Notes: Capacity figures are based on feed with a loose bulk density of 1.6 t/m³ entering the crushing chamber freely. Values represent instantaneous maximum throughput and vary with material properties, feeding method, moisture and clay content. CSS is measured from the bottom of one jaw die tooth tip to the top of the opposite one. Contact our engineers for CSS-by-CSS capacity tables for your specific material.

A jaw crusher is a primary crushing machine. It takes large run-of-mine or blasted rock and breaks it down to a size that conveyors and secondary crushers can handle. Typical duties include quarry aggregate production, ore crushing ahead of grinding, and recycling of concrete and demolition material.
A motor drives the eccentric shaft through a belt and pulley, and the shaft moves the swing jaw toward and away from the fixed jaw in a repeated cycle. Rock entering the V-shaped chamber is squeezed and broken on the closing stroke, then falls lower on the opening stroke. Broken material exits through the discharge opening at the bottom, and the cycle repeats continuously.
The CJ series crushes rock and ore with compressive strength up to three hundred and twenty megapascals. That covers granite, basalt, river pebble, limestone, iron ore, copper ore and most quarry and mine feeds. Very wet or sticky material is poorly suited to jaw crushing and usually calls for different equipment upstream.
Start with three inputs: your largest feed lump, your required product size, and your target tonnage. The largest lump should stay within roughly eighty percent of the feed opening width. Required product size sets the closed side setting, and target tonnage checked against the capacity table at that setting identifies the model. Size with headroom so the crusher runs comfortably below its maximum.
A single toggle jaw crusher drives the swing jaw directly from the eccentric shaft, giving an elliptical jaw motion, higher speed and higher capacity. A double toggle design works through two toggle plates and produces a more purely vertical jaw motion, which suits extremely hard and abrasive feeds. The CJ series is a single toggle design, the mainstream choice for modern primary stations.
A jaw crusher handles primary crushing: large feed, coarse output, simple and robust. A cone crusher handles secondary or tertiary crushing, taking jaw crusher product and reducing it further with better particle shape. Most crushing plants use both in sequence, with screens between the stages.
Jaw die life depends on the abrasiveness of the feed. In limestone a set commonly lasts many months, while abrasive granite or basalt shortens life considerably. You can extend useful life by flipping the dies end-for-end partway through wear, and by matching the manganese steel grade and tooth profile to your material.
Support covers installation guidance, commissioning, operator training, technical response and spare parts supply for the life of the machine. Wear parts are factory-original, supplied by the manufacturer that built the crusher, and common liner and bearing specifications are held available so routine maintenance never waits on long-lead shipments.
Most buying mistakes with a jaw crusher trace back to sizing and material matching more often than to the machine itself. The notes below reflect how experienced plant designers select and run a primary jaw crusher, and they apply to any jaw crusher for sale on the market.
A jaw crusher is a compression-type primary crusher — the most widely used stone crusher in quarrying and mining. A fixed jaw die and a moving swing jaw form a V-shaped chamber. The eccentric shaft drives the swing jaw in a reciprocating path: rock is squeezed until it fractures on the closing stroke, then moves down the chamber on the opening stroke. The toggle plate doubles as a mechanical fuse — if tramp iron enters, the toggle fails first and protects the shaft, bearings and frame. Output size is controlled by the closed side setting, the smallest gap between the two dies at the bottom of the chamber.
Sizing comes down to three rules applied in order. First, feed size: the largest lump should not exceed about 80% of the feed opening width, or it bridges across the chamber and stalls production. Second, product size: work back from the closed side setting and check capacity at your real CSS instead of the model maximum. Third, tonnage: select so that normal demand sits around 60-70% of rated capacity, leaving headroom for peaks, harder zones and worn liners.
Two further checks complete the selection. Reduction ratio across a jaw crusher typically runs at 6:1 and reaches 8:1 at most — if your overall reduction target is larger, plan a secondary stage. And if your feed carries significant fines, a vibrating screen ahead of the crusher to scalp them out raises total capacity and improves liner wear. Buyers comparing older PE series machines with modern European-type designs should also weigh frame construction and adjustment systems, where current designs such as the CJ series differ most from the older generation.
Primary crusher selection usually means comparing the jaw crusher with a cone crusher, a gyratory crusher and an impact crusher. The table below summarizes where each machine fits.
| JAW CRUSHER | CONE CRUSHER | GYRATORY CRUSHER | IMPACT CRUSHER | |
|---|---|---|---|---|
| Typical stage | Primary | Secondary / tertiary | Primary, very high tonnage | Primary / secondary, soft to medium rock |
| Max feed size | Up to ~1,200 mm and above | Takes jaw crusher product | Largest of the four | Medium |
| Product size | Coarse, ~50-300 mm | Fine, ~6-50 mm, good shape | Coarse | Fine with excellent cubic shape |
| Operation | Simple, tolerates intermittent feed | Needs controlled choke feed | Continuous, suited above ~1,000 t/h | Sensitive to hard, abrasive feed |
| Watch out for | Limited reduction ratio per pass | Cannot take primary-size feed | High foundation and installation cost | Rapid wear on abrasive material |
The practical reading: for most quarries and mines a jaw crusher is the default primary machine. A gyratory earns its higher installation cost only at very large, continuous tonnages. Cone and impact crushers work downstream — the cone for hard rock reduction and shaping, the impact for softer, less abrasive material where particle shape is the priority.
Jaw dies are the main wear cost of a jaw crusher, and managing them well is the easiest way to cut cost per ton. Tooth profile comes first: aggressive profiles grip slabby feed and boost throughput on medium-hard rock, while broader profiles last longer on abrasive material. Manganese grade is the second lever — higher grades such as Mn18Cr2 hold up better where abrasion dominates over impact. CJ series jaw dies are symmetrical, so when the lower half is worn you flip the die end-for-end and run the fresh edge; flipping typically extends useful life by a fifth to two fifths per set.
As a primary rock crusher, the CJ series handles rock and ore with compressive strength up to 320 MPa: granite, basalt, river pebble, limestone, dolomite, iron ore, copper ore, gold ore and construction and demolition waste. In ore processing, the jaw crusher prepares feed for grinding and typically pairs with a ball mill circuit. For soft, sticky or coal-type feeds a roller crusher may be the better tool, and very wet, clay-rich material calls for washing and screening upstream. Hardness alone does not determine wear — silica content and abrasiveness drive liner consumption, so share a material analysis when requesting a selection.
