Promote The Technology of Concrete Mixing Plant

<p>Tradi-tional recycling methods are based on compression rupture with the use of crushing and grinding systems but these methods have two main shortcomings: they are not selective regarding concrete composition and they induce an extensive destruction of the ma-trix and of the aggregates. Therefore, most of the recycling products are used as low-quality materials mainly for the construction of road bases we may use Twin-shaft Concrete Mixer while doing that. More-over <a href="http://www.concrete-batching-plants.org/concrete-batching-plants/small-concrete-batching-plants.html">mini mobile batching plant</a>, none of the current processes allows recovering and recycling the hardened cement paste.</p>Henan Daswell Machinery Co., Ltd,is a professional manufacturer and trader specializing in the research, development and production of construction machinery for nearly 30 years. Our main products are as follows:belt type <a href="http://www.dwmixers.com/products/concrete-batching-plant/stationary-concrete-batching-plant.html">concrete mixing plant</a>s,<a href="http://www.dwmixers.com">concrete batching plant</a>s,concrete mixer,blocking making machine,concrete pump,etc. <p> <p>As several experiments were performed on a horizontal single-shaft and a twin-shaft concrete mixer provided by Firma ELBA-Werk Maschinen GmbH. The volume of the single-shaft mixer according to Fig. 4 is V =60 L. The volume of the twin-shaft mixer according to Fig. 5 is V =120 L. The mixers have spiral mixing tools that move horizontally. It is characteristic of the twin-shaft mixer that the two mixing tools overlap in the middle part of mixing chamber. The mixing tools of the twin shaft mixer move in opposite directions towards each other. The product can be conveyed from the outer edge of the trough toward the interior or from the interior to the outer edge. In the single-shaft and twin-shaft mixer, the wall-mounted mixing tool has a diameter of DW =550 mm. The length to diameter ratio between the drum diameter and the length is DT/L &asymp;1 for the single-shaft mixer and about 2DT/L &asymp;2 for the twin-shaft mixer. The filling ratios &phi; were &phi;&asymp;50%. The rate per minute (rpm) for the single-shaft mixer n can be adjusted up to 75 rpm; for the twin-shaft mixer it is 49 rpm. A constant rpm of n =20 rpm is set for the performance of the mixing trials. In average mixing jobs, the mixing times are about tM &asymp;35 s according to.</p>
