Mineral Processing Equipment Specialists
PBA Projects is a Engineering Project Design House delivering optimal Processing Solutions in the Minerals and Metals Mining Industry.
Streamlined collaboration between its Engineering Departmants allows PBA Projects to offer tailor-made turnkey solutions to meet client’s requirements.
Multi Disciplinary Engineering
We also have experience in iron ore in which jig tailings is processed via Ultra High Dense Medium Separation (UHDMS) plants to recover high grade ore to the tailings due to inefficiencies in the jigging process.
Our process engineers are experienced in the design of Dense Medium Separation, Gratify Separation and Comminution Plants for the Minerals Industry.
A Brief Outline Of Our Technical Expertise Includes:
- Feasibility Studies
- Developing Process Flow Diagrams
- Mass Balancing
- Equipment Sizing and Selection
- Piping and Instrumentation Diagrams
- Developing Training Manuals
- Operator Training
- Commissioning
- Plant Auditing
- Process Control Development
PBA Design and Draughting Services
PBA provides design and draughting services to several clients in the marine and land-based mining and mineral industries. Typical process plants include Marine Diamond Mining, Coal, Iron Ore, and Phosphate, to name a few.
What we do:
Design and draughting are predominantly performed in a 3D modelling environment, starting with a client’s brief or concept.
Our Approach:
From process designs and PFD’s (Process Flow Diagrams), 3D layouts are generated using 3D modelling of each of the following discipline areas:
- Civils (where applicable)
- Structures (structural buildings and treatment plant structures)
- Vendor equipment (crushers, vibratory screens, separators, in-house materials handling equipment, etc.)
- Plate work Items (Chutes, Launders, bins/silos, hoppers, screen underpans/sumps, etc.)
- Piping (process, air, water, etc. In most cases, the Instrumentation from P&ID’s are included in the 3D models.)
Reviews and approvals:
All of the above culminate in an overall plant layout using AutoCAD 3D Navisworks, which is used for presentation and process of internal and external reviews and final client approvals.
Software capabilities:
Each area of the above disciplines is taken to a detailed 3D modelling design level in the following Autodesk Products:
- Structures and Plate Work – Advanced Steel
- Vendor Equipment – Autodesk 3D
- Piping – Autodesk Plant 3D
- Electrical and Instrumentation -Autodesk Plant 3D – (note only if in PBA Scope)
- 3D Model Viewer – Autodesk Navisworks
- 2D GA’s – Autodesk Revit
Shop Detailing outputs:
The final outputs of the approved 3D models in each area, after final checks and clash detections, are to generate the shop detailing, isometric view, assembly drawing, and part details of:
- The structures, which consist of steelwork, stairs, handrailing and flooring.
- The Plate work, including lining and lining details where applicable.
- Piping outputs are Isometrics and details.
Included in the outputs are lists and material take-offs
2D General Arrangements:
2D Mechanical, Piping and Structural General Arrangement Drawings are generated in Autodesk Revit after the Shop Detailing Phase is completed.
Electrical Control and Instrumentation (EC&I)
Our team has benefitted from extensive E C & I experience and utilizes it in the design of the plants.
The electrical design includes motor control centers, switchboards, schematic drawings, loading & cable schedules.
The instrumentation design includes PLC panels, field panels, instrument selection and positioning, block & loop diagrams, allocation and cable schedules.
All regulations and standards governing E C & I design, and plant operational safety are encompassed into our design.
If required, we oversee the entire E C & I fabrication, installation and testing of the equipment prior to transportation to site.
We pride ourselves in the pre-commissioning of the assembled equipment prior to delivery so that site installation, commissioning and hand over time is reduced.
Mechanical
Our Mechanical Engineering expertise ranges broadly to incorporate not only designs of systems such as Pumping, Air Reticulation, Ventilation, Vacuum, Dust Extraction, High-and Low-Pressure Fire Systems and Foam suppression systems, for the containment and prevention of fire hazards in rubber lined areas of our treatment plants, but also to generate all reports associated with our designs, including the Design and Rigging Philosophies.
Structural Design Department
PBA offers in-house specialized structural steel design analysis for the onshore and offshore mining industry.
Offshore mining structures are designed to withstand various ship motion conditions as well as static and dynamic vibration loads. Marine structures are designed to SANS, Anglo-American Design Standards and Specifications and the applicable Marine Mining Codes, for a Static Analysis and Dynamic Analysis (Vibration Analysis).
Onshore land-based mining (modular or non-modular) structures are designed to withstand Static and Vibration loads. These structures are designed to SANS Codes and Anglo-American Design Standards and Specifications.
Bulk flow material holding platework items such as hoppers, bins, underpans and sumps are fully loaded and analyzed to withstand vertical and horizontal pressures caused by static or flowing materials.
Structural inspections and vibrational analyses are performed on existing plant structures which support vibrating machinery that can cause excessive vibration deflections on structures. Onsite vibration measurements of new and existing plant structures are compared to Anglo’s allowable vibration deflections for vibrating equipment or machinery.
