High mixing efficiency
Fast mixing speed: The two mixing shafts of the twin-shaft mixer rotate in opposite directions, driving the mixing blades to quickly turn over the materials. Compared with the self-falling mixer, which relies on the self-weight of the materials to fall for mixing, the active mixing mode of the twin-shaft mixer enables the materials to be fully mixed in a short time, greatly shortening the mixing cycle. For example, in large concrete mixing plants, the mixing capacity of the twin-shaft mixer can reach hundreds of cubic meters per hour, meeting the high-intensity production requirements.
Strong continuous operation ability: Its structural design allows materials to continuously enter and exit, enabling continuous production. In scenarios such as road construction that require a large amount of continuous concrete supply, it can continuously and stably provide well-mixed concrete to ensure the construction progress. However, self-falling mixers often need to pause during the feeding and discharging processes, affecting the overall operation efficiency.
Good mixing quality
High mixing uniformity: The blades on the two mixing shafts cooperate with each other, forming a complex material flow during the mixing process, enabling the materials to be fully mixed in all directions. Whether it is solid materials such as cement and aggregates, or liquid materials such as water and admixtures, they can be uniformly mixed, effectively avoiding the segregation of concrete. Through testing, the coefficient of variation of the homogeneity of the concrete mixed by the twin-shaft mixer is far lower than the industry standard, ensuring consistent performance of all parts of the concrete.
Strong adaptability to materials: It can mix various types of materials, including plastic concrete, dry hard concrete, lightweight aggregate concrete, etc. For dry hard concrete, which is difficult to mix evenly, the twin-shaft mixer can also achieve a good mixing effect with its powerful mixing ability, while some other types of mixers may not mix such materials thoroughly.
Advantages in energy consumption and maintenance
Remarkable energy-saving effect: The advanced mixing principle and reasonable structural design enable the twin-shaft mixer to achieve high-efficiency mixing while having relatively low energy consumption. Compared with some old-fashioned mixers, when completing the same mixing task, the twin-shaft mixer can save 10% - 20% of electricity consumption. Long-term use can reduce the operating costs for enterprises.
Low maintenance cost: The structure is relatively simple, and key components such as mixing shafts and blades are easy to disassemble and replace. Moreover, the service life of these components is relatively long, reducing the cost of frequent component replacement and downtime. At the same time, daily maintenance work is also relatively convenient. Operators can perform routine maintenance and inspections after simple training, reducing the labor cost of maintenance.
Wide range of applications
Strong adaptability to project scale: There are various specifications and models available, ranging from small equipment suitable for rural housing construction and small-scale decoration projects to large equipment used in the construction of large-scale infrastructure such as high-rise buildings, bridges, and dams. Whether it is the requirement for equipment flexibility and economy in small projects or the demand for high output and high quality in large projects, the twin-shaft mixer can meet them.
Good site adaptability: Its compact structural design allows it to be well installed and used under different site conditions. In some urban construction sites with limited space or in complex terrains in the wild, the twin-shaft mixer can be flexibly arranged, while some large self-falling mixers may be restricted due to their large volume and high requirements for the site.
