How a Jaw Crusher Works

A jaw crusher breaks rock by compressive force between two jaw plates. The eccentric shaft drives a reciprocating swing jaw that crushes material against a fixed jaw, releasing it downward through the adjustable discharge gap.

01

Feed

Raw rock or ore is top-fed into the V-shaped crushing chamber. Maximum lump size must not exceed 80% of the gape (feed opening width).

02

Compress

The eccentric shaft rotates, driving the swing jaw forward. Rock is trapped and crushed by compressive force against the fixed jaw plate.

03

Release

On the return stroke the swing jaw opens. Crushed material drops under gravity toward the narrower discharge end of the chamber.

04

Discharge

Product exits at the bottom at the size set by the CSS (Closed Side Setting). Wider CSS = higher capacity; narrower CSS = finer product.

* CSS = Closed Side Setting. Capacity figures are for medium-hard limestone at the middle CSS value. Granite and hard ores may reduce capacity by 20–30%.

Main Components

Understanding each component helps you order the right spares and perform targeted maintenance. All wear parts are stocked for same-week dispatch.

01

Frame

Heavy-duty welded or cast-steel frame. The fixed jaw plate is bolted directly to the front wall, forming one half of the crushing chamber.

02

Eccentric Shaft

Forged alloy-steel shaft transmits rotary motion from the motor to create the swing jaw's reciprocating movement, mounted in spherical roller bearings.

03

Movable (Swing) Jaw

Suspended from the eccentric shaft at the top. Moves in an elliptical arc — wider at the feed end, narrower at discharge — maximising nip angle and throughput.

04

Fixed Jaw

Stationary jaw plate bolted to the front frame. Works in tandem with the movable jaw to generate compressive crushing force against the rock.

05

Jaw Plates

High-manganese steel (Mn13–Mn18) with a corrugated profile to grip material. Reversible design doubles service life. No need to remove the jaw body to replace.

06

Toggle Plate

Acts as a safety fuse: breaks first if tramp metal enters, protecting the frame and shaft. Also transmits thrust to the swing jaw on the power stroke.

07

Tension Spring & Rod

Pulls the swing jaw back on the return stroke to open the discharge gap. Keeps the toggle plate seated and eliminates vibration bounce between cycles.

08

Flywheel

Twin cast-iron flywheels store kinetic energy to smooth the crushing cycle and reduce peak motor load by up to 30%.

Industry Applications

PE jaw crushers handle compressive strength up to 320 MPa — suitable for virtually all hard, medium-hard, and brittle materials.

Mining

Gold ore, copper ore, iron ore, manganese ore

Pre-crushes ROM ore to belt-conveyor feed size before secondary grinding mills.

Quarrying

Granite, basalt, andesite, diorite

Handles high-hardness rock (≤320 MPa) as the primary stage of aggregate plants.

Limestone & Cement

Limestone, dolomite, calcite

Medium-hard feed for cement raw material or downstream ball mills and kilns.

Construction Recycling

Demolished concrete, brick rubble, asphalt

Breaks down demolition waste to recyclable aggregate for road base.

Metallurgy

Slag, laterite nickel ore, chrome ore

Handles abrasive, irregular lump material with fast wedge-type CSS adjustment.

Road Construction

River pebble, sandstone, mixed aggregate

Produces road base and sub-base aggregate at an adjustable discharge size.

How to Select Your PE Model

Follow these four steps to narrow down the right model. When in doubt, our engineers confirm the best fit via WhatsApp within 24 hours.

01

Determine Maximum Feed Size

Measure the largest lump dimension of your ROM (run-of-mine) material. The feed opening width (gape) must be at least 1.25× the maximum lump. For example, 500 mm lumps → PE-750×1060 or larger.

02

Define Required Throughput

Set your target capacity in t/h. Choose a model whose rated capacity covers 120–130% of your target to buffer feed variability and allow for future expansion.

03

Check CSS Range vs. Required Output Size

The CSS (Closed Side Setting) is the minimum gap between jaw plates and controls your coarsest output. Smaller CSS = finer product but lower capacity. Confirm the model's CSS range covers your target.

04

PE vs. PEX — Which Series?

PE: tall chamber, up to 1,020 mm feed, CSS 20–350 mm — true primary crusher. PEX: short/wide chamber, feed ≤250 mm, CSS 18–90 mm — secondary or fine duty, no separate cone needed for small plants.

Not sure which model fits?

Tell us your raw material, max lump size, required t/h, and target output size. Our engineers will recommend the correct model within 24 hours.

Maintenance Schedule

Proper maintenance doubles jaw plate life and prevents catastrophic shaft failures. Follow this schedule to maximise uptime.

Every 8 Hours

  • Apply ¼ lb of grease per bearing (eccentric shaft + main shaft)
  • Check V-belt tension — max 15 mm deflection under 5 kgf
  • Inspect jaw plate ridges for cracks or heavy wear
  • Verify discharge chute is clear of build-up

Weekly

  • Measure CSS with a lead slug; adjust wedge if outside spec
  • Check toggle plate seating and tension spring pre-load
  • Inspect flywheel key and eccentric shaft end nuts for looseness
  • Record empty-run motor amperage (rising amps = wear indicator)

Monthly / As Needed

  • Flip or replace jaw plates when ridge loss exceeds 30%
  • Drain and refill bearing grease (replace every 3–6 months)
  • Inspect toggle plate for cracks; replace as matched pair
  • Check frame welds and liner bolts for fatigue or looseness

PE / PEX Jaw Crusher FAQ

Short answers to common procurement questions before requesting quotation.

How do I choose the right PE jaw crusher model?

Start with maximum feed size, then confirm throughput, target output, and CSS range. Keep 20-30% headroom to absorb feed variation and future expansion.

What is the difference between PE and PEX jaw crushers?

PE models are primary crushers with larger feed openings. PEX models are fine-jaw units for smaller feed and tighter discharge in secondary or fine duty.

Can PE jaw crushers process granite and hard rock?

Yes. PE jaw crushers are designed for hard and abrasive materials up to about 320 MPa compressive strength, including granite, basalt, and various ores.

What maintenance is most important on a jaw crusher?

Prioritize lubrication, CSS checks, and jaw plate wear monitoring. Consistent preventive maintenance reduces unplanned shutdowns and protects the shaft and frame.

PEX Series

Fine Jaw Crusher Specifications

Less commonly needed — only relevant when you require secondary or fine crushing down to 18 mm without a separate cone crusher. Feed ≤ 250 mm; short, wide chamber design.
