Types of Jaw Crushers: Single Toggle vs. Double Toggle Explained
The main difference between a single toggle and a double toggle jaw crusher is how the moving jaw is supported and driven. A single toggle design uses a top-mounted eccentric shaft and one toggle plate, while a double toggle design uses a separate jaw pivot, an eccentric drive and two toggle plates.
For buyers, the practical question is not which design is universally better. It is which machine can process your material at the required discharge setting, with acceptable wear, installation requirements and operating costs.
Single Toggle vs. Double Toggle Jaw Crusher: Quick Comparison
| Comparison | Single Toggle Jaw Crusher | Double Toggle Jaw Crusher |
|---|---|---|
| Drive arrangement | Top-mounted eccentric shaft working with one toggle plate. | Separate upper jaw pivot and eccentric drive working through two toggle plates. |
| Moving jaw action | Compound motion, commonly described as elliptical, combines compression with rubbing. | Jaw movement produces an almost purely compressive action. |
| Throughput tendency | The feeding action can support higher throughput than a comparable-size double toggle machine. | Generally lower throughput in that comparable-size comparison, not necessarily lower capacity across all models. |
| Jaw plate wear | Rubbing action can increase wear on the crushing surfaces. | Reduced rubbing can help limit jaw surface wear on highly abrasive material. |
| Structure and installed cost | Generally simpler and lighter, with lower installed cost in the traditional design comparison. | More complex mechanism; actual installed cost requires a project-specific quotation. |
Use this table to shortlist options, not to calculate a guaranteed performance difference. Request capacity and wear estimates under the same feed conditions and required discharge setting before comparing quotations.
How Does a Single Toggle Jaw Crusher Work?
In a single toggle jaw crusher, the moving jaw is supported directly on the eccentric shaft, with its lower section supported by a toggle plate against the frame. Rotation of the eccentric creates a compound jaw movement that compresses the rock and helps feed it downward through the chamber, as described in the single toggle mechanism study.
The same movement creates a trade-off: the rubbing component assists material movement but can also increase jaw plate wear. The research describes the single toggle design as simpler and lighter than the traditional double toggle arrangement, rather than presenting it as superior in every application.
A double toggle jaw crusher separates the moving jaw's upper pivot from the eccentric drive. The eccentric operates a pitman and two toggle plates, transmitting force to swing the jaw toward the fixed jaw, as outlined in Metso's explanation of jaw crusher types.
Its crushing action is almost purely compressive, with less rubbing at the jaw surfaces. This characteristic makes the traditional double toggle design relevant to very hard, highly abrasive materials, according to the published mechanism research.
If a supplier recommends a double toggle jaw crusher, ask what measurable advantage it offers on your material. Request supporting wear records, throughput estimates and a complete installation scope instead of accepting the mechanism name as sufficient justification.
Which Jaw Crusher Is Better for Hard Rock?
Do not use rock hardness alone to decide between single toggle and double toggle jaw crushers. The research links double toggle suitability to its low-rubbing action, while HAMAC also lists hard and abrasive rock applications for its jaw crusher products. Mechanism research; HAMAC European Tech. Jaw Crusher applications.
For a granite, basalt or ore project, provide the supplier with available compressive strength data in MPa, abrasiveness test results, maximum lump size in mm, feed grading and moisture conditions. Ask the supplier to assess the specific crusher design against these inputs rather than selecting only by the material name.
Treat "single toggle," "double toggle," "PE," "PEX" and "European type" as different kinds of descriptions, not interchangeable classifications. Confirm the offered machine's mechanism from its technical documentation; HAMAC's PE product page, for example, distinguishes PE primary-crushing models from PEX secondary-crushing models.
Jaw Crusher Specifications: What Should Buyers Compare?
Start with maximum feed size, required capacity and the feed size accepted by the next crushing stage. These are also the selection factors identified on the HAMAC PE jaw crusher product page.
The following figures are published model specifications, not a controlled single toggle versus double toggle performance test. Each model name links to HAMAC's source table.
| HAMAC Model | Feed Opening | Maximum Feed Size | Listed Output Range | Listed Capacity | Motor Power | Weight |
|---|---|---|---|---|---|---|
| PE500×750 | 500×750 mm | 425 mm | 50–100 mm | 40–110 t/h | 55 kW | 11.7 t |
| PE600×900 | 600×900 mm | 500 mm | 65–180 mm | 80–180 t/h | 55–75 kW | 16.1 t |
| PE750×1060 | 750×1060 mm | 630 mm | 80–180 mm | 110–320 t/h | 90–110 kW | 30.1 t |
Keep the source table's terminology: it labels these values "Output Range," not explicitly CSS or a guaranteed finished-product grading. For example, PE600×900 is listed at 80–180 t/h, but the page does not provide a capacity curve tying each throughput value to a particular setting and feed condition. Check the original technical table.
If your project requires 150 t/h, ask HAMAC to confirm expected throughput at your specified discharge setting and material conditions. Do not assume that falling within a catalogue capacity range guarantees the required production rate.
For installation planning, the HAMAC 6CX106 technical table lists a 1060×700 mm feed opening, 110 kW motor, 280 rpm speed, 19,000 kg total weight and 7,800 kg maximum single-part weight. These figures provide useful starting inputs for checking electrical requirements, transport and lifting arrangements. View European Tech. jaw crusher specifications.
Compare Wear Cost per Tonne, Not Just Jaw Plate Price
Ask each supplier to report wear life in tonnes processed, together with material type, operating setting and the jaw plate replacement criteria. This makes the comparison more useful than a plate price or service-life estimate without operating conditions.
For a simple comparison, calculate jaw plate purchase cost per tonne as: replacement plate purchase cost divided by tonnes processed before replacement. As a hypothetical example, a USD 1,200 set lasting 12,000 tonnes gives a plate purchase cost of USD 0.10 per tonne.
That example is not a HAMAC quotation or wear-life guarantee. Add freight, replacement labour and downtime separately when comparing total ownership cost, and request comparable operating records for the candidate machines.
Frequently Asked Questions About Jaw Crusher Types
Does a single toggle jaw crusher always have higher capacity?
No universal capacity advantage should be assumed across different models. Metso describes better capacity for the single toggle design compared with a double toggle jaw crusher of similar size; use that as a general design comparison, then request application-specific performance data. Read the comparison conditions.
Does a double toggle jaw crusher always cost less to operate?
Reduced rubbing can help limit jaw surface wear, but that alone does not establish total operating cost. Compare the wear advantage described in the mechanism research against each quotation's installation, energy, maintenance and downtime assumptions.
Does double toggle mean two crushing chambers?
No. The term describes the two toggle plates in the drive mechanism, not two separate crushing chambers.
What information is needed for a jaw crusher quotation?
Provide the rock or ore type, maximum feed size in mm, target capacity in t/h, required downstream feed size, daily operating hours, site location and available electrical supply. Include a material test report and site layout if available.
