38 • ROCK products • May 2018 www.rockproducts.com Crushing Feature Metso The Metso MX cone crusher is based on the patented Multi-Action crushing technology, which combines the piston and rotating bowl into a single crusher. The new crusher provides a giant leap in profitability by cutting operational costs 10 percent and enabling 10 percent higher uptime compared to traditional cone crushers. Features include: •  Up to 70 percent wear part utilization. Optimal cavity design, stroke direction and an effectively distributed crushing action lead to the ultimate rock-on-rock crushing motion. •  Multi-Action technology. The Metso's patented Multi-Action technology is a revolution- ary way to optimize the crusher setting and wear compensation in real time, requiring no human actions. •  Selective production. The smart optimization of Multi-Action technology is the key advantage to reach the desired end-product shape and particle size distribution while eliminating waste. • Safe and simple. Metso MX is designed to be the safest cone crusher to operate and maintain. During the crushing operation, all moving parts are inside the crusher. Lifting devices and hydraulic tools make maintenance simple and safe. Metso, www.metso.com REMco In the past, the limits on impact crushers have been their high cost to operate when the material is hard and abrasive. Historically, hard rock such as granites, quartzite and other materials with high abrasives content have caused severe wear on the crushing members of vertical shaft impact crushers making them prohib- itively expensive to operate. REMco VSI RockMax crushers are autogenous vertical shaft crushing machines designed to operate as third stage crushers in the processing of all types of rock, ores and minerals. RockMax crushers can be operated in either open or closed-circuit. Closed-circuit operation is recommended in order to achieve the lowest net operating cost, best particle shape and the highest production. RockMax crushers are intended for pro- ducing crushed products between 1 ½- to 3/8-in. REMco, www.remcovsi.com Sandvik Targeted at the most demanding of aggregate producers, the compact Sandvik QS331 has been designed to accept large feed sizes and achieve high production capacities. This produces benefits for customers by deliver- ing improved productivity on such applications as Type 1, crusher run or in primary gravel crushing. The "S" type gyratory cone crusher has been incor- porated into a self-contained, diesel driven track-mounted plant, providing producers with superior performance and high product quality, but in a fully mobile version. Many direct customer benefits are delivered as the "S" type gyratory cone is able to accept a feed size up to 90 percent larger than current standard cones. This enables maximum productivity to be enjoyed from your primary crusher, or even facilitates the use of the "S" cone as a primary crusher itself on gravel applications. The Sand- vik CS430 cone crusher truly sets the 36-ton mobile Sandvik QS331 apart: with a choice of three concaves, and four bush settings to control the closed side settings and material gradation, the Sandvik QS331 delivers ultimate flexi- bility. Due to the large feed acceptance, jaw crusher production may be opti- mized by opening the CSS, thereby also reducing fuel consumption and wear. Sandvik, www.sandvik.com
