Applying discrete element modelling to vertical and ...
For low rotational speeds, fragmentation initially did not occur until it impacts on the crusher anvil. Forces induced into the crusher anvil were always higher than that induced from the impacting impeller. As speed of the impeller increases, initial impact becomes a significant cause of fragmentation. These effects are demonstrated in Fig. 12.

Downstream Effects of Cave Fragmentation | SRK Consulting
To simulate the effect on SAG mill performance, these fragmentation curves were passed through a primary crusher model. As shown in the figure, the variation in mill feed (80% passing size, in mm) is evident as the cave propagates upward and the secondary fragmentation generates more fines and a .

Cave fragmentation in a cavetomill context at the New ...
Fragmentation measurements, from sieving and imagebased methods, as well as historical logs of hangup events are presented. Measurements showed that for the B1 and B2 caves, secondary fragmentation size, representing the size of material at drawpoints, is strongly related to faulting, height of draw and effects of the cave boundary.

HABITAT FRAGMENTATION AND THE EFFECTS OF ROADS .
Habitat fragmentation creates landscapes made of altered habitats or developed areas fundamentally different from those shaped by natural disturbances that species have adapted to over evolutionary time (Noss and Cooperrider 1994 in Meffe et al. 1997). Adverse effects of habitat fragmentation to both wildlife populations and species include:

EFFECTS OF HABITAT FRAGMENTATION ON BIODIVERSITY
Abstract The literature on effects of habitat fragmentation on biodiversity is huge. It is also very diverse, with different authors measuring fragmentation in different ways and, as a consequence, drawing different conclusions regarding both the magnitude and direction of its effects. Habitat fragmentation is usually defined as a

What Is Habitat Fragmentation? |
Habitat fragmentation occurs when a habitat is altered or disjointed. As a result, there is a spatial separation in a habitat that redistributes the species and organisms within the habitat. Habitat fragmentation may occur naturally or as a result of humans.

Rock Fragmentation Control in Blasting JIM
Rock fragmentation is not well understood, and research on predicting and controlling fragmentation is warranted. In this study, fragmentations for five models, which consider the effect of specific charge and geometry in bench blasting, are examined.

IMPACT OF ROCK HARDNESS ON FRAGMENTATION BY .
The rock blocks extracted by blasting which are larger than the opening of the primary crusher are usually fragmented by hydraulic hammer. The paper presents the results of the testing of impact of rock hardness on fragmentation of rocks by means of hydraulic hammer and during crushing in jaw crusher.
