“…Also, it should be pointed out that no product in any test experienced flake formation, which may be explained by the lack of moisture in the material, as it comes from electrofusion furnaces. This is an advantage from the operational and design standpoints, as flake formation may require additional equipment for it de-agglomeration, which impacts the operating and investment costs (Schönert, 1988;van der Meer and Gruendken, 2010) and the excess feed moisture may considerably reduce the equipment throughput (Saramak and Kleiv, 2013).…”

“…These are for instance, the 50% (or average) product size reduction ratio index, S 50% , the 80% product size reduction ratio index, S 80% , the 50% (or average) passing size of the product, P 50% , the 80% passing size of the product, P 80% [31] and the maximum product particle size, P max 10 [29]. All these parameters are based on empirical models.…”

“…For HPGR, these product quality indices have been found to be more dependent on the rolls operating pressure than the rolls speed [32]. When the rolls operating pressure is within its operating range, for a given moisture amount in the feed product, the product size reduction ratio index can be expressed as function of the rolls operation pressure through a linear relationship as [31]:…”
