Hamilton By Design offers engineering-led 3D LiDAR scanning and scan-to-CAD support for coal handling and preparation plant projects in Hwange, northwest Zimbabwe. We help mining operators, maintenance teams and project engineers capture existing plant layouts and develop mechanical modifications around actual site conditions.
Whether the project involves a replacement transfer chute, conveyor modification or coal wash plant upgrade, reliable measurements provide a stronger starting point for design and fabrication. Our approach connects site capture with 3D modelling, mechanical engineering and practical drawing deliverables.
Zimbabwe projects are assessed individually, with site scanning arrangements, mobilisation, access requirements and remote engineering support agreed during project scoping.
Coal Handling and Wash Plant Engineering in Hwange
Hwange is an established coal mining and processing centre. Coal operations in the region include run-of-mine crushing, conveyor transport, washing and product handling. Makomo Resources, for example, describes coal washing using dense medium separation, magnetic separation and spiral separation.
Coal handling and preparation plants depend on interconnected equipment. A modification to one chute, screen or pump arrangement can affect surrounding pipework, support frames, access platforms and maintenance space.
For existing facilities, the challenge is often understanding how replacement equipment will fit into a plant that has changed over many years. Original drawings may show the initial installation while overlooking later repairs, equipment replacements and site modifications.
3D LiDAR scanning creates a current dimensional reference for planning these upgrades.
Why Scan a Coal Plant Before Modifying It?
Traditional measurements can capture individual dimensions, but complex plant upgrades require an understanding of the relationships between equipment.
A replacement chute may need to connect to an existing screen outlet, clear a support beam, discharge onto a conveyor and remain accessible for maintenance. Measuring each feature separately can leave gaps in the information needed for design.
3D laser scanning captures visible surfaces as a point cloud. Multiple scan positions are registered into a coordinated dataset, allowing designers to examine equipment positions, elevations and available space.
For a Hwange CHPP or wash plant project, scanning can help teams:
- Establish existing conveyor and transfer point geometry.
- Identify the space available for replacement equipment.
- Check proposed layouts against surrounding plant.
- Plan pipe routes and maintenance access.
- Prepare drawings using current site information.
- Reduce repeat visits for measurements already captured.
The scanning scope should reflect the engineering task. A targeted survey of a transfer station or pump area may provide the information required without scanning the entire facility.
LiDAR Scanning for Coal Conveyors and Transfer Chutes
Coal transfer points bring together conveyor discharge geometry, receiving belts, chutes, support frames and access systems. Differences between drawings and installed equipment can complicate replacement work.
Scanning can capture the visible geometry around conveyor head pulleys, chute exteriors, hoppers, guards, support members and adjacent platforms. This information provides a reference for modelling replacement components and checking their installation clearances.
Hamilton By Design can support:
- Replacement transfer chute layouts.
- Conveyor discharge and receiving interfaces.
- Hopper and feed chute modifications.
- Wear liner arrangements.
- Mechanical connection details.
- Fabrication and assembly drawings.
- Maintenance access reviews.
Chute performance also depends on coal properties, moisture, particle size distribution, belt speed and throughput. Scan data establishes the available geometry, while operating information guides the design.
Internal chute surfaces require suitable access. Scanning the exterior does not reveal concealed liners, plate thickness or material build-up inside an enclosed chute.
Scanning Coal Wash Plant Equipment
Wash plant upgrades often involve congested layouts with equipment positioned across several levels. Floors, beams, pipe racks and existing maintenance arrangements can restrict the space available for new equipment.
A scanning scope can include accessible areas around:
- Feed and distribution arrangements.
- Screens and dewatering equipment.
- Dense medium cyclones and associated pipework.
- Sumps, pump boxes and slurry pumps.
- Product and reject conveyors.
- Process water systems.
- Pipe racks and equipment supports.
- Platforms, stairs and maintenance access.
Before scanning, we identify the equipment interfaces that need measurement and whether components must be isolated, cleaned or opened.
Dust, water spray, moving equipment and obstructed sightlines can affect capture quality. Planning suitable scan positions helps improve coverage and identify where supplementary measurements are required.
