Aug 17, 2018 Using recycled stone can save the water, energy, and other resources used to generate new building products from raw material sources. Recycled marble and granite are frequently used to make paving stones, fire pits, and mosaic tile, offering plenty of opportunities to make the most of what the Earth has provided.
Crushed stone aggregates are produced by crushing quarried rock, then screening it to sizes appropriate for the intended use. Production of crushed stone has three stages: Primary crushing to break down the stone to a manageable size; secondary and tertiary crushing to render the rocks into sizes specific to their applications; and screening to separate the crushed stone for further processing ...
product may therefore vary from one batch production to another depending on the raw materials used, mixing ratio of resin, quality of resin and other pigments and type of machinery employed for the production.
