FAQ
Q: What are the main advantages of twin shaft mixers over single shaft or planetary mixers?
A: Higher Mixing Efficiency: Dual-shaft counter-current motion generates strong shearing force, completing mixing cycles 30%–50% faster than single-shaft models. Superior Homogeneity: Achieves optimum concrete uniformity in a very short time, ideal for high-strength and self-compacting concrete. Balanced Wear Distribution: Material circulates continuously between the two shafts, minimizing localized wear on liner plates and blades.
Q: How is water and chemical admixture distributed inside the twin shaft mixing drum?
A: : To ensure rapid hydration and prevent cement balling, modern twin shaft mixers utilize a pressurized multi-nozzle spray bar manifold. Water and liquid admixtures are sprayed under pressure across the entire length of both shafts during the dry-mixing stage, accelerating wet mixing homogeneity by 20%–30%.
Q: How long is a standard mixing cycle for concrete batching plants?
A: A typical mixing cycle ranges from 45 to 75 seconds (including dry aggregate loading, water/additive injection, wet mixing, and discharging). The exact time depends on the concrete formulation and required slump level.
Q: How do twin shaft mixers prevent concrete buildup and "sticking" on internal walls?
A:Concrete adhesion is minimized through three engineering solutions:
High-Speed Counter-Current Air Currents: The aerodynamic flow generated by synchronized blade rotation reduces stagnant material zones.
Polyurethane or Chrome-Alloy Scraper Blades: End-wall clearance is kept below $3\text{mm}$ to continuously wipe internal surfaces clean.
High-Pressure Washout Systems (Optional): Automatic $360^\circ$ rotating high-pressure water nozzles integrated into the top cover for rapid end-of-shift cleaning.
