A type of adjustable spiral blade concrete mixer Technical Field

[0001] This utility model belongs to the technical field of concrete mixers, specifically a spiral blade adjustable concrete mixer. Background Technology

[0002] With the development of the construction industry, concrete has become a standard building material. Concrete mixers can fully mix raw materials such as cement, sand and gravel aggregates and water according to a certain mix ratio, so that the components are evenly distributed, achieving macroscopic and microscopic homogeneity and ensuring the stable quality of concrete.

[0003] Concrete mixers can also break down the initial hydration film coating on the surface of cement particles, promoting the bonding of cement particles with other materials to form ideal hydration products, thereby improving the strength and durability of concrete.
