Mobile crushing plants are built ready-mounted on their own travel gear. Semi-mobile plants, on the other hand, are moved from one location to the next as a piggyback load on separate haul units. Each crushing plant comes ready to operate with its own feed hopper, feed conveyor, discharge conveyor and material transfer belt. The size and design of the crusher naturally depends upon the work that it is intended for.
Semi-mobile crushing plants are always to be recommended when a change of location in long periods is required in order to optimize the raw material transportation- and operational-costs of the quarry department.

What is frac sand? | American Geosciences Institute
Frac sand is a type of sand with small, uniform particles. It is injected into the rock formation along with the water used to fracture the rock in the process known as hydraulic fracturing ("fracking"). The sand is used to prop open the fractures that are created. Because the particles are uniform, fluids like water, oil, and gas are able to flow through the spaces between the particles.

Sand and Gravel Mining Industry
The sand and gravel settles out of the water and form the river bed. As the river channel moves across the landscape, the sand and gravel (aggregate) deposits are left behind. In the Platte River valley, these deposits can be greater than 150 feet deep and often contain mammoth bones and teeth, bison bones and petrified wood.
Sand: Product of the disintegration of rocks over long periods of time. Most sand casting operations use silica sand (SiO 2). A great advantage of sand in manufacturing applications is that sand is inexpensive. Another advantage of sand to manufacture products by metal casting processes, is that sand is very resistant to elevated temperatures.
