The Bangalore unit of MSEL manufactures a range of process equipment, largely catering to the Mineral Processing Industry, but also finding applications in other sectors.
Hydrocyclones
MSEL manufactures a range of Cyclones catering to the Mining and Minerals Sector.
MSEL Cyclones are designed to withstand the severely abrasive conditions experienced in most mining and metallurgical applications. MSEL Cyclones are suited for the replacement of mechanical classifiers in closed circuit grinding installations. Sound design and competent technical service have permitted our Engineers to introduce the Cyclones into virtually all fields of wet mineral processing. The Hydrocyclones could be employed in various processes like closed circuit wet grinding, de-watering, de-sliming, classifying to produce various size fractions etc.

Column Flotation cell
MBE-NML Column Flotation
National Metallurgical laboratory is one of the renowned laboratories in India dedicated for continuous research
and development in the field of Metallurgy and Mineral beneficiation. We are proud to be their partners in the
Journey of building column Flotation cell. After successful lab, pilot scale testing and various commercial scale
installations, we introduce MBE-NML column Flotation cells to the world of processing industries.
McNally Bharat Engineering Company Ltd. (MBE) is one of the leading Engineering Companies in India engaged
in providing turnkey solutions in the areas of Power, Steel, Aluminium, Material Handling, Mineral Beneficiation,
coal washing, port cranes, civic and industrial water supply etc. Over 300 plants have been constructed on
turnkey basis by MBE till date.
The basic Success of any Flotation cell lies in the fact that the bubbles meet hydrophobic particles of the feed and carry them to overflow. For this to happen it is always better to create more no of bubbles and also of finer size and that’s what column Flotation does.
The conditioned feed enters the column at about two thirds height. The unique sparger system specially designed by NML-Chennai, installed at the bottom generates bubbles with sufficient kinetic energy & of finer size so as to trap all the hydrophobic particles. The design of column Flotation ensures that there is enough time for the particles to come in contact with the bubbles and carry them to the overflow. The hydrophilic particles settle down at the bottom which is discharged.
The mineralized bubbles reach the upper portion of the column, i.e. cleaning zone, they encounter a blanket of wash water which sweeps away gangue and slurry water entrapped in the froth.

High Rate Thickeners
High Rate Thickener (HRT) is a relatively old concept in the world market by now. HRTs with interestingly different design features, have overcome many of the disadvantages of a conventionally designed thickener. The improved design features have been helpful in reducing the size of HRT by 1/3 to 1/2 the size of the Conventional Thickeners. This new generation of Thickeners dramatically increases the throughput capacities, significantly decrease the space requirement and substantially economize the investments and operational costs. Its unique feed system totally eliminates the conventional free settling stage, overcomes the problems of High polymer consumption and poor process control inherent in the other designs.
MSEL can offer the following range of thickeners -
Conventional Thickeners/ Clarifiers
High Rate Thickeners/ Clarifiers
High Compression Thickeners
MSEL can also upgrade existing Conventional design to a High Rate or a High Compression design.
Centrifuge Gravity Concentrator
MSEL represents M/s Falcon Concentrators Inc. Canada for their range of centrifugal concentrators. These may be of semi batch type SB machines used largely in recovery of fine gold or the C type continuous machines, which can be used in the recovery of fine minerals from a slurry stream.
Filters
MSEL has tie-up with Larox, Netherlands for the following range of filters:
Vacuum, drum & disc filters
Pressure Filters
Horizontal Belt Filters
Ceramic Filters
Suitable filters for any given application will be chosen based on tests and the size and type best suited for the given application will be offered.
