Bauma 2019 marked the latest installment of the international construction industry trade show based in Munich, Germany.

The show, which occurs once every three years, took place April 8-14, featuring a record 3,500 exhibitors across more than 6.6 million sq. ft. With exhibitors and attendees from all over the world, Bauma showcased equipment of all types, including a range of crushing equipment – new, redesigned and previously released – from a variety of manufacturers.

Here’s a sample of some of the equipment manufacturers planned to showcase at Bauma:

New crushing equipment

The eccentric roll crusher (ERC), for example, was slated to be unveiled by thyssenkrupp, providing a new solution for the primary reduction of hard rock. According to the company, the ERC permits throughputs up to 8,000 metric tph due to its design with an integrated screen. With improved efficiency and flexibility, the ERC is applicable to both surface and underground mining operations.

Keestrack planned to showcase its 700-tph B7e jaw crusher on an international stage for the first time, replacing its smaller B6. The crusher’s core is a single-jaw crusher – the CJ 412 with a 1,200-mm x 830-mm inlet for feeding sizes up to 700 mm – and a hydraulically-adjustable closed-side setting range of 75 to 250 mm.

The B7e operates with low fuel consumption due to constant and low engine speeds, even under full diesel-electric load, the company says. In addition, the B7e, which is only available as a plug-in hybrid, is driven by a 132-kW electric motor. Another 55-kW electric motor powers the hydraulic system for the tracks, the lifting cylinders, the vibrating feeder with two-deck pre-screening, and all conveyors.

Separately, the new OMNI system, which Terex Finlay planned to preview at Bauma, provides telematics capabilities and interacts with mobile crushing and screening equipment, including the J-1160 jaw crusher.

A second-generation mobile jaw crusher, the J-1160 was designed and built with the customer and operator in mind, according to the company, with increased under-jaw clearance for serviceability access. The 40 in. x 24 in. jaw crusher is applicable to aggregate, demolition and recycling.

Also slated for Bauma was EvoQuip’s Cobra290R, the newest addition to the company’s crushing range. The Cobra 290R is a closed-circuit version of the Cobra 290 that incorporates a 2.74-m x 1.5-m post screen to ensure required product specification.

Applicable in a range of industries, the Cobra 290R uses a 315-hp engine to power the direct-drive system, which provides a potential throughput up to 290 tph. The 290R also features two independent hydraulic-controlled aprons that allow the operator to improve material throughput and reduction. In addition, the hydraulic overload protection system minimizes apron bounce and protects the crusher from undesired material entering the chamber.

A redesigned crusher expected to be at Bauma was Powerscreen’s Metrotrak compact jaw crusher. The crusher was redesigned with serviceability, maintenance and ease of use in mind, according to the company.

Ideally suited for the aggregate, mining and recycling industries, the Metrotrak includes a chamber unblock feature which, with the aid of a motor attached to the flywheel on the chamber, “rocks” the chamber back and forth until the blockage is cleared. The product belt conveyor was also upgraded with relocated belt-tensioning bolts to help keep the belt tracked.

Additionally, Telsmith planned to display its Hydra-Jaw H2238 jaw crusher at Bauma. The H2238 features throughput capacities ranging from 100 to 155 stph through 220 to 370 stph, and it’s suitable for aggregate, mining and recycling applications, according to the company.

The crusher is available in three different configurations: stationary, tracked and wheeled portable plants, and it’s part of Telsmith’s main line of Hydra-Jaw crushers. The H2238 was designed with safety in mind, and the hydraulic chamber-clearing system allows the crusher to start up in as few as 15 minutes following an emergency stop or power failure.

Also at Bauma, Kleemann planned to display seven different mobile crushing and screening plants. Among the plants expected to be seen was the Mobicat MC 120 Z Pro, which features an hourly output of 650 tons; the Mobicone MCO 11 Pro, which has a maximum hourly output of 470 tons; the Mobirex MR 130 Z EVO2 impactor, which features improvements in noise reduction and dust containment; and the MC 110 Z EVO and MCO 9 S EVO, both of which supplement the EVO line.

Another crushing-related development to be showcased at Bauma was Allu’s new and upgraded mobile app. According to the company, this is aimed at improving customer productivity and service, as well as jobsite safety. The latest development of Allu’s communication system, this digital solution provides accurate and timely information, according to the company.

Also at Bauma, Allu exhibited its TS blade structure, which features two fragment sizes and a new blade thickness of 8 mm.

Other Bauma debuts

Leading up to Bauma 2019, specifics weren’t provided for every piece of equipment set to debut in Germany. But at least two manufacturers provided a few intriguing details about their big Bauma plans in advance of the April 8-14 trade show.

Metso, for example, unveiled plans to introduce new crushing and screening equipment. According to Metso, its new solutions are designed for small and midsized aggregate producers and contractors to tap into new, emerging business opportunities. The solutions should help these users increase the performance of existing operations, as well as control cost per ton, according to Metso.

Separately, MB Crusher announced it “will reveal something truly revolutionary” at Bauma.
