What we have learnt
- Free fall and power mixers are the two main categories of concrete mixers.
- Pan and trough mixers offer distinct advantages in terms of mixing efficiency and productivity.
- Optimal mixing duration is crucial for ensuring the quality and workability of concrete.
Key Concepts
- -- Free Fall Mixer
- A type of mixer where materials fall into the drum and are mixed by gravity.
- -- Power Mixer
- A mixer that relies on rapid rotation of paddles for efficient and homogeneous mixing, suitable for stiff and cohesive mixes.
- -- Pan Mixer
- A mixer with a pan-shaped drum and vertical shaft with paddles, designed to prevent material sticking and ensure thorough mixing.
- -- Trough Mixer
- A mixer that uses a horizontal trough-shaped drum and can have single or double shafts for optimal mixing.
- -- Mixing Duration
- The time required for mixing materials to achieve a homogeneous mixture, which varies based on mixer type and capacity.
- -- Batch Production
- The process of producing concrete in batches, affected by the size of the batch and the cycle time of the mixer.
