Types and Specifications of Jaw Crushers

Jaw Crushers: Core Primary Crushing Equipment for Mining, Construction, and Building Materials Industries，As the core primary crushing equipment in industries such as mining, construction, and building materials, the classification of jaw crusher models and specifications relies on core parameters including feed opening size, processing capacity, discharge opening adjustment range, equipment weight, and supporting motor power. Naming conventions for models vary slightly among different manufacturers (e.g., Dongmeng Heavy Industry Technology classifies its jaw crushers into multiple series). However, overall, jaw crushers can be categorized into the following types based on structural type, feed opening size, and application scenario. Below, Dongmeng Heavy Industry Technology Group introduces the general and common model specification system and classification explanations:

1. Classification by Structural Type: Core Difference Lies in the Movement Trajectory of the Movable Jaw

Jaw crushers are mainly divided into two major categories: Double Toggle Jaw Crushers and Single Toggle Jaw Crushers. The model systems of the two are independent, and they are suitable for different application scenarios.

1. Double Toggle Jaw Crushers (Traditional Type, Mostly Used for Large-Scale Primary Crushing)

• Structural Features: The movable jaw performs a simple arc swing. It has a deep crushing chamber, strong feeding capacity, and a large reduction ratio (generally 5-8). However, its movement speed is slow and production efficiency is relatively low. It is suitable for primary crushing of high-hardness and large-sized materials (such as granite, basalt, and iron ore).
• Common Models and Specifications (Based on Domestic General Models):

Domestic Model	Feed Opening Size (L×W, mm)	Max. Feed Size (mm)	Discharge Opening Adjustment Range (mm)	Processing Capacity (t/h)	Supporting Motor Power (kW)	Equipment Weight (t)
PE 600×900	600×900	500	60-160	50-160	55-75	28.5
PE 750×1060	750×1060	630	80-200	110-320	110	51
PE 900×1200	900×1200	750	100-220	220-500	160	85
PE 1200×1500	1200×1500	1000	150-300	400-800	220-250	145
PE 1500×1800	1500×1800	1200	200-350	600-1200	315	240

2. Single Toggle Jaw Crushers (High-Efficiency Type, Mainstream Selection)

• Structural Features: The movable jaw performs complex swing + translational motion. It has a shallow crushing chamber but high crushing efficiency (20%-30% higher than double toggle jaw crushers), low energy consumption, and a compact structure. It is suitable for primary/secondary crushing of medium-hardness materials (such as limestone, concrete blocks, and marble) and is also the mainstream configuration for mobile jaw crushers currently.

2. Classification by Feed Opening Size (Processing Capacity): From Small-Sized to Extra-Large-Sized

This is the most intuitive classification method in the industry, directly corresponding to the "processing scale" of the equipment, and is suitable for scenarios with different capacity requirements:

1. Small-Sized Jaw Crushers (Feed Opening < 400 mm, Processing Capacity < 50 t/h)

• Core Models: PE 150×250, PE 200×300, PEX 250×750, PE 300×400
• Application Scenarios: Small quarries, crushing of construction and decoration waste, laboratory crushing (such as ceramic tiles and small stones)
• Typical Parameters: The PE 200×300 has a feed opening of 200×300 mm, a discharge opening of 15-40 mm, a processing capacity of 5-15 t/h, and a motor power of 15 kW.

2. Medium-Sized Jaw Crushers (Feed Opening 400-900 mm, Processing Capacity 50-300 t/h)

• Core Models: PE 400×600, PE 500×750, PE 600×900, PE 750×1060
• Application Scenarios: Primary crushing in medium-sized mines, aggregate crushing in concrete mixing plants, highway construction (crushing limestone, sand and gravel)
• Typical Parameters: The PE 600×900 has a processing capacity of 50-160 t/h and is suitable for "100-200 t/h sand and gravel production lines".

3. Large-Sized Jaw Crushers (Feed Opening > 900 mm, Processing Capacity > 300 t/h)

• Core Models: PE 900×1200, PE 1200×1500, PE 1500×1800, PE 1600×2100
• Application Scenarios: Primary crushing in large metal mines (iron ore, copper ore), large quarries (granite, basalt), water conservancy projects (such as dam aggregate crushing)
• Typical Parameters: The PE 1200×1500 has a processing capacity of 400-800 t/h and needs to be equipped with a heavy-duty vibrating feeder and conveyor belt.

4. Extra-Large-Sized Jaw Crushers (Feed Opening > 1800 mm, Processing Capacity > 1000 t/h)

• Core Models: PE 1800×2100, PE 2000×2200 (mostly customized models; international brands such as the Metso GMP series)
• Application Scenarios: Extra-large open-pit mines (such as coal and metal mines), requiring matching with large excavators (bucket capacity ＞ 10 m³) for feeding
• Typical Parameters: The PE 1800×2100 has a maximum feed size of 1500 mm, a processing capacity of 800-1500 t/h, a motor power of 400 kW, and an equipment weight of over 300 t.

DC160	1300×1600	1000	581-1204	220	250	150-300	75

4. Key Selection Factors: Core Dimensions for Matching Models to Requirements

1. Material Characteristics: For high-hardness materials (such as basalt), select large-sized double toggle models (PE series); for medium-hardness materials (such as limestone), select single toggle models (PE/PEX series).
2. Capacity Requirements: For a processing capacity of 300-500 t/h, select PE 900×1200 (double toggle) or PE 1000×1200 (single toggle); for 50-100 t/h, select PE 500×750.
3. Feed Size: The maximum feed lump size must be ＜ 80% of the feed opening width (e.g., for the PE 600×900 feed opening, the maximum feed size ≤ 500 mm).
4. Installation Scenario: For mobile crushing, select small/medium-sized single toggle models (such as QJ341, PE 400×600); for fixed production lines, select large/medium-sized models as needed.
