Big Bag Installations
Tailor made sampling installations for processing big bag applications and solutions
Laarmann Rotary Sample Dividers (up to 1600 Litres Volume) are an integral part of our big bag sampling solutions. The representative sampling of bulk materials is always a critical challenge. Especially when the sample has been transported for some distance (big bag) there is definitely segregation in the content and the chance of impurities is high. Experience shows that the bigger particles will be on top and the smaller particles will be at the bottom (brazil nut effect). We have integrated a piercing unit to get away from opening the big bag using a knife.
The 8 x 200 Litres divider module allows the batchwise dividing of:
Material into 8 x 200 litres fractions from a total lump volume of 1600 litres.

Big bag sampling installations
A sampling installation with big bags, also known as a bulk sampling system, is used in industries such as mining, agriculture, and construction to obtain representative samples of bulk materials stored in large containers or bags.
The installation begins with a dedicated area or station designed for unloading big bags.
This station usually consists of a sturdy support structure with a platform or frame to hold the big bags securely.
It may also include safety features such as dust extraction systems to minimize dust emissions during the unloading process.
A hoist or forklift is used to lift and position the big bags onto the unloading station.
The lifting mechanism should be capable of handling the weight of the big bags and ensure safe and controlled placement onto the station.
Once the big bag is positioned on the unloading station, a bag slitter or cutter is employed to open the bag and expose the bulk material inside.
This can be a manual or mechanical device that allows for controlled and precise cutting of the bag while minimizing the risk of contamination.
The sampling equipment is the core component of the installation and is responsible for extracting representative samples from the bulk material.
Various sampling techniques can be used depending on the nature of the material and the desired sample size.
Common sampling methods include rotary sampler dividers, cross-belt samplers, or vezin samplers.
The samples collected by the sampling equipment are typically directed to a collection point or sample container.
This can be a sample collection bin, conveyor belt, or sample transport system.
The collected samples may require further processing or preparation, such as crushing, grinding, or dividing, depending on the subsequent analysis or testing requirements.
To ensure the accuracy and reliability of the sampling installation, regular quality control checks and monitoring should be performed.
This may include verifying the sampling equipment's performance, calibration of instruments, and adherence to standard operating procedures.
Periodic maintenance and inspections are also essential to keep the installation in optimal working condition.
It's important to note that the specific design and configuration of a sampling installation with big bags may vary depending on the industry, material characteristics, and specific requirements of the application.
