The MDX can tackle a variety of applications, but it is especially suitable for hard rock comminution. Hard rock mining requires the use of one or more grinding stages for reducing crushed run-of-mine ore down to a suitable particle size for liberating the product from gangue materials. The MDX has consistently met customer expectations within the following applications:
Semiautogenous (SAG) and ball mill circuits: In SAG operations, both balls and the ore itself assist in the grinding process. This mechanism is used in mining operations that require grinding to finer particle sizes, need high capacity, or need to grind multiple types of ore at once. The MDX can help operators tackle these applications by reducing their consumption of lining plates and grinding media.
Ball and rod mill discharge: Rod mills are best in wet applications, where the slurry has up to 50% solids by mass; however, they can be used in dry applications as well. The MDX pump’s hard metal construction resists damage in the event of rod tangling.
Cyclone and screen feed: In this application, cyclones separate heavy from light slurry components. There are a variety of design principles that go into cyclones to achieve various cuts of the media. Pressure drop across the cyclone is defined by a variety of parameters both intrinsic to the cyclone/separator and the pump feeding it. The MDX pump is designed to achieve the total head to the cyclone, plus the calculated or predicted pressure drop across the cyclone.
