit, the plant’s output surged by an additional 30 per cent.”

In a second application, Crush has been using the 1150 Maxtrak crusher to produce a 6N hardcore crusher run product.

Sherratt says: “With the 1000 Maxtrak unit in this application, we had been producing around 1,200 to 1,300 tonnes per day. With the 1150 model, we are now at 2,100 tonnes per day.”

Powerscreen is part of the Terex Materials Processing segment of Terex Corporation, a lifting and material handling solutions company reporting in five business segments: aerial work platforms, construction, cranes, material handling and port solutions and materials processing.

The company manufactures a broad range of equipment serving customers in various industries, including the construction, infrastructure, manufacturing, shipping, transportation, refining, energy, utility, quarrying and mining industries.
