适用范围:1.1 This standard provides guidance for selection and design practices to be adopted for belt conveyors.1.2 This standard applies to stationary and shiftable conveyors handling loose bulk material and such material which behave as solids. For guidance, classification and properties of such material are covered in IS : 8730-1978'Classification of bulk materials handled by continuous mechanical handling equipment'.1.3 This standard covers the conveyors with belt widths ranging from 300 mm to 2 800 mm as currently in vogue in conformity with relevant Indian Standards but excluding special purpose conveyors.Note 1—Conveyors, not covered under this scope and special purpose conveyors, for example, feeders, package conveyors, etc, will be covered in a separate standard.Note 2 —This standard also covers the conveyors uisng steel cord belting.Note 3 — Special requirements for conveyors for use in underground coal mines are also covered by this standard.Note 4 — This standard does not include certain data on steel cord conveyors and conveyors for underground mines where relevant Indian Standards are not available.1.4 Attention is drawn to the many varied factor which influence the driving force on the driving pulley and which make it extremely difficult to predict the power requirement exactly. This Indian Standard is intended to give a simple method of conveyor design calculation. Consequently it is limited in terms of precision but is sufficient in the majority of cases. Many factors are not taken into account in the formulae but details are provided on their nature and their effect. In simple cases, which are the most frequent, it is possible to progress easily from the calculation of power requirements to those of the necessary and the real tensions in the belt, which are critical in the selection of the belt and in the design of the mechanical equipment. However, certain conveyors present more complicated problems, for example those with multiple drives, or with an undulating profile in vertical elevation. For these calculations, which are not covered in this Indian Standard, it is advisable to consult a competent expert.1.5 The recommendations given in this standard shall be applied both to individual conveyors, as well as conveyor systems consisting of more than one conveyor. Care shall however be taken to apply clauses pertaining to system requirements.1.6 This code covers the belt running on idler rollers only and not on slides/beds.1.7 This standard applies for only smooth surfaced belt.
