Description

A special mixing equipment for recycled concrete preparation

technical field

The invention relates to the technical field of mixing equipment, in particular to a special mixing equipment for the preparation of recycled concrete.

Background technique

Recycled concrete means that waste concrete blocks are crushed, cleaned and graded, mixed with gradation in a certain proportion, partially or completely replaced by natural aggregates (mainly coarse aggregates) such as sand and gravel, and then added with cement, water, etc. The new concrete formed, because the recycled concrete aggregate usually includes a small amount of stones separated from the mortar, some stones wrapped in the mortar, and a small amount of cement mortar that is independently formed into blocks, and there are many types of aggregates. During the process, it is necessary to ensure that the recycled concrete aggregate is fully mixed with the natural aggregate, thereby ensuring the performance of the new concrete and enhancing its stability.
