Bulk Material Handling Calculators
Preliminary capacity, pile storage, conveyor, feeder, elevator, chute and dust-control calculations with selectable units, independent history and working reset controls.
Clickable combined-equipment workflow
Bulk Material Handling Design Flow
Follow one integrated sequence from material characterization and storage through equipment selection, conveyors, feeders, elevators, transfers, dust control and final verification. Each button opens the existing calculator.

Engineering boundary: final design requires representative bulk-solid testing, approved project requirements, vendor data, structural/dynamic design, combustible-dust assessment and responsible-engineer approval.
Methods, standards and limitations
- CEMA: use the project-specified edition of Belt Conveyors for Bulk Materials and equipment-specific CEMA publications for final selection.
- DIN 22101 / ISO 5048: use the controlled project edition for final belt-conveyor resistance, power and tension calculations.
- Bulk solids flow: final mass-flow hopper and outlet design requires representative material testing, including wall friction and cohesive strength. Published density and angle values are preliminary only.
- Pneumatic conveying: not included as a simple calculator because solids pressure drop, saltation and pickup velocity require validated correlations or specialist software.
- Dust hazards: combustible-dust evaluation, explosion venting, isolation and suppression require the applicable project and safety standards.
- Final equipment selection must use manufacturer data, actual particle-size distribution, moisture, abrasiveness, lump size, loading conditions and approved project specifications.
Important: These calculators are preliminary engineering screens. They do not replace material testing, vendor selection, dynamic conveyor analysis, structural design, combustible-dust assessment or the controlled edition of the governing standard.
