Powerscreen, one of the world’s leading providers of mobile crushing and screening equipment, launched the new Premiertrak 300 jaw crusher. Damian Power, Powerscreen global product director, said: “With its exciting new features and feedback from the testing period, we’re confident that the Premiertrak 300 will set new standards worldwide. The machine was recently showcased at a preview demonstration for distributors and customers and there was a lot of enthusiasm among the attendees.”
In advance of its launch, the Premiertrak 300 crusher received extensive testing in sites in the UK. One of the test sites was J. Gourley and Sons in Northern Ireland who crush medium hard quarry rock for local building contractors and farmers. Its representative, Thomas Gourley, said, “The Premiertrak 300 gets a five star rating from me. As a family-run company we are a relatively small team and any time and money savings can make a big difference. Its fuel efficiency is honestly second to none —when producing [2.5 inch] road base material it gave us an excellent tonnes per hour output to fuel efficiency ratio. In terms of fuel consumption, we found it outperformed crushers we have used from other brands by around 30 percent. This is in addition to the time saved by not having to stop production to refuel, and in this industry saving time is saving money, allowing us to do what we do best — keep producing quality material to meet our customers’ needs.
“The size of the machine for transport was another massive benefit. With the same output tonnage and finished product quality as other crushers we’ve used, we saved up to 70 percent in transport costs when moving the Premiertrak 300 between sites. I was delighted with this machine’s performance and would happily recommend it to anyone.”
The Premiertrak 300 crusher uses a 40 by 24 in. (100 by 60 cm) jaw chamber and is capable of producing up to 308 ton (280 t) per hour of crushed material. It has been developed with the option of a vibrating grizzly feeder (VGF) or a large fully independent hydraulically driven pre-screen, which improves fines removal and reduces chamber wear costs for the customer. Both options are proportionally controlled by engine load to maintain throughput.
To coincide with the independent pre-screen feature, an optional hydraulically folding extended side conveyor with a stockpile height of 10 ft. 2 in. (3.1 m) has been added to the machine to improve stockpile capacity.
The new bypass chute design incorporates a “flap gate” to allow the operator to switch between using the side conveyor or sending the material to the main belt without the need to fit a blanking mat on the bottom screen deck.
The Powerscreen jaw chamber has hydraulically adjustable closed side setting (CSS), which can be adjusted in a matter of minutes by a single operator without requiring tools. The hydraulic release chamber option (Premiertrak R300 crusher) incorporates the hydraulic release mechanism to allow the chamber to “dump” and pass un-crushable material which is ideal for recycling applications. A hydraulically adjustable deflector plate is an option for recycling applications. The machine is highly versatile as it also incorporates a new lock-out function to allow the operator to work in hard rock quarry applications with the same chamber, according to the manufacturer.
The new hopper design incorporates a complete hydraulic fold and lock system which removes the need for manual wedges and can be raised/lowered from ground level removing the need to work at height and providing rapid setup times. Full hopper extensions are an option to further increase capacity.
The Premiertrak 300 jaw crusher features a hydraulically lowering product conveyor with 11 ft. 6 in. (3.5 m) discharge height for easy removal of trapped metal in recycling applications and features full tunnelling to reducing snagging of rebar.
The machine has been designed with transport in mind, boasting a highly compact transport envelope which translates to savings on shipping costs and times. It weighs approximately 36.38 tons (33,000 t) and features two speed tracking for optimum mobility. An intuitive control panel allows machine settings to be changed easily and provides diagnostics for fault finding if required.
The Premiertrak 300 can be powered by a Tier III/Stage IIIA-compliant Cat C9 Acert 275 hp (205 kW) engine or a Tier IV Final compliant Scania DC9 80A 272 hp (202 kW) engine which is designed to run at the most economical speeds to reduce fuel consumption and noise pollution. Drive to the crushing chamber can be by either “Direct” clutch drive for increased fuel efficiency or via a hydrostatic system (Tier IV only) to allow the option of reverse running or unblocking. V- Belt adjustment on both variants is via a single adjustment screw which can be completed in a matter of minutes. Fuel efficiency coupled with a large fuel tank capacity allows for longer shifts between refuelling.
