Lithium in Argentina: bearings, pumps, belts and transmission for brine and processing plants in the Puna

Lithium production in Argentina is concentrated in high-altitude salt flats, where extraction and processing plants operate under extreme conditions: large thermal amplitude, intense solar radiation, strong winds and the presence of corrosive brine. These conditions demand highly reliable mechanical components to avoid unplanned downtime.

In brine plants, critical equipment includes centrifugal pumps, conveyor belts, agitators, filters and crystallization systems. All of them depend on bearings, housings, chains and pulleys that must withstand heavy loads, vibrations and aggressive environments.

Choosing the right components not only extends equipment life but also reduces maintenance costs and improves operational safety. That's why in this guide we review the key elements for each stage of the process.

Centrifugal pumps that transfer brine from wells to evaporation ponds work with abrasive fluids and high pressures. For their shafts, deep groove ball bearings or tapered roller bearings are often used, depending on axial and radial load. In high-load and misalignment applications, spherical roller bearings are a robust option.

In our catalog we distribute spherical roller bearings from recognized brands such as SKF, FAG and LINK-BELT. For example, codes 22325 and 22361 from SKF, or 20222-MB and 20240-MB from FAG, are common references in mining equipment. We also work with 6203U and 22318 from LINK-BELT for specific applications.

It is essential to verify proper fit, lubrication and sealing to prevent brine ingress. A contaminated bearing fails prematurely, so we recommend consulting with our technical team to select the correct model.

Split housings, also called plummer blocks, are essential for mounting bearings on conveyor belt shafts, gearboxes and other equipment. Their split design allows assembly and disassembly without dismantling the entire shaft, speeding up maintenance in lithium plants.

We distribute SKF SAF and SNL split housings, such as SAF 322, SAF 520, SNL 211 and SNL 216. These housings are complemented with covers and accessories, for example TS 34 and TS 52 from SKF, or LO519 and VR317 from TIMKEN, which protect the bearing and retain lubrication.

In brine environments, it is advisable to use covers with efficient seals and ensure adequate lubrication. Our team can advise you on the most convenient configuration for your application.

Roller chains are used in conveyors, elevators and drive mechanisms within lithium plants. They must withstand variable loads and exposure to saline dust, so careful selection of pitch, material and surface treatment is required.

We work with a wide variety of roller chains of different series and pitches, suitable for mining applications. We can quote you the exact chain according to the standard and dimensions you need, whether for replacement or a new project.

We also offer sprockets and accessories to complete the transmission system. Send us the code or measurements of your current chain and we will indicate the compatible alternative.

Pulleys are critical components in conveyor belts that move ore and supplies within the plant. They must resist abrasion, corrosion and high belt tensions. They are also used in lifting and rigging systems for maintenance tasks.

We distribute pulleys of various diameters, rim widths and bushing types, suitable for severe conditions. If you provide the measurements of your current pulley or the manufacturer's code, we will quote the replacement.

It is important to check the alignment and condition of the pulley bearings to avoid premature wear. Our technical team can guide you in the selection.

Couplings transmit power between shafts, absorbing misalignments and vibrations. In lithium plants they are used in pumps, compressors, mills and other rotating equipment. Choosing the right coupling reduces loads on bearings and extends the life of the entire assembly.

We work with elastic, gear, disc and other types of couplings, depending on the application. If you tell us the torque, shaft dimensions and rotation speed, we will recommend the appropriate model.

Correct installation and alignment is key for reliable operation. We have experience in the mining sector and can advise you at every step.

At MR Accesorios Industriales, from Buenos Aires, Argentina, we distribute bearings, housings, chains, pulleys and couplings for the lithium mining industry. We work with recognized brands and can quote the codes you need.
