Static vs. Mobile Mixers

Pre Blend Mixers are batching plants that are always ready to work. You can set up your mixer on-site to work only when you want it to. Our Pre Blend Mixers can also be mounted on a carrier for full mobility. A static mixer has its own power unit, whereas a mobile mixer will receive its power from the carrier.

Why choose wet over dry?

Wet and dry shotcrete both have their purposes. However, the advantages of wet shotcrete over dry shotcrete are hard to ignore. Here are some of the common reasons that wet is chosen over dry:

1. Higher Production Rate
Wet shotcrete is able to be produced at a much faster rate which means less manpower is needed for the same amount of work.

2. Less Rebound/Waste
When using wet concrete there is less rebound so worrying about wasted mix falling to floor is no longer a concern.

3. Less Dust
Being able to operate the shotcrete machine without the particles in the air is a major advantage to the nozzleman.

4. Concrete Specifications Changed On-Site
By providing the wet concrete, one can change the concrete specs in a way that is fast and easy.

Pre Blend Mixer vs. Drum Mixer

Knowing that concrete is a key component in the mining industry, it is important that we are using the best quality concrete we can, with the best return on investment. There are many reasons that volumetric mixers supersede the drum mixers:

1. Cost Reduction
Cost of producing your own concrete from raw materials can drop as much as 20-40%.

2. Consistency and Flexibility
Pre Blend Mixers have a precise measuring system to ensure a consistent mix. This mix can be changed on-site depending on your purpose and conditions.

3. No Waste
You never have to worry about a wasted load as the materials are kept separate Drum mixers have a time expiration. If any equipment breaks down, the concrete doesn’t go to waste with a Pre Blend Mixers. With Pre Blend Mixers there is also the advantage of producing only what you need. No more excess concrete and no more short loads.

4. Control your Schedule
A Pre Blend Mixer means that workers aren’t waiting for the drum mixer. But rather, have full control over your schedule.
