Terex MPS unveiled its latest crushing and screening solution at ConExpo-Con/Agg 2020 in the portable CRH1113R closed-circuit impactor crusher/screen plant.

The CRH1113R features a brand-new crusher, screen and feeder – all designed to maximize production of the machine, Terex MPS says.

Portable design

Designed as a one-piece tow, the portable crushing and screening solution is easy to transport on a highway or move on a jobsite, the company says.

Hydraulics on the screen and return conveyor offer quick, easy and safe setup. The machine is self-contained with onboard diesel power and a generator. The 450-hp variable-speed Scania diesel engine direct drives both the crusher and the 150-kW generator with an efficient hydraulic clutch, Terex MPS adds. The rest of the plant is electrically powered for maximum efficiency and minimal maintenance.

High production

In addition, the plant’s new TI4250 crusher has modern hydraulic-controlled curtains to make adjustments and maintenance safe and quick.

The variable-speed diesel allows optimum rotor speed to best match the application and desired product.

Also, the new 6-ft. x 16-ft. two-deck screen is the largest in this plant class, according to Terex MPS, and has a unique dual-slope design with a steeper top deck to handle heavy loads and quickly stratify material. The lower deck has less slope to increase retention time for maximum screening efficiency, and the entire screen can be positioned with more or less slope to optimize production.

The new vibrating grizzly feeder is 4 ft. wide x 18 ft. long to handle feeds from large loaders. This feeder has a convertible 6-ft.-long, two-section grizzly that easily converts from stepped grizzly bar sections to sloped punch plate sections, or a combination of punch plate and grizzly bars.

Maintenance friendly

The CRH1113R plant also incorporates a number of maintenance-friendly features to make maintenance safe and easy with minimal downtime, Terex MPS adds.

The all-electric drives provide long, low maintenance life, the upper cross conveyor rolls away for quick and safe access to the second deck screen cloth and the overhead conveyor rises hydraulically to give access to top-deck screen cloth.

Additionally, there are work platforms surrounding the screen and access from the ground to areas around the main frame. An optional hood scoop feature pulls radiator air from above the heavy dust-laden air at ground level and also greatly reduces ground level engine and fan noise, Terex MPS says.

“The CRH1113R is the result of customer input and recognizing the need for a highly portable plant that offers higher production and greater value than what’s on the market today,” says Ed Sauser, Terex MPS product manager. “The brand-new crusher, large screen and feeder, and low-maintenance electric-driven components make this one-piece towable machine a great value for processing shot rock, as well as concrete and asphalt recycle materials.”
