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
Grinding aid or grinding additives refer to substances which when mixed into the mill contents cause an increase in rate of size reduction [1]. These terms are very common in cement industries where it is used to increase the throughput to the mill. Grinding aid also affect the cement flowabilitiy throughout the circuits.
The major aim of a precision grinding wheel is to use the wheels of different composition. This produces metals with different shapes. The grinding wheels obtained of different shapes like round, square, cup and dishes. Grinding wheels are ideal for a wide range of materials and can perform hard grinding of tools, like steels and other metals.
