Description
Technical field
This utility model is related to a kind of lightweight aggregate cement concrete mixing device.
Background technology
With the development of Building technology, the application of all kinds of lightweight aggregate cement concretes is increasingly extensive.But existing light bone
Adopting single blender material cement concrete mixing apparatus, it is not only difficult to be sufficiently complete the flocculation stirring process of cement more, and
And because lightweight aggregate cement concrete uses fine aggregate, and lacking hard coarse aggregate, the process of mixing and stirring can not be sufficiently complete
Cement mortar is mixed with the uniform of lightweight aggregate.Therefore provide a kind of by polytype and different stirring mixing velocity combination unit altogether
With constitute, can the not conglomeration of middle cement and lightweight aggregate be uniformly dispersed and that granule is complete is light after the completion of mixed process and preparation
Aggregate cement concrete mixing device oneself become when business urgently.
Utility model content
In order to overcome existing lightweight aggregate cement concrete mixing apparatus to be easily caused cement knot using the blender of single type
Group, lightweight aggregate crush and the shortcoming uneven with cement mixing, and this utility model provides one kind to combine using polytype mixing
Device and stir mixing velocity and reduce the lightweight aggregate cement concrete mixing device of change successively, it has can be so that cement not be tied
Group, lightweight aggregate do not crush, lightweight aggregate and the uniform advantage of cement mixing.
