Conveyor 2B, 1200mm BW, plays a vital role in conveying material from wagon
tippler to main plant.
The conveyor had excessive spillage at the loading station, frequent damage of impact
idlers & return idlers and belt damage both at the center & edges.
Frequent engagement of manpower at conveyor site meant frequent shutdowns which
resulted in loss of productivity and huge container demurrage.
Tega’s Approach to Total solution:
Free falling large lumps damaged the impact idlers & the belt, while belt sagging due
to impact loading led to spillage. Friflo Impact Bed systems were suggested to absorb
impact and minimize belt sagging.
Multiple loading points with off-center loading was responsible for belt sway and
consequent belt edge damage. Tega Tracker Rollers were installed to check '
Ineffectiveness of conventional belt cutpiece scrapers led to excessive carryback
spillage& premature failure of return idlers. Hosch scrapers were recommended
to address the concerns.
Premature failure of 3 impact idlers in a month was eliminated.
Belt life increased to 18 months from 14 months.
Belt sway reduced from 100mm to 20mm on both the sides of the conveyor.
Monthly accumulation of spillage reduced from 70 tons to 12.5 tons.
Monthly engagement of manpower reduced from 17 man-days to 2.5 mandays.
Premature monthly consumption of return idlers reduced from 5 to 2.
