The present invention relates to an aggregate manufacturing method and apparatus for producing high-quality aggregates from waste concrete stone powder (hereinafter referred to as "waste concrete stone powder") and stone powder produced by crushing concrete lumps and the like from Masatosa or construction waste, and more. In detail, the aggregate material such as Masatosa, waste concrete stone powder, and stone powder is crushed to a suitable particle size as aggregate, and then the moisture contained in the aggregate raw material is dried, and the stone powder, soil, dust, fine powder of the fine particles mixed in the aggregate raw material. It relates to an aggregate manufacturing method and apparatus for producing high quality aggregates by removing foreign substances such as.

In general, aggregates such as sand or gravel, which are used as concrete for construction, are mostly collected from rivers, rivers or the sea, washed with water, and produced by screening them by size, or crushed in recycling crushing sites of quarries or waste concrete. Aggregate is produced and used by work.

However, in recent years, the collection of aggregates in rivers and rivers has become a big problem due to the destruction of the natural environment and the depletion of resources. Also, the production of aggregates in quarries or waste concrete recycling crushing sites is caused by the excessive inclusion of stone powder and fine particles. The production of aggregates and fine aggregates was not only unreasonable, and the production of aggregates was not sufficient because the production of aggregates was not sufficient.

On the other hand, aggregates produced by recycling recycled concrete do not distribute evenly by particle size and contain large amounts of garbage and other foreign substances such as earth and sand fines, vinyl chips, wood chips, and tree roots. Was low and the absorption rate was high, so the quality of the aggregate could not be guaranteed.

Therefore, in recent years, various techniques for producing aggregates for producing aggregates from Masatosa or waste concrete powder and stone flour have been proposed in order to increase the quality and production of aggregates. However, aggregate raw materials such as Masatosa or waste concrete powder and stone flour have been proposed. Most of them contain a large amount of water, and also irregular particle size, as well as a large amount of mixed foreign matter, such as fine particles of stone powder, dust, fine powder was difficult to select the aggregate, and the production process was not efficient.

That is, the aggregate raw materials such as natural or wild Masatosa, waste concrete stone and stone powder are mostly irregular in particle size and contain a large amount of water by rainwater or sediment water that penetrates underground, so such moisture is aggregated from the aggregate raw material. The fine powder and fine particles and foreign matters are entangled together, and also attached to the net of the sorting machine in the sorting process, so that the sorting work is not efficiently performed and there are problems in that the aggregates, fines and foreign matters are not selected separately.

Therefore, in order to produce high-quality aggregates from aggregate materials such as Masatosa or waste concrete powder and stone powder, first, the aggregate raw material is crushed to an appropriate particle size, and then the moisture contained in the aggregate raw material is dried to remove it to some extent and then subjected to the selection process and the production process.

Aggregate material with a high specific gravity is guided to the outer edge of the picture and falls.

The air injection pipe 48 installed on the inner circumferential surface of the lower part of the separating cylinder 41 sprays high pressure air from the lower part to the upper part to scatter foreign matter having a small specific gravity to the upper part and separates it from the aggregate material having a large specific gravity. .

In the secondary separator 40 having such a configuration, aggregate raw material is introduced into the hopper 45 through the belt conveyor 31b in the primary separator dryer 30, and the blades are driven by the motor 45a in the hopper 45. The car 45b is rotated and the aggregate raw material is scattered into the upper center of the separation tube 41 through the input plate 45c, and the aggregate raw material scattered into the center is fed to the motor 42a and the pulley 42b at the center. By hitting the rotating blade 43 rotates at high speed, and scattered at the same time to the crushing groove 43c, segregation is removed, where the foreign matter having a small specific gravity is the rotary blade 43, the blowing blade 43b, and the air spray pipe Cyclone wind is generated by the blowing force of 48 and scattered to the upper part, and is sucked into the blower 46 through the exhaust pipe 46a, and is collected by the dust collector 47, and the aggregate material having a specific gravity is rotated by the rotary blade 43. Ride on the inner circumference of the guide holder 44 installed on the lower side toward the center Wing (43a) is fed up away.

The guide blade 44c attached to the inner circumferential surface of the separating cylinder 41 at the position of the rotary blade 43 mounted on the shaft 42 prevents the aggregate material from falling down on the inner circumferential surface of the separating cylinder 41. As a function, the aggregate raw material is guided to the inner side where the rotary blade 43 is located so that the aggregate raw material hits the rotary blade 43 and is scattered and segregation is removed.

Aggregate raw material collected in the center from the above put on the scattering wing 43a is bumped or struck by the scattering wing 43a and scattered on the rotary wing 43 located on the lower side, and is scattered again by the rotating wing 43.
