{PREHEATING DEVICE FOR AGGREGATE}

The present invention relates to a construction and civil engineering equipment, and more particularly, to an aggregate preheater that can preheat an aggregate material into an asphalt mixer while carrying it.

In general, as the means of transportation have developed, many roads have been constructed so that many transportation means can pass.

The above roads have been constructed of materials such as asphalt, cement and aggregate. Among them, the asphalt mixture in which a majority of the roads are mixed with the aggregate, the stone and the asphalt is preferably used in consideration of the traveling conditions of the transportation means.

Asphalt pavement using the above-mentioned asphalt mixture is broken in the common crack such as crack or port hole, and maintenance of various methods is carried out according to the scale of the damage in case of damage.

In particular, port halls are increasing due to frequent heavy rains in the summer and snow removal in winter due to the use of snow remover (calcium chloride), and urgent repair work will be carried out to prevent accidents when such port holes occur.

As a result, it is not possible to repair the ascon plant. However, in case of emergency repair work, temporary durability is relatively weak and expensive. We carry out repair work and perform repair work with heating asukon again.

In addition, despite the fact that waste asbestos generated during the repair work of the asbestos packaging is not recycled, it is used as a surface repair method due to the absence of indirect recycling equipment which does not cause secondary aging in the past It is not only wasted resources but also environmental pollution due to the small size, and thus there is a need for recycling waste asbestos.
