Crushing & Grinding & Material Handling

Applications

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.

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.

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.

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.
Slurry processes

Applications

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.

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.

Flotation
Flotation cells mainly consist of big tanks where an impeller keeps the water/material solution rotating at a high speed. Use of specific chemical reagents and the possible addition of air in the solution enhances separation of the ore from the liquid.
For this application, Bonfiglioli provides helical bevel or parallel shaft gearmotors with more bearings. Output configurations are usually reinforced bearings to withstand by the machine impeller on the shaft. In some models, the machine requires injection of high-pressure air to maximize separation of the material from water. In this case, Bonfiglioli provides a gearbox equipped with a pass-through hole on the output shaft and with a specific interface on top of the gearbox for the pipeline connection.
HDOs are usually driven by belt transmissions, while HDPs are directly connected to the motor with a bell housing. Independent coolers are usually installed on bigger machines. Drywell is a commonly required feature.
Conveying

Applications

Vertical conveying

Pipe conveying

Roller conveying

Flow material conveying

SPIRAL CONVEYOR
Our solution consists of a complete drive transmission package, from the gearbox to the decentralized inverter. For spiral conveyors, our range is based on bevel gearboxes, always in combination with our IE3 electric motor and our internal panel inverters. In applications where high efficiency is required, we can offer our synchronous reluctance motor with IE4 efficiency.

Bucket elevator
Bonfiglioli provides complete bucket elevator solutions for material pickup. Additional options, such as hydraulic couplings between the motor and gearbox, monitoring sensors and inverters maximize reliability and performance.

Screw conveyor
The screw conveyor moves the material into a round pipe. Its precision is fundamental to the process. Bonfiglioli solutions provide optimized torque to drive the material into the pipe and minimize sliding through the spiral.

Belt & chain conveyor
Belt and chain conveyors are used in many industries to transport all kinds of material: metal, mining, coal, chemical, food, ports and others.
Bonfiglioli knows how the dimension of the correct solution taking loads and all other specific needs into account.
Our offerings span from harsh and explosive atmospheres to food contact environments, and offer a wide range of gearmotors and inverters.

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.

Overland conveyor
Continuous operation and long distances are two elements that make overland conveyors challenging applications. Our solutions can handle high power requirements and are easy to maintain, offering an ideal option for this process.

Spiral Conveyor
Spiral freezers pose a challenge due the low temperature and the specific environmental conditions. Bonfiglioli products support continuous feed for spiral freezers providing a dedicated solution that allows food manufacturers to quickly freeze their products.

Baggage Conveyor Systems
From check-in to boarding gate, arrivals to baggage claim, conveyor speed is crucial in preventing slow system speed. Bonfiglioli provides the complete solution, combining high-efficiency gearmotors and smart frequency drives to guarantee optimal speed and long hours of operation.

Conveying
Thanks to an extensive selection of features and space efficiency, we offer products for a variety of conveying systems.
High dynamic response and energy efficiency are signature Bonfiglioli features.
Furthermore, our cost-effective and extended service intervals guarantee low cost of ownership.
