Cone crushers are used in secondary and tertiary roles as an alternative to impact crushers when shape is an important requirement, but the proportion of fines produced needs to be minimized. Impact crusher. An impact crusher uses mass and velocity to break down feed material.


Maximum feeding size is 600 x 350 mm. Thanks to special design of the tertiary impact crusher in the system, produced final fractions have excellent cubical shape which is a desired result especially for concrete production.


CRUSHER SELECTION QUICK GUIDE 1. A typical example of primary crushing is reducing topsize from 900 to 300 mm. 2. A typical example of secondary crushing is reducing topsize from 300 to 100 mm. 3. a typical example of fine crushing is producing concrete aggregates in fractions below 30 mm. 4.


The concrete with 40% of 3/8 mm fraction rolled gravel and 60% fraction crushed gravel showed a better performance than the control concrete in terms of the physical and the mechanical properties ...


The rotor impact mill is a high-performance crusher with a vertical shaft that addresses the needs of the recycling industry. The mill's unique impeller rotor works together with a toothed anvil ring to subject the inserted material to severe mechanical stress.


The non-magnetic product from an additional test was then used in combination with the coarser (+2.36 mm) unconcentrated fraction produced by a vertical shaft impact crusher in tests in concrete.

concrete fragmentation occurs via mechanical crushing and/or grinding, e.g., using impact crushing or jaw crushing [4]. The quality of these recycled aggregates is often suboptimal in view of replacing a large fraction of natural aggregates in new structural or non-structural concrete [5,6]. A high content of


Particle size distribution curves of recycled aggregates from concrete pavement crushed by jaw and impact crushers. The jaw crusher produced 85% coarse aggregates (fraction >4.8 mm), whereas the impact crusher produced 82% coarse aggregates. In both cases, the content of particles finer than 0.15 mm was less than 2% mass.


The first crushing process is performed with Primery Jaw Crusher, we can design with secondary impact crusher or cone crusher for second crushing stage according to the requirements of our customers. Fullstar-60 plant has been projected for the first time in the world by Fabo and provides crushing, screening and as well as to wash 0-5 mm sand ...


Maximum feeding size is 600 x 350 mm. Thanks to special design of the tertiary impact crusher in the system, produced final fractions have excellent cubical shape which is a desired result especially for concrete production. It is possible to get 3 or 4 different fractions at the same time.


Impact crushers rely on gravitational or dynamic physical impact for size reduction of materials such as rock, concrete, gravel, and more, rather than through a standard compression-only method of crushing. Typically, impact crushers either use gravity to drop material onto a surface, or the material is fed into a chamber containing a high ...


The main products are aggregates of three gauges: fractions > 45 mm (rank aggregates 1), fractions of 20-45 mm. (rank aggregate 2), and fractions of 0-20 mm. (rank aggregate 3). The secondary products are the fractions of steel reinforcing removed from concrete waste by
