Get your crush on with cones and jaws
Here’s a selection of cone and jaw crushers that are designed to handle some of the toughest crushing jobs.

Cone crushers offer producers high production and cost-efficient performance.
FLSmidth Pekin, LLC (formerly FLSmidth Excel LLC) says its Raptor XL600 cone crusher has a maximum throughput capacity that approaches 1,000 tons per hour. The cone has a 600-horsepower motor, large 60-inch crushing head, and handles feed sizes up to 14 inches. It can replace crushers with a 59-inch head diameter or larger without major modifications to foundations or feed arrangements.
The Kodiak Plus series of cone crushers is engineered to save time and money by reducing downtime and maintenance, according to KPI-JCI, an Astec company. The company says its precision-designed roller bearings generate high efficiencies and reduce operating temperatures while allowing a high tolerance to climate and temperature fluctuations.
Terex Cedarapids says its quick-adjust, 200-horsepower RC45 III ElJay Rollercone features a hydraulic thread adjustment system that makes setting changes quick and easy. The manganese of the cone rotates for uniform wear, which results in less maintenance. Its advanced crushing chamber technology is said to yield a high percentage of sized product on the first pass and a highly cubical product.
Telsmith Inc., an Astec Industries company, offers its model SBS cone crusher in five sizes ranging from 200 to 600 horsepower. The company says the cones are specifically built to deliver consistent sizing and reliable production in hard rock, secondary, and tertiary applications. The crusher features hydraulic anti-spin and remote Dynamic Adjust systems, making it fully automation enabled.
Jaw crushers offer interchangeable die, durable construction, and aggressive crushing.
Trio Engineered Products offers 14 jaw crusher models ranging from 10 by 30 inches to 60 by 80 inches with capacities exceeding 1,200 tons per hour. Features include oversized bearings, a drop-forged heat-treated eccentric shaft, and a cast pitman. Most models have hydraulically adjusted wedges for easy adjustment of the closed-side settings. All models incorporate a fixed jaw die with a wraparound design.
The Vanguard Plus series of jaw crushers from KPI-JCI, an Astec company, boasts production capacities as high as 816 tons per hour. The crushers feature a forged 1½-inch eccentric shaft to increase stroke productivity and toggle seats with alignment for maximum crushing action. Self-aligning spherical roller bearings offer additional strength and long-term service.
Metso says its new Nordberg C116 jaw crusher has a 45- by 32-inch opening and can be fed with rock up to 28 inches in size. The jaw features special steel castings, an alloyed oversized main shaft, premium quality bearings, a pin and bolt design for higher frame strength, a fast-setting adjustment with proven wedge system, and an integral motor mount.
Eagle Crusher says the crusher nip angle in its 3242 jaw plant enables the highest crushing efficiency. The hydraulically adjustable crusher setting can be adjusted from 102 millimeters to 204 millimeters. The heavy-duty feed hopper loads from either the sides or the back.
The JS Series jaw crushers from Terex Cedarapids features heavy-duty, deep rib jaw dies for aggressive crushing capability. The quick-change jaw die system and quick-adjust hydraulic shim system allow more uptime and quick, tool-less jaw setting adjustments. The jaw die wedges are accessible from the sides and are easily removed.
The Iron Giant jaw crusher from Telsmith Inc., an Astec company, ranges in size from 36 inches by 48 inches up to 50 inches by 60 inches. The crusher features a tall, high-volume crushing chamber with shallow nip angles and extra wear liners behind the jaw dies and throughout the toggle adjustment area.
Portable jaws and cones make it possible to move crushing operations from one place to another, quickly and affordably.
The 26- by 42-inch Generation II track jaw from Construction Equipment Co. boasts an all new slab side frame, conveyor, power, and hydraulic system for processing virgin material up to 60,000 pounds of compressive strength. The track system is built with heavy-duty components, achieving low ground pressure. The remote makes one-man feed and operation possible.
Sandvik says its QJ340 track-mounted mobile jaw crusher ensures durability and reliability through its reverse crushing action capability for relieving blockages and its automatic jaw lubrication system. The crusher offers on-the-job versatility through options that allow it to be modified to match the precise demands of any specific application.
The Mobicat MC 120 Z track-mounted jaw crusher from Kleemann, a Wirtgen America company, is driven by a 215-horsepower direct electric motor, which provides high-capacity crushing with efficient fuel usage. The jaw features a two-deck, fully independent pre-screen that can be fitted with punch sheet, grizzly, and wire mesh, and a lined, heavy-duty vibrating feeder below the crusher.
If a new crusher isn’t in the budget, remanufactured cone crushers are an option.
JW Jones Co. says it refurbishes all makes and models of portable and stationary cone crushers to perform like new. Each cone crusher is completely taken apart, evaluated, remanufactured, and then sold at up to 50 percent less cost than a new one. Stationary and portable cone crushers are available in size ranges from 2 feet up to 7 feet for production requirements up to 1,500 tons per hour.
