Jaw Crushers

Jaw Crushers are used as primary crushers in Bauxite Plants and also for spent anode butts.

Apron Feeders

Apron Feeders are extensively used to reclaim ROM/ Large Size ores from Dump Hoppers for primary crushing at mine end Ore Handling.

Apron Conveyors

Apron Conveyors are used for conveying spent Anode Butts for recycling in Anode Paste Plants and are quite similar to Apron feeders in many respects, however Apron Conveyors may be of curved alignment and long lengths (say up to 100 M).

Toothed Double Roll Crushers

Toothed Double Roll Crushers are used in crushing spent anodes in Anode Paste Plants of Aluminium Smelters.

Conveyor Components

MSEL product range includes all types of drive and non-drive pulleys, and idlers.

Motorised Trippers

Basically Motorised Trippers are rail mounted conveyor discharging equipment to uniformly distribute the conveyed Ore over a large Bin or Ground Storage stockpile.

Grizzly Screens/ Feeders

Grizzly Screens/ Feeders are used in primary crushing operation in Bauxite Mining as scalping screen of the Primary Ore Crusher to separate undersized and oversized ore. Typical separation is at 80 mm. Grizzly Screens/ Feeder are also used as Feeders to reclaim ore from Hoppers/Bins.

Rotary Disc Feeders

Rotary Disc Feeders are continuous volumetric device reclaiming dry small lumps, coarse, fine grained and powdery material e.g. coke breeze, ground bauxite, alumina etc. from surge bins and hoppers to feed subsequent equipment.

Circular Motion Screens

Circular Motion Screens are used to segregate various size fractions in ore streams. Sometimes used to reduce load on crushers by removing fraction which is already smaller than required size at other times Circular Motion Screens are used to recirculate oversize fractions from crushed product stream back to crushers. Possible application is in Mines before despatch to beneficiation plants as also in beneficiation plants. Circular Motion Screens are available in 1, 2 and 3 decks to get 2, 3 and 4 size fractions respectively. Each size fraction may be requiring different post processing.

Linear Motion Screens

Linear Motion Screens are used for similar applications but in more demanding situations, e.g.-

  • Where the height is limited by surrounding facilities,
  • For the screening of small and short fractions
  • Where required throughput is high.

High Particle Acceleration Screens

Also known as Flip Flo Screen, High Particle Acceleration Screens are ideally suited for screening applications for fine grain size materials (3 mm to 10 mm) with high moisture and screening capacities up to 250 metric TPH. The outer frame is agitated by means of eccentric shaft drive. The vibration is passed on to the inner frame via flexible thrust plates.

Screening mats between the inner and outer frame are clamped and flexed by the two vibrating frames. The relative movement of both screening frames creates a “trampoline effect” in the screen mats to create-

  • High acceleration up to 50g in screen mats.
  • Loosening-up and de-agglomeration of the product.

Banana Screens

Banana Screens are multi-slope vibrating screens, come in single/ two/ three deck configurations and are used in place of Circular Motion Screens when higher capacities (above 400 tph) are to be processed. The angle of deck decreases from feed end to discharge end.

Cone Crushers

MSEL has agency agreements with reputed manufacturers to sell Cone Crushers equipment, which are required as Secondary (-150/ 75 mm) and Tertiary Crushers (-30/ 10 mm) in Bauxite Crushing for Alumina production.

Reciprocating Feeders

Reciprocating Feeders are built for high capacity reclamation from surge bins, bunker and hoppers and also as feeding equipment. A wide range of sizes is available in MSEL offerings. Heavy Duty versions with larger drives and heavier pans can be selected for coarse ores and normal versions for fine ores

Bucket Elevators

Bucket Elevators are used for vertical transport of powdery, small grained bulk materials e.g. raw meal, cement, sand, grits etc. They are used in filling tall bauxite and alumina silos.

Slurry Pumps

In Beneficiation plants usually the process involves transporting of Ore Slurry (suspension of Crushed/ Ground Ore in Water) between various stages. This is done by use of Slurry Pumps. MSEL has a vast range of Horizontal and Vertical Centrifugal Pumps catering to Slurry Pumps requirements.

Rod Mills (Grinding Mill)

Final crushed ore from tertiary crushers is ground to (-) 1 mm by rod mills. MSEL has a large range of rod mills to suit most ore characteristics and product requirements.

Ball Mills (Grinding Mill)

Ball Mills (Grinding Mill) are used for size reduction to microns and form part of grinding circuit to get the final product for calcining or Alumina refining Process. Ball Mills (Grinding Mill) are also used in Coke Grinding for Carbon Paste preparation in Aluminium Smelters.


Thickeners are used to concentrate alumina Slurry (30-35% Solids) from refinery to about 60- 70 % Solids. Overflow product is mostly water and is recycled into circuit whereas the underflow is taken for evaporation circuit or to tailings as reject disposal.


We can offer the Beneficiation/Up gradation solution for the Bauxite ore through flotation as part of total solution for this plant which will include Crushing, Grinding, Flotation, thickening, dewatering (Filtration), slurry pumping and system integration and plant design.
