The Pulley Diameter Analysis of the Belt Conveyor

In the designing of belt conveyor, the correct selection of pulley diameter is of great significance. The conveying belt use conditions improve with the increase of the pulley diameter. However, with the same other conditions, increasing the pulley diameter will correspondingly increase its weight, the transmission ratio,amount and size of the reducer. Therefore, the pulley diameter should not be too small to ensure delivery with normal operating conditions. Thus, traditional pulley diameter directly affects the whole cost and weighting the driving device of the conveyor belt.

In the selection of the pulley diameter, the factors below are generally considered:

1. The thickness of the conveying belt and the bending stress related to the thickness when it enlaces the pulley.
2. The total stress that the conveyor belt bears, including the pulling stress and the bending stress.
3. The maximum or average unit stress between the conveyor belt and the pulley surface.
4. The circle times that the conveyor belt bears bending load, the enlacing methods and number of its rolling the pulley.
5. The type of the conveyor belt and installation site.

Tripper Introduction

Belt conveyor tripper is a mobile device which can unload materials at the arbitrary point of horizontal section of the conveyor; it’s a single part of the conveyor. Movable tripper can be divided into light-duty type and heavy-duty type.
► Features
    1.Durable
    2.High efficiency
    3.Simple structure
    4.Stable operation
    5.Easy to maintenance
    6.Multiple discharging points
    7.Moving freely with wheels
 

tripper

► Advantage

    1.Heavy duty structural frames and supports – to provide system rigidity

    2.Heavy duty inlet skirting – to eliminate spillage at discharge transition

    3.Abrasion resistant belting – to reduce wear and increase life span

    4.Heavy duty idlers with anti-friction bearings – to increase idler life and reduce horsepower requirements

    5.High torque drive units – to power through upset conditions 

    6.Modular design shipped with limited field assembly required for drop in, bolt in place field installation

    7.May be fitted to any new or existing conveyor

    8.Single and dual side discharge designs

    9.Evenly distribution of materials 

    10.Save storage space

    11.Powered tripper movement through cable/winch assembly or powered wheels, crowned bend pulleys for positive belt tracking 

    12.Shuttling cross conveyor belt design available with side to side movement

    13.Cross over platform/operator deck available on cross conveyor tripper

    14.Engineered to meet new project requirements and also to retrofit existing conveyors

►  Application
XLP Tripper is always used at a large belt conveyor, it applies in the occasion where the belt conveyor has a discharge requirement, such as mining, power plant, steel plant, port, etc.
