Arenas Silíceas Gómez Vallejo - Laboratory
In our laboratories we carry out inspection and control tasks (granulometric tests, moisture, clays, etc.) of the incoming raw materials, as well as throughout the different stages of the production process.
The laboratory manager is responsible for receiving the samples, checking their state and identifying their properties or reference. s of the production process.
The laboratory manager refers to the product specifications and compares the results obtained in order to determine the composition of the products examined. ess.
Extraction: this is the first phase of our production process when the silica is first treated and suitable machinery is used to:
- Dismount silica sand.
- Uproot silica sand.
- Screen silica sand.
- Stockpile silica sand.
- Subsequent delivery to the silica sand factory.
Washing: this is the second phase of our production process when we use 2 washing plants that can be operated simultaneously or separately.
During the washing phase we use: clean water coming from our decanting basins which has been purified and treated; hydrocyclones; classification trommel screens which help to remove the existing clays and organic matter from the raw minerals which come from our quarries. Each product that has been washed and classified using a wet method is stored in the various stockpiles, perfectly identified, and awaits to be transported during the following phase of the process.
Drying: this is the third phase of the production phase when we dry the silica. We currently have 3 independent drying plants. The overall capacity of our dried material fluctuates between 40 and 50 Tm/hour. Dry processing of the sand allows us to obtain the different granulometric curves requested by our customers with the help of screening belts and trommel screens.
Packaging: this is the fourth phase of the production phase when the different wet and dry products of various granulometric curves are packaged.We currently have 3 manual packaging lines and one that functions automatically. The overall production capacity reaches 2,000 bags/hour.
Transport: the final phase of our process is the distribution of the final products in line with our customers' orders. We can facilitate different ways of delivery:
- Bulk transport of silica sand: lorries, tankers or dump trucks.
- Packaged and palletised silica sand.
- Big-bag for bulk transport of silica sand.
- Containers for bulk transport of silica sand.
- Platforms for bulk transport of silica sand, etc.
We have our own laboratory for conducting inspection and control tasks of silica sand. Find out more about us and check the quality of our products!
