The effect of surface-active agents in improving the grinding efficiency for haematite, expressed as a measure of reduction ratio, has been studied. Drying of the feed before grinding has been found to improve the grinding efficiency.
About 2.3 million gallons of fluids per year of grinding fluids are incinerated. Grinding creates a significant environmental footprint, creating a need for methods to reduce energy use in grinding and for ways to recycle solid waste that would otherwise be sent to landfills or incinerated. by Beth Baniszewski. S.B.
Grinding is an ideal method for producing parts with a fine surface finish and high dimensional accuracy and for shaping hard or brittle workpieces. There are a wide variety of different types of grinding machines, each with different applications and slightly different energy requirements.

important environmental ramifications. For example, cutting fluids, with serious health and environmental issues stemming from their use and disposal, are often studied as an area for potential improvement. Various researchers have examined the benefits, drawbacks, and conditions necessary for both wet and dry machining [1-4].
Grinding is a common finishing process to meet specific technological requirements; however, it is energy, resource and time consuming. Thus, the improvement of grinding processes should not only consider the technological requirements but also environmental and economic impacts. There are a number of factors involved in grinding processes.
