DoppiaTrac DR400 – next generation double-roll crushing solution for coal applications
The DoppiaTrac DR400 is a track-mounted self-driven, feeding, crushing and stockpiling machine that is purpose-engineered to tackle medium to hard bituminous coal applications. This innovative crushing solution, manufactured by Pilot Crushtec, features a custom-designed 3636 double drum roll and has been making its mark on coal operations where it has established a reputation for superior performance and efficiency.
Features
Capable of processing feed sizes up to 180 mm, the DoppiaTrac DR400 guarantees precise product sizing in a single pass, delivering material as small as 35 mm without the need for additional screening. The machine operates with a unique crushing action that minimises fines generation, setting it apart from conventional impact crushers.
This fully mobile crusher is designed for ease of transport and quick setup, making it a highly flexible solution for site operations. It can operate independently when loaded by front-end loaders or can be integrated seamlessly into a crushing train, allowing communication between upstream and downstream equipment for optimal performance.
At its core, the DoppiaTrac DR400 is powered by the latest generation Volvo engine, providing a highly efficient crushing process that consumes minimal energy per ton produced. Additionally, the crusher’s low transport weight and compact design enhance its mobility, while the machine’s robust construction ensures it meets the demands of mining environments.
The DoppiaTrac DR400 features a heavy-duty belt feed hopper with a capacity of approximately 6m³. It is equipped with a low-level drop-down rear feed flap and can be fed from the side by a front-end loader or from the rear by a primary mobile crusher. The robust feed belt is built with durable materials, including a Class 630/4 ply belt with a 5 mm top cover, ensuring reliable performance under tough conditions.
One of the standout features of the DoppiaTrac DR400 is its tailored double-roll crushing action, designed to minimise fines. Unlike impact crushers that produce excess fines through high-energy impact, the double-roll crusher maintains a constant gap, using only the necessary energy to break material down to the desired size. When operating at full capacity—up to 400 tons per hour—the efficiency is further enhanced as the feed material enters the crusher at the same speed as the spinning drums, minimising attrition and friction.
The machine is equipped with a 1.2 m wide conveyor belt, designed for hydraulic folding during transport and offering a stockpile height of up to 3.7 m, providing ample capacity for coal stockpiling. The DoppiaTrac DR400 is mounted on a crawler track system for optimal site mobility. Radio remote control ensures easy tracking, with an optional pendant control box also available for added convenience during site operation.
With its cutting-edge technology, robust design and focus on efficiency, the DoppiaTrac DR400 is the ideal solution for operations requiring reliable high performance crushing in coal applications.
