CRUSHERS AND SCREENS FOCUS ON MOBILITY AND PRODUCTION

from Heavy Equipment Guide April 2023, Volume 38, Number 4

The aggregate industry is always on the lookout for ways to improve efficiency in the quarry, and at CONEXPO this year trends leaned toward productivity increases thanks to updated designs and more throughput. Manufacturers made an impact with crushers and screens of all kinds, which featured greater mobility, electrical operation, and other updates that come together in more efficient and profitable machines.

Mobile Impact Crusher From Anaconda

The newest mobile impact crusher from Anaconda is an option for quarries and recycling operations. The I12Rv3 Impact Crusher, a midsized machine, is powered by a Cummins L9 Performance engine. It features a 43-inch-diameter, 4-bar rotor on a 45-inch-wide Universal Crushers Impact Chamber. A large hopper area and aggressive vibrating pan feeder with a two-tier grizzly section ensure movement of feed material to the impact chamber while removing fines and smaller dirt. Equally sized 12-foot decks top and bottom make up the 12- by 5-foot double-deck screenbox.

Tracked Cone Crusher From Finlay

Crusher owners and operators want high capacity from their cone crushers, and Finlay says its C-1550+ Tracked Cone Crusher has proven that ability through the development process. Built around the Terex 1300X Cone Crusher, the C-1550+ features an accessible power pack surrounded by large catwalks for quick access, along with mechanical and common upper frame designs for easy maintenance. The hopper folds hydraulically and locks in place from ground level for efficient set-up and teardown.

FULL ELECTRIC PLUG-IN KEESTRACK IMPACTOR

Keestrack’s focus on electric plug-in machines continues with the R5E impact crusher.

The R5e can plug into a mains connection or be run by a genset. It is available with a removable engine that can be used to power the crusher and other equipment as well. The R5e processes up to 440 tph. The crusher has an inlet opening of 31 by 41 inches and is driven by a 200 kW electric motor. It is fitted with a double-deck pre-screen as well as a two-deck precision screen that can be placed in closed circuit.

Terex Mps Adds New Portable Cone Plant And Screen

The new CRC 1350S portable plant from Terex MPS is mobile and built around the TC1300X cone, a 400-hp crushing unit with high-efficiency roller bearings. It’s paired with a TSV7203P 7-foot-wide three-deck horizontal screen which increases throughput and product shape. Also new is the ESX620 horizontal screen, which has greater clearances between decks for easier access to screen media. It features updates to the drivetrain and suspension.

SUPERIOR’S CLOSED CIRCUIT PLANT PRODUCES UP TO FOUR PRODUCTS

Versatility is key for the new Superior Industries Portable Sentry HSI Closed Circuit Plant, which is designed to crush a variety of materials and produce up to four unique products out of a single feed. Built around a Superior 4250 Sentry horizontal shaft impactor, the plant is fed by a 48- by 18-inch Intrepid Vibrating Grizzly Feeder equipped with interchangeable cassettes. A two-deck Anthem inclined screen sorts up to three material sizes with returning material fed back via a recirculating conveyor.

Kleemann Screen Optimizes Material Flow

Making its first appearance in the U.S. was the Kleemann MOBISCREEN MSS 802i EVO mobile screen for coarse elements. The plant’s design and conversion options provide optimal material flow of natural stone and recycled material. Adapting the MSS 802i EVO to new application conditions can be done with a broad range of screen surfaces and screening parameters. For example, if there’s a need for a fine final product to be screened from coarse feed, a quick conversion from three to two final grain sizes can be done.
