Sand extraction through mobile processing
The flowsheet (Fig. 5) to the sand processing plant from Figure 4 contains only the essentials for producing sand from gravel. After feeding, the material flow is taken from a small storage container by means of a weigh feeder and transported to the plant. To protect the mill, larger metal particles are separated along the way. In this configuration, an energetically efficient rotor impact

How to Make Gravel and Sand
The processing of extensive pit run gravel in many instances employs a permanent or semi-permanent plant installation with a flexible system for movement of feed. The plant must be designed to produce a variety of product sizes and be capable of changing and blending products to meet varying customer specifications or to compensate for variations in the pit conditions.

3. The Environmental Impacts of Aggregate Extraction
This process has many significant environmental impacts. [1] Creating the pits or quarries requires the removal of virtually all natural vegetation, top soil and subsoil to reach the aggregate underneath. Not only does this lead to a loss of existing animal wildlife, it also leads to a huge loss of biodiversity as plants and aquatic habitats

Sand and gravel processing
If the sand was to be used for glass-making, as foundry sand, or in other processes, then the quarry might need to wash the sand in acid to remove contaminants, such as iron. The processing plant would probably consist of a screening and grading plant (probably an elevated corrugated structure, with clearance for wagons/ lorries to pass underneath) and a storage area, with discrete areas for

Process & Product
First, the raw sand is placed on the conveyor. The dirt, clay and large rocks are sorted out and removed from processing. This dirt and clay is unsaleable. Second, the rock and pea gravel are sized and put into a washer and cleaned together then re-sorted by size. The washed rock is 7/16″ to 1.25″ and is used for gravel roads and drive ways.

Sand Extraction: 1. Introduction
This sand and gravel are mined world-wide and account for the largest volume of solid material extracted globally and the highest volume of raw material used on earth after water (about 70-80% of the 50 billion tons material mined/year). Formed by erosive processes over thousands of years, they are now being extracted at a rate far greater than their renewal.
