Dense-graded aggregate (DGA): Also known as "crusher run" or "road stone," DGA is a mix of crushed stone and stone dust. The stone dust fills the voids between the crushed stone, providing a more stable and compact base. This material is excellent for driveways, as it can withstand heavy loads and provides a smooth, even surface for the concrete.
Above, a truck feeds Crusher #1, the first in a series of crushers that the stone passes through. This quarry produces 18 different aggregate products that vary in size from boulders to sand. Looking directly down into Crusher #1, the size of the stone before it enters the crusher is visible. The stone is moving from left to right.
The purpose of the primary crusher is to reduce the ROM ore to a size amenable for feeding the secondary crusher or the SAG mill grinding circuit. The ratio of reduction through a primary crusher can be up to about 8:1. Feed: ROM up to 1.5 m; Product: -300mm (for transport) to -200mm (for SAG mill) Feed Rate: 160 to 13,000 tph

The secondary crusher housing is a rugged, fabricated steel plate construction with heavy external bracing for increased strength and stability. For quick and easy inspection of the internal wear parts, the housing is fitted with large doors which are opened and secured by …
With impact crushing, the stone breaks along its natural cleavage lines, resulting in a more cubical product, which is desirable for many of today's specifications. HSI crushers can be primary or secondary crushers. In the primary stage, HSIs are better suited for softer rock, such as limestone, and less abrasive stone.
Ideally, the deck on the scalping screen should have a cut point equal to the closed side setting (CSS) of the crusher. The feed size to a secondary crusher is typically in the range of 50 mm to 250 mm (up to 300 mm). If the capacity is …

Secondary Crusher. As the name suggests, secondary crushers follow the primary crushers and are used to further reduce the size of the material. They are designed to handle medium-sized materials and produce a finer output compared to primary crushers. Tertiary Crusher. Tertiary crushers are employed when further reduction in size is required.

Dear Colleagues, The construction industry is considered one of the most important sectors of socio-economic development. However, its dynamism gives rise to two major environmental issues: (i) a significant increase of construction and demolition waste (CDW), which represents more than 30% of the solid waste generated by all economic sectors, and (ii) an …
Typically, contractors gravitate to impact style concrete crushers because impact crushers are capable of producing a DOT spec base material (e.g. ¾"-) and add a jaw crusher as a primary crusher to increase total production output later on. A jaw crusher stand-alone comes in handy if you need to produce a 3"- non-spec product.
