Sand production is a problem that affects hydrocarbon production from unconsolidated sandstone reservoirs. Several factors, such as the strength of the reservoir, its lithification and cementation and reduction in pore pressure, may cause sand to be separated from the rock and transported by hydrocarbons to the well. Producing …

But to house those people, industrial sand mining or aggregate extraction – where sand and gravel are removed from river beds, lakes, the oceans and beaches for use in construction – is happening at a rate faster than the materials can be renewed.
He sells the sand to other contractors as well. In lakes, this size mechanical excavation equipment like draglines, trackhoes, etc., have limited reach. Mining with scrapers and dozers requires dewatering around-the-clock to keep the water table down so that the machinery can excavate, which is a labor intensive, costly method.

A sand classifying tank is a type of mineral processing equipment. It works by separating sand particles according to their specific gravity, which means easier removal of the grain sizes you don't need for your operation. The tank consists of a series of closely spaced, perforated screens or plates arranged in an inclined position.
