Applications

Unloading

Unloading procedures in a mining plant are usually done by a train positioner coupled with a wagon tippler.
Bonfiglioli solutions for train positioners have customized gearmotors adapted to the machine design. Furthermore, the products we use in these applications feature special seals.
Wagon trippler:
Wagon tripplers rotate train cars together with the rail section beneath them to unload the material.

Crushing

Crushing is a crucial process in the mineral industry, so reliability of the products for these applications must be extremely high to ensure process continuity. Bonfiglioli solutions for crushers are extremely robust and manufactured to the highest quality criteria. Our heavy-duty products for these applications can operate 24/7/365 and ensure maximum operational time. Furthermore, our solution can be customized with torque arms adapted to the machine design and completed with highly corrosion-resistant paints and seals for mining environments.

Stacking & reclaiming

Multi-functional machines, such as stackers/reclaimers, store and gather material in large mining processes.
Bonfiglioli can provide solutions for all stacker/reclaimer drives. The products we supply are tailored to match the specific requirements of each machine drive: different brakes, forced lubrication, integrated base plates, cooling fans and oil expansion tanks are just a few examples of how we can meet our customers’ needs.
Finally, all the solutions can be further customized with a set of features specifically developed to resist the harsh mining environment.

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.

Thickening

Separating the minerals from the water using gravity sedimentation means controlling the speed and at the same time facilitating the precise movements.
Thickeners are moved by single or multi-drive solutions. For this application Bonfiglioli offers vertical linear planetary gearboxes with very high reduction ratios to obtain speeds of <1 rpm on the output shaft, with particular attention to possible torque overloads, depending on the solid material layer thickness moved by the rake. For this reason, our solution can mount load cells to monitor and eventually limit the transmitted torque.

Dewatering

Focusing on solid/liquid separation, the belt filter presses the product with mechanical pressure to squeeze the water out of the sludge. Flexibility in layout and mounting positions as well as high resistance in harsh, dusty and ambient conditions are key features that our products can deliver.

Dewatering

Spiral classifiers are designed to settle and dewater relatively coarse particles from high volume, low percent solid volume streams. Flexibility in layout and mounting positions as well as high resistance in harsh, dusty and ambient conditions are key features that our products can deliver.

Milling

Bonfiglioli solutions for flaking and milling ensure smooth operation to optimize the grinding of wheat into flour. For speed control, Bonfiglioli provides a complete drive solution from the gearmotor to the inverter. Bonfiglioli drives can safely operate in dusty milling environments, and their easy maintenance reduces downtime.

COOKING AND FREEZING PROCESSES

The Bonfiglioli solution offers a complete Drive Transmission package, from gearbox to inverter. With spiral belts for freezing and reheating processes, our offering is based on planetary gearboxes with or without input bevel gear, always in combination with our IE3 electric motor and our internal panel inverters. In applications where high levels of efficiency are required, we can offer our synchronous reluctance motor with IE4 efficiency. Furthermore, our gearmotors are capable of operating in extremely low temperatures, such as those required by the freezing process, and stand up to the most intense washing procedures.

Raw material handling

Feeding, washing and sorting processes require reliable, robust products designed for conveyor systems. Regardless of the type of machine used for this first handling phase, Bonfiglioli can provide solutions that perfectly meet our customers’ need for dynamics, space and efficiency.
Our customers can also rely on a product line specifically conceived for applications involving frequent washing procedures and humid environments.

Jib Cranes

Bonfiglioli solutions for horizontal and low handling applications are cost-effective, compact and reliable.
Our products are designed to meet and exceed the demanding requirements placed on these cranes: from the high radial loads of the slew drive to the precision necessary in the hoisting speed control and finally to the dynamics of the cross travel drive.

Shiploader/Unloader

Ship loaders/unloaders operate in one of the most demanding environments. The atmosphere at the docks can be extremely corrosive, and these machines must be able to work under all weather conditions.
Bonfiglioli is aware of these challenges and the solutions we provide are adapted with specific features for safe operation under such conditions and maximum reliability in every work situation.

Feeder

A feeder typically requires relatively low speeds to transport heavy materials. This calls for high ratios and robustness. Bonfiglioli gearmotors combined with Bonfiglioli inverters achieve high performance while resisting severe impacts and temperatures.

Secondary Shredding

A planetary torque rating over 2 MioNm guarantees a complete range of shredding machine applications.
Thanks to a high peak load capacity, our planetary gears offer best-in-class mechanical performance.
Fully interagatable with Bonfiglioli drives for a complete package solution.
