The phosphogypsum crystals formed during this chemical reaction are discarded, and the phosphoric acid is further processed to form the finished fertilizer product. 23:8882 000 01218cam a22003498a 4500 001 3868979 005 20150630165646.

Previous efforts to reduce grinding media consumption were mainly on finding the most wearresistant metal, e. In fertilizer plants, phosphate is used to produce phosphoric acid by reacting phosphate with sulfuric acid. 1 Mils is one thousandth of an Inch or 0. Thousands of tons of grinding media are consumed in phosphate chemical plants every year, and reduced wear and corrosion rates will significantly reduce the grinding costs and improve the grinding efficiency by maintaining optimal grinding ball size.

Comminution operations are the most expensive and energy consuming in the mineral industry. It is used to calculate the material loss or weight loss of a metal surfaces. A range of ferrous grinding media compositions was subjected to laboratory marked ball wear tests in an ongoing research program at the Mineral Resources Research Center which was aimed at elucidating the responsible wear mechanisms during the grinding of minerals.

The corrosion process of steel slow down at pH values greater than 9. This report presents data collected during research by the Bureau of Mines on corrosion of grinding media. The direct operating costs in grinding are mainly the energy consumed and the metal lost through wear and corrosion. ABSTRACT The concern regarding grinding media consumption rates is as old as the invention of the tumbling mill.

Most of the wear data in this paper were obtained using a model quartz-pyrrhotite mineral slurry but these have been supplemented, where appropriate, with a small amount of data from wear tests on taconite ore and a Cu-Ni gabbroic ore.high-chromium alloys, and sig.

To increase the chemical reaction rate, phosphate rock is ground to fine particle sizes prior to the chemical reaction process. This figure is most important to calculate the life time of a pipe. Corrosion rates of eight alloys commonly used in grinding media were tested in synthetic mill water using an ultrasonic grinding device especially Corrosion rates of grinding media in mill water for this work.
