Grinding Mill Media

Phosphate rock is the raw material used in the manufacture of most commercial phosphate fertilizers. In its unprocessed state, phosphate rock is not suitable for direct application, since the phosphorus it contains is insoluble. This rock is derived from naturally-occurring ores. To transform the phosphorus into a plant-available form and to obtain a more concentrated product, phosphate rock is processed using sulphuric and/or phosphoric acid. The process begins by grinding phosphate rock to a fine material. Primary size reduction generally is accomplished by grinding mill media.

Grinding mills are commonly used in the phosphate industry to reduce particle size. Our grinding mill media meets your grinding and dispersing requirements with a full line of the highest quality grinding. Our skilled technical service representatives are always available for consultation and ready to assist you with the selection of media they best answer your particular needs.

The corrosion of metallic grinding media and mill liner is a very serious problem, particularly in acidic conditions as encountered in the phosphate fertilizer industry. Approximately 50% of the total wear of grinding mill media can be attributed to metal corrosion. It is known that the corrosive wear of grinding mill leads to a loss of process efficiency, operating cost and plant downtime, and product contamination. An effective protection of grinding mills from corrosion will improve the process performance and economics, increase the lifetime of mills and grinding media and enhance product quality and that's primary for us.
