Pre-screen increases crusher productivity

Sandvik Mobile Crushers and Screens introduces the Sandvik QJ341+, which incorporates a double-deck pre-screen as standard to its QJ341 jaw crusher. The new pre-screen is said to provide high amplitude for separation, enabling the unit to remove a large amount of fines for greater efficiency, higher productivity, and less wear. Sandvik says test results have shown an increase in productivity of as much as 30 percent in certain applications. A new telescopic natural fines conveyor — with a discharge height of 10 feet, 3 inches — deals with the increased flow of pre-screened material, while a dirt chute with a steeper angle allows faster transfer of material. The mobile crusher is available with a choice of Cat or Volvo engine and features a self-locking hopper for set-up from the ground level.

Retrofit kit enables remote control operation

Cat Command for loading enables line-of-sight remote control of Cat 988K Wheel Loaders and reduces the risk of injury in activities such as highwall and edge operations, stockpile feeding, and working on slopes and unstable surfaces. Available as a retrofit kit for 988K machines, the system features a compact control console supported by a shoulder harness. Ergonomic controls, common with the controls in the cab, give the operator full access to primary machine functions. The controls are integrated with machine electronics to provide the same control and responsiveness as if operating from the cab. Advanced options, such as Autodig, are accessible on the console, which works from as far as a quarter mile away from the machine.

Cone crusher feeder

Deister Machine Co., Inc. rolls out its EMCO 360 Crusher Optimizer Feeder, the latest in its line of electromechanical vibrating feeders. The unit is specifically engineered to optimize cone crusher performance. It features a 360-degree discharge opening and distributes a homogeneous feed to cone crushers to keep them choke-fed for improved efficiency, product consistency, and higher production rates.

Scrubs clay and other contaminants

McCloskey Washing Systems launches its Aggstorm Range, which is designed to operate as a stand-alone unit or integrate with one of its SandStorm wash plants. AggStorm is designed to manage various types of clay-bound material where aggressive scrubbing and washing, rather than simple screening, is required. Suitable for sand and gravel and C&D applications, the unit aggressively removes clays and silts, as well as any light debris.

Wider components
enhance material flow

Terex Finlay debuts its I-140 direct drive 50- by 48-inch horizontal impact crusher with variable speed. The CR032 chamber is said to give excellent reduction ratios and high consistency of product shape, while material flow through the plant has been enhanced by increasing the width of components. The machine features an electronic control system that manages the speed of the rotor and regulates the heavy-duty vibrating feeder with integrated pre-screen to maintain a consistent feed of material to the impact chamber. Material from the integrated pre-screen can be diverted to a stockpile via an optional by-pass conveyor, or it can join the crushed product on the main belt. The hopper capacity is 7.5 cubic yards.

Dozer boosts fuel efficiency

Caterpillar’s D6T Dozer features a new, fully automatic transmission to optimize performance and achieve fuel efficiency savings of up to 20 percent in heavy work and 30 percent in light work and finish grading applications. An additional gear between first and second allows the machine to remain in the most efficient mode for a higher period of time. The dozer is also said to be easier to operate — just set the desired ground speed, and the four-speed transmission will set the powertrain for optimum efficiency. The unit is powered by the Tier 4 Final Cat C9.3 Acert engine, which has a net power rating of 215 horsepower. Cat Connect Grade technologies, ranging from simple grade indicators to fully factory-integrated GPS, are available.
