Technical Field

The invention relates to the technical field of aggregate processing, in particular to a rotor of a recycled concrete aggregate mortar removing device, a device and a working method.

Background

In recent years, with the acceleration of industrialization and urbanization and the rapid development of the construction industry, the overmining of natural aggregate resources by people leads to the gradual reduction of natural aggregates, so that the attention degree of people on the protection of related natural resources is continuously improved, and the production of recycled aggregates by using waste garbage and other raw materials brought by the construction industry to prepare new concrete becomes an effective way for solving the problem of resource shortage; the quantity of Chinese construction waste accounts for more than one third of the total quantity of urban waste, the huge quantity of construction waste provides abundant resources for preparing aggregates required by new concrete, and the method is an effective way for saving resources and realizing waste utilization at present, but the recycled aggregates prepared by simply crushing waste concrete waste are not uniform in size, and the defects of more edges and corners, rough surface, large quantity of cement mortar which is not dropped and the like exist. The recycled concrete prepared by the recycled aggregate has large water content, low strength after hardening, low elastic modulus, and lower durability such as impermeability, frost resistance, carbonization resistance, shrinkage, creep and chloride ion permeability resistance than common concrete.

In order to improve the performance of recycled concrete, the low-quality recycled aggregate obtained by simple crushing needs to be subjected to strengthening treatment, namely, the performance of the aggregate is improved by improving the particle shape of the aggregate and removing hardened set cement attached to the surface of the recycled aggregate. In the prior art, a vertical crusher or a ball mill is often adopted to carry out strengthening treatment on recycled aggregate, the crusher is easy to cause secondary crushing of the aggregate, and the granularity of the aggregate is reduced and cannot meet the use requirement. The adoption of the ball mill can avoid the crushing of the aggregate and effectively remove the mortar on the surface of the aggregate, but the ball mill has low filling rate and large volume during the operation and cannot be carried on a vehicle. The recycling of concrete aggregate is often carried out on site, which limits its usefulness.
