Determines the bulk density of building lime by allowing the material to fall from a standardized height into a calibrated container, providing reliable mass-per-unit-volume values essential for production control and conformity assessment.
Used to characterize how lime behaves in storage, conveying and dosing systems, supporting the design and verification of silos, hoppers, feeders and packaging units by basing all calculations on the actual bulk density of the product.
Assists in the correct sizing and capacity calculation of mixing and batching equipment for lime and lime-based mortars, ensuring mixer volumes, feeding systems and weighing arrangements are matched to real bulk density rather than idealized theoretical values.
Follows the EN 459-2 test principle in which a lime sample is discharged from a hopper through a flap or trap, falling freely from a fixed height into a volumetric cylindrical container, then leveled and weighed to calculate bulk density in kg/m³.
The combination of cylindrical litre vessel, intermediate piece with flap and spring-loaded release mechanism ensures uniform filling conditions, reduces operator influence, and improves repeatability and reproducibility between different laboratories.
Specifically developed for building limes as defined in EN 459-1, the apparatus is suited for quality control in lime production plants, independent laboratories, and institutions performing research and development on lime and lime-based materials.
The mechanical, power-free design makes the apparatus robust, simple to install on a standard laboratory bench, and easy to maintain, while remaining fully compatible with standard laboratory balances and ancillary cement and lime test equipment.
