Secondary crushing for high-volume sites

Johnson Crushers International’s Kodiak K500+ crusher is a 500-horsepower, remote-adjust cone crusher suitable for secondary and tertiary crushing of high-production operations. The Kodiak line, including the K200+, K300+, and K400+, features a hybrid cast/fabricated base frame design, automated control system, patented liner retention, patented thread locking ring, and anti-spin cone brake. The line also includes replaceable brass thread inserts, patented internal counterweights, a heavy-duty tramp iron system consisting of pressure relief valves rather than accumulators, and brass v-seat liners.

New crushing line for natural stone

With its PRO line, Kleemann is developing plants to meet the needs of natural stone processing. The Mobicone MCO 11 PRO, the first crushing plant in the PRO lineup, can process up to 518 short tons per hour. The diesel-electric drive is said to be efficient, to offer the option of an external power supply, and to create excellent linkage options with other crushing and screening plants. The fully automatic gap setting makes it possible to make adjustments during operations. The Continuous Feed System adapts the feed conveyor to maintain an optimal filling height, while a brand new operating concept incorporates all components and functions within a 12-inch touch panel.

High throughput capacity

McCloskey International says the C44 Cone Crusher demonstrates its focus on quality components, durability, and reliability. With its 44-inch cone and 440-horsepower power unit, the C44 offers high material capacity and throughput, large stockpile capacity, an excellent reduction ratio, and customer-focused features. The unit’s crushing chamber is built to be reliable in the toughest conditions, producing material ranging from 3/8 inches to 8 inches. The cone can be used as a standalone crusher or in conjunction with other machines as part of a crushing circuit.

Effective compression crushing reduces wear

McLanahan’s MSP Cone Crusher utilizes improved factors of performance to enhance the proven Symons Principle. This principle, combined with a balanced eccentric, higher speeds, fulcrum point position, and stroke, allows the MSP to outperform other cones, McLanahan says. By creating more effective compression crushing, the MSP Cone Crusher reduces liner wear, reducing wear costs, allowing higher product yield, and resulting in decreased overall cost per ton. The patented dust seal system is equipped with an auto-greaser and protects the crusher’s dust-sensitive parts, leading to longer service life, fewer spare parts changes, and lower maintenance costs. All operations are fully automated.

Intelligent second-stage crushing

Optimizing the secondary step in the crushing process means more money for operators. Sandvik says its latest high-precision cone crusher for second stage crushing is more than the next generation of crushers. It is an intelligent, uncompromising piece of power built to produce more. The unit is said to offer up to a 25-percent greater reduction ratio while reducing recirculation by 50 percent with the same high-value product.

Inverted tramp relief system protects hydraulic cylinder rod

Superior Industries says the simple design of its Patriot Cone Crusher’s inverted tramp relief system ensures the hydraulic cylinder rod seal is not exposed during operation. This greatly reduces chances of contamination and failure. The tramp relief system has fewer accumulators to minimize maintenance and opportunity for failure. If an accumulator does fail, an internal relief valve provides instant relief. When mounted for portability, the crushing plant includes Vantage Automation and Level Assist for quick setup.

Anti-spin feature extends manganese life

The newest model in Telsmith’s line-up of T-Series crushers that were originally introduced in 2012 is the T500, which is designed to deliver maximum uptime availability while also minimizing maintenance costs. This 500-horsepower crusher contains a 14-inch maximum feed opening and is capable of processing between 314 and 854 tons per hour. Features, such as anti-spin and fewer cylinders than competitive crushers, are said to provide improved reliability for maximized processing.
