May 05, 2010· Coarse aggregate crushing value is thepercentage by weight of the crushed material obtained when test aggregates are subjected to a specified load under standardized conditions. Aggregate crushing value is a numerical index of the strength of the aggregate and it is used in construction of roads and pavements.
Hongxing cone crusher is used for crushing ores and rocks and the advantages are reliable structure, high efficiency, easy adjustment and economy.
Vibratory feeder in the production line can transport the material with the shape of massive and particles smoothly to the feeding device in a stable time.
The circular vibrating screen is a vibrating screen with high efficiency and it advantages include stable structure, strong exciting force, high efficiency, low vibrating noise, durability, handy maintenance and safe operation.
This series of jaw crusher belongs to stone crushing equipment which is widely used in the works of metallurgy, mining, cement, chemistry, refractory and ceramics as well as highway construction and water conservancy.
The convery belt is mainly composed by the expansion cylinder on both ends and the closed belts tightly knotted on them.
The combination crusher is a new generation high efficiency crushing machine designed and researched by integrating the domestic and foreign crusher technology with the same kinds and optimizing the main technical parameters.
AGGREGATE CRUSHING VALUE This test helps to determine the aggregate crushing value of coarse aggregates as per IS:2386 (Part IV) –1963. The apparatus used is Cylindrical measure and plunger, Compression testing machine, IS Sieves of sizes – 12.5mm, 10mm and 2.36mm. Procedure to determine Aggregate Crushing Value
