Types of concrete mixer machines
Types of concrete mixer machines have batch mixers and continuous mixers, portable concrete mixer and stationary cement mixer, twin-shaft mixer and single shaft mixer and so on.
According to concrete mixing method, we can understand that the mixing energy, mixer working principle, hybrid method and other method can improve cement mixer efficiency.
About cement mixers
The type of mixer, the mixing cycle as defined by the duration, the loading method, and the energy of mixing. There are two main types of mixers: batch and continuous.
Abstract concrete mixers features and differences
In each type there are several configurations. The efficiency of a mixer is determined by the homogeneity of the concrete produced. It could also be considered as being determined by the energy used in producing a given quantity of concrete of the required homogeneity. This homogeneity is either measured by the composition of the concrete or by the variation of the macroscopic properties, such as compressive strength and workability. It is not clear that the variation of macroscopic properties is very sensitive to variation of composition or to inhomogeneity in the concrete produced. Therefore, a direct measure of the homogeneity of the concrete produced should be the most reliable method for characterizing a mixer. A direct measurement of homogeneity relies on the determination of the concrete composition, such as distribution of the various constituents, including air content, present in various samples taken during the concrete discharge. This composition method was recommended for standardization by RILEM [Efficiency of concrete mixers; report: efficiency of concrete mixers towards qualification of mixers].
The mixing energy is the product of the power consumption and the duration of the mixing cycle. It is not necessarily a measure of the quality of a mixer but is used for monitoring workability during mixing, avoiding the necessity of discharging the concrete to measure slump [Standard test method for slump of hydraulic cement concrete]. The literature does not report problems with the mixers commercially available today. The main innovations that are currently being worked on relate to producing mixers that reduce energy consumption and the time of mixing without affecting the quality of the concrete produced.
