CRUSHING & BREAKING EQUIPMENT & TECHNOLOGY Metso's new Nordberg C130 jaw crusher can process more rock in the crushing process, owing to a larger cavity volume that helps deliver higher production in high‐capacity primary crushing, accord‐ ing to the company. The machine is tar‐ geted to demanding quarrying and mining applications. The cavity volume of a jaw crusher has a big impact on the efficiency of the crusher. The Nordberg C130 jaw crusher has a 21 percent larger cavity volume in comparison to previous models in this size class. The larger cavity volume means that more rock or ore is in the crushing process at one time. The C130 is a 40‐ton jaw crusher and features Metso's pinned and bolted de‐ sign for reliability, long life and easy service. Reliability, crushing efficiency in stationary and mobile applications, uncompromising safety and ease of use have been the key parameters while designing this jaw. "Our C130 really stands out of the crowd with its bigger cavity volume. In fact, the cavity is larger in all three di‐ mensions: deeper, wider and longer. Consequently, the new cavity can process over 20 percent more material increasing crushing capacity signifi‐ cantly," said Ilkka Somero, Metso's product manager for jaw crushers. Large Feed Opening Saves Blasting Costs The large, 39‐ x 51‐in. feed opening of the C130 jaw crusher is able to process even the coarsest feed and maintain a trouble‐ free material flow through the crusher, the company said. This results in savings in blasting costs and allows the process‐ ing of coarser feed at the primary stage. "This new design combined with a 160‐ kW (200‐hp) power range, a small nip angle and excellent kinematics ensures aggressive crushing along the whole length of the crusher cavity," Somero added. Thanks to the compact design, older crusher models can be easily replaced with the C130. The pinned and bolted de‐ sign also makes it possible to disassem‐ ble the C130 and transport it even to the deepest underground mines. Safety is one of the key focus areas for Metso when designing a new crusher. The C130 features optional, easy‐to‐ open composite flywheel guards that allow quick and safe access to all serv‐ ice points. The standard delivery in‐ cludes lifting tools for jaw dies, cheek plates and a toggle plate, all contribut‐ ing to operational safety. Easy to Customize with Options The Nordberg C130's operating speed is 220 rpm and the closed side setting be‐ tween 4 and 10 in. The operational weight is 88,500 lb., excluding options. In addition to the composite guards, the new C130 can be customized to any ap‐ plication with options such as a wear‐ protected feed chute, an integrated motor bed with electric drive, a hydraulic setting adjustment, a rock breaker and a boom combination, and an IC1000 process automation package.

Atlas Copco created the ES Range as an econom‐ ical and user‐friendly option for general construction projects and light demolition. Kevin Loomis, business line manager for Atlas Copco Construction Equipment, said the compact, ES hydraulic breakers are easy to maneuver into tight spaces and provide good visibility, which speed up day‐to‐day construction, landscaping and renovation jobs. "The ES Range breakers are a great ad‐ dition to Atlas Copco's family of SB, MB and HB breakers," Loomis said. "Atlas Copco hydraulic breakers have unparal‐ leled quality and service that customers expect from an equipment manufacturer. Our breakers help increase our cus‐ tomer's productivity and efficiency, while minimizing costly downtime." The new ES Range includes three mod‐ els, the ES 60, ES 70 and ES 80. These models are remarkably narrow to pro‐ mote good visibility and handling on worksites. The slim design also results in faster cleanup. For example, operators can cut narrow and precise trenches for plumbing installation applica‐ tions without removing excess soil to accommodate the breaker's size. Atlas Copco designed the ES breakers with a central lubri‐ cation point that can quickly and easily allow access to grease the breaker. The break‐ ers also feature full‐length floating bushings to ensure grease fully coats bushings and tool steel to minimize wear. Atlas Copco, www.atlascopco.com
