    Feeding

    Feeders and conveyors transport materials from one stage of the mining process to the next.
    Bonfiglioli is an expert on issues related to these applications: the high breaking torque required at startup, the high load shocks caused by material drops and the dusty environments in mines are only a few of the challenges that our products can successfully overcome. We can provide complete solutions for feeders and conveyors with integrated base plates and torque arms which are protected against harsh environments with special seals and paints to simplify machine design for our customers.
    Furthermore, our clients can complete their drive selection through a wide range of inverters for tuning the operating speeds of feeders and conveyors and thus reducing energy consumption.