Scan to CAD for Existing CHPP Upgrades
A point cloud provides a dimensional reference. A CAD model converts selected information into geometry that can be used for design, coordination and drawings.
Hamilton By Design develops models using SolidWorks and AutoCAD, with deliverables selected to suit the client’s project and software requirements.
Modelling can focus on the equipment being changed and the surrounding features needed to check its fit. For example, replacing a screen discharge chute may require the screen outlet, chute envelope, receiving conveyor, support members and maintenance access to be modelled.
An agreed level of detail keeps the work focused. Measured geometry, approximate representations and features requiring additional verification are identified during the modelling process.

Mechanical Design and Fabrication Support
Following site capture, the next step is developing a modification that suits the operating plant and can be manufactured and installed.
Hamilton By Design can assist with mechanical design for conveyor interfaces, transfer chutes, hoppers, pump boxes, pipe routing, equipment arrangements and guarding layouts.
Drawing packages can communicate component dimensions, assembly requirements, connection details and installation interfaces. This helps fabrication teams understand how the proposed equipment relates to the existing plant.
Critical features such as bolt hole patterns, flange faces and machined fits may require direct measurement or a separate detailed survey. These requirements are identified according to the fabrication tolerance and intended use.
Structural verification, process design and local certification requirements are defined within the project scope, with appropriately qualified specialists involved where required.

Prepare for Shutdown Installation
A planned shutdown provides limited time to remove equipment, install replacements and return the plant to service. Capturing existing conditions before the shutdown supports earlier design and fabrication decisions.
A coordinated model can help review:
- Component delivery and removal routes.
- Equipment installation clearances.
- Access for lifting and handling.
- Interfaces with existing pipework and supports.
- Temporary obstructions.
- The proposed installation sequence.
Clash checks can identify geometric conflicts before components arrive on site. This gives the project team an opportunity to adjust the design while changes are easier to manage.
For staged projects, accessible areas may be scanned during operation, followed by additional measurements during isolation. The approach must be coordinated with the site’s operating conditions and safety procedures.
Deliverables for Hwange Coal Plant Projects
Deliverables are selected around the purpose of the project and may include:
- Registered 3D point clouds.
- Existing-condition CAD models.
- Plant layout and general arrangement drawings.
- Sections and equipment interface details.
- Mechanical design models.
- Fabrication and assembly drawings.
- PDF review packages.
Point cloud formats can include E57 or RCP. Model exchange formats may include STEP or other agreed CAD formats.
Before work starts, we agree on coordinate references, model detail, file formats, revision requirements and dimensional acceptance criteria.
For clients with existing scan data, Hamilton By Design can assess whether the dataset is suitable for remote modelling and mechanical design. Registration quality, coverage and critical interfaces need review before the information is relied on.
Frequently Asked Questions
What does CHPP mean?
CHPP stands for coal handling and preparation plant. It generally covers activities such as coal crushing, sizing, washing and product handling. The equipment and process configuration vary between facilities.
Can LiDAR scanning be completed while a wash plant is operating?
Some accessible areas may be scanned during operation, subject to site approval and conditions. Moving equipment, dust and water spray can affect capture quality. Scanning inside enclosed equipment or hazardous areas may require isolation and specific access arrangements.
Can scanning help with replacement coal chutes?
Yes. Scanning establishes the visible geometry around a chute and its connections, supporting replacement design and fit checks. Internal surfaces and critical fabrication interfaces may need additional measurements.
Does scanning confirm equipment condition or structural capacity?
A scan records visible surface geometry. Plate thickness, material properties, weld integrity and load capacity require appropriate inspection and engineering assessment.
What scanning accuracy should we specify?
Accuracy should match the intended use. Plant layout coordination and precision component fabrication have different requirements. Project tolerances and verification methods should be agreed before scanning begins.
Can Hamilton By Design use scans supplied by a Zimbabwean survey company?
Yes, subject to a review of the dataset. We can assess registration, coordinates, coverage and suitability for the proposed modelling or design scope. Additional measurements may be required where interfaces are missing or insufficiently resolved.
