What is involved in aggregated production?

The aggregate is the name of sand, gravel, crushed stone and similar objects used as building materials. The aggregate is used to produce asphalt, cement and concrete and is also used to check erosion, water cleaning and check emissions for electric power plants. The production of paints, glass, glass and paper is also necessary for the production of paints, glass, plastic and paper. Aggregated production usually requires natural materials to be mined from the ground or from water, crushed, sometimes crushed and transported for sale. Recycled aggregated production mainly uses materials rescued from old buildings and roads that have been replaced. The recycling unit can be cost -effective, in many cases that allows recycled material to compete with the newly manufactured freight material or sea bed for the production of the unit. Stone or rock aggregate usually comes from special surface quarries where the rock is blasting into large boulders or pieces, and then crushed to smaller pieceswhose. Some operations use the first crushing crusher because it can upgrade poor quality materials and facilitate removal of reinforcement from recycled materials.

After the first crushing, the material moves through a truck or a rock conveyor into a device to be processed into the final sizes with a cone shredder or an impact crusher. Once the material is size, it can be sent via an aggregated pad to remove clay and other undesirable materials. Machines used to remove unwanted materials include a protocol pad, a heavy media separator and a wear mill. These procedures are used to improve the quality of the aggregated dose to meet the required quality standards.

Screening is used to remove unwanted materials and is also used to evaluate doses. In screening, aggregated batch passes through screens with specific size holes and may or nevleather to be washed. Washing removes clay and other undesirable materials and also removes particles that are not the right size.

The aggregate is sorted by particle size and different sizes are required for different uses. Aggregated lots are stored separately during and after processing, so the final product is not contaminated with other doses of different degrees of size or from different types of rocks. Contamination is a serious problem of quality in the aggregated industry, especially if the finished product is used to produce cement, concrete and asphalt

statistics show that most of the aggregate is used up to 40 to 50 miles (64 to 80.5 kilometers) where it is produced. More than 90 percent are transported by a folder and some are transported by rail. It is a heavy material that produces a low price for a ton, so the price of the aggregate is strongly affected by transport costs.
