dynarox Mobile Feeder & Primary Crusher

Engineering & Technological Description

The HAZEMAG dynarox Mobile Feeder & Primary Crusher is a massive, track-mounted primary processing plant that integrates a heavy-duty apron feeder (HAEMAG HAF series) and a powerful primary crusher (such as a sizer or primary impactor) onto a single, heavy-duty mobile chassis. This system is engineered to receive large run-of-mine rocks and heavy blasted material directly from wheel loaders or dump trucks right at the quarry face. The rugged apron feeder, constructed from thick, wear-resistant steel pans, is designed to absorb high-impact forces from falling boulders. It provides a highly controlled, variable-speed volumetric feed directly into the crusher throat, preventing choking and maximizing crushing efficiency. By performing primary crushing directly at the excavation site, the plant eliminates the need for expensive internal truck fleets, allowing the crushed material to be transported out of the quarry via efficient overland conveyor systems.

Technological Benefits & Engineering Value

· Extreme High-Impact Resistance: Heavy-duty steel apron feeder pans absorb massive impact forces from direct truck dumping of large rocks.

· Optimized Volumetric Feed Control: Variable Frequency Drive (VFD) on the feeder pans ensures an even, choke-free material flow into the primary crusher.

· Elimination of Haul Trucks: Crucial cost-reduction solution by bringing primary crushing to the rock face and conveying out, saving diesel and tire costs.

· Highly Efficient Diesel-Electric Drive: The heavy electrical drives provide superior mechanical torque for crushing while reducing maintenance overhead.

· Safety & Operational Protection: Integrates robust mechanical locking systems and hydraulic lift assists to ensure safe wear-part replacement in the field.

Heavy Industry End-Use Applications

· Quarry-Face Primary Crushing: Direct positioning at the blasted rock face to crush massive limestone boulders and feed overland conveyors.

· Cement Feed Preparation: Volumetric dosing and primary reduction of wet, sticky clays and hard limestones for cement kiln feed systems.

· Industrial Mining Operations: High-capacity primary reduction of heavy iron ores, copper ores, phosphates, and potash in rugged open-pit mines.
