Determining the Volume of Rejected Granules in the Recycling Silo

This article reviews the application and challenges involved in detergent production and shows how 3D level measurement can be used to accurately determine the quantity of rejected granules in the recycling silo.

Dry Ingredients

Dry ingredients are stored in silos before being sent to the production process.

Detergent production

In order to ensure sufficient inventory for the production process, the contents of the dry ingredient silos needs to be accurately measured.

The 3DLevelScanner from BinMaster employs multiple-point surface mapping technology to create accurate volume and level data for separate silos in real time. This process improves the end users’ ability to efficiently control inventories and restock silos in a timely manner.

Finished Product

The end product is generally kept in the silos before being packaged and shipped.


To ensure the availability of products for the packaging process, the end user need to accurately track the inventory of the final products. However, it can be difficult to measure the end product, because it has a tendency to pile unevenly in the silo.

The 3DLevelScanner from BinMaster is designed to accurately determine the volume and level of the contents within the silos. This enables the end user to efficiently control inventory management and delivery schedules, and improve the reliability of associated financial reporting.

Reject Recycle Silo


The dried granules are normally screened to acquire a comparatively standard size. Granules exceeding the standard size are not screened and sent to a storage silo, and later recycled back to the crusher for additional processing to meet the standard size of granules.


Dust is created by the rejected material as it is loaded onto the silo. Granules that are unevenly shaped are likely to build up at the base of the silo and form an uneven topography on the surface of the material.

This means that the end user is required to constantly track the volume of material stored in the silo and slowly reintroduce it into the manufacturing process, while ensuring that the silo is not overfilled.

Material buildup should be identified as quickly as possible so that scheduled cleaning and maintenance operations can be implemented in a timely manner. This ensures that the material flows freely from the silo and costly stoppages of the manufacturing process are prevented.

BinMaster’s 3DLevelScanner has level and volume measurement capabilities along with optional 3D visualization tool, which enable constant monitoring and early detection of material buildup.
