Detailed introduction:

Mixing plant composition

Concrete mixing plantIt mainly consists of material storage system, material weighing system and materialConveying systemMixing systemPowder storage system, powder conveying system, powder metering system, water andadmixtureThe metrology system and control system are composed of five major systems and other ancillary facilities。

Mixer main engine

Concrete mixing plant

Mixing machine according to its mixing mode is divided into forced mixing and self-falling mixing。Forced mixerIt is the mainstream used in mixing stations at home and abroad, and it can mix a variety of concrete such as fluidity, semi-dry rigidity and dry rigidity。The self-falling mixing machine mainly mixes liquid concrete, which is rarely used in mixing stations。

Force typeagitatorAccording to the structure, it is divided into spindle planetary mixer, single horizontal shaft mixer and double horizontal shaft mixer。Among them, the double horizontal shaft forced mixer has good comprehensive performance。

Weighing system

The material weighing system isThe key components that affect the quality of concrete and the cost of concrete production are mainly divided into three parts: aggregate weighing, powder weighing and liquid weighing。Under normal circumstances, the mixing station below 20 cubic meters per hour adopts the superposition weighing method, that is, the aggregate (sand, stone) is weighed with a scale, the cement and fly ash are weighed with a scale, the water and the liquid admixture are respectively weighed, and then the liquid admixture is put into the water weighing bucket before mixing。In the mixing station of more than 50 cubic meters per hour, the method of independent weighing of each material is used, and all weighing is controlled by electronic scales and computers。The weighing accuracy of aggregate is ±2%, the weighing accuracy of cement, powder, water and admixture is ±1%。
