Calculation of Aggregate Crushing Value. The crushing value of aggregates is measured in the ratio between the crushed aggregates, obtained from the IS sieve 2.36mm and the weight of the dried aggregate sample. At least three samples should be tested from the same batch and average value to get accurate results. Thecrushing value of aggregate = (W2/W1) x 100. Lab Report
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.
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.
An impact crusher is a piece of heavy construction equipment people can use to reduce the size of things like rock, waste concrete, and similar materials.
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.
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 convery belt is mainly composed by the expansion cylinder on both ends and the closed belts tightly knotted on them.
This testing method is known as an aggregate crushing value test. Aggregate crushing valuetest provides the resistance of an aggregate sample to crushing under gradually applied compressive load. Generally, the test is conducted on aggregate passing 12.5 mm and retained on 10 mm sieve.

It is recommended that the crushing value of aggregate should be less than 30%. 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% can be used for wearing surface.
