Mill Maintenance Monorail

Dynamic Engineering Consultants can assist with your mill maintenance monorail project. We will take care of all the civil, structural and mechanical aspects of your monorail installation project. Because of this, the final product will be tailored specifically for your application. From a cost point of view, a recent project also revealed that our project was only a fraction of the cost of our closest competitor in this area.

Dynamic Engineering Consultants can assist with:

Initial Consultation phase to determine requirements
Civil and Structural Design
3D Modelling and Drafting
Fabrication Quality Assurance

Contact us to discuss your specific needs.

Below are an example of such a mill monorail design.

Load Rating of Equipment and Structures

Sometimes there is a need to retrospectively certify existing structures or equipment. Dynamic Engineering Consultants can assist you to do this. In broad terms, the procedure to do this is broken up in the following steps:

  1. Measure up existing structure or model from drawings
  2. Determine grade of materials of construction
  3. Model in 3D or use SPACE GASS structural analysis
  4. Apply loads and load cases in accordance with the relevant Australian Standard. Latest versions of the Australians can be purchased here:
  5. Iteratively calculate the load that would lead to compliance with the standards
  6. Record in a calculation report
  7. Perform actual load testing if required
  8. Provide nameplate/marking of structure.

Examples of structures on which Dynamic Engineering have applied this process are: monorail structures, maintenance stands, job cranes, platforms, winches etc.

Modular Minesite Washbay Vehicle Ramp Design

Dynamic Engineering Consultants recently completed a 5T capacity Modular Minesite Washbay Vehicle Ramp Design for one of our clients. The client requirements were:

1) Constructed from large welded assemblies that can be transported easily and that would minimise construction time on site – modular.

2) Galvanised surface treatment.

3) Open sections to make it easy to monitor corrosion and damage.

4) Capable of handling certain site vehicles.

5) Fully compliant with the relevant Australian Standards.

6) 5T capacity.

7) Incorporated vehicle wheel guides (safety).

The final design for this ramp is shown below. It complied with all of the above requirements and is currently installed at a few minesites around WA. It was constructed in four large sections that was bolted together on site with splice plates and was also attached to the concrete with mechanical anchors. The all-important feedback that was received from our clients are very positive. The ramp was easy to transport, easy to install, had a quality construction and was easy to use. It is an example of a simple design that just works.

Hopper Structural Design Certification

A hopper collects ore, which typically falls from an overhead conveyer or is dumped by a belt feeder into the bin. This causes dynamic loads and stresses, which need to be taken into account when designing the hopper. Dynamic Engineering analysed our client’s proposed design and found that it would require strengthening in order to reliably withstand the imposed forces. With relatively cheap modifications, a more robust design was implemented – saving our client on future repair and maintenance costs.

Radiation Source Cradle Design and Supply

A radiation source cradle was designed to assist plant metallurgists to easily and safely move radiation sources around inside a process plant.

Due to the weight of the source the cradle was designed to that it can be carried by two people. The cradle weight was kept low by using aluminium for its construction and was fitted with spacers that made it multi functional. It was also furnished with a stainless steel nameplate that contained information regarding the load rating and use.

This includes management up to approx $AU 3mil total project cost. Whether it is a new project or you are looking to expand an existing one, Dynamic Engineering can help you. As part of this services we can assist with the following:

1) Scope of works development

2) Layout drawings

3) Project schedule development

4) Detail foundation design and drafting

5) Detail structural design and drafting

6) Detail mechanical design and drafting

Below are some examples of the projects we have done recently:

Kibble (Back up ball charging) systems

Mills use small steel balls to grind ore smaller for further processing.  A kibble system provides a safe way to charge mill chutes or inlets. Dynamic Engineering can design kibble systems (back up ball charging systems) to suit. Example of such a ball charging system is given below:

Civil / Structural Design and Certification

Dynamic Engineering also provides a civil or structural design service. Below are some examples of our recent work.

Structural work comprises footings and foundations – including drive-in sumps and retaining walls. Here is an example of a container lifter foundation:

Access Systems and Ramps Design

Dynamic Engineering Consultants design specialised access systems and ramps. Our services include concept design, fabrication drawings, lasercut files, engineering certification and we can also assist with quality control and quality plans. Some examples of specialised access systems are given below:

The forklift ramps shown below are used for loading and unloading of food trucks. These ramps were fabricated by others some time ago and were never rated for a safe working load / engineered and thus needed to be certified for a specific capacity. An analysis of the Forklift and Access Ramp Design was done by Dynamic Engineering Consultants. It indicated that the ramps were indeed not fit for purpose as it did not comply with the relevant standards in relation to the required load rating. Dynamic Engineering recommended modifications to the ramps to ensure compliance and issued a design report based on the proposed modifications (certified the proposed design).

The revised and upgraded ramps are shown in the second picture below. The new design incorporated design improvements where required (upgraded pin connections and sleeves), and also included some safety recommendations (“keep-clear” areas added). Through our involvement in this project we were able to provide value to our client by: 1) Improve the existing design in terms of safety 2) Provide the required paperwork required by the mines safety inspector.

Process Improvements and Fault-finding

At Dynamic Engineering we understand that our clients are always pushing to improve productivity, whilst at the same time reducing maintenance related delays. After all, production is the name of the game. Dynamic Engineering can help with process improvements.

We also understand that sometimes plants have not been optimised and that a relatively small production bottleneck can make a big difference to the overall productivity of a process plant. We can help by improving throughput by resizing slurry pumps and piping systems – whilst still keeping impeller tip speeds low enough to achieve satisfactory wear rates.

We can perform detailed slurry or water pump calculations, design pump foundations / skids and provide a custom solution to your problem.
