Description

Technical Field

[0001] This utility model belongs to the field of recycled concrete production technology, specifically relating to a recycled concrete batching machine. Background Technology

[0002] Recycled concrete refers to new concrete made by crushing and grading waste concrete blocks, mixing them with graded aggregates in a certain proportion, partially or completely replacing natural aggregates such as sand and gravel (mainly coarse aggregates), and then adding cement, water, etc. The preparation of recycled concrete is generally accomplished by recycled concrete batching equipment.

[0003] Currently, existing recycled concrete batching machines generate a large amount of dust when crushing recycled concrete. Most batching machines do not have dust collection capabilities, causing dust to be raised and dispersed in the surrounding environment, polluting the air and affecting the health of workers. Therefore, we propose a recycled concrete batching machine. Utility Model Content
