Hard Rock Crusher Ready for Tough Jobs | DMJ140H Track-Mounted Mobile Jaw Crusher Successfully Delivered by Shanghai Dongmeng Heavy Industry

Dual-power flexible switching, intelligent integrated design, reliable performance for hard rock crushing projects

As a star model of the DMJ series track-mounted mobile crushing plants from Dongmeng Heavy Industry, this delivery marks not only the fulfillment of a customer order, but also the practical application of Dongmeng’s technical expertise in high mobility, energy-saving dual-power systems and hard rock crushing.

### Dual-power Free Switching to Optimize Operating Costs

Fuel and electricity expenses are always key concerns for crushing plant operators. The DMJ140H is equipped with a diesel-electric dual-power system, allowing seamless switching between two power modes. Operators can select the optimal power source according to local power supply conditions to cut operational costs and boost profitability.

### Intelligent Integration: One-key Remote Control & Fast Site Relocation

This crawler mobile jaw crusher features a highly integrated design, combining vibrating feeding, jaw crushing, belt conveying and iron removal functions into one compact unit with a small footprint.
It comes with a 9 m³ large-capacity hydraulically foldable hopper. Side and rear plates can be folded hydraulically, and opening, closing and locking operations are controlled via a portable remote controller with one single click.
The feeder is driven by dual-motor vibrators. The gripper gap and screen mesh size can be adjusted flexibly to suit pre-screening conditions, with modular wear-resistant liners for long service life.
The main conveyor adopts a B1200 belt conveyor driven by dual reduction motors, ensuring smooth discharge and efficient transportation. It can be put into production immediately on arrival and relocated quickly between sites.

### Powerful Core: Cummins Dual-power System, Free from Grid Restrictions

The machine is fitted with a Cummins mining-specific engine, which delivers ample, stable and durable power to adapt to harsh mining working conditions.
As a dual-power model, the DMJ140H has its own power unit and generator set and can operate independently without external grid power. Compared with single-power units that rely on grid supply, it solves power shortages in remote mines and guarantees continuous stable production even on complex terrain.

### Robust Specifications for High-hardness Crushing Applications

Built for hard rock crushing, the main crusher is Dongmeng’s high-efficiency European-style J1480 jaw crusher. It accepts a maximum feed size of 820 mm and handles materials with compressive strength up to 300 MPa. It features large feeding capacity, high output and long service life.
A permanent magnetic iron remover is fitted as standard on the conveying section, providing stable iron removal protection for the whole machine.

From high-efficiency crushing and automatic iron removal to remote control and rapid relocation, Dongmeng Heavy Industry maintains strict quality standards to deliver stable performance for all types of aggregate crushing projects. Order deliveries continue on schedule. We are ready to customise crushing and screening solutions tailored to your project requirements.https://dongmeng-global.com/products/mobile_jaw_crushing_station/
