Rotary Sample Divider 5L Hopper 6-60 RPM 10 Collection Cans for Mining Laboratories

The benchtop rotary sample divider is built for laboratories that cannot accept a biased split. A 5 L feed hopper discharges crushed material into a rotating 10-can carousel running at a stepless 6–60 RPM, so every increment of the batch meets the cutter under the same conditions — from the first can to the last.

Feed geometry, rotation speed and the fixed 1:10 dividing ratio stay repeatable run after run, which is what laboratory QA systems and third-party auditors look for when an assay result has to be defended. With a 3–13 mm feed size range and stainless steel product contact parts, it handles crushed ore, drill core, coal, clinker, slag, cement and aggregate samples without introducing iron contamination into the sub-sample.

• Corrosion and rust resistant construction Main body and all product contact parts are stainless steel. Samples pass through the divider without picking up rust, paint or carbon steel wear, which matters for trace element and iron content analysis.
• Stepless speed control from 6 to 60 RPM Rotation speed is adjusted continuously to suit feed size, bulk density and material flow. Coarse crushed ore and light, free-flowing powders each get a speed that fills the cans evenly instead of overflowing them.
• Compact benchtop layout with semi-enclosed dividing head The low-profile bench design saves floor space in small preparation rooms. The semi-enclosed housing lets the operator watch the dividing process, gives straightforward access for cleaning and maintenance, and limits dust escape at the same time.
• Ten collection cans, 6 L each A full carousel of ten cans means the entire batch is divided in a single pass with no intermediate handling. Cans lift out individually for labelling, weighing and further reduction.
• Fixed 1:10 dividing ratio The cutter geometry is set at the factory, so the ratio between feed and sub-sample is constant. Repeatability comes from the machine, not from the operator's judgement.

Specifications can be adapted for OEM projects — tell us your sample type, feed size and required sub-sample mass and we will confirm the suitable configuration before quoting.

• Mining and mineral processing — crushed ore, ROM samples, concentrate and tailings reduction ahead of assay.
• Geological and exploration laboratories — drill core and rock chip sample splitting into reference and pulp portions.
• Coal and coke testing — dividing crushed coal for proximate, ultimate and calorific value work.
• Cement, clinker and slag — preparation of representative sub-samples for XRF and wet chemistry.
• Metallurgy and recycling — slag, sinter, alloy and scrap sample reduction.
• Third-party inspection and university laboratories — repeatable splitting where results may be challenged or compared between operators.

1. Load. Pour the crushed sample, up to 5 L and within the 3–13 mm range, into the feed hopper.
2. Set the speed. Dial the rotation between 6 and 60 RPM to match the material; the divider runs at a constant rate while the carousel turns beneath the cutter.
3. Divide. Each pass cuts the full sample stream at a fixed 1:10 ratio and distributes it across the ten collection cans.
4. Collect and label. Lift out the cans, take the portion you need for assay and retain a reference portion for re-checking.

Tell us the material you prepare, your feed size and the sub-sample mass your assay method requires, and we will confirm the right configuration, lead time and price for your laboratory.
