The aggregate or aggregates, are essential raw materials used in the production of concrete and construction materials. 

In this article, we explain how they are produced.

Step 1: extraction

The extraction of materials alluvial can be made with the help of a charger or excavatorif the area is dry. If the area contains watera dredger is connected to the floating conveyor. From a tour, or from the massive rocks, the extraction requires the use of explosives. The blasting it breaks down the materials, which are then brought into a structure handling.

Step 2: transfer

The transfer aggregate plants handling it is generally carried out by conveyor tape. This reduces the cost of transportation. When the conveyors are not feasible, the transfers are carried out by truck.

Step 3: management

The aggregates are reduced in size by crushing. Are then sorted using screens to network metal. Then the aggregates are often washedas some uses require that the material is perfectly clean.

Step 4: Storage

The materials are preserved in batteriesin baskets or siloswhere are sorted according to different categories: there are sands, gravel and rocks of various sizes. Each category of the aggregate meets specific criteria based on the intended use.

Step 5: loading and weighing

All the materials are weighed with scales to truck.

Step 6: transport

Delivery is carried out by truck.

Gmp spa is the manager authorized the collection and transport of this type of waste, as well as many others, and ensure the correct transport to the point authorizedwhere it will be made of the appropriate management of inert wastein accordance with the legislation in force and with the guarantee of a minimum impact on the environment. In our stabilimeto of Collazzonewith the recent refurbishment completed in the year 2011, has been installed a new system of screening five floorswith the storage of finished material in the hopper. This system allows the selection of five different sizes of gravel and a thorough washing of the same.
