PE250x400 Jaw Crusher
I. Product Overview: Compact Size, Capable Primary Crushing
The PE250×400 is the entry-level model in the PE series of jaw crushers, widely used for primary crushing in the mining, construction materials, and metallurgical industries. Its operating principle mirrors that of larger jaw crushers: a motor drives an eccentric shaft, causing the swing jaw to reciprocate and compress the material. The material is progressively crushed within the chamber formed by the jaw plates until it is reduced to a size smaller than the discharge opening and released. While the reciprocating motion appears simple, it represents the most stable and clog-resistant crushing method for hard rock processing.
It features a compact structure (weighing approximately 2.8 tons) and offers flexible installation options, suitable for either stationary setups or integration with mobile chassis. As a low-tonnage member of the series, it complements models like the PE400×600 and PE600×900 to form a comprehensive capacity range—allowing small production lines to use appropriately sized crushers and avoiding the excessive investment of "using a sledgehammer to crack a nut."
II. Typical Application Scenarios: Five Key Operating Conditions
2.1 Primary Crushing for Small Mines and Quarries
For small-scale aggregate plants or marble/limestone mines with daily outputs of a few hundred tons, the PE250×400 serves as the primary crusher; when paired with secondary crushing equipment, it forms a complete production line. Compared to purchasing finished aggregates, establishing in-house crushing capabilities can directly cut the cost per ton by 40%–60%.
2.2 Primary Crushing Stage in Manufactured Sand Lines
Materials such as river pebbles, granite, and limestone require coarse crushing before sand making. The PE250×400 produces an output of 20–60 mm, perfectly meeting the feed requirements of sand-making machines (such as VSI or roll crushers) and enabling a low-cost sand-making pathway that utilizes "crushing instead of grinding" or a "crushing-grinding combination."
2.3 Support for Small-Scale Artisanal and Small-Scale Gold Mining (ASGM) Plants
ASGM operations worldwide frequently face the dilemma of having ore deposits but lacking crushing equipment. When combined with a wet ball mill and a gold grinding mill, the PE250×400 forms a classic small-scale processing circuit—"Jaw Crushing → Ball Milling → Beneficiation." Offering low investment costs and quick returns, this setup is a standard configuration for gold mining operations in Africa and Southeast Asia.
2.4 Recycling of Construction Waste and Old Road Materials
Construction waste often contains a mixture of rebar and concrete; the jaw crusher offers high tolerance for foreign objects and is unaffected by the presence of tramp iron. The PE250×400 can crush this material into recycled aggregate for backfilling or brick manufacturing, making it an economical choice for urban solid waste recycling projects.
2.5 Off-Grid/Power-Constrained Areas: Diesel Engine Drive Option
For mining areas with unstable power grids or no electricity at all, the PE250×400 can be fitted with a direct-drive diesel engine, eliminating reliance on the electrical grid. In scenarios such as regions with power rationing (e.g., South Africa) or remote African mines, this configuration ensures the production line remains operational despite power outages.

III. Core Specifications and Technical Advantages
3.1 Technical Specifications Table
| Parameter | Value |
| Model | PE250×400 |
| Feed Opening Size | 250×400 mm |
| Max. Feed Size | ≤210 mm |
| Discharge Opening Adjustment Range | 20–60 mm |
| Processing Capacity | 5–20 t/h |
| Eccentric Shaft Speed | 300 r/min |
| Motor Power | 15 kW (Diesel engine option available) |
| Total Machine Weight | Approx. 2.8 t |
| Applicable Compressive Strength | ≤320 MPa |
Note: The capacity figures in the table above are nominal values based on limestone (bulk density approx. 1.6 t/m³). When crushing hard rock such as granite or basalt, actual capacity is approximately 70%–80% of the nominal value; capacity decreases as material hardness increases or the required output size becomes finer. Please calculate requirements based on actual operating conditions rather than placing orders solely based on nominal values.
IV. Practical Case Studies and Return Analysis
4.1 Case Study 1: West African ASGM Gold Mine – "Jaw Crusher + Ball Mill" Combination
A small-scale gold mine in West Africa previously relied on manual hammering to crush ore, resulting in a daily processing capacity of less than 5 tons, uneven particle sizes, and low ball-milling efficiency. After introducing the PE250×400 model, ore is crushed to under 30mm by the jaw crusher before entering the ball mill; daily processing capacity increased to 80 tons (8 t/h × 10 h), and ball-milling efficiency improved by over 30%. The revenue gains resulting from the improved overall recovery rate of the processing plant far exceeded the initial investment in the equipment.
4.2 Case Study 2: Southeast Asia River Pebble Sand-Making Line
Local river pebbles, characterized by high compressive strength and high abrasiveness, are considered a "tough nut to crack" in the sand-making industry. The production line utilizes a three-stage configuration: "PE250×400 primary jaw crusher + sand-making machine + wheel-bucket sand washer." The jaw crusher first reduces 210mm river pebbles to under 40mm, and the sand-making machine further processes them into 0–5mm manufactured sand. The hourly output is 12–15 tons, with uniform particle size and controllable fines content, allowing the product to directly replace natural sand in concrete mixing plants.
4.3 Case Study 3: On-site Recycling of Construction Waste at a Mining Site
Demolition activities at a mining site generated large quantities of concrete blocks, and the cost of transporting them off-site was prohibitively high. A mobile PE250×400 small jaw crusher was deployed on-site to crush the material into 20–40mm recycled aggregate for use in road base layers and backfilling within the mining area. This saved approximately 30%–50% in transportation and procurement costs, and the equipment could be relocated to another site upon project completion, ensuring the asset did not sit idle.
V. Recommended Auxiliary Equipment
While the PE250×400 can discharge material as a standalone unit, a complete production line requires appropriate auxiliary equipment:
| Stage | Recommended Equipment | Description |

VI. FAQs
Q1: What is the actual hourly output of the PE250×400?
The nominal capacity is 5–20 t/h, but the actual output depends on three factors: material hardness, discharge particle size setting, and feeding continuity. When crushing medium-hard limestone with a 40mm discharge size, it can reach 15–20 t/h; when crushing granite with a 20mm discharge size, the output is approximately 8–12 t/h. When selecting a model, apply the practical rule of "reducing capacity by 20% for hard rock"; if necessary, request data from the manufacturer regarding similar operating conditions.
Q2: Can the PE250×400 crush hard materials like granite and river pebbles?
Yes. It handles materials with a compressive strength of up to 320 MPa; granite (typically 150–250 MPa), river pebbles, and basalt all fall within this range. When crushing hard materials, it is recommended to: optimize the feed opening, maintain continuous and uniform feeding, and use jaw plates with higher manganese content to extend their service life.
Q3: What is the approximate price of the PE250×400, and what does the configuration include?
The international market price for the bare machine is roughly in the range of several thousand US dollars, depending on the specific configuration—such as the drive type (electric motor or diesel engine), inclusion of a mobile chassis, jaw plate material, and the quantity of spare parts. It is recommended to provide the manufacturer with three key details—material type, target production capacity, and power supply conditions—to request a comprehensive quote that includes shipping and customs duties; this provides a more meaningful reference than the bare machine price alone.
