Notes： If you need a belt conveyor solution, please be sure to first confirm the following information; wherever possible, provide relevant parameters, and leave any missing parameters blank.
📐 Conveyor Operating Conditions and Layout Parameters
Capacity: Annual capacity for material transportation，expressed in tons per h or tons per year; t/h Or t/y;
Length and horizontal conveyor distance: the distance between the axes of the head and tail rollers; if this exceeds 150 m, intermediate drive must be considered. M;
Lift height or inclination angle: When the inclination angle exceeds 12°, a check valve is required for upward transport; when it exceeds 18°, a ribbed belt or skirt baffle may be necessary. M or Degree;
Conveyance route: horizontal, uphill, downhill, or turning; whether there are convex or concave arc sections.(If you have a topographic map, you can provide it)
📋 Material Parameters
Material name and properties: Is it bulk material (coal, sand, gravel, grain) or unitized cargo (cardboard boxes, pallets)? Does it possess corrosive, adhesive, or flammable/explosive properties?
Loose density: Directly affects the calculated conveying capacity and motor power. kg/m³.
Maximum grain size/block size: Determines the lower limit of bandwidth; for example, with a bandwidth of 500 mm, the maximum block size is approximately 150 mm, while with a bandwidth of 1,000 mm, it can reach 300 mm.
Moisture content and temperature: These have the greatest influence on the maximum inclination angle; for standard tape, when the moisture content is ≤7%, the upper limit is approximately 18°.
📄 Environmental and Standard Documentation
Working environment: indoor and outdoor, temperature range, dust explosion protection class (e.g., for coal powder workshops, Ex d IIB T4 Gb), and coastal corrosion class. The max temperature is ℃， The mini temperature is ℃ ；
Power supply conditions: Whether it is 220V single-phase or 380V three-phase affects the selection of the motor.
Relevant standards: such as GB/T 10595-2025 "Belt Conveyors," DTII (Type A) Belt Conveyor Design Manual, CEMA, GIS, etc. (Can national standard materials be used, or can they be replaced with equivalent designs?)
⚙️ Structure and Selection Parameters
Bandwidth: Standard series sizes include 500,650,800,1000,1200,1400 mm, etc., which are jointly determined by the material block size and conveying capacity.(If applicable)
Conveyor speed: For bulk materials, typically 0.8–2.0 m/s; at port container terminals, it can reach 2.5–4.0 m/s.(If have)
Motor power: Calculated based on the conveying capacity, length, and lifting height; it must accommodate full-load start-up conditions.(If have)
Drive method: electric drum, motor + reducer, variable-frequency drive, etc.; these are affected by installation space and power capacity.(If have)
Idler arrangement: groove angle (standard 35°), diameter (89–159 mm), spacing (approximately 1–1.2 m for upper idlers and approximately 3 m for lower idlers). (If have)
Tensioning method: spiral, counterweight, or hydraulic; the tensioning stroke should be calculated based on the tape elongation.(If have)
