the primary function of idler rolls in a belt conveyor system is to support the conveyor belt along its length. predicting the cumulative resistance of idler rolls is vitally important in calculating the belt tension and therefore power requirements of a system, particularly on long overland conveyors where there are typically more than one thousand idler rolls per kilometer of belt.

a variety of analytical and computational methods exists for calculating the indentation rolling resistance of conveyor belts. these include both one- and two-dimensional analytical approaches (refs. 5-9), and two-dimensional finite element methods (refs. 10-12). one-dimensional winker foundation models provide a simple and direct way to
pipe belt conveyor is a new type of environmentally friendly and efficient bulk conveying equipment. in the design of the roller, the belt and the driving motor of pipe belt conveyor, the sag resistance is a key parameter. meanwhile, the normal force between the conveyor belt and the roller group is the other important factor need be considered and has a great influence on the sag resistance.

low rolling resistant conveyor belts. frictional resistances in a belt conveyor system is one of the major factors contributing to higher power consumption. one of the major frictional resistances is indentation rolling resistance (irr), where a resistance to belt motion arises due to the indentation of belt bottom cover over the idler roll.

under this circumstance, indentation rolling resistance which makes up a relatively significant share (61%) among the running resistance of belt conveyor 1 has a need for further study to achieve energy saving. 2 as shown in figure 1, when conveyor belt passes over a series of idlers, indentation rolling resistance is defined on account of
conveyor includes the indentation rolling resistance (irr), the running resistance of the conveyor belt around the roller, the impact of the materials and the bending resistance of the conveyor belt [1]. among them, the indentation rolling resistance is the largest, and the energy it consumes accounts for about 60% of the total energy

it is important to know how the indentation rolling resistance depends on the belt velocity to enable selection of a proper belt velocity, [11]. figure 3: loss factor (tanb) of typical cover rubber [7] firstly, the indentation rolling resistance depends on the vertical load on the belt, which is the sum of the belt and the bulk material weight.
transevo tm. transevo covers are based on a special rubber compound which significantly reduces rolling resistance due to indentation losses while the belt is running over the idlers. transevo achieves energy savings of up to 25% compared to conventional conveyor belts without compromising on the belt
belt, and the indentation rolling resistance due to the indentation of the idler rolls into the belt. the indentation rolling resistance of pipe belt conveyors is higher than the indentation rolling resistance of conventional open trough belt conveyors. in case of the latter, it may already form up to 61% of the total rolling resistance [1].
the various resistances are belt includes the critical parts like roller, roller shaft, supporting rolling conveyor, sliding resistance of conveyor, bending brackets, l channel base frame which directly affects on resistance, idlers turning resistance, flexure resistance of bulk excess use of material with increase in costs, so that power
