To Develop Modified Belt Convener For Specific Application (IDP)  We have considered slippage of the belt while transmitting the material from one station to the other is for project work. As the slippage leads to loss of power without any transmission. So that problem was under our focus. 7

BELT CONVEYOR 8

 Flat belt conveyor : A conveyor having a moving flat belt carried on free running rollers Is know has flat belt conveyor.  Some term: Head Roller: The terminal Roller at the discharge end of the conveyor is know as head roller. Tail Roller : The terminal Roller at the loading end of the conveyor is know as tail roller. 9

BELT CONVEYOR BASIC PRINCIPLE  Belt conveyor working on “ Open belt drive ”.  Belt conveyor is one type of Material handling and transporting equipment.  Belt Conveyors move under principles of friction drive 10

TYPES OF CONVEYOR  Slider Bed Belt Conveyors,  Chain Conveyors,  Roller Bed Conveyors,  Bucket Conveyors,  Screw Conveyors,  Roller Gravity Conveyors. 11

APLICATION OF BELT CONVEYOR  Belt conveyor use constantly operating equipment which is mainly used to convey mass bulk material like mineral, coal, sand, etc in powder or block as well freight in metallurgy, mining, building heavy industries and transport action industry. 12

CAUSES OF THE SLIPPAGE IN THE BELT  In this context,we have noticed various possible causes of the slippage of the belt. They are as under:- 1.Miss alignment of the driver and driven shaft, 2.Effect of temperature on belt under tension so some permanent deflection of belt so starts slipping, 3.Over load in belt so deflection of belt so starts slipping etc,. 13

GENREL CHECK SLIP EQVATION  Approximately no loss in motor R.P.M. & Torque so very much slip is not produce.  But approximately losses in motor R.P.M. & Torque so very much slip is produce. 16

HOW TO ACTIVE SLIP ? 17

PROBLEM SOLUTION  To show graph we will focus on the alignment of the belt, behavior of the material of the belt at different temperature and also on the safe amount of load that may not result in any slippage. 18

PROBLEM SOLUTION(1)  Also in the modification of the system we will install a idler pulley to tighten the belt as per requirement and to avoid slip. 19

 Also one of the pulley may be modified and lead screw type arrangement can be provided which can be moved in the direction which will oppose the slip. PROBLEM SOLUTION(2) 20
