Primary Dry Sampling
At our company, we specialize in the maintenance, installation, and refurbishment of primary dry sampling systems. These systems play a vital role in ensuring that representative samples are collected from dry material streams before further handling or processing.
Whether the sampler operates on a belt, within a chute, or under gravity flow, our team ensures that your equipment continues to perform accurately and efficiently. By maintaining and refurbishing your existing samplers, we help you avoid bias and ensure reliable sampling performance throughout your operation.
Our Primary Dry Sampling Capabilities
Comprehensive Maintenance:
We provide scheduled maintenance and inspections to keep samplers operating at peak efficiency, minimizing downtime and maximizing accuracy.
Professional Installation:
Our technicians handle complete installations for new or relocated systems, ensuring precise alignment, calibration, and integration with existing plant operations.
Expert Refurbishment:
We restore aging or damaged sampling equipment to like-new condition, extending service life and maintaining compliance with sampling standards.
Belt End Cross Cut Sampler
This sampler is mounted at the discharge end of a conveyor belt. As material falls off the belt, the sampler cutter traverses through the entire stream, collecting a full cross-section.
-
Custom designed for all discharge stream applications
-
Can be integrated into virtually any conveyor system
-
Handles high tonnages and coarse material sizes
-
Collects representative samples from the full belt width
-
Suitable for minerals, aggregates, and other dry bulk products
When to Use:
-
Where material is already discharging from a conveyor belt
-
For high-volume operations needing robust, heavy-duty equipment
-
To capture unbiased increments directly from belt discharge points
Hammer Cross Belt Sampler
Mounted directly onto an active conveyor, this unit takes samples as the belt runs. A hammer-type arm sweeps across the moving stream to remove increments.
-
Collects samples from full cross-sections of conveyed particulate streams
-
Proven reliability in high-tonnage coal and mineral operations
-
Designed for both light and heavy-duty use
-
Fully automated, low operator involvement
When to Use
-
When continuous conveyed material must be sampled without interrupting production
-
Particularly effective for coal, iron ore, and other conveyor-fed streams
-
In plants where integration into existing conveyor systems is required
Chute Cross Cut Sampler
Installed in vertical gravity-flow chutes, this sampler extracts increments by cutting across the falling material stream from side to side.
-
Flange-to-flange installation in chutes for neat, clean integration
-
Cuts across the entire falling stream for unbiased increments
-
Available in wear-resistant materials for abrasive ores
-
Can be designed for different chute diameters and flow rates
When to Use
-
For vertical gravity-fed material streams
-
When space or plant design makes conveyor sampling impractical
-
To achieve consistent, unbiased samples from falling bulk solids
Swing Arm Sampler
The swing arm sampler sweeps into the stream, collecting a portion and raising it for discharge. Known for its versatility, it can be designed for either light- or heavy-duty conditions.
-
Rotating arm swings through the product stream to collect increments
-
Handles high throughput with robust, low-maintenance design
-
Suitable for a wide range of particle sizes and material properties
-
Can be automated for timed or controlled sampling
When to Use
-
In bulk handling where flexible installation is required
-
Where both light-duty (fines) and heavy-duty (coarse ore) conditions exist
-
For plants requiring robust and repeatable mechanical operation
True-Belt® Sampler
A specialized cross-belt sampler, the True-Belt® design minimizes sample bias and reduces material loss. It increases integrity of samples by ensuring the full stream is captured without spillage.
-
Samples full cross-belt sections without bypass or bias
-
Improved sealing and mechanical design to prevent spillage
-
Maintains consistent, reproducible sample increments
-
Designed for integration into various conveyor systems
When to Use
-
In plants where sample quality and integrity are paramount
-
Where standard cross-belt samplers risk spillage or incomplete cuts
-
To meet stricter metallurgical accounting or QA/QC standards
Dry Vezin Sampler
The dry counterpart of the wet Vezin, this device takes a continuous sample and divides it into smaller increments for downstream handling. It is often used as a secondary stage but can also serve in primary dry streams.
-
Rotary cutter design divides material stream into representative portions
-
Division ratios typically range between 4 % and 20 %
-
Handles a wide variety of dry minerals and aggregates
-
Built in abrasion-resistant materials for long service life
When to Use
-
When a controlled division of dry streams is required
-
To complement other primary dry samplers as part of a staged system
-
In continuous operations requiring minimal maintenance
