ABOUT US
JJL Projeto e Consultoria Ltda., is a consolidated engineering company, with vast experience in industrial projects and numerical simulations. JJL’s objective is to develop and execute projects in diversified segments, such as belt conveyors mechanical and structural calculations, heavy boilers, metal structures and DEM simulations (material flow analysis), all of which strictly following national and international standards, ensuring quality and meeting deadlines.
The company relies on professionals with experience in engineering projects. It has modern technical and managerial methods that provide the appropriate structure for the execution of activities with high-level quality, precision and speed. Its employees are committed to the quality of the final product, ensuring compliance with deadlines and safety, and always delivering the required quality.
COMMIMENT
We consider each project as unique and always aim to offer the best to achieve excellence in results, making each finished project always a source of pride and satisfaction.
QUALITY AND ENVIRONMENTAL POLICY
Environmental preservation must always be seen and understood as an asset in any company. JJL applies state-of-the-art technologies within its simulations, allowing problems such as particulate dispersion in transfers, to be considered and solved, resulting in transfers which no longer disperse environmental contaminants.
MISSION
Offer creative and integrated solutions for the needs of each project, valuing the quality of services provided and continuous improvements.
VISION
To be a reference in numerical simulations applied to ore processing, working efficiently in partnership with large companies, ensuring continuous improvements and proposing intelligent solutions.
VALUES
- Commitment to quality and continuous improvement of process’ effectiveness
- Seek, in its projects, to improve the quality of life of operators and maintainers
- Understanding that environmental preservation is an asset
- Constant technical improvement of our people and tools
- Maintain ethical practices with partner companies
- Maintain respect for others
- Meet the requirements requested by our customers
SERVICES

Structural calculations of beams and cargo handling systems.
PORTFOLIO
Structural dimensioning of heavy boilers
Structural calculations of heavy boilers, pressure vessels and general tanks, applying the FEA methodology.
Obtaining loads using FEA DEM coupling
Structural calculations of heavy boilers, applying DEM and FEA couplings, allowing the capture of actions and loads numerically, where there are no analytical equations that contemplate the geometry.
DEM ANALYSIS AND SIMULATIONS
Material transfer chutes, are critical points of any operation, if not correctly designed. Discrete element modeling has been successfully used in industry to simulate various processes. The advantages of using this technology are immense, as it is possible to visualize in detail the flow of materials within boilers, anticipating possible problems in the flow, mapping areas of wear, capturing the actions of impact on the sides or their internal pressures, among other benefits. With this simulation, JJL can design sacrifice or wear parts, with programmed, quick, and safe replacement.
SPECIALIZED TRAINING
JJL values the training and qualification of professionals, therefore, it develops training programs in Application Engineering Topics, aimed at the dissemination of structural and mechanical theories in the areas of material handling and storage.
Studies of acidental avalanches of material
Study of the variation of internal pressures in silos, chutes and hoppers during accidental avalanches of material.
Capturing these actions is fundamental for the dimensioning of the silo structure itself, but mainly for its support structure.
Observation of flow in silos
Within the scope of Rocky – Ansys or DEM – FEA couplings, we can validate the behavior of the material in a silo with the technical literature available, such as the Australian Standard AS 3774—1996.
Chute designs for material alignment on the receiving belt
Settling studies are designed to combat one of the root causes of conveyor belt misalignment. Among the numerous advantages of simulating continuous material flows is to anticipate the profile of these materials on the receiving conveyors, and thus correct misalignments, impacts and poor distribution of the material transported on the belts.
Feed simulation of a primary crushing
JJL, with its analysts, can simulate the behavior of entire areas where the material flow can be studied, and the process equipment adjusted to its behavior.
SMART CHUTES
It is a transfer concept, developed and patented by JJL, which recognizes that industries must operate with high performance, safety, reliability and efficiency. By mapping wear zones, SMART CHUTES are designed to enable minimal, quick and safe interventions due to the development of modularized wear or sacrifice parts, without the need to expose employees to confined and unhealthy environments.
MATERIAL CALIBRATION
Regardless of the type or objective of the study to be performed, it is essential not only the physical understanding of the adopted properties, but also calibrating and parameterizing these data in the simulated models. Field visits, with clients and their employees, to collect data and observe the flows to be studied are as important as the laboratory tests that may be presented.
JJL Engenharia values the quality of the work delivered, the accuracy of the solutions adopted and compliance with pre-established deadlines, always aiming to safely meet the demands of our customers.
