Apron Feeders

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

Jaw Crushers

Jaw Crushers are used as primary crushers in Rock Phosphate Mining.

Roll Crushers

Corrugated Double Roll Crushers are used as secondary crushers in Rock Phosphate plants to crush (-) 25 mm size. Smooth Double Roll Crushers can be used for crushing up to (-) 5mm.

Cone Crushers

MSEL has agency agreements with reputed manufacturers to sell Cone Crushers equipment, which are required in tertiary crushing (-30/10 mm) of Rock Phosphate for subsequent grinding to even smaller sizes.

Chain Mills

Chain Mills are special size reduction equipment in Fertiliser segment for reducing (-) 75 mm feed to (-) 6 mm lumps.

Conveyor Components

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

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.

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

Circular Motion Screens

Circular Motion Screens are used to segregate various size fractions in various mineral streams. Sometimes Circular Motion Screens are used to reduce load on crushers by removing fraction which is already smaller than required size and sometimes Circular Motion Screens are used to recirculate oversize fractions from crushed product stream back to crushers. Possible application is in Mines before despatch to power 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.

High Particle Acceleration Screens

High Particle Acceleration Screens are ideally suited for screening applications for higher level of moisture and fine grain size materials (3 mm to 10 mm) with screening capacities up to 250 metric TPH. In Iron Ore & Steel industry High Particle Acceleration Screens are used for fine screening in Flux Crushing & Screening circuits. The Inner frame is agitated by means of eccentric shaft drive. The vibration is passed on to the Outer frame via flexible thrust springs.

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.

Slurry Pumps

In Rock Phosphate 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 downstream Ore beneficiation.

Flotation Cells

Flotation Cells are used for Silica removal as underflow in first stage of flotation, whereas Phosphates and Carbonates are extracted as froth.

In second stage additional bank of Flotation Cells are used to remove carbonate (rejects) as froth and Phosphate Concentrates as underflow, which is then processed through cleaner flotation Cells before taking for thickener concentration and filtration.

Banana Screens

Banana Screens are multi-slope vibrating screens, come in single/ two 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.


  • Thickeners are used to concentrate silica Slurry (30-35% Solids) underflow from first flotation stage to about 60- 70 % Solids before sending Thickener underflow to tailings disposal as rejects. Thickener Overflow product is mostly water and is recycled into grinding circuit.
  • Another set of thickeners are used to process Carbonate froth from Second stage flotation, recycling the thickener overflow as Process water and sending thickener underflow as tailings for reject disposal.

Vibrating Tube Mills

Vibrating Tube Mills are for continuous or batch grinding of materials to a very fine end product. Two vibrating/ grinding cylinders are placed either directly above the other or inclined at 30 degrees to perpendicular. Located between the two tubes, an eccentrically supported weight is driven to produce a small circular vibration. The tubes are charged with ball or rod media to aid in the grinding action (attrition) from the constant impulses. Material is ground as it travels from the input end of the tube to the outlet end.

Vibrating Tube Mills have a very small size and low energy consumption compared to other mill types and are used in manufacture of paints and varnishes where ultra- fines (of the order 10-20 microns) are required. Output is restricted to 5-10 tph. We offer Vibrating Tube Mills from our Baroda plant.
