The ‘ aggregate crushing value test `gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. Aggregate crushing value is defined as the percentage by weight of the crushed (or finer) material obtained when the test aggregates are subjected to a specified load under standardized conditions, and the strength of the aggregate used in road …
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 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.
The hammer crusher, also named heavy hammer crusher, crushes by the collisions between high-speed hammer and materials. It has features of simple structure, high reduction ration, high efficiency, etc.
The convery belt is mainly composed by the expansion cylinder on both ends and the closed belts tightly knotted on them.
Linear vibrating screen is widely used for screening any dry materials whose diameter is 0.074-15mm and the biggest feeding granularity is less than 20mm.
Mobile crushing station, which is also called portable crusher, incorporates all the equipment together on one truck, which has high chassis, narrower body compared with other trucks.
It is recommended that the crushing value of aggregate should be less than30%. If it is more than 30 % then 10% finer aggregate is suggested to use. The aggregate whose crushing value is less than 30% can be used for cement concrete road. The aggregate whose crushing value isless than 40…
