Hydromining: Faster, Safer Material Movement

NPE delivers complete hydromining packages from: Concept and design Installation and commissioning Operation and maintenance Monitoring and reporting Hydromining converts the product into a slurry by applying high-pressure water. Subsequently, NPE pumps the slurry via a pipeline to the desired location. Additionally, water flows from an external pressure source through 40-bar-rated rubber hoses, and the flow and pressure are controlled using interchangeable nozzles up to 58mm.

The NPE Hydromining tracked cannon serves as specialist equipment for this process. NPE manufactures this self-propelled machinery specifically for hydromining and pond-cleaning applications.

NPE’s hydromining techniques and slurry pumping capabilities include: 

• Tailings Recovery

Analysis

Step one in developing a power plan is to analyse your actual power requirements. This is achieved by reviewing the items and processes you wish to power and/or using load analysers to show what power is currently being used.

Once this information is obtained, a load analysis chart can be created showing the load behaviour of your application.

Comparison

Once the analysis is complete, the required generator size is established. From here, the available engines in these size ranges are compared on factors such as fuel economy, serviceability, and parts availability.

The Power Plan

Once sizing and engine selection are complete, a formal power plan can be developed to outline the steps needed to ensure the correct generator(s) are used to deliver the best overall value for the project.

NPE’s Atlas Copco QAC TwinPower™ Generators: Double the Flexibility, Twice the Power

One of the standout power assets in NPE’s fleet is the QAC TwinPower™ Generator Range: state-of-the-art equipment engineered to deliver maximum performance, maximum reliability, and maximum efficiency.

Fully loaded, the QAC TwinPower™ solves load-low issues and reduces fuel consumption and CO2 emissions by up to 40% in variable-load applications, thanks to the centralised control panel with an integrated Power Manager System that switches the two power packs on or off based on load requirements. The new QAC 1350 TwinPower™ is Stage V compliant and provides an environmentally friendly way to power operations, with nitrogen oxide (NOx) emissions reduced by 80%. With the two power packs in one platform, you have the flexibility you need. The QAC TwinPower™ can be used as a single unit, two different units, or as a prime and standby pair in the same box, with one unit operating at 50Hz and the other at 60Hz.

Key benefits of QAC TwinPower™

The QAC TwinPower™ is a 20ft ISO containerised unit housing two compact generators. This configuration, with its fast-paralleling system, allows the two generators to operate independently or in parallel, providing multiple solutions and combinations for prime and standby use.

In simple terms: it provides two independent generators in a single 20ft container, designed for operation in parallel or standalone modes, supporting both 50Hz and 60Hz frequencies with prime and standby capability.

For remote projects where uptime is everything, the built-in redundancy and efficiency can make a genuine difference to operational stability and cost control.
