The sandstone production is possible from two types of materials: from rocks (it is necessary to crush and mill the stones and classify them into the appropriate sizes to sell) and from natural fine material (placers, soils etc.). In this case, it is necessary to concentrate the sand (washing the clays), then classifying (after drying) to sell.

Other rocks are worn down, producing sediment, which is deposited somewhere - eg sea floor, desert...
The sediment may then be buried under more sediment - it gets compacted, and may undergo mineralogical changes - eg the growth of a mineral cement - rock fragments may be squashed, and form a matrix which supports the other grains (such as feldspar and quartz...) OK that's VERY brief sorry, I'm not really into sed rocks that much! Hopefully someone else would've given you a way better explanation by the time I've clicked submit...
The basic idea of it though is: erosion - transport - deposition - compaction & diagenesis....
