Description

Technical Field

[0001] The invention relates to the technical field of recycling ecological engineering components, and in particular to a recycled aggregate grinder for ecological engineering components. Background Art

[0002] Aggregates prepared from waste concrete are called recycled fine aggregates. The production process of recycled fine aggregates is mainly divided into four steps: 1. Sorting, removing impurities such as wood and glass from concrete through manual or mechanical equipment; 2. Crushing, crushing the concrete multiple times through a crusher to break the concrete into about 40 mm; 3. Strengthening, using physical strengthening technology to make the initially crushed concrete stone particles rotate at high speed in the strengthening treatment equipment, so that the aggregate particles accelerate friction and collision, so that the cement slurry and mortar attached to the surface of the aggregate can be removed, thereby improving the performance. After crushing, cleaning and grading, they are mixed in a certain proportion, and then cement, water and other ingredients are added to form new concrete.

When the device processes the concrete blocks, the metal reinforcements inside the concrete blocks will be introduced into the interior of the grinding assembly along the conveyor belt.

The waste concrete blocks that have been crushed are introduced into the interior of the outer shell 28 through the third conveyor belt 11, and are roughly ground by the outer shell 28. When the roughly ground waste concrete blocks are introduced into the interior of the movable cover 31 through the feed hopper 32, the second drive motor is started to drive the second drive gear 34 to rotate, so that the first drive bevel gear 37 is rotated, so that the movable cover 31 can rotate, and the threaded groove is matched to enable displacement, and the third drive motor is started to drive the second drive bevel gear 38 to rotate, so that the first drive bevel gear 37 can rotate, The eccentric shaft 36 is driven to rotate, so that the grinding block 35 can rotate eccentrically, and the grinding block 35 can perform fine grinding on the concrete stone particles, so that the mud or mortar on the surface of the concrete stone particles can be better removed, thereby obtaining reinforced concrete stone particles.
