The PE250x400 Jaw Crusher stands as one of the most reliable and highly sought-after configurations in the global mineral crushing sector. Engineered as a single-toggle primary crushing unit, it features a feed opening size of 250 mm by 400 mm. Developed to process materials with a maximum feed size of 210 mm, this machine is optimized for reducing hard ores, granites, limestones, construction rubble, and slag.
Its operational paradigm centers on the eccentric movements of a heavy swing jaw driven by a forged eccentric shaft, which forces the target media against a fixed high-manganese tooth plate. This compressive mechanism generates substantial force, enabling high volume reduction ratios with minimal maintenance costs. In many installations, it acts as the cornerstone unit for small-to-medium enterprise (SME) mining plants, and as an essential preliminary size-reduction stage in laboratory sampling systems or aggregate manufacturing operations.
| Technical Parameter | Specification Value | Engineering Implications |
|---|---|---|
| Feed Opening (W x L) | 250 mm × 400 mm | Determines maximum initial input material dimension (~210 mm) |
| Discharge Setting Range (CSS) | 20 mm – 60 mm | Enables adjustable output sizing based on downstream process requirements |
| Processing Capacity | 5 – 20 Tons per Hour (t/h) | Scalable output optimized for small-scale plants and lab arrays |
| Main Motor Power | 15 kW (Electric) / 20–22 HP (Diesel equivalent) | Optimized power-to-torque conversion curves for hard rock crushing |
| Eccentric Shaft Speed | 310 revolutions per minute (rpm) | Ensures high-frequency crushing action for optimized product throughput |
| Total Dynamic Weight | Approx. 2.8 – 3.2 Metric Tons (Config-dependent) | Ideal for mobile, skid-mounted, and trailered field deployments |
Currently, the global demand for infrastructure construction, mineral beneficiation, and sand-making plants has surged. Within this macro-economic context, the PE250x400 model occupies a highly strategic segment of the international machinery market.
Small-scale alluvial and hard rock mining operations throughout the developing economies of Sub-Saharan Africa, South America, and Southeast Asia rely on the PE250x400 to break down gold-bearing quartz, iron ores, and copper vein matrixes before primary grinding stages (such as wet pan mills or ball mills). Because many of these operations are located in remote regions with limited access to centralized electrical grids, there is high demand for diesel-engine configurations, which are built and supplied by specialized Chinese manufacturing hubs like Zhengzhou in Henan Province.
From a commercial procurement standpoint, sourcing direct from wholesale manufacturers in China provides distributors with several advantages:
The versatility of the PE250x400 jaw crusher enables it to adapt to diverse local settings. Below are several typical case studies of this equipment in active industrial setups:
Commonly used in regions like Zambia and Sudan. The unit operates in tandem with gravity separation machines (shaking tables, wet pan mills) to reduce gold quartz ores down to less than 20mm feed, maximizing downstream gold recovery efficiency.
Popular in remote areas of Papua New Guinea and Tanzania. Mounts on a trailer with an integrated diesel engine and vibratory screen, enabling operators to crush granite on-site for immediate roadbase and concrete aggregate production.
Deployed in global testing laboratories and metallurgical research institutions to reduce bulk samples of hard rock, mineral ore, or construction waste to ensure consistent composite analysis feeds.
The mining machinery sector is shifting away from simple, heavy cast-iron structures toward smart, efficient, and eco-friendly systems. This evolution impacts the PE250x400 in several ways:

Deep dive into the operational mechanics of our primary crushing equipment
Impact crusher is a kind of secondary crushing equipment which uses impact power to crush materials. Impact crusher is characterized by easy maintenance, high reduction ratios and high efficiency to produce precisely cubic shape products. It is designed with three crushing chambers, seamlessly connected rotor, wear-resistant blow bar and installation of insert type. Moreover, it has tooth type liner, gradient designed bearing seat, frame with several openings and screws or hydraulic start-up devices. Impact crushers can be used in all different stages of size reduction from primary crushing to the last step of the crushing process.
