The BAROID MUD CENTRIFUGE cuts mud costs by efficiently recovering valuable barite, rejecting unwanted solids arid providing better control of viscosity, gel, filtration rate and cake thickncss. When used as a desander, on low weight rnud, ihe centrifuge will remove solids without wasting valuable lluid.

A large throughput mud volume can be efficiently processed willi accurate control of output weight, Flow-ralors allow direct reading of mud and water volume, A tachometer provides continuous speed readings and total operating hours. All equipment has been specialty designed to reduce maintenance and increase efficiencv.

The BAROID MUD CENTRIFUGE is available in two models: Standard and Compact. Either model can be mounted on any mud pit or tank. The Compact unit can be installed iri an area as .small as 27" high, '13" wide and 90" long. Both units are powered by a dicscl, gasoline, natural ga3 or butane engine that is separately skid mounted and can he placed anywhere within fifty feet of ihe centrifuge unit. The mud to be processed is pumped to the centrifuge unit by a small portable pump that can easily be handled by two men. The pump can lie placed in ihe mud tank, pit or reserve pit.
