What is diesel jaw crusher?
Diesel jaw crusher is a crushing equipment designed for powerless or mobile operation scenarios with diesel engine as the power source. The main models include PE-150×250 and PE-250×400. This equipment combines the core structure of the jaw crusher with the diesel engine drive system, and also can be equipped with a small vibrating screen to form an efficient crushing and screening production line, which can meet the production demand of 1-20 tons/hour. Its compact design and strong adaptability are particularly suitable for mining, construction waste treatment and infrastructure construction in Africa (Kenya, Uganda, Cameroon, Tanzania) and South America (Guatemala, Peru, Mexico, Colombia) and other regions.

Working principle of 1-20tph diesel crusher:
1.Power Drive and Transmission System
The power core of the diesel jaw crusher is a high-performance diesel engine, which drives the eccentric shaft to rotate through a belt drive. The periodic rotation of the eccentric shaft drives the movable jaw plate to reciprocate, forming a periodic opening and closing action with the fixed jaw plate. When the movable jaw plate is close to the fixed jaw plate, the material is squeezed, split and bent between the two jaw plates; when the movable jaw plate is far away, the crushed material is discharged from the discharge port under the action of gravity.
2.Crushing chamber and discharge adjustment
The crushing chamber adopts a deep chamber design (such as PE-250×400 type), and the dead zone-free structure can improve the feeding efficiency and crushing ratio. The size of the discharge port is adjusted by adjusting the screw. Users can control the particle size of the finished product according to their needs (usually 10-40mm). After matching with a vibrating screen, it can be further graded to achieve multi-specification material output.
3.Safety and stability
The equipment is equipped with a toggle plate safety device. When unbreakable objects enter the chamber, the toggle plate automatically breaks to protect the core components; the reset spring and pull rod system ensure the stable reset of the movable jaw plate and ensure the reliability of continuous operation.
Core advantages
Flexibility and adaptability
No dependence on electricity: Diesel drive makes it suitable for remote mining areas or areas with unstable electricity, such as sub-Saharan Africa and the Andes Mountains in South America.
Easy to move: can be mounted on a trailer or simple chassis, quickly transferred to different operating points, and meet the needs of decentralized mining or temporary projects.
High efficiency and energy saving
Optimized cavity design and high manganese steel jaw plate (compressive strength of 320MPa) reduce wear, and the energy consumption of a single machine is 15%-30% lower than that of traditional models.
Diesel engines have high fuel efficiency, combined with energy-saving transmission systems, and the comprehensive operating cost is significantly lower than similar electric equipment.
Versatility and durability
It can crush a variety of ores and construction waste such as granite, basalt, limestone, etc., with a maximum feed size of 210mm (PE-250×400 type).
Heavy eccentric shaft and integral cast steel movable jaw structure enhance the bearing capacity of the equipment and extend the service life to more than 10 years.

IV. Application market analysis
African market
Kenya and Tanzania: Relying on the construction of the East African railway network and the export of minerals from the Port of Mombasa, there is a strong demand for small and medium-sized crushing equipment. Diesel models have become the mainstream choice because they are suitable for mining areas without power grids46.
Cameroon and Uganda: Gold and bauxite resources are abundant, but infrastructure is weak. Diesel jaw crushers have become the first choice for small and medium-sized mining companies due to their mobility and high cost-effectiveness.
South American Market
Peru and Colombia: Copper and gold mining is active, and most mining areas are located in the Andes Mountains. Diesel equipment is popular because it can adapt to high altitudes and complex terrain.
Mexico and Guatemala: The demand for construction waste recycling and road construction is growing. Diesel jaw crushers can be combined with vibrating screens to achieve on-site crushing and screening, reducing transportation costs.
Industry driving factors
Mineral resource development: The global mining recovery promotes the purchase of small and medium-sized mining equipment, and diesel models meet the needs of low cost and rapid production.
Environmental policy adaptation: Some developing countries have relatively loose environmental standards, and diesel equipment is still competitive in areas with low emission control requirements.
V. Typical configuration and cases
Take PE-250×400 as an example:
Diesel engine power: 30-40 horsepower, suitable for Changchai, Weichai and other brands;
Feed particle size: ≤210mm;
Discharge adjustment range: 20-60mm;
Matching vibrating screen: 2-layer screen, screening efficiency ≥90%, finished products are divided into three levels: 0-10mm, 10-30mm and above 30mm.
Case: In a gold mine project in Kenya, the combination of PE-250×400 diesel jaw crusher and vibrating screen achieves an average daily processing capacity of 200 tons. The ore is crushed to less than 15mm and directly enters the ball mill, saving 30% energy consumption compared with traditional processes.
VI. Future trends and suggestions
Technology upgrade: Introduce hydraulic adjustment and intelligent monitoring systems to improve operational convenience and fault warning capabilities.
Localized services: Set up spare parts warehouses and technical service points in key markets (such as Tanzania and Peru) to shorten after-sales response time.
Environmental adaptation: Develop low-emission diesel engine models to meet the gradually tightened environmental regulations in some countries.
Summary: Diesel jaw crushers occupy an important position in emerging markets in Africa and South America due to their power autonomy, high adaptability and economy. Through continuous performance optimization and localized services, the equipment is expected to further consolidate its core position in resource development and infrastructure.
