Safe, accurate sampling from moving conveyors

Our range of cross belt systems are safe and reliable and offer unprecedented accuracy for your sampling operations. These systems can be configured to your needs, ranging from single-stage sampling to multistage systems, and incorporate crushing, discrete sub-sampling and reject handling. Importantly, they be completely automated to run continuously to help improve your productivity while reducing costs.

This range of samplers has been successfully implemented at a wide variety of mines, docks, ports and power plants worldwide. They can be used to sample coal, coke, crushed stone and a variety of ores, and can be easily retrofitted to your existing conveyer via a straightforward installation procedure.

Naturally, all our Cross Belt Sampling Systems come with the backing of FLSmidth and JBLCo’s integrated design and manufacturing capabilities. You’ll benefit from our research and development programs as well as our product, engineering and manufacturing teams. And you’ll have access to ongoing 24/7 support from our experts. 

Automated sampling saves time and money

Our Cross Belt Sampling Systems can be operated both manually and automatically, depending on your needs. By automating your system and configuring it to run continuously, you’ll be able to lift the performance of your sampling operations while saving money on operator costs.

Automating your system will also remove the need for manual “grab” samples, which will help increase the safety of your employees. It also keeps your conveyor on the move by reducing the need for stop-belt sampling.

Easily configured to your needs

Our systems are available in both single and multistage systems and can be configured to the needs of your operation. Contact us today to speak to one of our experts about how our Cross Belt Sampling Systems could fit with your existing operations.

Straightforward installation into existing plants

Installing new sampling systems into existing material handling infrastructure can sometimes be a massive challenge – especially when finding enough height to install a falling stream sampling device. Cross belt samplers can be easily and inexpensively retrofitted to existing conveyor systems. These top-of-the-belt sweep samplers are designed to mount on the top chord of your conveyor and usually retrofit to the conveyor truss between existing 35-degree idlers.

Primary sampling

The primary sweep sampler is mounted on the customer conveyor and will automatically take and discharge samples from the conveyor based on a pre-set time. Input data is transmitted to a system PLC to confirm a sample is ready to be taken.

Picksizer

The picksizer is usually mounted after the primary sampler to break or crush any large sampled material to a nominal 50 mm top size. This material can then be handled and metered through the remainder of the sampling system for a more uniform sampling operation. The picksizer will run continuously whenever the system is on and in automatic mode.

Sample crusher

The sample crusher is designed for quick and easy interior access. It is a hammermill-type crusher with 6mm AR-225 liners in wear areas.

Crushed material feeder

The crushed material feeder is used to accept nominal 12mm material from the sample crusher. A conveyer transports the sample flow away from the sample crusher for sub-sampling or final sample collection. Flow-controlling baffles are used to make a uniform material x-section as the flow leaves the feed area.

Bucket elevator

The bucket elevator collects all the sample material rejected from the sampling system and transports it vertically back to the original material flow of the sampled conveyor. This elevator is typical used on systems where limited floor space is available for standard conveying systems or the rejected material has to be lifted to an extreme height.

Secondary sampling

The secondary sampler is mounted on the crushed material feeder and will automatically take and discharge samples from the conveyor whenever the sampling system is in automatic operation mode. Like the primary sampler, it is controlled via a system PLC. The cutter is driven by a reversing gear brake motor that allows discharge of samples into two different discharge containers.

Sample collection carousel

The sample collection carousel is mounted under the secondary sampler. This unit, also controlled via a system PLC, will automatically position sample collection containers according to the instructions of the operator HMI. The containers can be positioned by vendor number or by number of samples collected.
