The main raw material for the cement plant is the limestone and the
"Paper" might be a misleading term regarding this context because paper is associated with trees, wood and cellulose. Stone Paper, or Rock Paper, as being the product made out of the so-called limestone flour, does not contain any cellulose! Shortly: Stone paper is not paper, but consists of up to 80% limestone and 20% additives.
Lime is made from indigenous limestone or chalk rock, one of the most abundant materials in the Earth's crust. Limestone and chalk are both sedimentary rocks and are chemically known as calcium carbonate. When crushed or ground, they are widely used as aggregates and building products. As a raw material, calcium carbonate can also be processed […]
The limestone sand-making plant process mainly includes three stages: coarse crushing, fine crushing, and sand making. The finished sand and gravel aggregate made of limestone can provide industrial raw materials for industries such as airport construction, water conservancy power stations, tall buildings, concrete mixing plants, etc.
