Mining

Through our experience in the mining field we understand and act on the additional safety,  reliability and maintainability requirements for mining related projects. Whether you are reviewing your standards, designing a new facility or even if you are already operating and are planning improvement projects – we can help.

Dump truck ramp

Dump trucks are large and heavy vehicles and thus require very sturdy maintenance ramps. In addition, our client needs to be able to move the ramps easily. Dynamic Engineering designed the ramps, which fulfil both requirements. The ramp was designed in accordance with the Australian Standards and was made strong enough to withstand the load of the truck. The ramp can simply be moved with a forklift. It includes sleeves to prevent the forklift guides from damaging the ramp structure.

Hopper

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.

Project Management and Expansion Projects

Dynamic Engineering Consultants has wide experience with project management and can assist you with your small to medium projects. 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:

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:

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.

Access Platform Design

Sometimes mining operations require tailor made engineering solutions due to space and operational constraints. Below is an example where Dynamic Engineering provided designs for such an access platform extension. The platform is suspended from the “back” of the portal and is furthermore connected to an existing platform.

Portable Steel Platform Design

Dynamic Engineering Consultants Pty Ltd has completed several portable steel platform designs, which are used for inspections. These platforms are used in the mining industry to inspect, amongst others, excavator buckets and truck trays. The platforms are moved into position with a forklift and are then adjusted and levelled by means of adjustable jacks.

This specific design is certified for 500kg load but can be tailored to the client’s requirements.
