CRUSHED AGGREGATES are main products of our company sites. Crushed aggregates (stone) are produced from crushed rocks. They relate to loose inorganic materials and produced by quarrying of rocks with their further crushing, screening and sizing into various crushed stone fractions. Crushed stone is one of the most widespread and versatile construction materials.

base material. The stone that is too large to pass through the top deck of the scalping screen is processed in the secondary crusher. Cone crushers are commonly used for secondary crushing (although impact crushers are sometimes used), which typically reduces material to about 2.5 to 10 centimeters (1 to 4 inches).

The fraction of crushed stone is determined by the maximum size of an individual grain. Distinguish the most used of them: 5-20 mm
National Stone, Sand & Gravel Association says its member companies produce more than 92 percent of the crushed stone and 75 percent of the sand and gravel consumed annually in the U.S. More than 3 billion tons of aggregates were produced in 2005 at a value of approximately $17.4 billion.

Jaw Crusher vs Impact Crusher. In short, the jaw stone crushers are mainly used for primary crusher, the crushing stone is relatively large. The types of crusher machine''s chamber are deep and no dead zone. It improves that the feeding capacity and output. The crushing ratio is large and the product particle size is even.

Secondary crushing. The purpose of intermediate crushing is to produce various coarser fractions or to prepare material for final crushing. If the intermediate crusher is used to make railway ballast, product quality is important. In other cases, there are normally no quality requirements, although the product must be suitable for fine crushing.

Stone quarrying involves drilling, blasting, cutting, surface grinding and polishing and the crushing units produce different size fractions. These industries, particularly the crushers generate large quantities of particulate matters (dust). These particles pollute the air, water, land and vegetation at the sites and nearby areas.

This research involves the optimization of aggregate production using the Taguchi approach to maximize the production rate of Gneiss stone. The L18 orthogonal array has been used to investigate how the CSS, throw, eccentric speed, and particle size affect the products of the cone of the crusher (its cumulative weight fraction). The CSS, as well as the throw, eccentric speed, and particle size

Crusher capacities are based on a graded feed from the maximum size down to a minimum size approximately equivalent to the CSS. For instance, if the ROQ feed is from a gravel pit and you are producing a product less than 20mm is size and the raw feed contains 70% of natural occurring material of less than 20mm, this leaves only 30% to be crushed.
