Investigation of interparticle breakage as applied to cone crushing
网页1997年2月1日An analysis of a given crusher chamber gives selection values in the range 0.05 < S < 0.4. Given the geometry of this chamber it is clear that much of the breakage will be interparticle. However, the selection values indicate that the efficiency of crushing is poor. Using the approach outlined a mechanistic crusher model has been developed.

Understanding Comminution: Compression versus impact
网页2020年9月16日Jaw crushers are generally considered a primary or first-stage crusher. The maximum feed size can be as large as 80–85% of the crusher’s gape or depth, while reduction ratios range from 2–3 times. Cone crushers are typically used in the secondary or tertiary stage after a jaw crusher has begun the reduction process earlier in the circuit.

网页Our range of efficient Trio® cone crushers use compression force to break large rocks and other materials into smaller rocks, gravel and sand by squeezing the product between the mantle and liner.

High Pressure Grinding Rolls (HPGR) TAKRAF TAKRAF GmbH
网页Interparticle comminution is the HPGR specific grinding process in which material particles are crushed and ground within the compressed material bed and not by contact with the roll surface. Feed material can be smaller than the gap, which is an important distinction as compared to crushers, for example.

Understanding comminution: Compression versus impact crushing
网页This is because cone crushers like the Trio® TP series utilise interparticle crushing, where rocks are compressed against each other in addition to the crushing chamber and mantle, reducing the need for each rock to make contact with the crusher’s wear parts. This is called choke fed and an important operational aspect for the cone crushers.

网页One final factor towards cone crusher production is the level of material that is filling the chamber, or what is referred to as cavity level. As the cavity level increases in the crushing chamber, the bed of particles above the chamber help to push the ore through the chamber and increase interparticle comminution in the chamber due to elevated
