MBE has in its product range, two types of environmental centrifuges, 2 Phase centrifuges & 3 Phase centrifuges.

Solid Bowl Centrifuges Co-Current design (2 Phase): The feed material is into solid bowl centrifuge with the aid of a pump. Progressive cavity pumps are commonly used for this duty, as they ensure a controlled uniform delivery of the feed. The feed rate may be ascertained with the aid of s flow meter in order to determine the throughput rate per hour or per day. The feed material is first pumped through a stationary feed pipe (1) into the feed compartment (2) which is located in the hub of the material screw conveyor (5) and within the field of centrifugal forces. The effect of these centrifugal forces causes the feed to flow through the feed compartment outlets (3) and into the bowl (4) of the solid bowl centrifuge.

The principal of co current flow starts the settling process as the feed enters at the large diameter end of the bowl. Solids and liquid are transported in the same direction. Hence, the complete bowl length is available for setting. This arrangement provides long settling distances and extended sedimentation time for the feed material to be dewatered or thickened. The settling operation proceeds uniformly, trouble free and with minimal turbulence.

The centrifugal force developed during normal operation causes the relatively heavy solid particles to settle on the bowl wall. These sedimented particles are transported inside the bowl by the screw conveyor (5) to the solids discharge point (7). Bowl and screw conveyor rotate in the same direction, but the screw conveyor speed slightly differs from that of the bowl. That differential speed is brought about by a suitable gearbox (6) by the corresponding transmission ratio of the V-belt drive, or through the utilization of s special hydraulic scroll drive system.

The separated solids are discharged through outlet openings (7) and are collected in casing (8). They are then routed through a chute to be discharged. The cent rate flows through the return channels (11) fixed to the conveyor hub in the opposite direction to that of the solids. The liquid leaves the centrifuge at the feed inlet end. This arrangement avoids interference with the sedimentation process, which normally occurs with the traditional countercurrent design.

The return channels for the cent rate discharge are sized so that the velocity of the flow substantially prevents the sedimentation of superfine solids contained in the cent rate against the interior walls of the channels. The cent rate is discharged over vertically adjustable weir plates (12) thus allowing for changes to be made to the cent rate level and consequently , altering the volume of the liquid retained inside the centrifuge. The cent rate is discharged through a chute. Visual inspection of the cent rate for the purpose of controlling the cent rate clarity is possible by taking samples at the machine outlet. Alternatively, provision can be made for automatic cent rate turbidity measurement and adjustment.

High Separation Efficiency: Solid Bowl Centrifuge is designed for Co-Current flow incorporating, long settling distance, high pool depth, longer dry beach and small angle. Hence, no turbulence will occur with high pool depth and long dry beach, ultimately extending the sedimentation time.
Low Power Consumption: These centrifuges are operated at low “G” force/low speed without turbulence and small beach angle. Hence, low power requirement about 08KWH.MH3 and low wear & tear without compromising efficient dewatering.
Optimum Cake Dryness: Cake dryness is optimized by varying the differential speed between 2-50 rpm by simply changing the pulleys.
Efficient Wear Protection: Conveyor flight and other wear prone parts are lined with tungsten carbide which is much more superior to standard stelite hard surfacing. The wear & tear of bowl shell is prevented by strip lining.
Easy Maintenance: MBE CMT Solid Bowl Centrifuge construction is simple with centralized lubrication system by which all the bearings can be lubricated while the machine is in operation.

Company Details

Since our inception, we have been associated with setting up of more than 50 Coal and Mineral beneficiation plants throughout the country with capacities starting from 0.25 to 8 MTPA making it one of the most promising names in the beneficiation sector. It also boasts to be the only company to have the technical expertise of both the proven technologies of beneficiation-Jigging and Heavy Media separation.
With Clients like Coal India Ltd., TATA Steel, Steel Authority of India, Bhushan Power and Steel Limited, Bhushan Steel Ltd and many more, we today render total beneficiation solution “from concept to commissioning” to most of the eminent names in the Core sector of Coal and Minerals rendering Design & Engineering services, Equipment Supply, Supervision of Erection and Commissioning and Operation & Maintenance.
MBE CMT is still known globally for its cutting edge technology products like BATAC© Jig, ROMJIG©, Pneumatic Flotation (Pneuflot©), Palla Vibrating Mill etc.: which have references across the Globe and has widely been appreciated by the consumers over the years. German engineering alongwith state of the art indigenous manufacturing facility gives the Client a combination best suited for his application. We also boast of our environment division manufacturing Solid bowl centrifuges for different applications with the Decanter capacity starting from 1 m3/hr to 30 m3/hr for solid-liquid separation particularly in the field of ETP, STP, CETP, WWTP, Chemical, Paper, Textile, Sugar, Mineral and Metallurgical Industries, Fertilizer Industries, Food Industries, Sewage, Water and Effluent Treatment Plant, Refinery & Petrochemical Industry, etc. having sold more than 1500 machines across the globe. MBE CMT India is also proud to have been associated with setting up of the first two non coking coal washeries set up in our country at Bina & Piparwar, both dedicated for supplying washed coal to the power sector and most of the milestones of the Indian beneficiation sector and now to add to the bouquet, MBE CMT India is about to commission the first Coal washery in Pakistan having completed the design & engineering and equipment supply for Tradeserve International, Karachi having received the order for the same in 2010. Apart from the above, MBE CMT India also supports Clients in EPCM (Engineering, Project & Construction Management) module. MBE CMT India is equipped with a State-of-the art manufacturing facility at Kharagpur for manufacturing of the main process equipment for Beneficiation plants. Further to the Kharagpur unit, the acquisition by the MBE group added another four magnificent production units at Bangalore, Baroda, Asansol & Kumardhubi to the manufacturing facility.
