Jaw Crushers

Jaw Crushers are used as alternatives to Gyratory Crushers as primary crushers in Zinc, Lead, Copper and Gold Mining when the throughput needed is less than 500 – 600 metric TPH. For hard ores Double Toggle Jaw Crushers and for softer ores Single Toggle Jaw Crushers are customary.

Apron Feeders

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

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.

Cone Crushers

MSEL has agency agreements with reputed manufacturers to sell this equipment, which are required as Secondary (150/ 75 mm) and Tertiary Crushers (30/10 mm) in Beneficiation circuits.

Conveyor Components

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

Rod Mills (Grinding Mill)

In most of Zn-Pb-Cu-Au mining circuits, final crushed ore from tertiary crushers is ground to (-) 1mm by rod mills. Where High Pressure Grinding Rolls are used secondary and tertiary crushing as well as rod milling is dispensed with. 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 a grinding circuit in Ore Beneficiation Plant. In Zn-Pb-Cu-Au mining circuits ball mills grind rod mill products or products from High Pressure Grinding Rolls to (-) 75/40 microns and create slurry of 30-35 % solids concentration.
Ball Mills (Grinding Mill) are also used as regrind mills in Flotation Circuits.

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 and 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 and 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.

Rotary Disc Feeders

Rotary Disc Feeders are continuous volumetric device reclaiming dry small lumps, coarse, fine grained and powdery material from surge bins and hoppers to feed subsequent equipment. Rotary Disc Feeders can be used in chemical conditioning slurry tanks for dosing reagents.

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

High Particle Acceleration Screens are ideally suited for screening applications for for higher level of moisture and fine grain size materials (1 mm to 10 mm) with screening capacities up to 250 metric TPH. The Inner frame is agitated by means of eccentric shaft drive. The vibration is passed on to the Outer frame via thrust rubbers.
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.

Grizzly Screens

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

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

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.


Thickeners are used to concentrate Ore Slurry (30-35% Solids) from various stages of flotation to about 60- 70 % Solids. Overflow product is mostly water and is recycled into circuit whereas the underflow is taken for filtration (in case of Concentrate Thickeners) or to tailings as reject disposal.

Flotation Cells

Flotation Cells are used for removal of specific impurities ore separation of different metallic particles from multi-metal ore slurries. Tests determine the size and configuration of the Flotation Cell Banks.

Filter Press

We offer MSEL-Choquenet Filter Press for dewatering of concentrate or tailing in Beneficiation Circuits.
