This article discusses the applications and challenges involved in lime production, and shows how 3D level measurement can be effectively used to detect material buildup and rat holes before they become an issue. Figure 1 displays a layout of the lime production process.

Crushed Limestone Silo

After the limestone is mined, it is crushed and kept in silos prior to entering the kiln.

Challenges

During the filling and emptying process, lime creates a large amount of dust. The material can become sticky and accumulate on the walls of the silo.

As lime is a raw material, operators have to constantly track the inventory levels to ensure a steady supply in the limestone production process.

The 3DLevelScanner system from BinMaster provides accurate volume measurement, even in adverse environments. This can be attributed to its 3D surface mapping capabilities and unique dust-penetrating technology.

The 3D visualization tool offers a real-time 3D display, allowing operators to view the actual distribution of the contents stored in silos, and enabling early detection of material buildup as it occurs. This also allows operators to schedule timely maintenance within the silos to prevent unforeseen process interruptions and related losses of money and time.

Quicklime Storage

Quicklime powder and quicklime granules are typically kept in silos prior to delivery for different applications.

Challenges

During the filling and emptying process, quicklime granules and quicklime powder create a considerable amount of dust and become sticky, leading to buildup and rat holes. In order to prevent disruptions of the production process and delivery schedules, operators have to track and regulate the amount of the material left in the silo.

The advanced surface mapping technology of the BinMaster 3DLevelScanner provides accurate, reliable, and real-time volume measurement of the quicklime inventory, considering the uneven material buildup, even under adverse environments.

The 3D visualization tool of the scanner displays the topography of material within the storage bin, enabling operators to quickly detect material buildup as it occurs. This will allow operators to schedule timely maintenance, so that unanticipated and costly interruptions of the manufacturing process can be prevented.

Slacked Lime Powder

Slacked lime is kept in silos before being packed and delivered.

Challenges

Slacked lime is a very fine powder, and during the filling and emptying process it creates a considerable amount of dust. It also tends to become sticky, leading to buildup and rat holes.

Normally, operators have to track and regulate the amount of the slacked lime left in the silo to prevent disruptions of the production process or delivery schedules.

The advanced surface mapping technology of the BinMaster 3DLevelScanner provides accurate, real-time volume measurement of the slacked lime inventory, considering the uneven material buildup even under adverse environments.

The 3D visualization tool of the scanner shows the topography of material within the silo, enabling operators to quickly detect material buildup as it occurs. This will allow operators to schedule timely maintenance and prevent unpredicted and costly disruptions of the production process.
