Screens and Crushers on the Move
Fintec Crushing & Screening Ltd.
Fintec says its 542 track-mounted mobile screen is robust and highly durable. The machine is carried on a heavy-duty tracked undercarriage with 20-inch-wide tracks that provide maneuverability and stability. The screen incorporates a large-capacity 12- by 5-foot two-bearing screenbox with increased screening angle built into the bottom deck. The unit’s belt feeder has a large capacity and is fitted with a radio-controlled tipping reject grid. A folding access walkway around the screenbox provides easy maintenance access. Other features include a quick-release screen section on the high impact zone of the top deck, pendant track control, heavy-duty belts on all conveyors, and Engine Shut Down Protection System.
Mobile jaw crusher
Komatsu’s BR580JG-1 Mobile Jaw Crusher has a newly designed vibrating grizzly feeder and an all-hydraulic drive system. The crusher has an EPA Tier 3-certified electronically controlled high-pressure common rail fuel-injection system. The machine is equipped with the latest Komtrax technology, which sends machine operating information to a secure Web site using wireless technology. Data such as operating hours, location, cautions, and maintenance alerts are relayed to the Web application for analysis. The automatic discharge system makes it easy to change the opening of the discharge port. All operation switches are located at ground level on the main control panel. A one-touch start button sequentially starts the operation of the magnetic separator, belt conveyor, jaw crusher, and feeder.
Rubble Master Systems Inc.
New class mobile processing
Rubble Master says its compact RM100 recycler is versatile, powerful, and stable, and can be transported without special permits. Transport weight is just 31 short tons. Features include a crushing capacity up to 220 short tons per hour with 1 1/2-inch minus final product; radio-controlled release system that clears blockages at the push of a button; and high-performance, wear-resistant crushing tools. The company says the machine has the ability to handle any material in any environment.
Continuous-flow crushing plant
Lippman-Milwaukee says its new Lippmann 6500LP Crushing Plant offers a revolutionary flow design and other features that can result in twice the production of competitive plants. A larger feeder, larger impact crusher, and larger screen deck combine to make the machine the highest producing plant for its size in recycle crushing, says the company. A continuous-flow design allows material to discharge smoothly with the rotation of the rotor for uninterrupted production. A heavy-duty pan feeder under the crusher prevents conveyor belt damage. On-board return conveyors mean that only two pieces of equipment, instead of four, need to be moved to the jobsite. Setup and tear down are fast and easy.
Vertical shaft crusher
The Remco SandMax 500-ST crusher is an autogenous vertical-shaft crushing machine designed to operate as a third or fourth stage crusher in the processing of all types of rock, ore, and minerals. The crusher can be operated in either open- or closed-circuit (closed-circuit is recommended for lowest net operating cost and highest production rate of any given size below 1/2 inch). The 400-horsepower machine has a feed size of 1 1/2-inch by #4 mesh and a production rate of 130 tons per hour.
Astec Mobile Screens
Astec Mobile Screens says its PEP Duo-Vibe, high-frequency screen is incorporated into the heavy-duty Fold ‘n Go Series of mobile screening plants via the Fold ‘n Go 2612D. The unit offers a double-deck PEP scalper/high-frequency combination screen for processing coarse and fine material separations. The machine gives maximum production and efficiency in crushed stone, RAP, sand and gravel, and more, according to the company. The company says the wheel-mounted plant is able to move around to multiple jobsites with a quick setup time of under 15 minutes.
The Powerscreen Warrior is a machine capable of dry screening, three-way splitting, and stockpiling. The screen box can be raised/lowered hydraulically for easy maintenance. Several sizes of screens and wires can be bolted in easily. The side conveyor can be removed to allow the unit to be converted to a two-way split machine with two products on the tail conveyor. The radial fines conveyor can move up to 180 degrees for greater stockpiling capabilities. The incline/horizontal belt-feed hopper discharges onto the screen box from above, spreading the material on impact and allowing it to flow more equally over the screen. Other features include hydraulic folding conveyors, hydraulic screen angle adjustment, hydraulic retractable oversize conveyor for ease of mesh change, hydraulic folding hopper sides, a screen walkway, engine protection shut-down system, and integrated variable-speed belt feeder. The machine sets up in about 20 minutes and can screen up to 550 tons per hour, according to the company.
