AGGREGATE & INFRASTRUCTURE
Aggregate Production is consisting of following activities-
Drilling & Blasting
Shot Rock or Gravel Bank creation
Secondary & tertiary crushing
Sizing & Grading.
Crushed sand of size 0-2.36 and 0-4.75 mm
Its screening process depends on products size
Stockpiling & Handling
Finished product stock of various size
Stocking bins of various size
Final products of Aggregates of various sizes
Following MSEL equipment cater to above processes in Aggregate Production-
Apron Feeders are extensively used to reclaim ROM/ Large Size rocks from Dump Hoppers for primary crushing at quarry end Stone Handling.
Jaw Crushers are used as primary crushers in aggregate production. Either Single Toggle or Double Toggle Jaw Crushers are selected based on hardness and mineralogy of stones.
Toothed Double roll crusher are used as secondary crushers in aggregate plants to crush (-) 25 mm size and smooth double roll crushers can be used for producing (-) 5 mm size of soft and medium soft rock.
Cone Crushers & VSI
MSEL has agency agreements with reputed manufacturers to sell Cone Crushers & VSI equipment, which are required in secondary crushing to produce aggregate of size 0 – 40 mm and 0 – 63 mm (GSB) & tertiary crushing (-30/ 10 mm) of stones for subsequent reduction to even smaller sizes.
Bucket Elevators are used for vertical transport of powdery, small grained bulk materials e.g. raw meal, cement, sand, grits, Salt etc.
Conveying system & Conveyor Components
MSEL product range includes all types of drive and non-drive pulleys, and idlers. Conveying systems are designed based on capacity, type of material & stocking criteria
Reciprocating Feeders are built for high capacity reclamation from surge bins, bunker and hoppers. A wide range of sizes is available in MSEL offerings. Heavy Duty versions with larger drives and heavier pans can be selected for coarse Stones and normal versions for fine Stones.
Rotary Disc Feeders
Rotary Disc Feeders are continuous volumetric device reclaiming dry small lumps, coarse, fine grained and powdery material e.g. river bed gravel, sand, alumina etc. from surge bins and hoppers to feed subsequent equipment.
Grizzly Screens/ Feeders
Grizzly Screens/ Feeders are used in primary crusher operation in Quarry Mining as scalping screen downstream of the Primary Crusher to separate undersized and oversized Stone. This also separate fines/dust from the feed before crushing & avoid contamination. Typical separation is at 80 mm. Grizzly Screens/ Feeders are also used as Feeders to reclaim Stone from Hoppers/Bins.
Also known as CM Screens, Circular Motion Screens are used to segregate various size fractions in Stone 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 the crusher. Circular Motion Screens 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 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 are ideally suited for heavy and very heavy screening applications for fine grain size materials (3 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 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 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.
MSEL has a large range of skid mounted and wheel mounted Crushing & Screening plants in various configurations to suit multiplicity of sized products in various capacities catering to production of coarse, medium and fine aggregates and road stratum material.
MSEL Roll Crushers are suitable for making crushed sand. Roll crushers are suitable in secondary & tertiary stage.
