What is a Diesel Jaw Crusher?
A diesel jaw crusher is a primary jaw crusher driven by a diesel engine rather than an electric motor, used for coarse reduction of rock and ore where grid power is absent or unreliable. The machine reduces feed below 600 mm to a discharge between 10 and 100 mm in a single pass.
Standard models cover feed openings from 150×250 mm up to 1200×1500 mm, with throughput from 1 to 250 t/h and engines from 8 to 280 hp. Output is governed by feed gradation, jaw plate wear, closed-side setting (CSS), and engine rpm — most operators run between 80% and 90% of rated engine load to balance fuel burn and capacity.
Main components:
- Diesel Engine — Drives the eccentric shaft via V-belts; common brands are Cummins, Perkins, Weichai, and Kubota.
- Crushing Chamber — Deep cavity with manganese-steel jaw plates (11–14% Mn) for impact-abrasion resistance.
- Eccentric Shaft and Toggle — Convert engine rotation into the jaw’s oscillation cycle, typically at 250–330 rpm.
- Hydraulic CSS Adjuster — Sets discharge size between 10 and 100 mm without manual shimming.
How a Diesel Jaw Crusher Works ?
A diesel jaw crusher uses a diesel engine to drive the flywheel and eccentric shaft through a belt transmission system. The rotating eccentric shaft moves the movable jaw plate against the fixed jaw plate, creating compression force to crush large rocks into smaller sizes. Unlike electric jaw crushers, diesel models operate independently without grid power, making them suitable for remote mining, quarrying, and construction sites.
Typical Crushing Process
Crusher performance depends on material hardness, feed size, engine power, and CSS settings. Proper configuration helps maintain stable output, reduce fuel consumption, and extend wear part service life.
Diesel Jaw Crusher Types — Mobile, Skid-Mounted & Trailer-Pulled
Diesel jaw crushers are classified by chassis configuration, which dictates transport method and setup time. Zhongyi supplies and customizes all three types based on site mobility needs.
| Type | Chassis | Feed Size | Capacity | Setup Time | Best For |
| Trailer-Pulled | Towed trailer | ≤500 mm | 5–50 t/h | 2–4 hours | Small quarries, contractors |
| Skid-Mounted | Steel skid base | ≤800 mm | 30–100 t/h | 1–2 days | Semi-fixed installations |
| Self-Propelled Mobile | Track or wheel | ≤900 mm | 50–250 t/h | <1 hour | Large mobile operations |
These are typical reference ranges. Actual values depend on model and material.
Diesel Engine Options for Off-Grid Jaw Crushers
The diesel engine directly affects crusher performance, fuel efficiency, maintenance requirements, and long-term operating costs. For different regions and working conditions, diesel jaw crushers can be configured with reliable engine brands including Cummins, Perkins, Weichai, and Kubota.
| Engine Brand | Key Advantages | Recommended Applications |
| Cummins | High reliability, strong power output, and global service support | Heavy-duty mining, quarrying, and remote projects requiring long operating hours |
| Perkins | Stable performance, fuel efficiency, and wide aftermarket support | Export projects, contractors, and continuous crushing operations |
| Weichai | Cost-effective solution with easy maintenance and competitive spare parts supply | Mining and construction projects in regions with flexible emission requirements |
| Kubota | Compact design, low noise, and efficient operation | Small mobile crushers, urban demolition, and light-duty applications |
Engine selection should consider working environment, required capacity, fuel availability, emission standards, and local service support. Zhongyi can provide suitable diesel power configurations based on project requirements.
Applications
Diesel jaw crushers serve as primary crushers in operations where grid power is unstable, absent, or impractical to deploy. Typical duty covers ore preparation, aggregate production, and demolition recycling at sites ranging from small artisanal mines to large contracting jobs.
Diesel Jaw Crusher Specifications
Different projects require different crushing capacities, mobility requirements, and operating conditions. The following specifications provide a reference for selecting the right diesel jaw crusher model. Customized configurations are available based on material characteristics, production targets, and site requirements.
| Model | Screen Size (mm) | Deck Layers | Max Feed (mm) | Capacity (t/h) | Motor Power (kW) | Transport Dimensions (mm) | Weight (t) |
|---|---|---|---|---|---|---|---|
| ZY-1548S | 1,500 × 4,800 | 2 | ≤250 | 60–180 | 52 | 10,500 × 2,450 × 3,800 | 18 |
| ZY-1848S | 1,800 × 4,800 | 3 | ≤300 | 80–250 | 66 | 11,200 × 2,680 × 4,100 | 22 |

Note: Reference values based on medium-hard limestone (compressive strength ≤200 MPa). Actual capacity varies with material hardness, feed gradation, and engine load. Contact Zhongyi for selection based on your site conditions.
Diesel Jaw Crusher Fuel Consumption
Fuel consumption is a key operating cost for diesel jaw crushers and depends on engine power, crusher load, material hardness, and production capacity. In general, larger engines provide better fuel efficiency per ton when operating at suitable loads. The following values are typical references under normal crushing conditions:
| Engine Range | Output Range | Typical Fuel Consumption |
| 8–25 hp | 1–10 t/h | 0.4–1.2 L/t |
| 55–110 hp | 30–80 t/h | 0.20–0.40 L/t |
| 132–280 hp | 100–250 t/h | 0.18–0.32 L/t |
Actual fuel consumption varies depending on feed size, material characteristics, operating conditions, and engine maintenance. Maintaining the crusher within the recommended load range helps improve combustion efficiency, reduce fuel waste, and extend engine service life. Proper equipment selection is the key to achieving lower operating costs.
How to Select the Right Diesel Jaw Crusher
Selecting a diesel jaw crusher requires matching the machine with material conditions, production targets, and site requirements. Key factors include feed size, material hardness, engine power, and emission standards. Standard jaw chambers typically handle feed sizes up to 600 mm and materials up to 320 MPa. For highly abrasive materials, reinforced jaw plates and suitable engine power are recommended to maintain stable performance.
Engine selection should match the required capacity and operating environment. Smaller projects below 50 t/h may use compact diesel engines, while higher-capacity applications require stronger power systems. Buyers should also consider local fuel quality, spare parts availability, and chassis type, choosing between trailer-mounted, skid-mounted, or tracked configurations based on mobility requirements.
For engine matching, emission compliance, and customized diesel jaw crusher solutions, contact Zhongyi for a configuration based on your project conditions.
Diesel Jaw Crusher Price Factors
Diesel jaw crusher prices vary significantly depending on machine configuration, engine selection, capacity, and application requirements. The main cost factors include diesel engine brand and emission standard, jaw chamber size, chassis type, wear parts, and optional equipment. For example, higher emission-class engines, larger crushing frames, tracked chassis, and complete crushing stations with feeders and conveyors will increase the overall investment.
Other factors such as wear-resistant jaw plates, dust suppression systems, remote monitoring, export packaging, and shipping requirements can also affect the final quotation. Instead of a fixed catalog price, Zhongyi provides customized pricing based on production capacity, material conditions, engine requirements, and project location.
