JS Concrete mixer

The mixing speed and mixing time of the concrete mixer are two important factors that affect the performance of concrete. These two factors are directly related to the adequate mixing of various raw materials in concrete, thereby affecting the performance characteristics of concrete such as uniformity, strength and durability.

First of all, the mixing speed refers to the rotation speed of the concrete mixer during the mixing process. The mixing speed directly determines the collision and dispersion of various raw materials in concrete. A higher mixing speed helps to better mix cement, aggregate, sand and other raw materials evenly and promote better reaction. However, stirring at too high a speed may result in excessive shear forces, causing excessive wear and increased energy consumption. Therefore, when selecting the stirring speed, it is necessary to consider sufficient mixing while minimizing energy consumption and mechanical wear.

Secondly, mixing time refers to the residence time of concrete in the mixer. The length of mixing time is directly related to the uniformity and mixing quality of concrete. Adequate mixing time ensures that cement and other admixtures can fully react chemically, thereby improving the strength and durability of concrete. However, mixing for too long can cause the concrete to flow too much, leading to delamination and loss of some of the cement's effect. Therefore, in practical applications, the mixing time needs to be reasonably controlled according to the specific concrete type, mix ratio, and engineering requirements.

The mixing speed and mixing time need to be coordinated during the concrete mixing process. Appropriately increasing the mixing speed, combined with appropriate mixing time, can help achieve full mixing of various raw materials in concrete and improve the uniformity and performance of concrete. However, in actual operation, it needs to be adjusted according to the specific concrete mix ratio and engineering needs to balance the efficiency and quality of concrete mixing. Only through scientific and reasonable mixing parameter settings can we ensure that concrete reaches the strength, durability and stability required by the design.
