The Benefits of Twin-Shaft Mixing | powderbulksolids.com

Jun 06, 2012 · A twin-shaft mixer can also accommodate small batches, expecting the same mixing performance and results. Concrete formulas with course aggregate sizes up to 7 in. can be processed. Scientific studies have confirmed that self-consolidating concrete (SCC) can also be processed within the same 30-sec mix time (Figure 3).

Stability Problems of Frequency-Converting Rotation

As a number of parameters significantly influence the concrete mixtures quality, the concrete fluidity impacts much on the production process and product quality. To improve the concrete mixtures quality, the concept of frequency-converting rotation is proposed based on the rotation driving dynamic characteristics of mixer. By analysing the phase-frequency characteristic of twin-shaft mixer's

An Experimental Study on the Compressive Dynamic

May 27, 2021 · An experimental study was conducted using a hydraulic servo machine to examine the compressive dynamic performance of rubber concrete under freeze-thaw cycles by considering 4 different numbers of freeze-thaw cycles and 8 different strain rates. The compressive stress-strain curves of rubber concrete under different loading conditions were obtained.

Mixing (process engineering) - Wikipedia

A great deal of engineering effort goes into designing and improving mixing processes. Mixing at industrial scale is done in batches (dynamic mixing), inline or with help of static mixers. Moving mixers are powered with electric motors that operate at standard speeds of 1800 or 1500 RPM, which is typically much faster than necessary.

Introduction. Foam concrete has been used as a filling material for crash barriers due to its good energy-absorbing performance. However, its significant disadvantages, including low strength, poor toughness, and easy cracking, may affect the structural performances and safety of crash barriers (Kearsley and Wainwright, 2001; Etkin et al., 2010; Kudyakov and Steshenko, 2015).
