1.1 This standard (Part IV) covers the following tests for aggregates concrete : a) Determination of Aggregate Crushing \‘alue, b) Determination of the 10 percent Fines Value, c) Determination of Aggregate Impact Vaiue, d) Determination of Aggregate Abrasion Value,
Impact crushers are used to created crushed rock aggregate. The different aggregate sizes and types are appropriate for specific uses in the construction and landscaping industries. For example, although the larger, coarse crushed aggregates are more economical, this type of aggregate can present problems if used in concrete forms for upright structures.
Mobile impact crushers. The mobile impact crushers MOBIREX are used in soft to medium-hard natural rock and in recycling. The capacity of the plants is enormous
Since the last century, 90 generations, the development trend of the concrete is the development of high-performance concrete, aggregates gradually as the main framework for the material, and the amount of cement as little as possible; impact crusher development must have a high-quality sand stone aggregate; concrete experts in China, the quality of the sand and gravel aggregate as a
WHAT IS AN IMPACT CRUSHER? The Aggregate Industry (Cement, Ready-Mix Concrete, Asphalt, Crushed Stone, Sand & Gravel), wants to process rock, sand, and gravel into a salable product as efficiently and inexpensively as possible. One such way to process these materials is sending gravel, rock, and sand through an Impact Crusher, which breaks up
Quarry & Aggregates. Recycling. Our philosophy is to build mobile crushing, screening and conveying equipment designed for the operator. We understand that being self-sufficient in your quarry operation heavily reduces downtime and costs. If your operator can maintain your excavator they can maintain a Striker.
Europe''s only true vertical impactor Magotteaux offers 3 models of vertical shaft impact crushers Mag’Impact® covering most crushing applications thanks to the remarkable flexibility and high capacity of the machine. The high quality materials produced by our Mag’Impact® allow customers to sell aggregates for concrete, asphalt, ballast and special products. This is possible thanks to the
Impact crusher is a machine that uses high speed impact energy rather than pressure to reduce material size. Applications widely utilized in aggregate, mining, energy, brick and so on industrial applications, depending to the type of an impact crusher, they can be used as a primary, secondary, or tertiary crushers to meet final-product-size needs.
Tertiary Impact Crushers Designed for crushing soft and medium-hard materials with close grain distribution and cubical products, MEKA tertiary impact crushers are an excellent solution in the production of fine aggregates for concrete and asphalt applications. More Information
Impact Crushers: the all-in-one rock crushing solution. The Sepro Impact Crusher is a cost-effective rock crushing solution designed for dependability and versatility. Fully-equipped to act as the primary crusher for limestone processing, concrete recycling, asphalt recycling, and more—the impact crusher can also function as a secondary crusher.
Ideal for crushing reinforced concrete and demolition waste, these impact crusher buckets are also in their element with bricks, natural aggregates, tiles, glass and asphalt slabs. It works fast and efficiently, with a drum design and a large mouth shape similar to a standard bucket.
The aggregate crushing strength value is a useful factor to know the behavior of aggregates when subjected to compressive loads. Also read: Crushing Value Test of Aggregates. 13. Impact Value. The aggregate impact value gives a relative measure of the resistance of an aggregate to sudden shock or impact.
Compression crushers require much less maintenance; high impact crushers undergo more wear and tear due to the material colliding within the crusher. Compression typically results in flatter output material whereas impact crushing creates a cubical material that may be higher quality for certain applications.
The most common concrete crusher machines: concrete jaw crusher, horizontal-shaft impact crusher, cone crusher, compound crushers, roll crushers, hammer crushers, etc. All machines are often manufactured to a mobile or portable crushing equipment when recycling concrete because mobile crushers can move freely and work efficiently in harsh environments.
This paper compares the use of jaw and impact secondary crushing for producing coarse recycled aggregates from concrete wastes, obtained from road pavement and demolished building materials.

Impact crusher, jaw crusher, cone crusher or sometimes manual crushing by hammer are preferred during primary and secondary crushing stage of parent concrete to produce RA. Based on the available literature step by step flowchart for recycling of aggregate is represented in Fig. 1 .

Recycled concrete aggregates require more energy to crush than recycled mortar aggregates, a finding primarily related to the aggregate size of composite cement particles. Improvement in the segregation of cement paste tends to enhance the recycled aggregate quality and use under different stress conditions, such as compression, impact and shearing.

In concrete aggregate processing line, the work of the portable concrete crusher for sale is crushing. The aggregate produced by crusher machine can be used to produce concrete, brick and so on; the mortar can be used to lay block and wallboard, etc; the stone screened by construction waste can be used to pave road and so on.
The gravel is then sprinkled with water and enters the tertiary crusher (secondary impact crusher); which is the last crusher used in the chain. After this the crushed stone is conveyed to a separator having three decks.(32mm, 12mm, and 5mm top to bottom) The aggregates greater than 32mm will be taken on the top sieve and cycle back to secondary impact crusher for further action.

(secondary aggregates) from concrete waste. Concrete recycling plants carry out various processes, such as classification and separation of materials, crushing of concrete waste, and internal transport. The Outputs of the Subsystem The outputs consist of the principal products, the secondary products, the emissions and the residues or waste.
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 construction is expressed by numerical index.
