BELT CONVEYOR DESIGN STANDARD

Conveyor is currently the most effective equipment for continuous transporting, lowering costs, automation of production line ad safe. Especially, through conveyor and the flat type conveyor, which is appropriate for transporting unpacked materials such as stinkstone and sand, have been developed therefore excellent in durability and cost efficiency.

Calculation of motor ability

The motor ability of 3 layered roller through 20° belt

Q＝A·V·r·60 · · · T/H
conveyor is calculated through the following formula. Refer to table 3 for motor ability for each belt's speed and width according to conveyor length when appearance is 1.0ton/m²

A, B, C indicates the measurement of belt at 20°, 30°, 30°

Motor ability calculated for the operation power

Q : Standard carrying capacity(t/h)     L : Horizontal carrying distance(m)
A=Cargo on board (m²) M : Weight of motor part apart from carrying materials weight(kg/m) (table 2) V : Belt Speed = appearance proprtion r = 외관비중 (t/m³) H: Lifting slope conveyor (m) f: 마찰계수(0.03) C : Modifier (table2) ㏋: Motor operation power(㏋) μ : Mechanical efficiency(0.7~0.8)
