How to select a reasonable mini concrete pump

<p>Concrete mixing kinematics have been highlighted for an ultra high performance self-compacting <a href="http://www.dwdieselmixer.com/">concrete mixer</a>(UHPSCC). The hard-to-mix nature of this concrete, which features a greatly expanded mixing time scale, facilitates both visual and power observations. The components are mixed in a 20-liter <a href="http://www.dwconstructionmachine.com/en/Products/Concrete_Batching_Plant/25.html">concrete mixing plant</a>, twin-shaft concrete mixer filled to a nominal level. The mix design is defined by: a water-to-fines ratio of 0.15, high-range water reducer admixture (HRWRA) proportioned at powder adsorption saturation (plateau of the adsorption isotherm), with powder composed of white cement (900 kg/m3) and silica fume (300 kg/m3), and the remaining solid particles composed of 0&ndash;1 mm sand. After 90 s of dry mixing of the solid components, premixed water and HRWRA are loaded at a constant flow rate during an additional 30 s. The origin of the mixing time is set at the beginning of liquid loading.</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.

The concrete mixerpower consumption measured during this test is given in Fig. 2, which also indicates the points corresponding to the six mixing states from Fig. 1. The filtered power consumption profile is associated with a measurement of power fluctuation vs. time. This fluctuation is measured herein by the difference between two successive power consumption measurements <a href="http://www.dwmixers.com/products/concrete-batching-plant/portable-concrete-batching-plant.html">batching plant</a>, in absolute value terms. The time interval between measurements is 0.1 s. The figure depicts the maximum of this difference during the 3 last seconds of measurement before indicated time.</p>
