The use of a good cement clinker grinding aid can be vital in todays increasing material demands.Along with the obligation to process increasingly larger quantities of ores containing finely disseminated minerals, our limited energy resources and the rising costs of energy present a challenge to the process engineer.One research route that has been explored for about half a century is the.
After the grinding process the additives might not be any longer in their original chemical form.In addition, grinding aid composition might not consist of mixtures of pure compounds, but rather more complex raw materials jeknavorian et al.1998b.The grinding aids such as alkanolamines and glycols are also widely used in other kinds.
Abstract a novel process for sulfidation of zno by co-grinding with sulfur and reductive additives p, fe, al, and mg was developed.The sulfidation extent of zno with the addition of p, fe, al or mg can reach 85.2, 81.6, 96.7 and 92.6 after grinding for 4, 6, 1 and 1 h, respectively.
With an abrasive sintered corundum al2o3 grinding set, the hard stems can be comminuted faster.The disadvantage of an abrasive grinding set is an early adhering of the particles even though a homogenous sample is achieved with a relatively close grain size spectrum, but with values in a coarser grain size range.
