DOPPIATRAC DR400

DOPPIATRACK DR400Double Roll Crusher

The DR400 double-roll crusher is a track-mounted, self-powered machine, that excels in feeding, crushing, and stockpiling for medium to hard bituminous coal applications.

Equipped with a custom-designed 3636 double drum roll crusher, it minimises fines production more effectively than any other crushing solution. The roll crusher forces material through a precisely maintained gap, using only the energy needed to reduce material to the desired size.

Engineered for durability, the DR400 incorporates enhanced safety features and a proven track record of performance. With thousands of hours of field testing, its safety-focused design includes comprehensive guarding around all access, nip, and crushing points to reduce injury risks.

Product Features

DOPPIATRAC DR400
icon

The DR400 is track-mounted, featuring heavy-duty construction with integrated planetary drives and a tracking pendant, enabling full site mobility and rapid setup.

icon

The DR400 features a heavy-duty belt feed hopper with a 6m³ capacity, a low-level drop-down rear feed flap with compatibility for side feeding by a front-end loader and rear feeding by a primary mobile crusher.

icon

Featuring a unique crushing action, the double-roll crusher minimises fines generation and provides efficient performance with low kilowatts per ton produced, capable of a single pass for desired top sized end product. Spring back drum mechanism for tramp release.

icon

Variety of segment options to suit end product requirements and size. Replaceable drum segments allow for easier adaptability for various project demands.

icon

The product conveyor provides a 3.7m stockpile height to maximise stockpile volume or for discharge into a screen.

icon

The DR400 conveyor is equipped with a 1.2m wide flat belt for high volume output.

icon

The product conveyor is hydraulically folded for ease of transport.

icon

The fully guarded design enhances safety, equipment longevity, and operational reliability by protecting critical components from coal dust and debris, reducing maintenance downtime, ensuring compliance with safety and environmental regulations

Extended Benefits

01Improved Product Quality

Produces fewer fines than conventional crushers, ensuring compliance with coal quality standards.

02Increased Yield

Maximises sellable coal through single-pass processing, eliminating secondary screening or crushers, saving time and energy for soft coal.

03Minimised Material Degradation

Eliminates double handling, reducing costs for heavy equipment usage.

04Cost Competitiveness

Delivers low cost per ton with fuel-efficient, high-throughput production.Delivers low cost per ton with fuel-efficient, high-throughput production.

05Extended Equipment Lifespan

Requires low maintenance due to minimal wear from soft coal crushing.

06Enhanced Operator Safety

Safety pull cords along the conveyors and five strategically placed emergency-stop buttons allow rapid isolation in emergencies. Additionally, the DR400 features a mandatory sequential startup sequence with audible warnings before each function, alerting personnel within an unsafe proximity to ensure maximum safety.
