Aggregate & Construction Aggregate

Aggregates are the raw materials for construction buiding, and they are inert granular materials such as sand, small-size gravel, or crushed stones. They along portland cement and water, are an essential ingredient in concrete making.Construction aggregate , or simply aggregate, is a broad category of coarse particulate material used in construction, including sand, gravel, crushed stone, slag, recycled concrete and geosynthetic aggregates.Aggregates are a component of composite materials such as concrete and asphalt concrete; the aggregate serves as reinforcement to add strength to the overall composite material.

Due to the relatively high hydraulic conductivity value as compared to most soils, aggregates are widely used in drainage applications such as foundation and French drains, septic drain fields, retaining wall drains, and road side edge drains. Aggregates are also used as base material under foundations, roads, and railroads. To put it another way, aggregates are used as a stable foundation or road/rail base with predictable, uniform properties (e.g. to help prevent differential settling under the road or building), or as a low-cost extender that binds with more expensive cement or asphalt to form concrete.

Cathay is a manufacturer of ballast crusher, and provide all kinds of gravel crushers and ore crushers for sale with best price, such as marble crusher, basalt crusher, bauxite crusher , Iron ore crusher , copper crusher and ballast crushing and screening plant. Railway and highway building is one of the most demanding applications for ballast.Ballast is produced from natural deposits of quartzite, granite, feldspar, dolomite, trap rock, basalt or limestone and so on.

Ballast crusher and ballast screen

Stone quarry use ballast crusher and ballast crushing plant to get ballast. Different type of crusher has different application. Ballast crushing and screening plant consists of Jaw crusher, standard cone crusher, short head cone crusher, impact crusher, VSI crusher, mobile Jaw crusher, portable cone crusher and mobile impact crusher. Besides, vibrating screen is used as sieving equipment, vibrating feeder as feeding equipment, belt conveyor as transferring equipment.

Jaw crusher is the most common crusher machine in quarry and used as primary crusher . Impact crusher or standard cone crusher are used as secondary crusher for crushing primary crushed rocks.The short head cone crusher is used as territory crusher.Ballast used for highway and railway is required to be cubic, so the ballasts have to be shapped through vsi sand making machine.Vibrating screen is used to screen out the suitable the stones.

Belt Feeder

The belt feeder structure consists of a conveyor belt carried by rollers. Belt feeders, which can be used to carry materials such as sand, lime, sawdust, cement, and ores, can be equipped with a hydrostatic drive system. This innovative system offers the full speed adjustability and extreme torque required to start the feeders under fully loaded conditions.
