What Is a Diesel Powered Mobile Hammer Crusher?
A diesel powered mobile hammer crusher is a self-contained crushing unit that mounts a hammer crusher onto a wheeled or tracked chassis, driven entirely by a diesel engine. It performs medium to fine crushing of moderately hard, brittle materials—typically sitting between primary crushing and final screening. Common uses include on-site aggregate production, road base material preparation, and demolition waste recycling in areas without power lines.
These crushers handle feed sizes up to 250 mm and produce outputs ranging from 10 to 80 mm (adjustable by changing grate bar spacing). Capacity varies from 30 to 120 t/h depending on rotor diameter (800–1250 mm) and engine power (75–160 kW). Key components include the diesel engine, high-speed rotor with replaceable hammers, reinforced crushing chamber with breaker plates, adjustable grate bar assembly, mobile chassis (tyre or track), and a control panel for engine and choke monitoring.
How Does a Diesel Powered Mobile Hammer Crusher Work?
A diesel powered mobile hammer crusher transmits engine power through a clutch and belt drive to a high-speed rotor rotating at 750–1100 rpm. Hammers attached to the rotor strike incoming material repeatedly inside the crushing chamber. Unlike jaw crushers that rely on compression, this machine uses high-velocity impact to fracture brittle materials instantly—making it significantly more effective for medium-hard ores, coal, and demolition waste.
The typical process: material (≤250 mm) is fed into the hopper → evenly enters the crushing chamber → rotating hammers strike at tip speeds of 25–40 m/s → crushed material circulates until small enough to pass through bottom grate bars (adjustable 10–80 mm) → discharged via conveyor or chute.
Main efficiency factors: hammer tip speed is most critical (below 25 m/s reduces fracture); moisture above 12–15% tends to clog grate openings; grate bar spacing and open area (30–50% standard) control output size and throughput. Regular hammer inspection every 300–600 operating hours maintains performance.

Project Case
Diesel Mobile Hammer Crusher Case Study: Road Base Production in Mozambique
A quarry in Cabo Delgado, Mozambique, required a reliable crushing solution for road base production in an off-grid environment. Based on the limestone characteristics and production target, Zhongyi recommended a ZY-DMHC-1000 diesel mobile hammer crusher with an integrated feeder and screening system. Manufactured by Zhongyi, the unit was configured with a 110 kW diesel engine to ensure stable operation without grid power. After installation and operator training, the crusher achieved an average output of 53 t/h, meeting the customer’s 50 t/h requirement. The mobile unit was relocated three times during the project, helping the quarry improve flexibility and reduce transportation costs while maintaining continuous aggregate production.

FAQs
What is a diesel powered mobile hammer crusher used for?
A diesel powered mobile hammer crusher is designed for on-site crushing of medium-hard and brittle materials such as limestone, coal, gypsum, and construction waste. Equipped with a diesel engine and mobile chassis, it operates independently without grid power, making it suitable for remote mines, quarries, and temporary crushing projects.
What materials can a diesel mobile hammer crusher process?
Diesel mobile hammer crushers can process materials including limestone, coal, gypsum, concrete, bricks, and other medium-hard rocks. The suitable application depends on material hardness, moisture content, feed size, and required output. Proper configuration helps improve crushing efficiency and reduce wear during continuous operation.
What feed size and output can I expect from a diesel mobile hammer crusher?
The maximum feed size is typically 150–300 mm, depending on rotor diameter and crusher configuration. Production capacity usually ranges from 30–120 t/h, while the final discharge size can be adjusted through grate spacing to meet different aggregate and processing requirements.
Is a diesel mobile hammer crusher suitable for wet materials?
Standard hammer crushers perform best with dry or low-moisture materials. For higher moisture applications, a grizzly-type discharge or customized configuration can help reduce material blockage and improve feeding stability. Material properties should be evaluated before selecting the suitable discharge design.
How is a diesel mobile hammer crusher different from an electric stationary crusher?
A diesel mobile hammer crusher does not require external power infrastructure and can be relocated between working areas, making it suitable for remote or short-term projects. Electric stationary crushers usually offer lower operating costs but require permanent installation, foundations, and stable power supply.
What factors affect diesel mobile hammer crusher price?
The price depends on crusher model, rotor size, diesel engine configuration, chassis type, and optional equipment such as feeders or screening systems. Different material conditions and production requirements also affect the final configuration. Zhongyi provides customized quotations based on specific project needs.
