Factors affecting cost:

1. TPH Needed = bigger wider screen box needed, bigger shafts, bigger bearings, bigger sideplates, more steel to build, bigger heavier structure to hold the heavier vibrating body, with more safety factor built into it.

2. Bigger motors needed to drive, more static wgt, consuming more energy per hr, per day, per week, month, etc = higher operating cost per tph

3. Bigger vibrating screens......ie....8x24 3 deck, 14-20 tons of vibrating wgt require more engineering knowledge to create structure

4. More maintenance required ...due to bigger strains on bearings, shafts, sideplates, wear part areas, requiring more money to maintain and probably more experienced mtce staff to operate and maintain same

5. Horizontal or flat screens are generally more costly to buy, more costly to run and more costly to maintain. Gears, bearings, twin shafts, higher operating G's , shorter bearing life than other styles, more costly to install, operate, etc.

6. If fine screening.....typically need to buy many units to screen high tonnages, requiring more structure to support, more attention to closeness of units to avoid sympathetic vibration problems, more feed chutes, more discharge chutes, more catwalks, etc etc.........very costly factors

This is just a view points to ponder......many many more for sure
