A concrete mixer is a specialized mechanical device that mixes cement, sand, gravel aggregates, and water (sometimes including additives) in a certain proportion to prepare a uniform concrete mixture.
Its core working principle is to fully mix different components through mechanical action to achieve the required uniformity and construction performance. According to structure and working method, concrete mixers can be divided into several types:
By mixing principle
Self-falling type: Materials are lifted as the mixing drum rotates and then fall by their own weight, suitable for plastic concrete.
Forced type: Materials are subjected to strong shearing and turnover by rotating blades, suitable for dry-hard or high-performance concrete.
By working nature
Batch type: Each batch of material is measured, mixed, and discharged separately, allowing more precise quality control.
Continuous type: Materials are continuously fed and discharged, with high production efficiency, suitable for large-scale projects.
By installation method
Stationary type: Used in concrete batching plants or mixing towers, with high stability.
Mobile type: Convenient for relocation, commonly used for medium, small, or temporary projects.
By discharge method
Tilting type: Materials are discharged by tilting the mixing drum, commonly seen in smaller equipment.
Non-tilting type: Materials are discharged through bottom or side outlets, mostly used in large or continuous operation equipment.
