The company PRDM Trakt Sp. z o.o. was looking for a new concrete mixing plant that would be making concrete for their own needs. Trakt decided to buy Mini Cobra C40, which has hourly capacity that matched company's requirements.
Features of the Cobra C80 mobile concrete mixing plant:
- Countercurrent planetary mixer
- "Flying" aggregate dosing and weighing system
- High pressure washout system for the mixer
- Aggregate moisture measuring
- Separate dust-free room for electrical cabinet
- Cement scale with a separate filter
Mixing concrete for more than 1100 windmills of Europe’s biggest wind farm is no small task. Tecwill Oy decided to use in a twin-shaft batch mixer from BHS-Sonthofen in COBRA concrete plant delivered to project. The mixer produces three cubic meters of fiber concrete per batch and allows for casting up to three windmill bases per day. With the right plant and mixer, it’s possible to produce concrete reliably and the effectively.
In clothing stores, my purchase decision is often related to the offer, "buy two, pay one”. Unfortunately, this applies rarely in concrete plant markets.
The impact of the COVID-19 pandemic increases new challenges and raises questions. What kind of impact this crisis brings to the concrete plant deliveries and installation? Is it possible to install and start-up the concrete plant during this crisis, stay on the schedule and still pay attention to safety of the employees? Now we will compare different type of concrete plants and their suitability for this exceptional period.
In June 2019 Tecwill Oy delivered Cobra C120 mobile concrete batching plant to Northern Sweden for a wind turbine projects. The first part of project includes 179 windmills, second one 440 windmills. The total project scope is estimated to be more than 1100 windmills, so it will be one of the biggest windmill parks in the World.
After using SUPER COBRA C120 for two years PPMD Kruszbet SA has decided to extend their production concrete activities. Having a great experience with Tecwill equipment was the key factor in the decision making process of purchasing the new plant. Kruszbet decided to order the second “twin” plant model to one of their aggregate mines located only 40 km far from the first Super Cobra.
Admixtures play an important role when it comes to the fine-tuning of the concrete production process. Admixtures are chemical, usually liquid, pumpable substances that, compared to other raw materials of concrete, are dosed and weighed in small amounts only, mostly just a few kilos per cubic meter. Concrete admixtures for instance are used to modify of the concrete consistency, to add small air bubbles for increasing the frost resistance and to accelerate the concrete hardening process. Admixtures though, to a very high percentage, consist of water.
High strength concrete not only allows to build filigree, slender constructions, but also to save cement and reduce carbon dioxide emissions.
