Is It Valuable to Choose Twin Shaft Mixer and Portable Cement Silo
Dec 08, 2025
Twin shaft concrete mixer
Under the traditional single-shaft equipment, the twin shaft mixer, with its structural advantage of simultaneous twin-shaft mixing, have become the preferred choice for medium to large-scale projects. Their purchase value is not merely theoretical, but built upon long-term stable performance output and cost control.
Equipment lifespan is a core indicator of purchase value, and twin-shaft mixers excel in this regard. High-quality equipment uses high-strength alloy materials for the mixing shaft, treated with a wear-resistant coating, and the blades are made of impact-resistant high-manganese steel. Combined with a shaft end structure with excellent sealing performance, this effectively reduces material wear and dust erosion.
Under the premise of standardized operation and regular maintenance, Haomei twin-shaft mixers can have a service life of 8-12 years. Some core components can even be replaced to extend the equipment's value, far exceeding the service life of short-term rentals.
The application value of twin-shaft mixers is reflected in three core advantages: high efficiency, uniformity, and flexibility. The counter-rotating shafts create a strong convection mixing effect, improving the uniformity of concrete mixing by 15%-20% and preventing quality problems caused by uneven mixing.
The mixing speed is approximately 30% faster than single-shaft equipment, with an hourly output of 50-200 cubic meters, meeting the continuous supply needs of large-scale projects such as bridges, tunnels, and high-rise buildings. Furthermore, it is highly adaptable to various materials, stably mixing ordinary concrete, dry-hard concrete, and specialty concrete with admixtures.
For teams undertaking long-term projects, owning their own equipment allows for flexible scheduling according to the construction progress, without being restricted by the availability of rented equipment. This directly avoids downtime losses due to equipment shortages, especially during tight deadlines.
The resale value of twin-shaft mixers is also noteworthy. Due to their stable core structure, even after years of use, they can still function normally after refurbishment and repair, resulting in strong demand in the used equipment market.
Generally, equipment used for less than 5 years, if well-maintained, can retain 40%-60% of its original price as a secondhand asset; even equipment used for more than 8 years can still be transferred for 15%-25% of the original price. For engineering teams, when equipment no longer meets current project needs, reselling it can recover some costs, further reducing the risk of initial investment.
Cement Silos
The lifespan of cement silos mainly depends on the materials and manufacturing process. High-quality cement silos are welded from Q235B steel plates, with the portable cement silo body treated for corrosion and rust removal. They are equipped with rain caps and dust collection devices on top, and moisture-proof unloading valves at the bottom, effectively resisting the erosion of wind, rain, and humidity.
Under normal use, cement silos can last 10-15 years with extremely low maintenance costs. Only periodic checks of sealing performance and cleaning of residual materials are required. A one-time purchase can guarantee long-term material storage needs.
The application value of cement silos lies in three aspects: ensuring supply, reducing losses, and controlling quality. First, owning cement silos allows for sufficient material reserves to meet project needs, preventing production interruptions due to untimely supply of raw materials like cement. This is especially beneficial in remote construction sites with poor transportation, where advance storage significantly improves construction efficiency.
Second, the sealed storage method of cement silos effectively reduces material loss due to moisture, clumping, and dust. Statistics show that the material loss rate using cement silos can be controlled below 1%, while the loss rate of traditional open-air storage is as high as 5%-8%. Over the long term, this results in considerable savings in raw material costs. Furthermore, sealed storage prevents material contamination, ensuring the stability of concrete quality.
The secondary market for cement silos is also active. Due to their simple structure and slow wear, used equipment is readily accepted. Whether small engineering teams purchase used cement silos to reduce initial investment or large enterprises sell their old silos after upgrading equipment, buyers can be found quickly.
Generally, cement silos used for less than 6 years can fetch 30%-50% of their original price. Even silos used for more than 10 years, as long as the silo body is not severely deformed or corroded, can still be sold as temporary storage, with a residual value far exceeding that of some small-scale engineering equipment.
