20231213 · Auxetic metamaterials, which exhibit the negative Poisson’s ratio (NPR) effect, have found wide applications in many engineering fields. However, their high porosity inevitably weakens their bearing capacity and impact resistance. To improve the energy absorption efficiency of auxetic honeycombs, a novel vertex-based hierarchical star …

The majority of the quarries (1, 3, 4 and 5) applied secondary crushing, i.e., the production included two crushing units. Quarries 2 and 6 applied tertiary crushing, relying on three and four crushing units, respectively.
view moreA disadvantage is the low productive capacity, determined by the slow working speed. In crushing by cutting, selection can be made between single-shaft, two-shaft or four-shaft shredder (Vatskicheva et al. 2013). The single-shaft shredders (fig. 1b) are rarely used for this type of materials crushing, because of their low productive capacity.
view moreThe roller crushers are used for moist and sticky materials. Generally the machines have to be rigid enough to crush also hard inclusions. As the reduction ratio is only about 5:1 a 2-stage crushing is required in most applications. Fast running type crushers like hammer and impact crushers are the simplest and cheapest solution, whenever the ...
